I don't understand why this is happening, because it was my impression that the template parameter substitution happens before the extension is invoked...

Parameters don't work with tag extensions (<tags>). Call as {{#tag: sql2wiki | database=EcoReality | SELECT * FROM mw_user WHERE user_id = {{{1}}} }}

Beautiful! Thanks!

I had been to that page, but somehow overlooked the obvious admonition that one cannot do what I wanted to do.

I did find that the named actual parameter had to be last for some reason. It was being interpreted as SQL otherwise. So this is what ended up working:

{{#tag: sql2wiki | SELECT * FROM mw_user WHERE user_id = {{{1}}} | database=EcoReality }}

Thanks again for your help, Platonides!
