Please kindly squash your commits together. If you don't, we'll try to remember to do it for you but it's best if you save us this trouble.

How to do that?

1. git rebase -i origin/3.1.x, assuming origin is a git remote that points to this repository, and not your fork. If you're not sure what your remotes are, run git remote -vvv, there should be your fork and the holy/reference/base/origin/whatever-you-call-it repository.
2. A window will show up with many lines, replace pick with fixup on every line but the first one
3. Close your editor, git should do its magic, and you should end up with one commit
4. Use git push --force to overwrite what you already push. Don't forget the --force option otherwise git will try to merge both things together.

Also, once you have a single commit, please improve your commit message according to the contributing guide. "Discriminator value could be an integer (TypeError is raised)" is not enough IMO.

@greg0ire I think I'm done.

Thanks @prohalexey !

Hello @greg0ire , if it is supposed to be possible to use an integer as a descriminator, in the SqlWalker.php file in line 2255 shouldn't the discriminator be cast to string so that quote() accepts it?

I think so yeah… my IDE prints a warning, but I'm not sure why static analysis does not report it. @prohalexey what do you think?

I ran tests(GH11341Test, GH11199Test) and did not stop at this line (I set breakpoint at 2255). Trying to understand what conditions we must have to call this function getChildDiscriminatorsFromClassMetadata

Yep, I confirm that there is a bug if you make DQL query with INSTANCEOF function. I will create a new PR. @greg0ire
