SQL WHERE condition is not equal to?

Question

Is it possible to negate a where clause?

e.g.

DELETE * FROM table WHERE id != 2;

Answer 1

Your question was already answered by the other posters, I'd just like to point out that

 delete from table where id <> 2

(or variants thereof, not id = 2 etc) will not delete rows where id is NULL.

If you also want to delete rows with id = NULL:

delete from table where id <> 2 or id is NULL
