Is there a tool (gratis), that helps developer to understand or helps to visualize the complex queries (involving JOINS, GROUP BY).

I know about the snowflakesjoins service which provides visualizer upto 800 characters but that is quite short.

It doesn't really matter if it can access the database or not. All I want is: if the SQL query is supplied, it should give some sort of visualization to understand the complexity.

I am looking for something that runs on Windows.

This online SQL parser visualises data flows and table joins in SQL statements -- see demo. It comes with a free tier.

disclaimer: I am co-founder of SQLdep (somebody who got too lazy to manually analyse SQL) :)

  • Well, the tool looks good but it seems like heavily priced for anyone even to consider.

    QueryScope (query visualiser) is $15/month. QueryFlow is heavily priced as it aims at DWH teams with 1m+ lines of SQL code. Aug 9, 2017 at 16:03
