## Description

string PDO::lastInsertId ( [string name] )

Advarsel
Denne funktion er EKSPERIMENTABEL. Virkemåden af denne funktion, navnet på funktionen, og andet ellers dokumenteret om denne funktion, ændres muligvis uden advarsel i en fremtidig version af PHP. Brug af denne funktion er på ejet ansvar.

Returns the ID of the last inserted row, or the last value from a sequence object, depending on the underlying driver.

> Bemærk: 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.

## Parameterliste

name

  Name of the sequence object from which the ID should be returned.

## Returneringsværdier

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.
