hi. I still go on looking for query time. I get a question! explain is a command that estimate cost of query time ok, but I don't know how is the time. for example: mybase=> explain select * from tabla1; NOTICE: QUERY PLAN: Seq Scan on tabla1 (cost=0.00..1.06 rows=6 width=4) EXPLAIN the cost query time is 1.06? 1.06......seconds or milliseconds thanks friends! bye Esteban Gutierrez Abarzua Chillan- Chile ---------------------------(end of broadcast)--------------------------- TIP 6: Have you searched our list archives? http://archives.postgresql.org
