Error:

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 'when) VALUES ('3', 'kiado', 'lakas', '1'' at line 1

Answer 1

WHEN is a reserved word . Enclosing it in backticks should fix your problem, as it will then be treated as an identifier .

`when`

Answer 2

You should use backticks around your column names. when is a MySQL keyword so it's being interpreted incorrectly. At the very least use backticks around when .
