SQL cursor用法实例

代码如下:

DECLARE @OldId varchar(50)   
DECLARE @CustomerID varchar(50)   
DECLARE My_Cursor CURSOR --定义游标   
FOR (select CustomerID,oldid from Customer where Area='bj') --查出需要的集合放到游标中   
OPEN My_Cursor; --打开游标   
FETCH NEXT FROM My_Cursor INTO @CustomerID,@OldId; --读取第一行数据   
WHILE @@FETCH_STATUS = 0      
    BEGIN     
       DECLARE @OtherPro VARCHAR(500)   
       DECLARE @StatusID varchar(200)   
       DECLARE @Userid varchar(200)   
       DECLARE @FinalUserid varchar(200)   

      SELECT @OtherPro=OtherPro,@StatusID=CustomerStatusID,@Userid=UserID FROM bjsunmis.dbo.Customer WHERE CustomerID=@OldId;   

      SELECT @FinalUserid=UserID from Users where oldid=@Userid   

      INSERT INTO CustomerotherInfo(CustomerID,OtherPro,CustomerStatusID,UserID)VALUES(@CustomerID,@OtherPro,@StatusID,@FinalUserid)   

     FETCH NEXT FROM My_Cursor INTO @CustomerID,@OldId; --读取下一行数据       
    END  
CLOSE My_Cursor; --关闭游标   
DEALLOCATE My_Cursor; --释放游标   
GO
