如何使用CTE对前一行进行递归？

Question

我有一个问题，我认为可以使用CTE解决。

我创建了如下所示的SQL查询：

with CTE as
(
SELECT Distinct T.testType as name,'tmpRequirement_TestType_Canvas' as template,'n/a' as layout,
0 as x,0 as y,'855' as width,'42' as height,
T.id,T.testType FROM [dbo].[tProperty] P
INNER JOIN tTest_Type T 
on P.tTest_Type_id = T.id)

select * from CTE

我得到如下结果：

我想得到的如下所示：

基本上我希望'y'每行增加50。有什么办法吗？

提前致谢。

Answer 1

您需要订购，但row_number()会执行此操作：

select . . .,
       50 * row_number() over (order by ?) as y
from cte;

?用于指定排序的列。

Answer 2

作为您上面的样本：

这将从0开始，加50：

select setNumber from 
(select setNumber from
(select 50 * ROW_NUMBER() over(order by id) as setNumber from yourTableOrCTE) as a
union all
select 0) as a order by setNumber
