Chapter 5: Creating and Altering Tables
Next comes the compatibility level. This will control whether certain SQL Server 2008 syntax and keywords
are supported or not. As you might expect from the name of this setting, the goal is to allow you
to rollback to keywords and functional behavior that more closely matches older versions if your particular
application happens to need that. For example, as you roll it back to earlier versions, some words
that are keywords in later versions revert to being treated as non-keywords, and certain behaviors that
have had their defaults changed in recent releases will revert to the older default.
The remaining properties will vary from install to install, but work as I described them earlier in the chapter.
OK, given that the other settings are pretty much standard fare compared with what we saw earlier in
the chapter, let’s go ahead and try it out. Click OK and, after a brief pause to actually create the database,
you’ll see it added to the tree.
Now expand the tree to show the various items underneath the Accounting node, and select the Database
Diagrams node. Right-click it, and you’ll get a dialog indicating that the database is missing some
objects it needs to support database diagramming, as shown in Figure 5-4. Click Yes.
Note that you should only see this the first time a diagram is being created for that database. SQL
Server keeps track of diagrams inside special tables that it only creates in your database if you are going
to actually create a diagram that will use them.
