PHP 5.5.15 is released

fbsql_affected_rows

(PHP 4 >= 4.0.6, PHP 5)

fbsql_affected_rowsGet number of affected rows in previous FrontBase operation

说明

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.

参数

link_identifier

fbsql_connect()fbsql_pconnect() 返回的 FrontBase 链接标识符.

如可选并未指定,函数会尝试查找一个到 FrontBase 服务器的开放链接,且如没有找到这样的链接,会尝试通过不带参数调用 fbsql_connect() 来创建一个。

返回值

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