>The sp_database procedure will return the name and size for each DB on the server (to which the user has access). I have several servers, and would like to get not only the name and size of each DB on each server, but would like the DataSize, DataFreeSpace, LogSize and LogFreeSpace. I would like to run a procedure to get/update the latest data on a regular basis.
