Is the problem here that you have created your tables to have columns that
are specified "NOT NULL WITH DEFAULT"?  If you use interactive SQL to
create tables, for example, the tables are created with this default.  This
will make it impossible to ever get a null value into the database table.
When you pass in null, the default value goes into the column instead of
the null.

If checking into this doesn't help, I can post JDBC examples setting
database columns to null and getting the null value back out if that would
help.

Subject:  Database I/O






Can anyone give me examples of doing direct database IO's on the AS/400 via
Java?  My problem is populating a file that has a null capable field.
Everytime
I try to put a null into this field via a JDBC connection using SQL the
AS/400
places a '0' into it.  When I then run the application it errors out
because it
is expecting a null value.  I was really hoping by doing direct database
connection would solve this problem.  Any help would be greatly
appreciated.
Thank You
