Sql server存储过程中常见游标循环用法

@A1 VARCHAR(10), @A2 VARCHAR(10), @A3 INT DECLARE YOUCURNAME CURSOR FOR SELECT A1,A2,A3 FROM YOUTABLENAME OPEN YOUCURNAME fetch next from youcurname into @a1,@a2,@a3 while @@fetch_status<>-1 begin --您要执行的操作写在这里 fetch next from youcurname into @a1,@a2,@a3 end close youcurname deallocate youcurname

再加上异常捕捉和事务，完整过程如下：

Create PROCEDURE  [dbo].[Usp_CreatePanicBuyingCode](
 @OrderNumber VARCHAR(50))
AS  
DECLARE 
@A1 VARCHAR(10),
@A2 VARCHAR(10),
@A3 INT
  begin try  
    begin tran 
   DECLARE youcurname CURSOR  FOR SELECT A1,A2,A3 FROM YOUTABLENAME
OPEN youcurname
fetch next from youcurname into @a1,@a2,@a3
while @@fetch_status<>-1
begin
--您要执行的操作写在这里
fetch next from youcurname into @a1,@a2,@a3
end
close youcurname
deallocate youcurname
COMMIT TRAN  
end try   
begin catch   
    ROLLBACK  
end catch
