Node.js Database Query String Builder (QSB) for Mysql/MariaDB

# Summary

* node-qsb is very simple Database Query String Builder. create String object only. 

* It is independent of the Database driver module.

* Introduce Article : http://luckyyowu.tistory.com/345 (Korean)

# Available DBMS

* MySQL, MariaDB

# Installation

npm install node-qsb


# Example

## SELECT Query

### Default

```javascript

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 *'

```javascript

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

```javascript

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

```javascript

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

```javascript

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

```javascript

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

```javascript

var qsb = require('node-qsb');

var qs = new qsb().forceQuery('select * from tableName').printString();

//select * from tableName

```
