How do I remove a modded civ's standard units in SQL?

[spilo]

I am editing the mod file RussiaPutin_Gamedefines.sql of JFD's Putin civ mod.

I have been trying to delete the UnitType in the UnitOverrides column, since simply leaving UnitType blank removes units for XML-based civ code. But it doesn't seem to work here (see attached)

I want to disable this civ's ability to produce battleships, triplanes, fighters, etc.

How should I do it?

try 'NULL' instead of ''

or try breaking the SQL insert into two pieces, one where you specify actual UU replacements, and a second where you do not even state column UnitType or any values for it where you want to not allow the civ to use units from within that class.

NULL worked! yay.
