Hi ,

  What is the difference I create a view from TableA with 3 fields and I
select 3 fields from TableA ? Let's assume TableA have 20 field attach to it

  Will it increase the performance when I select from view ?

The view only simplifies access to the table. Instead of using a subquery
you can use a predefined view. It does not impact the query's performance.
