Here is the next problem. For boolean/logical fields, I can set their
value to True/False easily. However, setting NULL seems impossible:
rec = tbl.newRecord()
rec["SOMEFIELD1"] = True # Works fine
rec["SOMEFIELD2"] = False # Works fine
rec["SOMEFIELD3"] = None # Will store False
rec["SOMEFIELD3"] = 0 # Will store False
rec["SOMEFIELD3"] = "" # Will store False
rec["SOMEFIELD3"] = chr(32) # Will store False
rec["SOMEFIELD3"] = chr(0) # Will store False
rec.store()
Strange thing: if I do not set the value of a numeric field, it becomes
NULL. The same thing I cannot do for logical fields: if I do not set the
value of a logical field, it becomes an invalid value, denoted with a
question mark.
Have you tried -1?
Can you read a DBF file created by the application (dBase, or whatever)
and see what it uses?
