Hello

I need a sql query to a postgresql database which can tell me whether the
rows returned ar equal.

i.e

-------
Status
-------
Order
-------
Collected
----------


This is two columns. Both are not equal.

Any help?.......without having to write code to fetch the result and go
through etc etc.

thanks
marios

Sorry - don't think so. Unless you've defined a unique index on one or 
more of these columns you'll have to check the contents of the columns. 
If they are never supposed to be the same, define a unique index.
