Oh..no..:crying:

I am pretty sure that there will not be any way, once you said.

Is there any way we can solve from the scratch, or somthing else., because data is loaded already in all 4 tables and they are like 3500+ records...!!!!!

Because in my team...our "Bigheads" don't want us to see the real accounnumber of clients , while we develop any storedprocedure or cursor or even monthly ETL in our test enviornment.

My condition is like , i have to change somthing at data level to make it unidentified in the table with some algorithm or technique, so that other guys can still run the same scripts as they run from several months, but now they want be able to identified individual clients.
