fbsql_affected_rows — Get 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.

인수

link_identifier

fbsql_connect()나 fbsql_pconnect()가 반환한 FrontBase 연결 식별자.

선택적이고 지정하지 않았을 때, 함수는 FrontBase 서버로 열려있는 연결을 찾고, 찾지 못하면 fbsql_connect()를 인수 없이 호출했을 때처럼 연결을 시도합니다.

반환값

If the last query failed, this function will return -1.
