Re: [GENERAL] speeding up big query lookup
Silvela, Jaime \(Exchange\) [EMAIL PROTECTED] writes: I have a very big table that catalogs measurements of some objects over time. Measurements can be of several (~10) types. It keeps the observation date in a field, and indicates the type of measurement in another field. I often need to get the latest measurement of type A for object X. This is a pretty common requirement, and since plain SQL doesn't handle it very well, different DBMSes have invented different extensions to help. For instance you can use LIMIT: SELECT * from object_val WHERE object_id = X and object_val_type_id = Y ORDER BY object_id DESC, object_val_type_id DESC, observation_date DESC LIMIT 1; This will work very very fast if there is an index on (object_id, object_val_type_id, observation_date) for it to use. The only problem with it is that there's no obvious way to extend it to fetch latest measurements for several objects in one query. Another way, which AFAIK is Postgres-only, is to use DISTINCT ON: SELECT DISTINCT ON (object_id, object_val_type_id) * from object_val ORDER BY object_id DESC, object_val_type_id DESC, observation_date DESC This can give you all the latest measurements at once, or any subset you need (just add a WHERE clause). It's not amazingly fast but it generally beats the bog-standard-SQL alternatives, which as you mentioned require joining against subselects. regards, tom lane ---(end of broadcast)--- TIP 2: Don't 'kill -9' the postmaster

Consider the Slony-I group informed. :-)
We're close to release of version 1.2; moving to pgFoundry is high on
the ToDo list after that, which is pretty compatible with a December
31st close date.

Right. The ticketing system on pgFoundry is sufficiently more
sophisticated that it seems to me to make more sense to manually deal
with them...

We had been putting things off based on that not yet being available,
but that seemed to be a mistake. It would be nice to have Subversion,
