SQL游标的简单使用
CREATE PROCEDURE [dbo].[pro_CURSOR]
AS
BEGIN
--声明一个游标
DECLARE MyCURSOR CURSOR FOR
SELECT userid,depid FROM users
--打开游标
open MyCURSOR
--声明两个变量
declare @userid varchar(50)
declare @depid varchar(50)
--循环移动
fetch next from MyCURSOR into @userid,@depid
while(@@fetch_status=0)
begin
update users set description=(select dep_des from department where depid=@depid)
where userid=@userid
fetch next from MyCURSOR into @userid,@depid
end
close MyCURSOR
deallocate MyCURSOR
END
