ingres_num_rows — Get the number of rows affected or returned by a query

说明

int ingres_num_rows ( resource $result )

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.

参数

result: The result identifier for a query.

返回值

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.
