How do I disable auto ordering of SELECT statement in SQL query?
I want to fetch data from database in the order of given ids - IN(9,5,2,10) Problem: The result is fetched in the ascending order Also I don't want the results in descending order. Example: $query = "SELECT * FROM products WHERE id IN(9,5,2,10) So first, data of starting parameter 9 should be fetched in the client computer then 5,2 then at last , id 10. Help is highly appreciated!

Coding San what I mean by this is that from you above mentioned query can be repeated for each individual id.

You can select each one id once.
… where id=9
… where id=5
etc.

You can use CASE.

You can select specific portion of data (2,5,9,10) and then sort them using backend language like php.

Coding San if the ordering is not completely ad-hoc, but based on actual field values, then you can specify ordering even if you don't select the columns that you order by.
For example:
SELECT name
FROM people
WHERE id IN(2, 5, 9)
ORDER BY age

JaScript this is actually for a product CART(e-commerce). Can you clarify your answer in more detail?

Oboh Boniface Emesealu you can enter multiple conditions after WHERE clause and combine them with AND, OR and use parentheses as needed. The conditions can refer to different columns.
