PHP-Handbuch: Return the ID generated for the last updated AUTO

Beschreibung

string cubrid_insert_id ([ resource $conn_identifier ] )

The cubrid_insert_id function retrieves the ID generated for the AUTO_INCREMENT column which is updated by the previous INSERT query. It returns 0 if the previous query does not generate new rows, or FALSE on failure.

Hinweis:
CUBRID supports AUTO_INCREMENT for more than one columns in a table. In most cases, there will be a single AUTO_INCREMENT column in a table. If there are multiple AUTO_INCREMENT columns, this function should not be used even if it will return a value.

Parameter-Liste

conn_identifier: The connection identifier previously obtained by a call to cubrid_connect.

Rückgabewerte

A string representing the ID generated for an AUTO_INCREMENT column by the previous query, on success.

0, if the previous query does not generate new rows.

FALSE on failure.

Changelog

Version	Beschreibung
8.4.0	Change the return value from an array to string; Remove the first parameter class_name.
