[ how to parse embedded SQL without tripping over SQL keyworks in
non-SQL code ]
The easiest way to achieve this, IMHO, is to introduce feedback from
the parser to the lexer. When the parser recognizes the beginning of
an sql statement, it sets a lexer flag saying "give me sql keywords
now". Flex has this builtin, it's called "start states". Even if you
don't use flex, read its doc to get some ideas.
