fbsql_affected_rows
(PHP 4 >= 4.0.6, PHP 5 < 5.3.0)
fbsql_affected_rows — Get number of affected rows in previous FrontBase operation
Descrição
$link_identifier = ?
) : int
fbsql_affected_rows() returns the number
of rows affected by the last INSERT, UPDATE or DELETE query
associated with link_identifier.
Nota:
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.
Nota:
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.
