Eg. SELECT col1, col2, col3,....col10 FROM table1; For above query If I didn't mention ORDER BY clause, then I want to know selected data will appear in which order by a query planner?
Because I have huge size table, and when I applied ORDER BY col1, col2..in query the performance is soo bad that I can't offred. What should I do ? Because my requirement is data with ordered column. -- View this message in context: http://postgresql.1045698.n5.nabble.com/Order-By-Clause-Slows-Query-Performance-tp5777633.html Sent from the PostgreSQL - performance mailing list archive at Nabble.com. -- Sent via pgsql-performance mailing list (pgsql-performance@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
