Re: limiting access to (through) views

Thanks,

Now is it possible to do the following:

select table1.* from
table1, table2 where
table1.col3=table2.key and
table2.username like 'CURRENT_USER%'

This is returning nothing when I know it should be returning something, so I
think that since the CURRENT_USER is in the ' it is not executing the
function. Is there a way to make that execute using the like with the regex
matching (%)?

Thanks
