SQLite Porter Cordova/Phonegap Plugin

This Cordova/Phonegap plugin can be used to import/export to/from a SQLite database using either SQL or JSON.

  • Works on all Cordova platforms that support HTML5 WebSQL DB in the WebView:
    • Android
    • iOS
    • Tizen
    • Blackberry 10
  • Works for native SQLite DB via a plugin. This can be used for platforms that don't have WebSQL in WebView (e.g. Windows) or for unlimited storage on platforms that do:
    • Android
    • iOS
    • Amazon Fire-OS
    • Windows Universal (8.1)
    • Windows Phone 7
    • Windows Phone 8
  • Import/export either just the table data or the entire table structure as well.

Usage scenarios

  • Create and populate a database from a database dump.
  • Update an existing database by importing inserts/updates/deletes.
  • Export and send data from a database.

Contents

Installation

Using the Cordova/Phonegap CLI

$ cordova plugin add uk.co.workingedge.cordova.plugin.sqliteporter
$ phonegap plugin add uk.co.workingedge.cordova.plugin.sqliteporter

Using Cordova Plugman

$ plugman install --plugin=uk.co.workingedge.cordova.plugin.sqliteporter --platform=<platform> --project=<project_path> --plugins_dir=plugins

For example, to install for the Android platform

$ plugman install --plugin=uk.co.workingedge.cordova.plugin.sqliteporter --platform=android --project=platforms/android --plugins_dir=plugins

PhoneGap Build

Add the following xml to your config.xml to use the latest version of this plugin from plugins.cordova.io:

<gap:plugin name="uk.co.workingedge.cordova.plugin.sqliteporter" source="plugins.cordova.io" />

or from npmjs.com:

<gap:plugin name="uk.co.workingedge.cordova.plugin.sqliteporter" source="npm" />

Usage

The plugin is exposed via the cordova.plugins.sqlitePorter object and provides the following functions:

importSqlToDb()

Executes a set of SQL statements against the defined database. Can be used to import data defined in the SQL statements into the database, and may additionally include commands to create the table structure.

cordova.plugins.sqlitePorter.importSqlToDb(db, sql, opts);

Parameters

  • {Database} db - open SQLite database to import into
  • {string} sql - SQL statements to execute against database.
  • {object} opts - optional parameters:
    • {function} successFn - callback function to execute once import is complete, called with arguments:
      • {integer} count - total number of statements executed in the given SQL string.
    • {function} errorFn - callback function to execute on error during import, called with arguments:
      • {object} error - object representing the error.
    • {function} progressFn - callback function to execute after each successful execution of SQL statement, called with arguments:
      • {object} count - number of statements executed so far.
      • {integer} totalCount - total number of statements in the given SQL string.

Example usage

Create a database from a SQL dump

var db = window.openDatabase("Test", "1.0", "TestDB", 1 * 1024);
var sql = "CREATE TABLE Artist ([Id] PRIMARY KEY, [Title]);"+
    "INSERT INTO Artist(Id,Title) VALUES ('1','Fred');";
var successFn = function(count){
    alert("Successfully imported "+count+" SQL statements to DB");
};
var errorFn = function(error){
    alert("The following error occurred: "+error.message);
};
var progressFn = function(current, total){
    console.log("Imported "+current+"/"+total+" statements";
};
cordova.plugins.sqlitePorter.importSqlToDb(db, sql, {
    successFn: successFn,
    errorFn: errorFn,
    progressFn: progressFn
});

Update an existing database

var db = window.openDatabase("Test", "1.0", "TestDB", 1 * 1024);
var sql = "INSERT INTO Artist(Id,Title) VALUES ('6','Jane');"+
    "UPDATE Artist SET Title='Susan' WHERE Id='2';"+
    "DELETE FROM Artist WHERE Id='5';";
var successFn = function(count){
    alert("Successfully imported "+count+" SQL statements to DB");
};
var errorFn = function(error){
    alert("The following error occurred: "+error.message);
};
var progressFn = function(current, total){
    console.log("Imported "+current+"/"+total+" statements";
};
cordova.plugins.sqlitePorter.importSqlToDb(db, sql, {
    successFn: successFn,
    errorFn: errorFn,
    progressFn: progressFn
});

exportDbToSql()

Exports a SQLite DB as a set of SQL statements.

cordova.plugins.sqlitePorter.exportDbToSql(db, opts);

Parameters
