Hi, I tried the following on 7.1.3-38 and pgsl used the index:
EXPLAIN mp3base=# explain mp3base-# select * from mp3_ mp3base-# where name ~ '^cre'; NOTICE: QUERY PLAN: Index Scan using mp3_name on mp3_ (cost=0.00..8.14 rows=10 width=28) On an other machine I've a psql 7.2-1 and I got this result: mp3base=# explain mp3base-# select * from mp3_ mp3base-# where name ~ '^cre'; NOTICE: QUERY PLAN: Seq Scan on mp3_ (cost=0.00..2150.93 rows=363 width=794) On both machines is this index: CREATE INDEX "mp3_name" ON mp3_(name); Do you have any idea why it dosn't work with 7.2 ???? And what can I do to use the index ???? (7.2 runs on a mandrake and 7.1.3 on suse both databases are created as: createdb -E LATIN1 mp3base Thx Holger ______________________________________________________________________________ Keine verlorenen Lotto-Quittungen, keine vergessenen Gewinne mehr!
