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(); //for dialect: sql.Query('postgresql')
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))"
