-- sp_Compare2Tables
--
-- The SP compares the structure & data in 2 tables.
-- Tables can be from different servers, different databases or different schemas.
--------------------------------------------------------------------------------------------------------------
-- Parameters:
-- 1. @Table1 - Name of the table to be checked.
-- 2. @Table2 - Name of the table to be checked.
-- 3. @ListDiff - Bit to list the differences
-- 4. @StructureOnly - Bit to compare only the structure
--
-- Assumptions:  The length of the dynamic string should not exceed 4000 characters
--    Both tables have primary keys
--    Primary key combination is same for both tables
-- Paramenter 1, 2: Table name (With optional server name, database name, Schema name seperated with .)
--     Eg. Preethi.Inventory.Dbo.TranHeader, Preethi.Test.dbo.Tran
--        Any of the first 3 parts could be omitted.
--        Inventory.DBO.TranHeader, INV.TranHeader and TranHeader are valid
-- Parameter 3: List the differences
--    IF True it will list all the different fields (in case of structural difference)
--     or all the different entries (in case of data differences)
--     Default is 1 (List the differences)
-- Parameter 4: Compare only the structure
--     Default=0 (Compare data & structure)
