To open a database:
var db = null;
document.addEventListener('deviceready', function() {
db = window.sqlitePlugin.openDatabase({name: 'demo.db', location: 'default'});
});
IMPORTANT: As with the other Cordova plugins you must wait for the deviceready event. This is especially tricky in Angular/ngCordova/Ionic controller/factory/service callbacks which may be triggered before the deviceready event is fired.
To populate a database using the standard transaction API:
db.transaction(function(tx) {
tx.executeSql('CREATE TABLE IF NOT EXISTS DemoTable (name, score)');
tx.executeSql('INSERT INTO DemoTable VALUES (?,?)', ['Alice', 101]);
tx.executeSql('INSERT INTO DemoTable VALUES (?,?)', ['Betty', 202]);
}, function(error) {
console.log('Transaction ERROR: ' + error.message);
}, function() {
console.log('Populated database OK');
});
To check the data using the standard transaction API:
db.transaction(function(tx) {
tx.executeSql('SELECT count(*) AS mycount FROM DemoTable', [], function(tx, rs) {
console.log('Record count (expected to be 2): ' + rs.rows.item(0).mycount);
}, function(tx, error) {
console.log('SELECT error: ' + error.message);
});
});
To populate a database using the SQL batch API:
db.sqlBatch([
'CREATE TABLE IF NOT EXISTS DemoTable (name, score)',
[ 'INSERT INTO DemoTable VALUES (?,?)', ['Alice', 101] ],
[ 'INSERT INTO DemoTable VALUES (?,?)', ['Betty', 202] ],
], function() {
console.log('Populated database OK');
}, function(error) {
console.log('SQL batch ERROR: ' + error.message);
});
To check the data using the single statement API:
db.executeSql('SELECT count(*) AS mycount FROM DemoTable', [], function(rs) {
console.log('Record count (expected to be 2): ' + rs.rows.item(0).mycount);
}, function(error) {
console.log('SELECT SQL statement ERROR: ' + error.message);
});
See the Sample section for a sample with a more detailed explanation.
before_plugin_install hook to install sqlite3 library dependencies from cordova-sqlite-storage-dependencies via npm.6.3.0) is recommended. Cordova versions older than 6.0.0 are missing the cordova-ios@4.0.0 security fixes.before_plugin_install hook.

Ideally you should be able to handle a callback with some data coming from a prompt.These prereqisites are very well documented in a number of excellent resources including:
More resources can be found by https://www.google.com/search?q=cordova+tutorial. There are also some tutorials available on YouTube.
In addition, this guide assumes a basic knowledge of some key JavaScript concepts such as variables, function calls, and callback functions.
MAJOR TIPS: As described in the Installing section:
--save flag when installing plugins to track them in config.xml. If all plugins are tracked in config.xml then there is no need to commit the plugins subdirectory tree into the source repository.platforms subdirectory tree into the source repository.NOTICE: This plugin is only supported with the Cordova CLI. This plugin is not supported with other Cordova/PhoneGap systems such as PhoneGap CLI, PhoneGap Build, Plugman, Intel XDK, Webstorm, etc.
Use the following command to install this plugin from the Cordova CLI:
cordova plugin add cordova-sqlite-storage --save
Please see the Installing section for more details.
Try the following programs to verify successful installation and operation:
Echo test - verify successful installation and build:
document.addEventListener('deviceready', function() {
window.sqlitePlugin.echoTest(function() {
console.log('ECHO test OK');
});
});
Self test - automatically verify basic database access operations including opening a database; basic CRUD operations (create data in a table, read the data from the table, update the data, and delete the data); close and delete the database:
document.addEventListener('deviceready', function() {
window.sqlitePlugin.selfTest(function() {
console.log('SELF test OK');
});
});
NOTE: It may be easier to use a JavaScript or native alert function call along with (or instead of) console.log to verify that the installation passes both tests. Same for the SQL string test variations below. (The Windows platform does not support the standard alert function, please use cordova-plugin-dialogs instead.)
