What is the meaning of <> in mysql query?

I have a MySQL query that includes <> in it. I don\'t know the exact usage of it.

Answer 1

In MySQL, <> means Not Equal To, just like !=.

mysql> SELECT '.01' <> '0.01';
        -> 1
mysql> SELECT .01 <> '0.01';
        -> 0
mysql> SELECT 'zapp' <> 'zappp';
        -> 1
