## Installation

[Download a latest package](https://github.com/czproject/sql-generator/releases) or use [Composer](http://getcomposer.org/):

```

composer require czproject/sql-generator

```

`CzProject\SqlGenerator` requires PHP 5.6.0 or later.

## Usage

``` php

use CzProject\SqlGenerator\Drivers;

use CzProject\SqlGenerator\SqlDocument;

$sql = new SqlDocument;

$driver = new Drivers\MysqlDriver;

$contactTable = $sql->createTable('contact')

	->setComment('Clients table.')

	->setOption('ENGINE', 'InnoDB');

$contactTable->addColumn('id', 'INT', NULL, array('UNSIGNED' => NULL))

	->setAutoIncrement();

$contactTable->addColumn('name', 'VARCHAR(100)')

	->setComment('Client name');

$contactTable->addColumn('surname', 'VARCHAR(100)');

$contactTable->addColumn('active', 'unsigned TINYINT')

	->setDefaultValue(TRUE);

$contactTable->addColumn('created', 'DATETIME');

$contactTable->addColumn('removed', 'DATETIME')

	->setNullable();

$contactTable->addIndex(NULL, IndexDefinition::TYPE_PRIMARY)

	->addColumn('id');

$contactTable->addIndex('name_surname', IndexDefinition::TYPE_UNIQUE)

	->addColumn('name', 'ASC', 100)

	->addColumn('surname', 'DESC', 100);

$output = $sql->toSql($driver);

```

Outputs:

``` sql

CREATE TABLE `contact` (

	`id` INT UNSIGNED NOT NULL AUTO_INCREMENT,

	`name` VARCHAR(100) NOT NULL COMMENT 'Client name',

	`surname` VARCHAR(100) NOT NULL,

	`active` TINYINT(1) UNSIGNED NOT NULL DEFAULT 1,

	`created` DATETIME NOT NULL,

	`removed` DATETIME NULL,

	PRIMARY KEY (`id`),

	UNIQUE KEY `name_surname` (`name` (100), `surname` (100) DESC)

)

COMMENT 'Clients table.'

ENGINE=InnoDB;

```

## Statements

There is few predefined statements:

```php

$sql->createTable($tableName);

$sql->dropTable($tableName);

$sql->renameTable($old, $new);

$sql->alterTable($tableName);

$sql->insert($tableName, $data);

$sql->command($command); // for example $sql->command('SET NAMES "utf8"');

$sql->comment($comment);

```

You can add custom statements:

```php

$sql->addStatement(new Statements\CreateTable($tableName));

```

Check if is SQL document empty:

```php

$sql->isEmpty();

```

Generate SQL:

```php

$sql->toSql($driver); // returns string

$sql->getSqlQueries($driver); // returns string[]

$sql->save($file, $driver); // saves SQL into file

```

## Special Values

There are value objects for specific cases:

### TableName

Delimited table name.

```php

use CzProject\SqlGenerator\TableName;

$table = $sql->createTable(TableName::create('schema.table'))

$table->addForeignKey('fk_table_id', 'id', TableName::create('schema2.table2'), 'id');

// and more ($sql->renameTable(),...)

```

### Value

Scalar/stringable/datetime value. It can be used in option values.

```php

use CzProject\SqlGenerator\Value;

$table->setOption('AUTO_INCREMENT', Value::create(123)); // generates AUTO_INCREMENT=123

$table->setOption('CHECKSUM', Value::create(FALSE)); // generates CHECKSUM=0

$table->setOption('COMPRESSION', Value::create('NONE')); // generates COMPRESSION='NONE'

```

## Supported database

Currently is supported common SQL and MySQL.