This test verifies that you can open a database, execute a basic SQL statement, and get the results (should be TEST STRING):
document.addEventListener('deviceready', function() {
var db = window.sqlitePlugin.openDatabase({name: 'test.db', location: 'default'});
db.transaction(function(tr) {
tr.executeSql("SELECT upper('Test string') AS upperString", [], function(tr, rs) {
console.log('Got upperString result: ' + rs.rows.item(0).upperString);
});
});
});
Here is a variation that uses a SQL parameter instead of a string literal:
document.addEventListener('deviceready', function() {
var db = window.sqlitePlugin.openDatabase({name: 'test.db', location: 'default'});
db.transaction(function(tr) {
tr.executeSql('SELECT upper(?) AS upperString', ['Test string'], function(tr, rs) {
console.log('Got upperString result: ' + rs.rows.item(0).upperString);
});
});
});
It is recommended to read through the usage and sample sections before building more complex applications. In general it is recommended to start by doing things one step at a time, especially when an application does not work as expected.
The new brodybits / Cordova-sqlite-bootstrap-test sample is intended to be a boilerplate to reproduce and demonstrate any issues you may have with this plugin. You may also use it as a starting point to build a new app.
In case you get stuck with something please read through the support section and follow the instructions before raising an issue. Professional support is also available by contacting: sales@litehelpers.net
window.sqlitePlugin.openDatabase static factory call takes a different set of parameters than the standard Web SQL window.openDatabase static factory call. In case you have to use existing Web SQL code with no modifications please see the Web SQL replacement tip below.androidDatabaseImplementation option in window.sqlitePlugin.openDatabase)code member is bogus on Android and Windows (fixed for Android in litehelpers / Cordova-sqlite-evplus-legacy-free, GPL or special commercial license options).androidDatabaseImplementation: 2 (built-in android.database implementation) option is used.Some more known issues are tracked in the open Cordova-sqlite-storage bugs.
db=window.sqlitePlugin.openDatabase({name: ':memory:', ...}) is currently not supported.\u2028 (line separator) and \u2029 (paragraph separator) characters are currently not supported and known to be broken in iOS version due to Cordova bug CB-9435. There may be a similar issue with certain other UNICODE characters in the iOS version (needs further investigation). This is fixed in: litehelpers / Cordova-sqlite-evplus-legacy-free (available with GPL or special commercial license options)\u0000 (same as \0) character not working in Android (default Android-sqlite-connector database implentation) or Windows\u2028 line separator / \u2029 paragraph separator fixes) in: litehelpers / Cordova-sqlite-evplus-legacy-attach-detach-free (available with GPL or special commercial license options)androidDatabaseImplementation: 2 (built-in android.database implementation) option is used.window.sqlitePlugin object is not properly exported (ES5 feature). It is recommended to use andpor / react-native-sqlite-storage for SQLite database access with React Native Android/iOS instead.Some more limitations are tracked in the open Cordova-sqlite-storage bugs.

To verify that both the Javascript and native part of this plugin are installed in your application:
window.sqlitePlugin.echoTest(successCallback, errorCallback);
To verify that this plugin is able to open a database, (named ___$$$___litehelpers___$$$___test___$$$___.db), execute the CRUD (create, read, update, and delete) operations, and clean it up properly:
window.sqlitePlugin.selfTest(successCallback, errorCallback);
IMPORTANT: Please wait for the 'deviceready' event (see below for an example).
window.openDatabase() factory call with window.sqlitePlugin.openDatabase(), with parameters as documented below. Some other known deviations are documented below. Please report if you find any other possible deviations.NOTE: If a sqlite statement in a transaction fails with an error, the error handler must return false in order to recover the transaction. This is correct according to the HTML5/Web SQL API standard. This is different from the WebKit implementation of Web SQL in Android and iOS which recovers the transaction if a sql error hander returns a non-true value.
