Popisint fbsql_insert_id ( [resource link_identifier] )
Gets the id generated from the previous INSERT operation which created a DEFAULT UNIQUE value.
Poznámka: The value of the FrontBase SQL function fbsql_insert_id() always contains the most recently generated DEFAULT UNIQUE value, and is not reset between queries.
Returns the ID generated from the previous INSERT query, or 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 this function immediately after the query that generates the value.
