## 例

`

     int ingres_num_rows ( resource $result )

`

## 説明

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.

## 戻り値

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.
