You have a casting error; instead of: > dbr=# SELECT extract(EPOCH FROM INTERVAL b) FROM a; > ERROR: syntax error at or near "b" > LINE 1: SELECT extract(EPOCH FROM INTERVAL b) FROM a; use SELECT extract(EPOCH FROM b::INTERVAL) FROM a; or SELECT extract(EPOCH FROM CAST (b AS INTERVAL)) FROM a; Regards Ian Barwick -- Sent via pgsql-sql mailing list (pgsql-sql@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-sql
