Review comment:
Although various tests use different approaches, I recommend removing
the given/when/then comments.

Review comment:
To provide more precision in testing, the `assertThrows()` method
supports indicating the expected exception on the particular method being
called. In addition, should the expected exception be
`SQLFeatureNotSupportedException`?

Review comment:
To avoid unexpected results, passing the column label as a parameteror
using a static variable would be helpful.
