(no version information, might be only in CVS)PDO::lastInsertId -- Returns the ID of the last inserted row or sequence value
Returns the ID of the last inserted row, or the last value from a sequence object, depending on the underlying driver.
Nota: This method may not return a meaningful/consistent result across different PDO drivers, because the underlying database may not even support the notion of auto-increment fields or sequences.
If a sequence name was not specified for the name parameter, PDOStatement::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, PDOStatement::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.
