Hi,
I have a table with a lot of fields and I would want to obtain a quicker
query response.
The main characteristics are:
The table is NOT often updated, I mean INSERT and UPDATE are sporadic
sentences, but SELECT sentences are often executed.
The most used query is something like
select distinct field1 from my_table where field1 is not null and field2
like '...'
Should I use a BTREE index or would be better to use a HASH or RTREE ?
Thanks,
Gabi :-)
