Another script, another day. And as promised, I am providing an update to the Table Space script that followed the sp_MStableSpace script. Not a lot more to be said about this one, since much was said already.
I updated the script for those CS collations. I also provided the update to show the % of DB column to be driven based on the data file usage information.

ENDPhew, I finally took care of some of those somedays that have been nagging me. Sure, there has been a someday that has evolved due to that – but that is a good thing.
It helps that I also need these scripts to be CS. Add to that, that I need to use them more frequently and it was a perfect opportunity to do a little housecleaning.
