Question

我想知道在SQL Server中是否可以这样做：

我的表格如下：

 CREATE TABLE MEMBERSHIP
(
    Memebership_ID INT IDENTITY(1,1)PRIMARY KEY NOT NULL,   
    MemberShip_Expiry_Date Datetime,
    Member_Account_Balance Money,
    Member_Blacklisted bit ,--(0 for no, 1 for yes)
    Customer_ID INT not null,
    Last_Payment datetime
)

我想知道如果Member_Blacklisted超过6个月后，是否可以使用带有或不带游标的存储过程来更改Last_Payment列插入例如

DECLARE @MemberID int,@Date datetime

到目前为止我的尝试：

DECLARE @MemberID int,@Date datetime

-- Declaring the Cursor. 
DECLARE C_Expired_Penalty_BlackList CURSOR
FOR
(
 SELECT 
 FROM MEMBERSHIP
)

-- Open the Cursor declared.
OPEN C_Expired_Penalty_BlackList
FETCH NEXT FROM C_Expired_Penalty_BlackList INTO @MemberID,@Date
WHILE @@FETCH_STATUS = 0
BEGIN
 IF @Date > DATEPART(MONTH,getdate()+6)
 BEGIN
  update MEMBERSHIP
  set Member_Blacklisted = 1
  Where Memebership_ID = @MemberID 
 END
  FETCH NEXT FROM C_Expired_Penalty_BlackList INTO @MemberID,@Date
END

CLOSE C_Expired_Penalty_BlackList
DEALLOCATE C_Expired_Penalty_BlackList

Answer 1

试试这个：

UPDATE MEMBERSHIP 
SET Member_Blacklisted = 1 
WHERE Last_Payment < DATEADD(Month, -6, GETDATE())

SQL Server存储过程/游标
