SqlServer基础：游标

记录下今天用到的 游标 ： DECLARE @TempID INT DECLARE @Number INT SET @Number=1 DECLARE myCursor CURSOR FOR SELECT MemberID FROM dbo.Member OPEN myCursor FETCH NEXT FROM myCursor INTO @TempID WHILE(@@fetch_status=0) BEGIN UPDATE dbo.Member

记录下今天用到的游标：

DECLARE @TempID INT
DECLARE @Number INT
SET @Number=1
DECLARE myCursor CURSOR FOR 
    SELECT MemberID FROM dbo.Member
OPEN myCursor
FETCH NEXT FROM myCursor INTO @TempID

WHILE(@@fetch_status=0)
    BEGIN
        UPDATE dbo.Member
            SET MemberName='测试会员'+ CONVERT(VARCHAR,@Number,50)
            WHERE MemberID=@TempID
        SET @Number=@Number+1
        FETCH NEXT FROM myCursor INTO @TempID
    END
CLOSE myCursor
DEALLOCATE myCursor
