Yes, the structure of this table goes back to foxbase days.
There was no tinyint there.
The structure has changed occasionally over the years (multiple decades now).
It's a key table, used all day, every day, but it's read tens of thousands of times more than it's written.
We also now have a read-only mysql version- synched from the SQL version- of it going with a PHP web site.

I didn't see Naomi's latest version of the query but it sounds as if it might be the answer.
I'll try it.

There are no nulls in table
