Good day, dear people!
In general, soon I will have to study SQL queries very closely, please advise books / manuals, where do I start this business?
I have not been in this area for a long time, I need a certain IDE to write a request and it graphically shows that I’ve been there (tables, connections, views, etc.) - is there such a thing? If so, which one is better? (paid / free - does not make a difference)
For earlier thanks for the advice :)