See the Sample section for a sample with detailed explanations.
To open a database access handle object (in the new default location):
var db = window.sqlitePlugin.openDatabase({name: 'my.db', location: 'default'}, successcb, errorcb);
WARNING: The new "default" location value is NOT the same as the old default location and would break an upgrade for an app that was using the old default value (0) on iOS.
To specify a different location (affects iOS only):
var db = window.sqlitePlugin.openDatabase({name: 'my.db', iosDatabaseLocation: 'Library'}, successcb, errorcb);
where the iosDatabaseLocation option may be set to one of the following choices:
default: Library/LocalDatabase subdirectory - NOT visible to iTunes and NOT backed up by iCloudLibrary: Library subdirectory - backed up by iCloud, NOT visible to iTunesDocuments: Documents subdirectory - visible to iTunes and backed up by iCloudWARNING: Again, the new "default" iosDatabaseLocation value is NOT the same as the old default location and would break an upgrade for an app using the old default value (0) on iOS.
ALTERNATIVE (deprecated):
var db = window.sqlitePlugin.openDatabase({name: "my.db", location: 1}, successcb, errorcb);with the location option set to one the following choices (affects iOS only):
0 Documents - visible to iTunes and backed up by iCloud1: Library - backed up by iCloud, NOT visible to iTunes2: Library/LocalDatabase - NOT visible to iTunes and NOT backed up by iCloud (same as using "default")No longer supported (see tip below to overwrite window.openDatabase): var db = window.sqlitePlugin.openDatabase("myDatabase.db", "1.0", "Demo", -1);
IMPORTANT: Please wait for the 'deviceready' event, as in the following example:
// Wait for Cordova to load
document.addEventListener('deviceready', onDeviceReady, false);
// Cordova is ready
function onDeviceReady() {
var db = window.sqlitePlugin.openDatabase({name: 'my.db', location: 'default'});
// ...
}
The successcb and errorcb callback parameters are optional but can be extremely helpful in case anything goes wrong. For example:
window.sqlitePlugin.openDatabase({name: 'my.db', location: 'default'}, function(db) {
db.transaction(function(tx) {
// ...
}, function(err) {
console.log('Open database ERROR: ' + JSON.stringify(err));
});
});
If any sql statements or transactions are attempted on a database object before the openDatabase result is known, they will be queued and will be aborted in case the database cannot be opened.
OTHER NOTES:
Web SQL replacement tip:
To overwrite window.openDatabase:
window.openDatabase = function(dbname, ignored1, ignored2, ignored3) {
return window.sqlitePlugin.openDatabase({name: dbname, location: 'default'});
};
As documented in the "A User’s iCloud Storage Is Limited" section of iCloudFundamentals in Mac Developer Library iCloud Design Guide (near the beginning):
- iCloudFundamentals in Mac Developer Library iCloud Design Guide
- DO store the following in iCloud:
- [other items omitted]
- Change log files for a SQLite database (a SQLite database’s store file must never be stored in iCloud)
- DO NOT store the following in iCloud:
- [items omitted]
Use the location or iosDatabaseLocation option in sqlitePlugin.openDatabase() to store the database in a subdirectory that is NOT backed up to iCloud, as described in the section below.
NOTE: Changing BackupWebStorage in config.xml has no effect on a database created by this plugin. BackupWebStorage applies only to local storage and/or Web SQL storage created in the WebView (not using this plugin). For reference: phonegap/build#338 (comment)
By default, this plugin uses Android-sqlite-connector, which is lightweight and should be more efficient than the built-in Android database classes. To use the built-in Android database classes instead:
var db = window.sqlitePlugin.openDatabase({name: 'my.db', location: 'default', androidDatabaseImplementation: 2});
litehelpers/Cordova-sqlite-storage#193 was reported (as observed by a number of app developers) that when using the androidDatabaseImplementation: 2 setting on certain Android versions and if the app is stopped or aborted without closing the database then:
The cause of this issue remains unknown. Of interest: android / platform_external_sqlite commit d4f30d0d15 which references and includes the sqlite commit at: http://www.sqlite.org/src/info/6c4c2b7dba
This is not an issue when the default Android-sqlite-connector database implementation is used, which is the case when no androidDatabaseImplementation setting is used.
