Question

I realize this is likely to be an easy one, but my SQL is basic at best.

Lets say I have a table containing a list of orders, with item_id being one of the columns. I need to display the 3 least (or 3 most) popular orders of item.

I know that I need to group the orders using item_id and then count them. Then I need to display the bottom (or top) 3 in descending (or ascending) order. I’m just not entirely sure how to construct a query like that.

Answer 1

In Sql Server:

SELECT TOP 3 item_id, COUNT(*) as itemcount 
FROM table 
GROUP BY item_id ORDER BY itemcount

And add DESC to order descent
