NodeJS SQL query builder

Build Status

Install

npm install sql-query --save

Dialects

  • MySQL
  • PostgreSQL
  • SQLite
  • MSSQL

About

This module is used by ORM to build SQL queries in the different supported dialects. Sorry the API documentation is not complete. There are tests in ./test/integration that you can read.

Usage

var sql = require('sql-query'),
  sqlQuery = sql.Query();

Create

var sqlCreate = sqlQuery.create();

sqlCreate
  .table('table1')
  .build()

"CREATE TABLE 'table1'()"


sqlCreate
  .table('table1')
  .field('id','id')
  .build()

"CREATE TABLE 'table1'('id' INTEGER PRIMARY KEY AUTO_INCREMENT)"


sqlCreate
  .table('table1')
  .fields({id: 'id', a_text: 'text'})
  .build()

"CREATE TABLE 'table1'('id' INTEGER PRIMARY KEY AUTO_INCREMENT,'a_text' TEXT)"


sqlCreate
  .table('table1')
  .fields({id: 'id', a_num: 'int'})
  .build()

"CREATE TABLE 'table1'('id' INTEGER PRIMARY KEY AUTO_INCREMENT,'a_num' INTEGER)"


sqlCreate
  .table('table1')
  .fields({id: 'id', a_num: 'float'})
  .build()

"CREATE TABLE 'table1'('id' INTEGER PRIMARY KEY AUTO_INCREMENT,'a_num' FLOAT(12,2))"


sqlCreate
  .table('table1')
  .fields({id: 'id', a_bool: 'bool'})
  .build()

"CREATE TABLE 'table1'('id' INTEGER PRIMARY KEY AUTO_INCREMENT,'a_bool' TINYINT(1))"

Select

var sqlSelect = sqlQuery.select();

sqlSelect
  .from('table1')
  .build();

"SELECT * FROM `table1`"


sqlSelect
  .from('table1')
  .select('id', 'name')
