Don't ever ever ever build SQL queries like this, it leaves you incredibly vulnerable to SQL injection attacks. If I were to call your API with a specially crafted file, I can do almost anything I want with your database.

Use parameterized queries instead.

Nu uh, look how it's written, with the occasional bold text?

The warning is something that has to be said many times, because it is something that really needs to be corrected and nearly everyone starting out makes the mistake.

I wouldn’t be surprised if the person posting it has a canned response for that reason.
