Question

This should be a very simple code, but I can’t figure it out. Basically I want to JOIN two tables. One of the tables has the name of the user and the other table has all the orders that
that user submitted. I want a list of all the users, ORDERED by the user who has submitted the most orders. Is this possible using JOIN?

SELECT COUNT(table1.Orders)
        , table2.Name 
    FROM table1 
        LEFT JOIN table2 ON table1.IDName = table1.IDName 
ORDER BY COUNT(table1.Orders)

This is the code I have right now. Thanks for taking a look at this, I look forward to hearing your responses.

You probably need to use GROUP BY and sort by decreasing order. Your JOIN is wrong, I replaced table1.IDName with table2.IDName:

SELECT COUNT(table1.Orders) AS nb, table2.Name
FROM table1
LEFT JOIN table2 ON table1.IDName = table2.IDName
GROUP BY table.Name
ORDER BY nb DESC
