CzProject\SqlGenerator

Installation

Download a latest package or use Composer:

composer require czproject/sql-generator

CzProject\SqlGenerator requires PHP 8.0 or later.

Usage

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:

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:

$sql->createTable($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:

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

Check if is SQL document empty:

$sql->isEmpty();

Generate SQL:

$sql->toSql($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.

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.

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.
