SQL Language server

Many developers are also using relational databases in their applications and using SQL statements in their code and/or writing database migration scripts. I think it could be useful to add some sort of SQL language server to WildWebDeveloper.

While things like Data Tools Platform and DBeaver exist, the former is "in maintenance mode" while the latter is more or less its own product and there might be people who don't want to have DBeaver in their IDE.

While there are many SQL dialects, maybe there are some general language servers for core SQL (ISO/IEC 9075).

The main reason I'm suggesting this is that I'm experimenting with lsp4e (hoping to be able to contribute it at some point) to add (some) language server support to Java text blocks (currently only completion).

Non sono indicati file sorgente, test o punti di ingresso concreti. Inizia esaminando la motivazione dell’issue e la pull request di lsp4e collegata, quindi determina l’ambito SQL supportato e come il supporto per i language server si integrerebbe con WildWebDeveloper; il lavoro è completo quando è stata concordata una direzione di implementazione, non con una modifica isolata.
