如何在结果中添加一列以显示序号

Question

我如何修改此 SQL（或创建一个不同的 SQL）以便它在结果中添加一列 - 这将显示以 1 开头并增加 1 的序号

即1、2、3、4等

注意：我不需要添加自增列。如果可能的话，我只需要结果中的递增列

select year, quarter, uploaddate, sum(wagecount) as wagecount from wage_reporting
group by year, quarter, uploaddate
order by year, quarter, uploaddate

预期的结果是这样的

Year	Quarter	UploadDate	WageCount	SequentialNumbers
2021	1	01-JAN-21	2	1
2021	1	02-JAN-21	2	2
2021	1	03-JAN-21	1	3
2021	1	04-JAN-21	5	4

Answer 1

使用ROW_NUMBER:

SELECT year, quarter, uploaddate, SUM(wagecount) AS wagecount,
       ROW_NUMBER() OVER (ORDER BY uploaddate) sequential_numbers
FROM wage_reporting
GROUP BY year, quarter, uploaddate
ORDER BY year, quarter, uploaddate;

Answer 2

使用子查询和 rownum 伪列会有帮助

select your_query.*, rownum
  from (select year, quarter, uploaddate, sum(wagecount) as wagecount 
          from wage_reporting
         group by year, quarter, uploaddate
         order by year, quarter, uploaddate) your_query

Answer 3

select year, quarter, uploaddate, sum(wagecount) as wagecount, SUM(1) OVER (ORDER BY year, quarter, uploaddate) as SequentialNumbers from wage_reporting
group by year, quarter, uploaddate
order by year, quarter, uploaddate

如何在结果中添加一列以显示序号

How do I add a column to the results that would show sequential numbers

oracle

sequential
