如何反转来自已包含ORDER BY的SQL查询的表

Question

Here is my query:

SELECT TOP 8 id, rssi1, date
FROM history
WHERE (siteName = 'CCL03412') 
ORDER BY id DESC

This the result:

How can I reverse this table based on date (Column2) by using SQL?

Answer 1

You could simply use a sub-query. If you apply a TOP clause the nested ORDER BY is allowed:

SELECT X.* FROM(
  SELECT TOP 8 id, Column1, Column2
  FROM dbo.History
  WHERE (siteName = 'CCL03412') 
  ORDER BY id DESC) X
ORDER BY Column2

Demo

The SELECT query of a subquery is always enclosed in parentheses. It cannot include a COMPUTE or FOR BROWSE clause, and may only include an ORDER BY clause when a TOP clause is also specified .

Answer 2

You can use the first query to get the matching ids, and use them as part of an IN clause:

SELECT id, rssi1, date
FROM history
WHERE id IN
(
    SELECT TOP 8 id
    FROM history
    WHERE (siteName = 'CCL03412') 
    ORDER BY id DESC
)
ORDER BY date ASC

Answer 3

didn't run it, but i think it should go well

WITH cte AS 
(
    SELECT id, rssi1, date, RANK() OVER (ORDER BY ID DESC) AS Rank
    FROM history
    WHERE (siteName = 'CCL03412')
)
SELECT id, rssi1, date
FROM cte
WHERE Rank <= 8
ORDER BY Date DESC

Answer 4

try the below :

select * from (SELECT TOP 8 id, rssi1, date
FROM history
WHERE (siteName = 'CCL03412') 
ORDER BY id DESC ) aa order by aa.date DESC

Answer 5

I have not run this but i think it will work. Execute and let me know if you face error

select id, rssi1, date from (SELECT TOP 8 id, rssi1, date FROM history WHERE (siteName = 'CCL03412') ORDER BY id DESC) order by date ;
