Okay, I created this table (InterBase 6.01):
create table PV_TEST
ID integer not null,
PT_TEST_ID integer not null,
FLOATVALUE double precision,
TEXTVALUE blob sub_type text segment size 80,
PERSISTENTVALUE blob segment size 80
This is what I got from a cursor's description:
(('ID', <type 'int'>, 12, 4, 0, 0, False), ('PT_TEST_ID', <type 'int'>,
12, 4, 0, 0, False), ('INTVALUE', <type 'int'>, 12, 4, 0, 0, True),
('BOOLVALUE', <type 'int'>, 12, 4, 0, 0, True), ('FLOATVALUE', <type
'float'>, 17, 8, 0, 0, True), ('DATETIMEVALUE', <type 'tuple'>, 22, 8,
0, 0, True), ('DATEVALUE', <type 'tuple'>, 22, 8, 0, 0, True),
('TIMEVALUE', <type 'tuple'>, 22, 8, 0, 0, True), ('TEXTVALUE', <type
'str'>, 0, 8, 0, 1, True), ('PERSISTENTVALUE', <type 'str'>, 0, 8, 0, 0,
The tuple type is really a tuple. Try this:
This will give you a tuple. Well, you can ask for a separate DATE and
Well, in dialect 1, only TIMESTAMP supported.
