Some calculations on a table

  • 15 years ago

    i have a table with these colums:

    Balance   TransactionAmount   TransactionType        NewBalance

    200          25                                 1                              225

    200         40                                    2                              160

    what i want to do is make a query that will calculate the new balance as follows:

    if the transactionType is 1 it will add the Balance+TransactionAmoun

    if the transactionType is 2 it will get the difference

    please help
