Question

I have a table with incremented id from 1,2,3…and so on. What i want is just to sort the data in descending order on the basis of field ‘id’ except first two rows. I tried using below query:-

SELECT * FROM categories ORDER BY CASE WHEN id<3 THEN 0 ELSE id END DESC

It give me the result like

id    name
5     Meal
4     Apparel
3     Electronics
1     Sports
2     Lifestyle

But output should come like

id    name
1     Sports
2     Lifestyle
5     Meal
4     Apparel
3     Electronics

Is there any way to achieve this by using such query?

Answer 1

Try this:

SELECT *
FROM categories
ORDER BY CASE WHEN id < 3 THEN 10000 - id ELSE id END DESC;
-- ----------------------------^
-- use a very large number

Edit:

A better solution which does not require hard coding 10000:

SELECT *
FROM categories
ORDER BY CASE WHEN id < 3 THEN id ELSE 3 END, id DESC
-- ---------------------^              ^
-- ------------------------------------|
-- these numbers must be same
