(PHP 4 >= 4.0.6)
fbsql_affected_rows -- Get number of affected rows in previous FrontBase operation
Description
int fbsql_affected_rows (int [link_identifier])
fbsql_affected_rows() returns the number of rows affected by the last INSERT, UPDATE or
DELETE query associated with link_identifier. If the link identifier isn't
specified, the last link opened by fbsql_connect()
is assumed.
Note: If you are using transactions, you need to call fbsql_affected_rows() after
your INSERT, UPDATE, or DELETE query, not after the commit.
If the last query was a DELETE query with no WHERE clause, all of the records will have
been deleted from the table but this function will return zero.
Note: When using UPDATE, FrontBase will not update columns where the new value is the
same as the old value. This creates the possibility that fbsql_affected_rows() may not
actually equal the number of rows matched, only the number of rows that were literally affected by
the query.
If the last query failed, this function will return -1.
