Simple python SQL parser based on PLY library https://github.com/dabeaz/ply/

By design, this is parser for make statistic information about SQL query, what and from is selected. Parser may return a little bit incorrect outputs - this is ok. :)

Parser has not based on any SQL dialect (i use PostgreSQL and Firebird and you may think what this parser based on they).

Todo: -Use database scheme to define aligment fields to tables. (in another project :) ) -group by/having -order by -cast(blah as blah), exists(SELECT) -maybe: substrings (firebird 2.1 form)
