MySQL Pooled queries have the wrong parent about dd-trace-js

[rochdev]

I cannot reproduce this issue specifically since the provided snippet gives me the correct span. I was however able to cause a similar issue related to the internal queue of the mysql module.

@fragglebob If I open a PR, would you be able to try it out directly?

[fragglebob]

The snippet I shared produces the correct span. It's the way I've got round the issue for now.

Sure, I can give it a go tomorrow.

I meant that even without tracer.bind() it still works for me, even if I run multiple queries.

Here's the PR: #178

I get ya now.

I think it might have been from using a combination of express, graphql and mysql together. I will give it a go tomorrow. 👍

If I get some time I will figure out how to cause it in a smaller example.

[fragglebob]

Yep, that fixes it completely.
