<?php
/* connect to database */
sybase_connect('SYBASE', '', '') or


                die("Could not connect");

                sybase_select_db("db");


                
sybase_query("DELETE FROM sometable WHERE id < 10");

This command is not effective for SELECT statements, only on statements which modify records. To retrieve the number of rows returned from a SELECT, use sybase_num_rows().
