So you only help on this list when are you paid? Why are you speaking about
others as "WE". I am sure you must have learnt a lot from this list without
paying a dime to anyone. Has anyone ever made such a bizzare statement to
you?
Mine is a valid business requirement. We want to pull the data periodically
from databases A and B and merge into C without opening any security risk to
C. All databases are exactly same. I will appreciate if you can tell what is
so onerous about it. Is this something that cannot be implemented???
