QUESTION 71
You need to ensure that tables are not dropped from your database.
What should you do?

A.    Create a DDL trigger that contains COMMIT.
B.    Create a DML trigger that contains COMMIT.
C.    Create a DDL trigger that contains ROLLBACK.
D.    Create a DML trigger that contains ROLLBACK.

Answer: C
Explanation:
DDL triggers can execute either when a DDL statement is executed or when the user logs on to the SQL Server instance.
DDL triggers can be scoped at either the database or instance level.
To scope a DDL trigger at the instance level, you use the ON ALL SERVER option.
To scope a DDL trigger at the database level, you use the ON DATABASE option.
The following is an example of a DDL trigger:
CREATE TRIGGER tddl_tabledropalterprevent
ON DATABASE
FOR DROP_TABLE, ALTER_TABLE
AS
PRINT ‘You are attempting to drop or alter tables in production!’
ROLLBACK;
Almost all DDL commands run within the context of a transaction. Because a DDL trigger also runs within the same transaction context, any DDL statement running in the context of a transaction can be rolled back.

QUESTION 72
You are responsible for a SQL Server database.
You require the tables to be added or altered only on the first day of the month.
You need to ensure that if the tables are attempted to be modified or created on any other day, an error is received and the attempt is not successful.
Which Transact-SQL statement should you use?

A.    CREATE TRIGGER TRG_TABLES_ON_FIRST
ON DATABASE FOR CREATE_TABLE
AS
IF DATEPART(day,getdate())>1
BEGIN
RAISERROR (‘Must wait til next month.’, 16, 1)
END
B.    CREATE TRIGGER TRG_TABLES_ON_FIRST
ON DATABASE FOR CREATE_TABLE,ALTER_TABLE
AS
IF DATEPART(day,getdate())>1
BEGIN
RAISERROR (‘Must wait til next month.’, 16, 1)
END
C.    CREATE TRIGGER TRG_TABLES_ON_FIRST
ON DATABASE FOR CREATE_TABLE,ALTER_TABLE
AS
IF DATEPART(day,getdate())>1
BEGIN
ROLLBACK
RAISERROR (‘Must wait til next month.’, 16, 1)
END
D.    CREATE TRIGGER TRG_TABLES_ON_FIRST ON ALL SERVER FOR ALTER_DATABASE
AS
IF DATEPART(day,getdate())>1
BEGIN
ROLLBACK
RAISERROR (‘Must wait til next month.’, 16, 1)
END
