B. CREATE TRIGGER TrgValidateAccountNumber ON Transactions FOR INSERT AS BEGIN INSERT INTO Transactions SELECT TransactionID,AccountNumber,Amount,TransactionDate FROM inserted WHERE AccountNumber IN (SELECT AccountNumber FROM LoanAccounts UNION SELECT AccountNumber FROM SavingAccounts)) END
C. CREATE TRIGGER TrgValidateAccountNumber ON Transactions INSTEAD OF INSERT AS BEGIN IF EXISTS ( SELECT AccountNumber FROM inserted EXCEPT (SELECT AccountNumber FROM LoanAccounts UNION SELECT AccountNumber FROM SavingAccounts)) BEGIN ROLLBACK TRAN END END
D. CREATE TRIGGER TrgValidateAccountNumber ON Transactions FOR INSERT AS BEGIN IF EXISTS ( SELECT AccountNumber FROM inserted EXCEPT (SELECT AccountNumber FROM LoanAccounts UNION SELECT AccountNumber FROM SavingAccounts)) BEGIN ROLLBACK TRAN END END
