Savita,
I assume the problem is the subquery...
You can't add the two select count(*) queries together like that. A valid
option is to use a sum function like this:
select record_identifier from records where rownum<(40-(select sum(num)
from (select count(*) num from customer_view union all select count(*) from
unit view)));
The "union all" is important incase two counts are the same (union on its
own would halve the result). The alias "num" is given to the first column
so that there is something to enter in the sum clause.
Regards,
Mark.
PS: There are other ways of doing this also.

to ORACLE-L
Hi All,
I want to know about one query.
I have two views and I want to get the sum of count of two view ex
I have a query like
select record_identifier from records where rownum<(40-(select count(*)
from customer_view+select count(*) from
unit_view));
But this is not working in oracle.
Is there any other way to do this without writing a function