There is an optional workaround that simply closes and reopens the database file at the end of every transaction that is committed. The workaround is enabled by opening the database with options as follows:
var db = window.sqlitePlugin.openDatabase({
name: 'my.db',
location: 'default',
androidDatabaseImplementation: 2,
androidLockWorkaround: 1
});
IMPORTANT NOTE: This workaround is only applied when using db.sqlBatch or db.transaction(), not applied when running executeSql() on the database object.
The following types of SQL transactions are supported by this version:
NOTE: Transaction requests are kept in one queue per database and executed in sequential order, according to the HTML5/Web SQL API.
Sample with INSERT:
db.executeSql('INSERT INTO MyTable VALUES (?)', ['test-value'], function (resultSet) {
console.log('resultSet.insertId: ' + resultSet.insertId);
console.log('resultSet.rowsAffected: ' + resultSet.rowsAffected);
}, function(error) {
console.log('SELECT error: ' + error.message);
});
Sample with SELECT:
db.executeSql("SELECT LENGTH('tenletters') AS stringlength", [], function (resultSet) {
console.log('got stringlength: ' + resultSet.rows.item(0).stringlength);
}, function(error) {
console.log('SELECT error: ' + error.message);
});
NOTE/minor bug: The object returned by resultSet.rows.item(rowNumber) is not immutable. In addition, multiple calls to resultSet.rows.item(rowNumber) with the same rowNumber on the same resultSet object return the same object. For example, the following code will show Second uppertext result: ANOTHER:
db.executeSql("SELECT UPPER('First') AS uppertext", [], function (resultSet) {
var obj1 = resultSet.rows.item(0);
obj1.uppertext = 'ANOTHER';
console.log('Second uppertext result: ' + resultSet.rows.item(0).uppertext);
console.log('SELECT error: ' + error.message);
});
Sample:
db.sqlBatch([
'DROP TABLE IF EXISTS MyTable',
'CREATE TABLE MyTable (SampleColumn)',
[ 'INSERT INTO MyTable VALUES (?)', ['test-value'] ],
], function() {
db.executeSql('SELECT * FROM MyTable', [], function (resultSet) {
console.log('Sample column value: ' + resultSet.rows.item(0).SampleColumn);
});
}, function(error) {
console.log('Populate table error: ' + error.message);
});
In case of an error, all changes in a sql batch are automatically discarded using ROLLBACK.
Standard asynchronous transactions follow the HTML5/Web SQL API which is very well documented and uses BEGIN and COMMIT or ROLLBACK to keep the transactions failure-safe. Here is a simple example:
db.transaction(function(tx) {
tx.executeSql('DROP TABLE IF EXISTS MyTable');
tx.executeSql('CREATE TABLE MyTable (SampleColumn)');
tx.executeSql('INSERT INTO MyTable VALUES (?)', ['test-value'], function(tx, resultSet) {
console.log('resultSet.insertId: ' + resultSet.insertId);
console.log('resultSet.rowsAffected: ' + resultSet.rowsAffected);
}, function(tx, error) {
console.log('INSERT error: ' + error.message);
});
}, function(error) {
console.log('transaction error: ' + error.message);
}, function() {
console.log('transaction ok');
});
In case of a read-only transaction, it is possible to use readTransaction which will not use BEGIN, COMMIT, or ROLLBACK:
db.readTransaction(function(tx) {
tx.executeSql("SELECT UPPER('Some US-ASCII text') AS uppertext", [], function(tx, resultSet) {
console.log("resultSet.rows.item(0).uppertext: " + resultSet.rows.item(0).uppertext);
}, function(tx, error) {
console.log('SELECT error: ' + error.message);
});
}, function(error) {
console.log('transaction error: ' + error.message);
}, function() {
console.log('transaction ok');
});
