PDO::lastInsertId
(PHP 5 >= 5.1.0, PHP 7, PHP 8, PECL pdo >= 0.1.0)
PDO::lastInsertId — Returns the ID of the last inserted row or sequence value
Beschreibung
$name = null): string|false
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.
Hinweis:
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.
Parameter-Liste
-
name -
Name of the sequence object from which the ID should be returned.
Rückgabewerte
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.
