SQLserver用游标实现循环 和 简单的量值函数

declare @sums numeric(15,2)    -- 这里必须要写上位数，不然默认为整数
declare @cltno varchar(32)
declare @feeMoney numeric(15,2)
declare cur cursor for sELECT  CltNo FROM  memberinfo WHERE CltNo NOT IN ('00029098','00027565')   -- 定义游标
select @sums = 0.0

fetch next from cur  into @cltno
while @@fetch_status = 0
begin
SELECT @feeMoney = fee
FROM Ns_CMS_Gettable(@cltno,
'2015-10-01',
'22');
select  @sums = @sums + @feeMoney;
