AC2 and BC2 are derived values and always changes. CC1 is sum (AC1)*AC2 and CC2 = Sum (BC1)*BC2 In my UI I need show these calculated values from all these tables. If the user likes to save I need to lock the values and save AC2, BC2, CC1, CC2.we are planning to use views for this but views are really slow. What is the alternative approach?

Answer 1

You just need to use indices, then you will get faster views. Every column that appears in a group by statement, order by statement or in a condition makes views faster when indexed. If you have expressions like: select ... where A=... group by B order by C

Then you'd better make A, B and C indices
