I have a database with a btree index on the 'removed' field, which is of type 'date'. However it isn't being used:
techdb2=> explain select * from lines where removed > CURRENT_DATE; QUERY PLAN ------------------------------------------------------------ Seq Scan on lines (cost=0.00..243.47 rows=2189 width=324) Filter: (removed > ('now'::text)::date) (2 rows) Now the weird thing is that if I select a range it is being used: techdb2=> explain select * from lines where removed > CURRENT_DATE and removed < '9999-01-01'; QUERY PLAN ------------------------------------------------------------------------------------ Index Scan using lines_removed_idx on lines (cost=0.00..120.56 rows=33 width=324) Index Cond: ((removed > ('now'::text)::date) AND (removed < '9999-01-01'::date)) (2 rows) Why is this? (Tested with both 7.3.2 and 7.4.6) Mike. ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