WARNING: It is NOT allowed to execute sql statements on a transaction after it has finished. Here is an example from the Populating Cordova SQLite storage with the JQuery API post at http://www.brodybits.com/cordova/sqlite/api/jquery/2015/10/26/populating-cordova-sqlite-storage-with-the-jquery-api.html:
// BROKEN SAMPLE:
var db = window.sqlitePlugin.openDatabase({name: "test.db"});
db.executeSql("DROP TABLE IF EXISTS tt");
db.executeSql("CREATE TABLE tt (data)");
db.transaction(function(tx) {
$.ajax({
url: 'https://api.github.com/users/litehelpers/repos',
dataType: 'json',
success: function(res) {
console.log('Got AJAX response: ' + JSON.stringify(res));
$.each(res, function(i, item) {
console.log('REPO NAME: ' + item.name);
tx.executeSql("INSERT INTO tt values (?)", JSON.stringify(item.name));
});
}
});
}, function(e) {
console.log('Transaction error: ' + e.message);
}, function() {
// Check results:
db.executeSql('SELECT COUNT(*) FROM tt', [], function(res) {
console.log('Check SELECT result: ' + JSON.stringify(res.rows.item(0)));
});
});
You can find more details and a step-by-step description how to do this right in the Populating Cordova SQLite storage with the JQuery API post at: http://www.brodybits.com/cordova/sqlite/api/jquery/2015/10/26/populating-cordova-sqlite-storage-with-the-jquery-api.html
NOTE/minor bug: Just like the single-statement transaction described above, the object returned by resultSet.rows.item(rowNumber) is not immutable. In addition, multiple calls to resultSet.rows.item(rowNumber) with the same rowNumber on the same resultSet object return the same object. For example, the following code will show Second uppertext result: ANOTHER:
db.readTransaction(function(tx) {
tx.executeSql("SELECT UPPER('First') AS uppertext", [], function(tx, resultSet) {
var obj1 = resultSet.rows.item(0);
obj1.uppertext = 'ANOTHER';
console.log('Second uppertext result: ' + resultSet.rows.item(0).uppertext);
console.log('SELECT error: ' + error.message);
});
});
FUTURE TBD: It should be possible to get a row result object using resultSet.rows[rowNumber], also in case of a single-statement transaction. This is non-standard but is supported by the Chrome desktop browser.
The threading model depends on which version is used:
Creates a table, adds a single entry, then queries the count to check if the item was inserted as expected. Note that a new transaction is created in the middle of the first callback.
// Wait for Cordova to load
document.addEventListener('deviceready', onDeviceReady, false);
// Cordova is ready
function onDeviceReady() {
var db = window.sqlitePlugin.openDatabase({name: 'my.db', location: 'default'});
db.transaction(function(tx) {
tx.executeSql('DROP TABLE IF EXISTS test_table');
tx.executeSql('CREATE TABLE IF NOT EXISTS test_table (id integer primary key, data text, data_num integer)');
// demonstrate PRAGMA:
db.executeSql("pragma table_info (test_table);", [], function(res) {
console.log("PRAGMA res: " + JSON.stringify(res));
});
tx.executeSql("INSERT INTO test_table (data, data_num) VALUES (?,?)", ["test", 100], function(tx, res) {
console.log("insertId: " + res.insertId + " -- probably 1");
console.log("rowsAffected: " + res.rowsAffected + " -- should be 1");
db.transaction(function(tx) {
tx.executeSql("select count(id) as cnt from test_table;", [], function(tx, res) {
console.log("res.rows.length: " + res.rows.length + " -- should be 1");
console.log("res.rows.item(0).cnt: " + res.rows.item(0).cnt + " -- should be 1");
});
});
}, function(e) {
console.log("ERROR: " + e.message);
});
});
}
NOTE: PRAGMA statements must be executed in executeSql() on the database object (i.e. db.executeSql()) and NOT within a transaction.
