Sender jdbc adapter needs to only read the data but not update for testing.Is this possible?

I have a JDBC to proxy scenario.But the source team has only one DB and that is Production, for this new interface I have to use that DB for testing purpose.Now, since that is Prod system , I can't update anything in that.So is there any way that I can only read from the source DB but do not update it in SQL query?

Answer:

use  <TEST> in update query.
