bigger problem

in postgres database i created a table with a field like

create table (...)
(...)
var text default '' not null
(...)

now i need to import the data from this table into a oracle database
i used pg_dump

I altered the field data type to

(...)
var varchar2(50) default '' not null
(...)

but when i was importing the the table into the oracle database all the rows
with the field var='' were not inserted.
Is there a way to work this around

thanks for your time and replay

This is a problem with your configuration of Oracle import. See your
Oracle documentation; we cannot help you here.

Yes, don't use Oracle.

In Oracle, '' is the same as null, so the constraint is not satisfied.
