allows you to set the next row to be returned from the resultset.
say you open a recordset and iterate through it. you can use mysql_data_seek to reset the pointer (the next row to be returned).
ferinstance say you are creating "pages" of data. you coudl open the recordsset, then jump to the first row you want. if say your number of rows per page is 30, and you want page 5 then mysql_data_seek($result, 149) would set the internal row pointer int he resultset to row 150, bearing in mind its a zero based counter
I'd rather be riding on the Tiger 800 or the Norton
