derby database source code.good for you.

-- this test is for identifiers and delimited idenifiers
-- identifiers get converted to upper case
-- delimited identifiers have their surrounding double quotes removed and
-- any pair of adjacent double quotes is converted to a single double quote
-- max identifier length is 128

-- trailing blank not trimmed
