设在SQL Server 2008某数据库中建有如下会员卡表:
CREATE TABLE Table_Card (
CardID char(4) PRJMARY KEY,
StartDate datetime NOT NULL,
Score int NOT NULL DEFAULT 0,
State int NOT NULL CHECK (State in (0,1,2))
)
现表中无数据,某用户对此表依次进行了如下操作:
Ⅰ. INSERT INTO Table_Card
VALUES ('1001 ','2012-1-1 12:30:01 ',154,0)
Ⅱ . INSERT INTO Table_Card ( CardID, StartDate, State)
VALUES ('1002','2012-1-1 12:30:02',1)
Ⅲ. INSERT INTO Table_Card
VALUES ('1003','2012-1-1 12:30:03 ',172,2)
IV. INSERT INTO Table_Card
VALUES (' 1004','2012-1-1 12:30:04',135,3)
V. UPDATE Table_Card SET State = 3 WHERE CardID ='1001 '
VI. UPDATE Table Card SET State = 1 WHERE CardID='1004'
以上操作对Table_Card表数据产生影响的是()
