I suppose you could use SHOW GRANTS.


It would require doing some parsing of the output, though, and it
sounds like you may be doing grants on individual columns. Stored
procedures might not be a bad idea either for fine-grained access


O'Reilly has a book coming out soon on MySQL Stored Procedures which I
think is pretty good (I was asked to review the Python stuff but have
no financial interest in it).

The Pythonic Principle: Python works the way it does
because if it didn't, it wouldn't be Python.
