Question – I need to find Customers that buy only “Mobile” product & did not buy any other product So in case of above table, the expected answer is 2 (because Customer 1 & 3 buys AC & Fridge).
I can execute this query in MS SQL Server using “Except” function
SELECT DISTINCT(CustomerID) FROM Table WHERE(Product = 'Mobile') EXCEPT SELECT DISTINCT(CustomerID) FROM Table WHERE(Product != 'Mobile');
Can anyone please provide me the correct query for MySQL as “Except” function is not available in MySQL ?
