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.
