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. ________________________________ From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of raja rao Sent: Friday, October 28, 2005 8:34 AM To: stephen booth Cc: oracle list Subject: Re: strange behaviour in select statement 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. stephen booth <stephenbooth.uk@xxxxxxxxx> wrote: On 28/10/05, raja rao wrote: > > when i select more than 1 column, some colums data is missing.

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.
