## Description

int ingres_num_rows ( [resource link])

切記!
這個函數是實驗性質的。這個函數的行為、名稱、和關於此函數的任何其他文件在未來PHP的發行中可能會在不通知的情況下改變。 使用此延伸需自行承擔風險。

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.

> 備注: 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.