In this case, the same transaction in the first executeSql() callback is being reused to run executeSql() again.
// Wait for Cordova to load
document.addEventListener('deviceready', onDeviceReady, false);
// Cordova is ready
function onDeviceReady() {
var db = window.sqlitePlugin.openDatabase({name: 'my.db', location: 'default'});
db.transaction(function(tx) {
tx.executeSql('DROP TABLE IF EXISTS test_table');
tx.executeSql('CREATE TABLE IF NOT EXISTS test_table (id integer primary key, data text, data_num integer)');
tx.executeSql("INSERT INTO test_table (data, data_num) VALUES (?,?)", ["test", 100], function(tx, res) {
console.log("insertId: " + res.insertId + " -- probably 1");
console.log("rowsAffected: " + res.rowsAffected + " -- should be 1");
tx.executeSql("select count(id) as cnt from test_table;", [], function(tx, res) {
console.log("res.rows.length: " + res.rows.length + " -- should be 1");
console.log("res.rows.item(0).cnt: " + res.rows.item(0).cnt + " -- should be 1");
});
}, function(tx, e) {
console.log("ERROR: " + e.message);
});
});
}
This case will also works with Safari (WebKit), assuming you replace window.sqlitePlugin.openDatabase with window.openDatabase.
This will invalidate all handle access handle objects for the database that is closed:
db.close(successcb, errorcb);
It is OK to close the database within a transaction callback but NOT within a statement callback. The following example is OK:
db.transaction(function(tx) {
tx.executeSql("SELECT LENGTH('tenletters') AS stringlength", [], function(tx, res) {
console.log('got stringlength: ' + res.rows.item(0).stringlength);
});
}, function(error) {
// OK to close here:
console.log('transaction error: ' + error.message);
db.close();
}, function() {
// OK to close here:
console.log('transaction ok');
db.close(function() {
console.log('database is closed ok');
});
});
The following example is NOT OK:
// BROKEN:
db.transaction(function(tx) {
tx.executeSql("SELECT LENGTH('tenletters') AS stringlength", [], function(tx, res) {
console.log('got stringlength: ' + res.rows.item(0).stringlength);
// BROKEN - this will trigger the error callback:
db.close(function() {
console.log('database is closed ok');
}, function(error) {
console.log('ERROR closing database');
});
});
});
BUG: It is currently NOT possible to close a database in a db.executeSql callback. For example:
// BROKEN DUE TO BUG:
db.executeSql("SELECT LENGTH('tenletters') AS stringlength", [], function (res) {
var stringlength = res.rows.item(0).stringlength;
console.log('got stringlength: ' + res.rows.item(0).stringlength);
// BROKEN - this will trigger the error callback DUE TO BUG:
db.close(function() {
console.log('database is closed ok');
}, function(error) {
console.log('ERROR closing database');
});
});
SECOND BUG: When a database connection is closed, any queued transactions are left hanging. All pending transactions should be errored when a database connection is closed.
NOTE: As described above, if multiple database access handle objects are opened for the same database and one database handle access object is closed, the database is no longer available for the other database handle objects. Possible workarounds:
FUTURE TBD: dispose method on the database access handle object, such that a database is closed once all access handle objects are disposed.
window.sqlitePlugin.deleteDatabase({name: 'my.db', location: 'default'}, successcb, errorcb);
with location or iosDatabaseLocation parameter required as described above for openDatabase (affects iOS only)
BUG: When a database is deleted, any queued transactions for that database are left hanging. All pending transactions should be errored when a database is deleted.
