Yes, thanks
It actually occurred to me soon after my original post that my initial code may not have been doing what I expected. I was going to test that but then I got the reply from [id://tanktalus] and got sidetracked.

Your examples make it perfectly clear, and further demonstrate why it is much better practice to use placeholders and let DBI do all the dirty work.

I'll be sure to remember that in future :)
