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 TransactSQL 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

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

END
D.
CREATE TRIGGER TRG_TABLES_ON_FIRST
ON ALL SERVER FOR ALTER_DATABASE