The transactional nature of the API makes it relatively straightforward to manage a database schema that may be upgraded over time (adding new columns or new tables, for example). Here is the recommended procedure to follow upon app startup:
db.executeSql since it should be a very simple query)sqlite_master table as described at: http://stackoverflow.com/questions/1601151/how-do-i-check-in-sqlite-whether-a-table-exists)IMPORTANT: Since we cannot be certain when the users will actually update their apps, old schema versions will have to be supported for a very long time.
It is recommended to follow the tutorial (with some adaptations) at: https://blog.nraboy.com/2014/11/use-sqlite-instead-local-storage-ionic-framework/

cordova-sqlite-storage - stable npm package versionUse window.sqlitePlugin.echoTest and/or window.sqlitePlugin.selfTest as described above (please wait for the deviceready event).
Assuming your app has a recent template as used by the Cordova create script, add the following code to the onDeviceReady function, after app.receivedEvent('deviceready');:
window.sqlitePlugin.openDatabase({ name: 'hello-world.db', location: 'default' }, function (db) {
db.executeSql("select length('tenletters') as stringlength", [], function (res) {

Free support is provided on a best-effort basis and is only available in public forums. Please follow the steps below to be sure you have done your best before requesting help. Use with Ionic and other Angular derivatives is no longer covered by free support.
Professional support is available by contacting: sales@litehelpers.net
For more information: http://litehelpers.net/
First steps:
and check the following:
cordova.js.config.xml.If you still cannot get something to work:
General: As documented above with a negative example the application must wait for the AJAX query to finish before starting a transaction and adding the data elements.
In case of issues it is recommended to rework the reproduction program insert the data from a JavaScript object after a delay. There is already a test function for this in brodybits / Cordova-sqlite-bootstrap-test.
FUTURE TBD examples
If you continue to see the issue: please make the simplest test program possible based on brodybits / Cordova-sqlite-bootstrap-test to demonstrate the issue with the following characteristics:
It is recommended to make a small, self-contained test program based on brodybits / Cordova-sqlite-bootstrap-test that can demonstrate your problem and post it. Please do not use any other plugins or frameworks than are absolutely necessary to demonstrate your problem.
In case of a problem with a pre-populated database, please post your entire project.
Professional support is available for use with Ionic and other forms of ngCordova/Angular. For more information please contact: sales@litehelpers.net

Unit testing is done in spec.
To run the tests from *nix shell, simply do either:
./bin/test.sh ios
or for Android:
./bin/test.sh android
To run from a windows powershell (here is a sample for android target):
.\bin\test.ps1 android
Please look at the Lawnchair-adapter tree that contains a common adapter, which should also work with the Android version, along with a test-www directory.
Include the following Javascript files in your HTML:
cordova.js (don't forget!)lawnchair.js (you provide)SQLitePlugin.js (in case of Cordova pre-3.0)Lawnchair-sqlitePlugin.js (must come after SQLitePlugin.js in case of Cordova pre-3.0)The name option determines the sqlite database filename, with no extension automatically added. Optionally, you can change the db filename using the db option.
In this example, you would be using/creating a database with filename kvstore:
kvstore = new Lawnchair({name: "kvstore"}, function() {

);
Using the db option you can specify the filename with the desired extension and be able to create multiple stores in the same database file. (There will be one table per store.)
recipes = new Lawnchair({db: "cookbook", name: "recipes", ...}, myCallback());
ingredients = new Lawnchair({db: "cookbook", name: "ingredients", ...}, myCallback());
KNOWN ISSUE: Not all db options are supported by the Lawnchair adapter. The workaround is to first open the database file using sqlitePlugin.openDatabase().
The adapter is part of PouchDB as documented at:
The PouchDB authors maintain their own sqlite plugin. TBD a comparison will be given soon.

The SQLite storage plugin sample allows you to execute SQL statements to interact with the database. The code snippets in this section demonstrate simple plugin tasks including:
##Open the database and create a table
Call the openDatabase() function to get started, passing in the name and location for the database.
var db = window.sqlitePlugin.openDatabase({ name: 'my.db', location: 'default' }, function (db) {
// Here, you might create or open the table.
