I'm totally new in this area please tell me how to fix my problem.
when I write this query "SELECT * FROM places
" in my database everything is okay.
However when I change it to "SELECT * FROM places WHERE eventId=2
", I get error. Please look at this image.

as you can see, eventId
column is exist. Why my query throws error?
