##Question
Is there a way to store a pre-built string or object at application level? so that the application does not have to call the AddConstraint() method every time a user wants to connect to a database
##Answer
Custom constraints can be stored in application through following 3 steps
1) Before adding constraints, put this line of code:
Driver driver = AdHocContext.Driver;
and change all their "AdHocContext.Driver.AddConstraint(…)" lines to "driver.AddConstraint(…)"
2) Add following line of code right before adding first custom constraint:
AdHocContext.Driver.BeginAddingMultipleConstraints();
3) Add following line of code right after adding last custom constraint:
AdHocContext.Driver.EndAddingMultipleConstraints();
