Instruction

Fantastic! There is one more very important conditional operator – the inequality operator (!= or sometimes <>). Look at the example:

SELECT
  *
FROM User
WHERE Age != 18;

See how easy it is? We used the inequality operator (!=) to select all users who aren't 18 years old.

Exercise

Select all columns for cars that weren't produced in 1999.

Stuck? Here's a hint!

Type:

SELECT
  *
FROM Car
WHERE ProductionYear != 1999;
