Raja, you did not show the list the count(*)  

Try
clear columns
set feedback on
set echo on
select * from product_component_version; select * from image_staging_table;
select hospital_id from image_staging_table; select acct# from image_staging_table;
select hospital_id, acct# from image_staging_table. select dump(hospital_id) as Hospital_id, dump(acct#) as acct# from image_staging_table;  

This should show what is going on.

Hi,  

Thanks for your reply.  

If the below is true:  

HOSPITAL_ID ACCT#

----------------- -------------

ASHFORD [NULL]
[NULL] X104978978   the select count(*) should result 2 rows. However, my select count(*) is giving one only.  

and when i select a specific col, it is giving value and the feeback is 1 row.

	The first thing that leaps to mind to try to identify the
problem is
	to use NVL() on both columns in your select to display something
(the
	string 'this is NULL' for example) if the value is null, or
maybe do a
	select count(*) from image_staging_table; to check there's only
one
	row.
	
	It's possible that your table might have two rows looking like:
	
	HOSPITAL_ID ACCT#
	----------------- -------------
	ASHFORD [NULL]
	[NULL] X104978978
	
	
	rather than one row such as:
	
	HOSPITAL_ID ACCT#
	----------------- -------------
	ASHFORD X104978978
	
	which is what you are presumably expecting.
