Is this the correct syntax to return records only if there are rows of data in the table?
select * from component where exists (select * from component where category='natural') What I'm trying to do is load data into a GUI widget only if it exists. Is is more parsimonious to use only the second 'select' and assume that no records means nothing to be displayed? Rich -- Richard B.
