Oh, and set echo on and autotrace on so we can see this isn't a trigger
trick. That is probably the shortest route to de-mystification.

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.
