Some additional information - a GUI tool for inspecting sqlite databases
tells me that the following is the CREATE syntax for such a table as I
mention above:
CREATE TABLE "invTypes" (
> "typeID" integer NOT NULL,
> "groupID" integer DEFAULT NULL,
> "typeName" varchar(200) DEFAULT NULL,
> "description" varchar(6000) DEFAULT NULL,
> "mass" double DEFAULT NULL,
> "volume" double DEFAULT NULL,
> "capacity" double DEFAULT NULL,
> "portionSize" integer DEFAULT NULL,
> "raceID" integer DEFAULT NULL,
> "basePrice" decimal(19,4) DEFAULT NULL,
> "published" integer DEFAULT NULL,
> "marketGroupID" integer DEFAULT NULL,
> "chanceOfDuplicating" double DEFAULT NULL,
> PRIMARY KEY ("typeID")

I should stress that I don't know how the interface got this information
other than that it opened the database file.
