Method Details

Hide inherited methods

getAttribute() public method

Retrieve a database connection attribute.

It is necessary to override PDO's method as some MSSQL PDO driver (e.g. dblib) does not support getting attributes.

public mixed getAttribute ( integer $attribute )
$attribute	integer	One of the PDO::ATTR_* constants.
return	mixed	A successful call returns the value of the requested PDO attribute. An unsuccessful call returns null.

Source code

 #[\ReturnTypeWillChange] public function getAttribute($attribute) { try { return parent::getAttribute($attribute); } catch (\PDOException $e) { switch ($attribute) { case self::ATTR_SERVER_VERSION: return $this->query("SELECT CAST(SERVERPROPERTY('productversion') AS VARCHAR)")->fetchColumn(); default: throw $e; } } }

lastInsertId() public method

Returns value of the last inserted ID.

public string\|false lastInsertId ( string\|null $name = null )
$name	string\|null	The sequence name. Defaults to null.
return	string\|false	Last inserted ID value.

Source code

 #[\ReturnTypeWillChange] public function lastInsertId($name = null) { return $this->query('SELECT CAST(COALESCE(SCOPE_IDENTITY(), @@IDENTITY) AS bigint)')->fetchColumn(); }
