I hate to burst your bubble, but what's wrong with using the DB_EXISTS
dialplan function?
exten => 1234,1,Set(EMAILADDR=
${IF($[${DB_EXISTS(x/y)}]?${DB_RESULT}:[EMAIL PROTECTED])})
Obviously it's a little harder to read (especially when all placed on
one line), but it's already quite easy to use without adding more code
to Asterisk.
