i have 3 diffrent tables. 1) US rate data 2)CANADA rate data and 3)MEXICO rate data. All 3 tables have 6 collumns each. 4 collumns are commun to all tables and 2 are diffrent. Now at target i want single table say Country rate which will have (4+2+2+2+1 flag) 11 collumns. I will add a flag collumn which will indicate country and will put nullable collumns which are not common to other. How i can implement this in datastage?
