Hi Ronnie,
There is one alternative. Please check if the following code helps you.
select
(case when record_count > 0 then EMP_ID end) "EMP_ID"
, (case when record_count > 0 then ENAME end) "ENAME"
from EMP a, (select record_count from m_cs_tables where schema_name = 'MY_SCHEMA' and table_name = 'EMP' ) b;
Regards,
Ravi
