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.
注意 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.
