Yes. Otherwise you can use UPDATEs to infer something about the content
of the table, eg doupdate table1 set field1 = field1 where field2 = yy
and note the result count to find out whether there are any rows with
field2 = yy. If you didn't give the other guy SELECT rights then
presumably you do not want him to be able to infer any such thing.
