Hi
I am tuning my database performance.I found that, the order of field expression in index could cause performance issue

IndexA: FieldA, FieldB, FieldC can be slower than IndexA: FieldC, FieldA, FieldB

I would like to know, how to check if the existing index expression is in A,B,C sequence, then only I drop it and re-create it with C,A,B?

Thank you
