I talked to Christopher Jones (of Oracle fame) and Lorenzo (MDB2
maintainer). Its clear that the only named parameter supporting
database I know does not support dash inside named parameters. Its
also dangerous since it means that whitespace typos could have
serious hard to spot issues. I think a safe regexp for bound
parameters would look something like: /^[a-z0-9][a-z0-9_]{0,30}$/
Since I couldn't find any official reference in
the oracle documentation, I did further tests.

so please someone revert this change ... or better yet implement the
above rules.
I won't like having vendor specific rules there but a subset which works
with most/all backends and which should full-fill most user's needs. The
regexp from above looks like a good compromise for me.
This one is safer:
/^((?:\d+)|(?:[a-z][a-z0-9_]*))$/i
or better yet:
/^((?:\d+)|(?:[a-z][a-z0-9_]{0,29}))$/i
