Hello everyone,

When I perform a query on table, the query result is kind of slow. How do I check the database and how I do make query faster?

I'm using Oracle9i 9204 on Sun Solaris 9.

Thank you.

"Query is slow" is your subjective feeling, or did you measure it? What does Explain Plan say about it? Do you have your tables and indexes analyzed? Do you have indexes at all? Are they used?

How to make a query faster? Tune it!
