SQL Server Clustered Index - Order of Index Question

Question

I have a table like so:

keyA keyB data

keyA and keyB together are unique, are the primary key of my table and make up a clustered index.

Answer 1

The best thing you can do is to try both solutions and measure the execution time.

In my experience, index tuning is all but exact-science.

Maybe having keyB before keyA in the index column order would be better
