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 ( $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.

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;
        }
    }
}
