Hi,


based on the SQL parser example in Levine et. al. I tried to write a
parser that allows WHERE clause like


      WHERE model LIKE '1J?'


Does anybody has written such a parser in lex/yacc that recognizes
patterns that contain wildcards?


Regards Norbert
[The patterns are just quoted strings. They shouldn't be hard to
lex. -John]
