QUESTION NO: 1
You develop a Microsoft SQL Server 2012 database that has two tables named
SavingAccounts and LoanAccounts. Both tables have a column named AccountNumber of the nvarchar data type.
You use a third table named Transactions that has columns named TransactionId AccountNumber,
Amount, and TransactionDate.
You need to ensure that when multiple records are inserted in the Transactions table, only the records that have a valid AccountNumber in the SavingAccounts or LoanAccounts are inserted.
Which Transact-SQL statement should you use?

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
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
INSTEAD OF INSERT

You are a database developer of a Microsoft SQL Server 2012 database.
You are designing a table that will store Customer data from different sources. The table will include a column that contains the CustomerID from the source system and a column that contains the
SourceID.
A sample of this data is as shown in the following table.

CustomerID int NOT NULL,
CustomerName varchar(255) NOT NULL,
CONSTRAINT PK_Customer PRIMARY KEY CLUSTERED
(SourceID, CustomerID));
B. CREATE TABLE Customer

QUESTION NO: 3
A local bank uses a SQL Server database to manage accounts. You are developing a stored procedure that contains multiple Transact-SQL INSERT statements.
The stored procedure must use transaction management to handle errors.
You need to ensure that the stored procedure rolls back the entire transaction if a run-time occurs.
Which Transact-SQL statement should you add to the stored procedure?
A. SET ARITHABORT ON
B. SET NOEXEC ON
C. SET XACT_ABORT ON
D. SET TRANSACTION ISOLATION LEVEL ON
Answer: C
Explanation
SET XACT_ABORT specifies whether SQL Server automatically rolls back the current transaction when a Transact-SQL statement raises a run-time error.
When SET XACT_ABORT is ON, if a Transact-SQL statement raises a run-time error, the entire transaction is terminated and rolled back.
