Tips for Better JDBC querying

Hi e'body,

Well, I am in a project where you query {DB2} database tables, having more than a million records;

So what do you guys think is a better way to handle such a situation??

I anyway use DataSource Connection Pooling;
any tips on optimized ways of querying is greatly appreciated..!!

looking forward to hear from you guys.. i know, you guys have great ideas..
Thanks :-)

PS: if anyone can forward links where i can find optimized ways of querying, that would be great

Prashant,
The most important thing is well though out indexes. Also, run your queries through db2 explain to find optimizations.

but indexes doesn't help in full table scan. i think we should avoid full table scans in these kind of situations.

tips:

- indexes help in query
- indexes may suck when there is lots of updates

so be careful

Adeel,
I agree with what you said. As Prashant's table has millions of rows, a full table scan is unlikely to be occuring.
