ingres_num_rows — Get the number of rows affected or returned by a query
Описание
$result
)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.
Замечание:
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.
