Not an online tutorial, but a book (though it comes with a CD which includes a searchable electronic version of the entire book text), which I cannot recommend highly enough: Inside SQL Server 2000, by Kalen Delaney. http://www.microsoft.com/mspress/books/4297.asp (disclaimer: I've actually only read the SQL Server 7.0 version, but I can only assume the 2000 one is as good) Gives you a great deal of insight into the internal workings of SQL Server at an intermediate level. Good for moving beyond 'beginner' stages. (of coure, if you're going to buy it online, you should support evolt.org as you do so: http://amazon.com/exec/obidos/ASIN/0735609985/ref=nosim/evoltorg02-20) And don't forget the SQL Server Books Online, which are optionally installed as part of a SQL Server Installation. Very helpful, if a little dry. Cheers, Paul.
