<> Not equal. Note: In some versions of SQL this operator may be written as !=
Example sql query:
1) Selecting groceries where price is not 20
SELECT * FROM Grocery WHERE Price <> 20;
<> Not Equal
!= Not Equal
-- returns records where amount is not equal to 400
SELECT order_id, item, amount
FROM Orders
WHERE amount != 400;
row <> value
-- returns records where customer_id is only 4
SELECT order_id, item, amount
FROM Orders
WHERE customer_id = 4;
SELECT *
FROM Customers
WHERE first_name = 'John';
