I am on the same page, however I wanted to bold it out since it can cause issues. test is just really far on the argument side, so it's easy to miss. I think @mosabua suggestion is best resolution:

make more explicit in the sample code

[mfzarko]

Done, does it look ok now?

[mosabua]

I think you should update all the sql queries accordingly

[mfzarko]
