In MS SQL server, can i use a SELECT statement to define a CHECK constraint? Say i have to work with two tables "Customer Master" and "Indian Customer" in ideal situation both tables are compleatly different, and are not interrelated in anyways. however they share the same database

Content of "Customer Master":
CustomerName (colomn): a, b, c, d, e
Branchlocation (colomn): IN, AU, IN, IN, UK

Content of "Indian Customer":
customerID (colomn): 1, 2, 3
CustomerName  (colomn): a, c, d
customer details (colomn): details1, details, details
.
.
.

In Table "Indian Customer" i want to put a constraint so that the users entring data in this table should not be able to enter customers that dont exist in "Customer Master" or whose branch location is not IN. also the tables are in the same project but are not directly related.
