SQL code generation from table-free boolean queries?
Given string input such as: foo=5 AND a=6 AND date=now OR date='2013/6' AND bar='hello' I am going to implement: - boolean understanding (which operator takes precendence) - spliting off of attributes into my function which computes their table in the SQL database - piece everything together into an SQL query However, it came to me that this is probably a very generic thing; and there might be a library for it. If that's so, can you recommend it? Thanks! -- http://mail.python.org/mailman/listinfo/python-list

It sounds like you might want to use pyparsing and start with something akin to this[1] -tkc [1] http://pyparsing.wikispaces.com/file/view/simpleSQL.py -- http://mail.python.org/mailman/listinfo/python-list
