MySQL Double Equal Sign

Question

I\'m debugging an old website, and I get some SQL errors. When I went through it, I found the following query.

UPDATE boats
set    new_high_date == DATE_ADD(         


        

Answer 1

That is incorrect, there is no double equal sign in sql. The correct way to set is

UPDATE boats 
SET    new_high_date = DATE_ADD(NOW(), INTERVAL 3 MONTH)
WHERE  id = 49701

Answer 2

There is no double equal in MySQL so you should remove it.

Answer 3

Blindly you can remove them because MYSQL doesn't have any ==
