db\Command createTable()

createTable() public method

Creates a SQL command for creating a new DB table.

The columns in the new table should be specified as name-definition pairs (e.g. 'name' => 'string'), where name stands for a column name which will be properly quoted by the method, and definition stands for the column type which can contain an abstract DB type. The method yii\db\QueryBuilder::getColumnType() will be called to convert the abstract column types to physical ones. For example, string will be converted as varchar(255), and string not null becomes varchar(255) not null.

If a column is specified with definition only (e.g. 'PRIMARY KEY (name, type)'), it will be directly inserted into the generated SQL.

public $this createTable ( $table, $columns, $options = null )
$table string

The name of the table to be created. The name will be properly quoted by the method.

$columns array

The columns (name => definition) in the new table.

$options string

Additional SQL fragment that will be appended to the generated SQL.

return $this

The command object itself
