FRESH orange juice will go with hot sauce, donuts, OR toast!

Logical processing order (a.k.a. binding order) of a SELECT query in Microsoft SQL Server T-SQL is fundamental.  This is because it has direct bearing on what results (data) you get, which is the whole reason for querying in the first place.  Unfortunately for us, it looks almost nothing like the order we have to remember to use when writing T-SQL syntax.  Keep reading…

Get Microsoft Windows 8.1 installation media (ISO) for offline update or fresh installation

I just found something I thought I should pass along. Sure, it’s only for the desktop OS, but many if not all of us in this line of work use one.

Without setting this up, your options are either A) refer to said machines by IP address only, or B) manually add their hostnames and IPs into DNS, and manually keep those records updated.
