I am looking for a tool where I just write my SQL Server query and it generate some visual in the form of Venn diagram or any other diagram, so I can understand complex SQL query written by other people. Having a tool to show, visually, or how the query is working. But I have not found such a tool online. Is anyone know any such tool??? Or is there any other way I can understand complex queries???
SQL Server Management Studio (SSMS) has a graphical query view:
I have never found visual tools much good for understanding queries.
It is probably best to get the query into a consistent format, using something like https://poorsql.com/, and then work your way through it with a divide and conquer strategy. The more you do it the better you get.
