Works just like a DDS keyed logical with an explicit column list.

Or almost like....

The exception is that with a SQL index, the key column(s) are always at the
beginning. Whereas a DDS keyed logical, the columns can be anywhere.

So you can't replace a DDS keyed logical with one without recompiling
unless the logical's key fields happen to be at the beginning.
