Hi Meenu
I cannot look into the future, so I may be wrong, in fact I will probably be wrong.
But I believe what will happen now is this:
1. You'll somehow hear about dynamic SQL and get all excited about it as it seems to solve your problem.
2. You stop looking for a solution, because you think you found the perfect answer at step 1. And when the problems with this approach start to surface you likely won't be there (as you are the developer of the system, not the user, administrator or maintainer).
Please carefully think about the requirement here.
You have a query that you want to run against a table in a schema of which both is unknown at the time you design the query.
What kind of super-clever-flexible data design might that be?
