Performance issue with Jet4 (Access2000) and queries with like
Dear Newsgroup,
Well, as we figured out here, queries with 'like' and no joker are much
slower with Jet 4.0.
e.g.
Select * from atable where astringfield like "avalue"
is much slower then
Select * from atable where astringfield like "avalue*"
especially in huge tables these statements decrease performance.
Well, i know it's somehow more bad style than a 'bug' but it's a pitty
anyway.
Just wanted to let you know...
regards, yves.
