警告

本扩展模块是实验性的。该模块的行为,包括其函数的名称以及其它任何关于此模块的文档可能会在没有通知的情况下随 PHP 以后的发布而改变。我们提醒您在使用本扩展模块的同时自担风险。

For delete, insert or update queries, ingres_num_rows() returns the number of rows affected by the query. For other queries, ingres_num_rows() returns the number of rows in the query's result.

注: This function is mainly meant to get the number of rows modified in the database. If this function is called before using ingres_fetch_array(), ingres_fetch_object() or ingres_fetch_row() the server will delete the result's data and the script won't be able to get them.

You should instead retrieve the result's data using one of these fetch functions in a loop until it returns FALSE, indicating that no more results are available.

See also ingres_query(), ingres_fetch_array(), ingres_fetch_object(), and ingres_fetch_row().
