PDO::lastInsertId
(PHP 5 >= 5.1.0, PECL pdo:0.1-1.0.3)
PDO::lastInsertId — Returns the ID of the last inserted row or sequence value
Description
Returns the ID of the last inserted row, or the last value from a sequence object, depending on the underlying driver. For example, PDO_PGSQL() requires you to specify the name of a sequence object for the name parameter.
Note: This method may not return a meaningful or consistent result across different PDO drivers, because the underlying database may not even support the notion of auto-increment fields or sequences.
Parameters
- name
-
Name of the sequence object from which the ID should be returned.
Return Values
If a sequence name was not specified for the name parameter, PDO::lastInsertId() returns a string representing the row ID of the last row that was inserted into the database.
If a sequence name was specified for the name parameter, PDO::lastInsertId() returns a string representing the last value retrieved from the specified sequence object.
If the PDO driver does not support this capability, PDO::lastInsertId() triggers an IM001 SQLSTATE.
