By no mean is this a MySQL forum only, so feel free to ask any questions about any flavour of databases!
Also, don't post questions where databases are only slightly involved and the actual problem is about the server-side language that interacts with the dB.
This forum is more for questions about the actual query language, meaning, queries, structure, syntax, etc..
(Admins feel free to delete this post if you feel like you should be the first ones to post )
this is important to us because different database vendors and versions have different features. lots of them have stored procedures. sql server and mysql support limited results returned in a query. oracle supports more advanced queries like hierarchical sql (allows you to have a table that references itself and you can select the tree of rows starting with a particular id)
also try to avoid making posts like "i tried installing SQL and ..." as that doesn't make sense. SQL is a language, like swahili and cobol, you can't really install it, you can learn it. you can install a server that understands SQL, if so tell us the version and type.
I just want to reiterate this point - Most DBMS adhere to the generic ANSI standard, but not strictly. The standard doesn't have everything needed, and each vendor has provided their own syntax for creating what is needed.
