ingres_num_rows

(PHP 4 >= 4.0.2, PHP 5 < 5.1.0, PECL ingres >= 1.0.0)

ingres_num_rowsGet the number of rows affected or returned by a query


说明

ingres_num_rows ( resource $result ) : int

This function primarily is meant to get the number of rows modified in the database. However, it can be used to retrieve the number of rows to fetch for a SELECT statement.

Note:

If scrollable cursors are disabled and 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 will be unable to get them.

Instead, you should 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.
