Node.js Database Query String Builder (QSB) for Mysql/MariaDB
Forked from node-qsb
Added functions : whereIn, whereNotIn, leftJoin, rightJoin
- Insert or update 'NULL' data
- support join ON clause
- can add sub-query in 'FROM, JOIN'
Summary
- node-qsb is very simple Database Query String Builder. create String object only.
- It is independent of the Database driver module.
Available DBMS
- MySQL, MariaDB
Installation
Example
SELECT Query
Default
var qsb = require('node-qsb');
var qs = new qsb().select('tableName').where('idx', '>', '10').build();
qs.printString(); //SELECT * FROM `tableName` WHERE `idx` > '10';
console.log(qs.returnString()); //SELECT * FROM `tableName` WHERE `idx` > '10';
qs.where('name', '=', 'Yowu').build();
console.log(qs.returnString());
//SELECT * FROM `tableName` WHERE `idx` > '10' AND `name` = 'Yowu';
qs.whereOr('name', '=', 'Yu Yongwoo').build();
console.log(qs.returnString());
//SELECT * FROM `tableName` WHERE `idx` > '10' AND `name` = 'Yowu' OR `name` = 'Yu Yongwoo';
Not Using 'Select *'
var qsb = require('node-qsb');
var qs = new qsb().select('tableName').get('col1').get('col2').build();
console.log(qs.returnString());
//SELECT `col1`, `col2` FROM `tableName`;
JOIN, LIMIT, ORDER BY
var qsb = require('node-qsb');
var qs = new qsb().select('tableName', 'TN1')
.join('tableName2', 'TN2')
.where('TN1.idx', '<=', 1
.whereOr('TN2.idx', '=', 'TN1.idx')
.build().printString();
//SELECT * FROM `tableName` `TN1` JOIN `tableName2` `TN2` WHERE `TN1`.`idx` <= '10' OR `TN2`.`idx` = 'TN1.idx';
qs.limit(0, 10).build();
console.log(qs.returnString());
//SELECT * FROM `tableName` `TN1` JOIN `tableName2` `TN2` WHERE `TN1`.`idx` <= '10' OR `TN2`.`idx` = 'TN1.idx' LIMIT '0', '10';
qs.orderBy('TN1.idx', 'desc').build();
console.log(qs.returnString());
//SELECT * FROM `tableName` `TN1` JOIN `tableName2` `TN2` WHERE `TN1`.`idx` <= '10' OR `TN2`.`idx` = 'TN1.idx' ORDER BY `TN1`.`idx` desc LIMIT '0', '10';
INSERT Query
var qsb = require('node-qsb');
var qs1 = new qsb().insert('tableName')
.values(['colName'], ['Value'])
.build().printString();
//INSERT INTO `tableName`(`colName`) VALUES ('value');
var params = {
cols : ['col1', 'col2', 'col3', 'col4'],
vals : ['val1', 'val2', 'val3', 4000],
}
var qs2 = new qsb().insert('tableName')
.values(params.cols, params.vals)
.build().printString();
//INSERT INTO `tableName`(`col1`, `col2`, `col3`, `col4`) VALUES ('val1', 'val2', 'val3', '4000');
qs2.addValues(params.vals).build().printString();
//INSERT INTO `tableName`(`col1`, `col2`, `col3`, `col4`) VALUES ('val1', 'val2', 'val3', '4000'),('val1', 'val2', 'val3', '4000');
UPDATE Query
var qsb = require('node-qsb');
var qs = new qsb().update('tableName')
.set('name', 'Yowu')
.where('idx', '=', '423')
.build().printString();
//UPDATE `tableName` SET `name` = 'Yowu' WHERE `idx` = '423';
qs.set('email', '[email protected]').build().printString();
//UPDATE `tableName` SET `name` = 'Yowu', `email` = '[email protected]' WHERE `idx` = '423';
DELETE Query
var qsb = require('node-qsb');
var qs = new qsb().delete('tableName')
.where('idx', '=', 10)
.build()
.printString();
//DELETE FROM `tableName` WHERE `idx` = '10';
Make Query by Force Input
var qsb = require('node-qsb');
var qs = new qsb().forceQuery('select * from tableName').printString();
//select * from tableName
