The getFields thing came up because the sqlite cursor doesn't fill

So I thought about using getFields to return the Field information for
SQLite.
The 'setDefaults()' call doesn't use data types; instead, it is
simply a dictionary with field names and default values that allows the
developer to set default values for some fields in new records. There is
a bizobj attribute 'defaultValues' that is the dictionary passed to
setDefaults() (see line 94 of the SimpleFormWithBizobj.py demo script
for a sample usage).
I'm looking into the getFields() situation, but I gotta go take my
kid somewhere now. I'll look at it in more depth tonight.
I gathered that setDefaults doesn't need datatype but it uses the
Fieldnames from Fielddescription
which is an empty dictionary in the SQLite case.
Basically what I need to get SQLite working, is a way to get a list a
field names for a give table,
since empty SQL statements return an empty description.
