2/2] Distance measure implementation (#1527) * Added distance measure calculation * code refactor * minor fixes * removed database data from constant.py * bug fixes * refactor * improved code logic and added comments * integrated distance measurement to the sql checker * improved duplicate flagging logic * chore(sql-checker): remove __pycache__ * only the closest distance gets saved on the database now * Subqueries and "AND","OR" operators work * Fixed lint problems and started implementing LIKE, BETWEEN, IN support * style(sql-distance-checker): fix style * chore(sql-checker): fix pylint errors * refactor(sql-checker): apply ioc and add tests * feat(sql-checker): add distances to checker output * feat(sql-checker): reimplement query comparision * fix(sql-checker): fix query learning * fix(sql-parser): fix different query lengths * feat(sql-checker): add error depth * style(sql-checker): fix style * chore(sql-checker): remove print * feat(sql-checker): divide distance by 50 and round * feat(sql-checker): improve feedback * feat(sql-checker): make distance disableable * fix(sql-checker): move mongomock into dev dependencies * ci(python): install all dependencies for testing * ci(python): update to python 3.11 * ci(python): update other to python 3.11 * ci(python): fix unittests --------- Co-authored-by: Jonas Kuche Co-authored-by: chrastlet ---
