Subject: Re: [SQL] Substracting Date field from integer value in another field

Try this:
SELECT ACS_TIMESTAMP - acct_session_time * '1 second'::interval FROM RADIUS_ACC_48

2017-08-30 6:20 GMT-05:00 Abdul Hameed <atheequeahmed(at)gmail(dot)com<mailto:atheequeahmed(at)gmail(dot)com>>:
Getting below error.

ERROR: operator does not exist: timestamp with time zone - bigint
LINE 65: ACS_TIMESTAMP-acct_session_time/(24*60*60) ELSE ACS_TIMESTAM..

I have a table with one column as timestamp (Logon Time), another column as integer(seconds).
I would like to deduct the logon time(timestamp) – integer field(seconds) to get the final value in TIMESTAMP format.

SELECT ACS_TIMESTAMP - acct_session_time FROM RADIUS_ACC_48

ERROR: operator does not exist: timestamp with time zone - bigint
LINE 65: ACS_TIMESTAMP-acct_session_time/(24*60*60) ELSE ACS_TIMESTAM..

Please let me know the syntax for that.
