Обсуждение: Some troubles with Access and bool

I have a small table in my 7.4 Postgres database:

CREATE TABLE jmbool
(
 icompt int4,
 mybool bool
)
WITHOUT OIDS;

I have MS Access 2003. My ODBC Driver a the option "treats bool as
char" unchecked.
IN MS Access, I can add a record but it not possible to delete any record:
error message: The Microsoft Jet database engine stopped the process
because you and another user are attempting to change the same data at
the same time.

Of course, I am alone on the Postgres database.
How to solve this blocking issue ?
Thanks for your answers.

Yeah, my problem is solved :-)
With the help of the odbc file log, I have got the request sent to the
Postgres database.
So, the request is:
DELETE from jmbool where  icompt=23 and mybool='0';
but unfortunatly, value of mybool was null and not false because never
initalized.

Access read a value null for a bool type and interprets as false.
the DELETE was denied because not succesfull and Acess says that
another user has changed the record !!!!
Now, the field myboll has a default value as false, all the database
is upgraded  and all works fine :-)
