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

Descrizione

int ingres_num_rows ( resource $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.

Nota:
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.

Elenco dei parametri

result: The result identifier for a query
