Hi Thomas. Interesting question. A few notes:

Most importantly, there is a typo in the setup code, implying that the answer should be the opposite of what it really is. In the part where you state that you are going to set the test database to "partial containment", your SQL statement actually sets it to its current state of "none". You have:
```
ALTER DATABASE [test_cont] SET CONTAINMENT = NONE WITH NO_WAIT
```
when it should be:
```
ALTER DATABASE [test_cont] SET CONTAINMENT = PARTIAL WITH NO_WAIT;
```
Changing this would have the T-SQL match the text description of what's going on.
Official documentation is here:Contained Database Collations
Minor point, but your initial setup code block could be simplified to be just the following:
```
CREATE DATABASE [test_cont]
    CONTAINMENT = NONE
    COLLATE Latin1_General_CI_AS_KS;
```
or even just the following, since "NONE" is the default for containment type anyway:
```
CREATE DATABASE [test_cont]
    COLLATE Latin1_General_CI_AS_KS;
```

Take care,

Solomon....

Nice question ,thanks Thomas.

Concur with Solomon about the slight mix-up

"

ALTER DATABASE [test_cont] SET CONTAINMENT = NONE WITH NO_WAIT

when it should be:

ALTER DATABASE [test_cont] SET CONTAINMENT = PARTIAL WITH NO_WAIT;

"
