“sys2” scripts are growing

I’ve just released a new script, and now the sys2 scripts are reached the double-digit number: 10!

http://sys2dmvs.codeplex.com/

The latest addition is the sys2.tables_columns scripts that helps me to detect which tables uses LOB column so that I can also check if that LOB data resides on a dedicated filegroup or not. Usually when I have such situations and the LOB data is seldom accessed (say, 1 time each dozens of requests) I create a specific filegroup and use that for LOB data, so that the standard data pages will only hold a 16byte pointer to that data, helping to keep data pages dense and thus extremely efficient from a caching and (read) I/O access point of view.
