Thanks for the patch.

Here is one comment:

The second query has a condition 'WHERE slot_name IS NOT NULL', but I
think it belongs to the first query. Because the slot_name of second query
is built by CONCAT() which means it should be valid, while the first query's
subslotname could be NULL if user executed ALTER SUB SET (slot_name = NONE).

Apart from above, it looks good to me.
