I am new to stackoverflow, I recently went through an interview as graduate developer, and I was asked a question regarding SQL.
Given two table customers and orders, how to find all cusomers who didn't place an order. Can someone tell me what would be a query to achieve this?
--Forgot to mention that I was asked to use JOIN operator for this.
EDIT: I could not find answer to this question as this was technical as well as logical. Therefore, I think my question is different from the one identified as a duplicate.
