fbsql_affected_rows

(PHP 4>= 4.0.6, PHP 5)fbsql_affected_rows -- Get number of affected rows in previous FrontBase operation

Описание

int fbsql_affected_rows ([resource 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.

Замечание: 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.

Замечание: 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.
