how to speed up my query in sql

Question

I create 2 views where the first view gets the details of the asset and other views count the audited asset. I combine the two views to create the main view report but my problem it takes 5 minutes to generate the data and cause timeout error in my application. Can I use the index to speed up my query or do have a trick you use to speed up your query?

Answer 1

You can use index in uniq fields. While you are joining the tables, you can add more filtres. You can check your join parameters. Actually, it depends on your database and views.
