Question

I have this query:

SELECT id, name FROM users
WHERE ((id = 1) OR (5 <= 5))

This should result all records as 5 = 5, but it’s not. It’s only resulting records where the id = 1.

What am I doing wrong?

EDIT:
This is the full query:

SELECT project_id, project_name, project_description, project_active, 
            users.user_firstname, users.user_lastname FROM projects 
            INNER JOIN users ON projects.user_id = users.user_id 
            WHERE (projects.user_id = 1 || 3 <= 3)

EDIT:
Found it =/
Something was wrong with the join; user_id didn’t exist anymore for some reason.

Answer 1

Try:

EXPLAIN EXTENDED SELECT id, name FROM users where id=1 or 5<=5;

SHOW WARNINGS;

u will find mysql executes the query is:

SELECT id,name FROM users where 1

just means (id=1 or 5<=5) is same as 1