}, function (error) {
console.log('Open database ERROR: ' + JSON.stringify(error));
});
Create a table with three columns for first name, last name, and a customer account number. If the table already exists, this SQL statement opens the table.
db.transaction(function (tx) {
// ...
tx.executeSql('CREATE TABLE customerAccounts (firstname, lastname, acctNo)');
}, function (error) {
console.log('transaction error: ' + error.message);
}, function () {
console.log('transaction ok');
});
By wrapping the previous executeSql() function call in db.transaction(), we will make these tasks asynchronous. If you want to, you can use multiple executeSql() statements within a single transaction (not shown).
Add a row to the database using the INSERT INTO SQL statement.
function addItem(first, last, acctNum) {
db.transaction(function (tx) {
var query = "INSERT INTO customerAccounts (firstname, lastname, acctNo) VALUES (?,?,?)";
tx.executeSql(query, [first, last, acctNum], function(tx, res) {
console.log("insertId: " + res.insertId + " -- probably 1");
console.log("rowsAffected: " + res.rowsAffected + " -- should be 1");
},
function(tx, error) {
console.log('INSERT error: ' + error.message);
});
}, function(error) {
console.log('transaction error: ' + error.message);
}, function() {
console.log('transaction ok');
});
}
To add some actual rows in your app, call the addItem function several times.
addItem("Fred", "Smith", 100);
addItem("Bob", "Yerunkle", 101);
addItem("Joe", "Auzomme", 102);
addItem("Pete", "Smith", 103);
Add code to read from the database using a SELECT statement. Include a WHERE condition to match the resultSet to the passed in last name.
function getData(last) {
db.transaction(function (tx) {
var query = "SELECT firstname, lastname, acctNo FROM customerAccounts WHERE lastname = ?";
tx.executeSql(query, [last], function (tx, resultSet) {
for(var x = 0; x < resultSet.rows.length; x++) {
console.log("First name: " + resultSet.rows.item(x).firstname +
", Acct: " + resultSet.rows.item(x).acctNo);
}
},
function (tx, error) {
console.log('SELECT error: ' + error.message);
});
}, function (error) {
console.log('transaction error: ' + error.message);
}, function () {
console.log('transaction ok');
});
}
##Remove a row from the database
Add a function to remove a row from the database that matches the passed in customer account number.
function removeItem(acctNum) {
db.transaction(function (tx) {
var query = "DELETE FROM customerAccounts WHERE acctNo = ?";
tx.executeSql(query, [acctNum], function (tx, res) {
console.log("removeId: " + res.insertId);
console.log("rowsAffected: " + res.rowsAffected);
},
function (tx, error) {
console.log('DELETE error: ' + error.message);
});
}, function (error) {
console.log('transaction error: ' + error.message);
}, function () {
console.log('transaction ok');
});
}
Add a function to update rows in the database for records that match the passed in customer account number. In this form, the statement will update multiple rows if the account numbers are not unique.
function updateItem(first, id) {
// UPDATE Cars SET Name='Skoda Octavia' WHERE Id=3;
db.transaction(function (tx) {
var query = "UPDATE customerAccounts SET firstname = ? WHERE acctNo = ?";
tx.executeSql(query, [first, id], function(tx, res) {
console.log("insertId: " + res.insertId);
console.log("rowsAffected: " + res.rowsAffected);
},
function(tx, error) {
console.log('UPDATE error: ' + error.message);
});
}, function(error) {
console.log('transaction error: ' + error.message);
}, function() {
console.log('transaction ok');
});
}
To call the preceding function, add code like this in your app.
updateItem("Yme", 102);
When you are finished with your transactions, close the database. Call closeDB within the transaction success or failure callbacks (rather than the callbacks for executeSql()).
function closeDB() {
db.close(function () {
console.log("DB closed!");
}, function (error) {
console.log("Error closing DB:" + error.message);
});
