寻找下面查询的替代方案
没有row_number() over(partition by
:
select *,row_number() over(partition by [Tag Name],[PRD] order by [Start Time]) num
from [PRD Project].[Data].[efan1]
答案 0 :(得分:0)
我们可以尝试使用标识列创建table变量,并在此处插入所选数据以获取row_number作为输出
declare @test table (i int identity(1,1), test varchar(10))
答案 1 :(得分:0)
虽然我认为In [306]: B[~A]=''
In [307]: B
Out[307]:
array(['eggs', '', 'cheese'],
dtype='<U6')
可能是最好的方法,但这里有一个替代方案。
设置:
ROW_NUMBER
查询:
CREATE TABLE [#test] ([Col1] CHAR(1) -- This is what we're partitioning by
, [Col2] INT); -- This is what we're ordering by
INSERT INTO [#test]
SELECT CHAR(ABS(CHECKSUM(NEWID()))%16+65) -- Random single letters A:P
, ABS(CHECKSUM(NEWID())) % 1000 -- Random numbers 1:1000
FROM [sys].[objects];
