Answer 1

The official answer according to IANA is application/sql. See http://www.iana.org/assignments/media-types/media-types.xhtml and http://tools.ietf.org/html/rfc6922

However, since lots of people don't bother to read documentation you might also want to accept text/sql, text/x-sql and text/plain.
