Коментарии
This function works exactly like its equivalent Microsoft SQL Server function: mssql_next_result(). The information above is rather vague and a bit misleading, so refer to the mssql version of this function for details on to use it properly.
P.S. It works with stored procedures.
Using dbase always returns false or -1. It won't work. Just like odbc_num_rows.
