here is some sample data from a table named Customer

CustId   Birthdate
1            05/07/1970
2            05/07/1970
3           05/07/1970

here is some sample data from a table named OrderHistory

CustID    OrderDate        OrderAmount
1              05/07/2019      200
2              05/06/2019      300
3              05/08/2019      400

Trying to write a query that will return the age of the customer as of the order date

in example above, query should return

custid  orderdate           ageasoforderdate

1           05/07/2019       49
2           05/06/2019      48
3           05/08/2019       49
