What is the meaning of <> in mysql query?

<> is standard ANSI SQL and stands for not equal or !=.

<> means NOT EQUAL TO, != also means NOT EQUAL TO. It's just another syntactic sugar. both <> and != are same.

The below two examples are doing the same thing. Query publisher table to bring results which are NOT EQUAL TO <> != USA.

SELECT pub_name,country,pub_city,estd FROM publisher WHERE country <> "USA";

SELECT pub_name,country,pub_city,estd FROM publisher WHERE country != "USA";

<> means not equal to, != also means not equal to.
