Question

What is wrong here?

SELECT u.id
FROM user u
LEFT JOIN group g ON g.id=u.group_id

The following error is returned

#1064 - You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to
use near 'group g ON g.id=u.group_id LIMIT 0, 30' at line 3

Answer 1

GROUP is a reserved word in the SQL standard due to the GROUP BY clause. Even Stack Overflow highlights it with blue 😉

If you want to use group as an identifier, you must quote it like this:

`group`

You may also rename the table to something more meaningful, like UserGroup. That will solve your issue as well.
