|
* SQLSRV driver implements [[PDO::lastInsertId()]] method but with a single peculiarity:
|
||
|
|
* when `$sequence` value is a null or an empty string it returns an empty string.
|
||
|
|
* But when parameter is not specified it works as expected and returns actual
|
||
|
|
* last inserted ID (like the other PDO drivers).

* @param string|null $sequence the sequence name. Defaults to null.
|
||
|
|
* @return integer last inserted ID value.
