sql 记录一次灾难 游标问题

起因:游标执行存储过程 下载begin 外面了.. ,造成一直触发存储过程

收获:定义变量统一在游标外部使用, 书写内容在begin 内部书写

alter   PROCEDURE  USP_dgd_wzh_INPUT_SAVE    
 @inputrowidhd     VARCHAR(10),
 @doccode          varchar(30)
 as
 DECLARE    @rowid varchar(40)
  begin 


 --游标更改数据
--申明一个游标
DECLARE @po_no varchar(50),@modelcode varchar(50),@size_state varchar(50),@rec_date datetime,@plan_date datetime,

@exdate datetime,@lot_date datetime,@to_country  varchar(50) --循环变量


DECLARE MyCursor CURSOR 


FOR 




 

SELECT     
po_no,modelcode,size_state,rec_date,plan_date,exdate,lot_date,to_country
FROM  po_order_input  where inputrowid  =  @inputrowidhd     and size_state !='码制'
--循环一个游标

--打开一个游标 
OPEN MyCursor


FETCH NEXT FROM MyCursor INTO @po_no,@modelcode,@size_state,@rec_date,@plan_date,@exdate,@lot_date ,@to_country
WHILE @@FETCH_STATUS =0


BEGIN
exec getxxxx @rowid output     
INSERT  INTO  wzh_ddgl_item(Doccode,rowid,ordercode,modelcode,size_state,Orderdate,Originaldate,postdate,lot_date,Portmsg)    
values (@doccode,@rowid, @po_no,@modelcode,@size_state,@rec_date,@plan_date,@exdate,@lot_date ,@to_country)


FETCH NEXT FROM MyCursor INTO  @po_no,@modelcode,@size_state,@rec_date,@plan_date,@exdate,@lot_date ,@to_country
END

--关闭游标
CLOSE MyCursor
--释放资源
DEALLOCATE MyCursor






end 

太久不用忘记游标的写法了
