SQL Query builder working with NodeJS
npm install mysql-qbuilder --save --save-exat
To add this npm package to your local machine, type the above into your command line. You will notice a node_modules directory appear in your root where the package is now installed.
mysql-qbuilder is NodeJS module provides a convenient, fluent interface to creating and running database queries. It can be used to perform most database operations in your application.
mysql-qbuilder query builder uses mysql module to protect your application against SQL injection attacks. There is no need to clean strings being passed as bindings.
Before to start to used the mysql-qbuilder is need to set some options In this section is show What You need for to work with mysql-qbuilder
const qBuilder = require('mysql-qbuilder')
qBuilder.setOptions({
hostname: 'hostName',
username: 'userName',
password: 'passWord',
database: 'databaseName'
})
qBuilder.connectToDatabase()
qBuilder.makeQuery()
sql query clausesSELECTSELECT ADDINSERTDELETEUPDATEORDER BYGROUP BYOFFSETLIMITWHEREWHERE ANDWHERE ORWHERE AND ORWHERE NOTWHERE COLUMNWHERE DATEWHERE YEARWHERE MONTHWHERE DAYWHERE INWHERE NOT INWHERE BETWEENWHERE NOT BETWEENWHERE NULLWHERE NOT NULLJOINFROMTABLEselect() addSelect()Some times You don't want to select all columns from database Then You need to enter just the columns. If You want just write *
qBuilder.makeQuery().select('id, title, count')
qBuilder.makeQuery().select(['id', 'title', 'count'])
qBuilder.makeQuery().select('*')
If You forget some column then You can add that columns with addSelect function If You forget some column then You can add that columns with addSelect function
qBuilder.makeQuery()
.select('id, title, count') // Oops I forgot the name column
.addSelect('name') // Alright I added now
.from('tableName') // set Database table
qBuilder.prepare().getResult() // New version bigger of 1.5.1
.then(result => {
})
.catch(err => {
})
qBuilder.prepare().getResult((err, data) => { // Old version less of 1.5.1
// data is the array of objects or just single object
})
add()Many times You don't want to get the data from database. Just want to add new record
qBuilder.makeQuery()
.table('tableName')
.add(['count', 'title', 'name']) // set the column name on database
qBuilder.prepare()
.setParameters([5, 'SomeTitle', 'SomeName']) // set the values of new record
.execute() // Save the new record on database
from() table()The from and table method is just set the table of query
qBuilder.makeQuery()
.select('id, title, count') // Oops I forgot the name column
.from('tableName') // set Database table
qBuilder.prepare().getResult() // New version bigger of 1.5.1
.then(result => {
})
.catch(err => {
})
qBuilder.prepare().getResult((err, data) => { // Old version less of 1.5.1
// data is the array of objects or just single object
})
delete()The query builder may also be used to delete records from the table used delete function
qBuilder.makeQuery()
.table('tableName')
.delete()
.where('id', '=', 10)
qBuilder.prepare().execute()
update()Some times You don't want to select or add new columns or delete Some times is need just update the existing record in database. This is possible with update function
qBuilder.makeQuery()
.table('tableName')
.update(['title', 'count', 'name'])
.where('id', '=')
qBuilder.prepare()
.setParameters(['newTitle', 25, 'newName', 10]) // The last parameter is for where clause
.execute()
addOrUpdate()In some cases You need to add few new records on database, but some times that records is possible to get from database and need just to update if is exists on database
CREATE UNIQUE INDEX title_name_index ON tableName (title, name)qBuilder.makeQuery()
.table('tableName')
// First parameter is for try to add the elements
// Second parameters is for if is exists with same title and name then just update the count
.addOrUpdate(['title', 'count', 'name'], ['count'])
qBuilder.prepare()
.setParameters(['newTitle', 25, 'newName', 25]) // Set the parameters
.execute()
join()With Join is possible to get from database record from two tables with one query.
qBuilder.makeQuery()
.select('tableName.title, anotherTable.name')
.from('tableName') // set Database table
.join('anotherTable', 'tableName.anotherTableId = anotherTable.id', 'Inner')
.where('tableName.id' '>' 2)
qBuilder.prepare().getResult() // New version bigger of 1.5.1
.then(result => {
})
.catch(err => {
})
qBuilder.prepare().getResult((err, data) => { // Old version less of 1.5.1
// data is the array of objects or just single object
})
orderBy()Is A method which You can order by some column
qBuilder.makeQuery()
.select('title, count, name')
.from('tableName') // set Database table

Is possible to used when You want to add new record on database
// Build the query from all simple parts
qBuilder.prepare()
// Set all parameters which You need to used on mysql query builder
.setParameters([param1, param2, param3])
// Just execute the query and don't return some result
.execute()

From v1.3.1 Is possible to used mysql-qbuilder much easier for some common cases like
Add new record on database
qBuilder.useScheme('tableName')
// First field is Object where the keys is column of database and values is the values of columns
.add({ 'username': 'administrator', 'email': 'administrator@admin.com' })
qBuilder.execute()
Get first record from table
qBuilder.useScheme() // used same table like before
// First field is String or Array with all columns which You want to get from database
.getFirst('email, username')
qBuilder.getResult() // New version bigger of 1.5.1
.then(result => {
})
.catch(err => {
})
qBuilder.getResult((err, data) => { // Old version less of 1.5.1
if (err) {
console.log(err)
} else {
// make something with data which is result of mysql query execution
}
})
Get last record from table
qBuilder.useScheme() // used same table like before
// First field is String or Array with all columns which You want to get from database
.getLast('email, username')
qBuilder.getResult() // New version bigger of 1.5.1
.then(result => {
})
.catch(err => {
})
qBuilder.getResult((err, data) => { // Old version less of 1.5.1
if (err) {
console.log(err)
} else {
// make something with data which is result of mysql query execution
}
})
Get all records from table
qBuilder.useScheme() // used same table like before
// First field is String or Array with all columns which You want to get from database
.getAll('email, username')
qBuilder.getResult() // New version bigger of 1.5.1
.then(result => {
})
.catch(err => {
})
qBuilder.getResult((err, data) => { // Old version less of 1.5.1
if (err) {
console.log(err)
} else {
// make something with data which is result of mysql query execution
}
})
Find record on database by entered id
qBuilder.useScheme('tableName')
// First field is id of the record
// Second is all columns which You want to get from database
.findById(2, 'email')
// OR
.findById([2, 3, 4], 'email') // Is find records with id 2, 3 or 4
qBuilder.getResult() // New version bigger of 1.5.1
.then(result => {
})
.catch(err => {
})
qBuilder.getResult((err, data) => { // Old version less of 1.5.1
if (err) {
console.log(err)
} else {
// make something with data which is result of mysql query execution
}
})
Find records on database by many search conditions or (only one)
qBuilder.useScheme('tableName')
// First field is Object where the keys is column of database and values is the values of columns
// Second is all columns which You want to get from database
// Third is do You want every condition to be true or only one
.findByFields({ 'id': 2, 'username': 'administrator' }, 'email', 'or')
// Or Get all records which is with id 2, 3 or 4 or have username administrator or userNaMe
.findByFields({ 'id': [2, 3, 4], 'username': ['administrator', 'userNaMe'] }, 'email', 'or')
qBuilder.getResult() // New version bigger of 1.5.1
.then(result => {
})
.catch(err => {
})
qBuilder.getResult((err, data) => { // Old version less of 1.5.1
if (err) {
console.log(err)
} else {
// make something with data which is result of mysql query execution
}
})
