# fbsql_insert_id

(PHP 4 >= 4.0.6)

fbsql_insert_id -- Get the id generated from the previous INSERT operation

## Description

``int fbsql_insert_id` (resource [link_identifier])`

fbsql_insert_id() returns the ID generated for an column defined as DEFAULT UNIQUE by the previous INSERT query using the given `link_identifier`. If `link_identifier` isn't specified, the last opened link is assumed.

fbsql_insert_id() returns 0 if the previous query does not generate an DEFAULT UNIQUE value. If you need to save the value for later, be sure to call fbsql_insert_id() immediately after the query that generates the value.

> Note: The value of the FrontBase SQL function `LAST_INSERT_ID()` always contains the most recently generated DEFAULT UNIQUE value, and is not reset between queries.
