fbsql_affected_rows

(PHP 4 >= 4.0.6, PHP 5, PHP 7)

fbsql_affected_rowsGet number of affected rows in previous FrontBase operation

설명

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.

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.

반환값
