Ugh. I was afraid you were going to say that...
Seriously, there's no way to just 'wildcard' ALL indexes, someone should add
that as a feature request. We're using 4.0.17 BTW.
What happens if I list out all the indexes that there _could_ be in one
ALTER line like that, and one of the indexes doesn't actually exist? Will
the whole ALTER fail?
Here's the situation, I wrote a script that runs recursively through a
directory and applies all the .sql files it finds (in alpha order). This
script runs as part of a client update, and doesn't necessarily run the same
number of times for everyone. So, some clients may have extra indexes:
foo_1, foo_2, foo_3, ... foo_15 etc. (the problem at hand), and other
clients may just have: foo_1, foo_2, foo_3.
