sesam_affected_rows — Get number of rows affected by an immediate query
說明
int sesam_affected_rows
( string $result_id
)
Gets the number of rows affected by an immediate query.
The sesam_affected_rows() function can only return useful values when used in combination with "immediate" SQL statements (updating operations like INSERT, UPDATE and DELETE) because SESAM does not deliver any "affected rows" information for "select type" queries.
Return值
Returns the number of rows affected by a query associated with result_id .
