DB-link is not connected from Forms 10g

Question

Hi,
I have created the db-link(visdev) from mytest schema to APPS schema -- created successfully
->Login to mytest schema and ran the query: select * from all_objects@dblink -- Return values.
-> I have used the same dblink with below code from Forms 10g (Datablock - Pre-insert trigger)
cursor_handle := dbms_sql.open_cursor;
dbms_sql.parse(cursor_handle, 'select decode(object_type,''TABLE'',''T'',''VIEW'',''V'',null) col1 from all_objects'||'@'||db-link, 1);
dbms_sql.define_column(cursor_handle,1,col1,30);
execute_feedback := dbms_sql.execute (cursor_handle);
execute_feedback := dbms_sql.fetch_rows(cursor_handle);
dbms_sql.column_value(cursor_handle,1,col1);
Its throws error in Pre-insert trigger : select decode(object_type,'TABLE','T','VIEW','V',null) col1 from all_objects@db-link ---- Not return values -- error out
I found this error using log message.
Can you please help us... its very critical for us.

Answer 1

In terms of trying to debug this why don't you login to your schema and create a view:
create view testview as select * from all_objects@dblink
and deal with that instead?
(You would need to grant permissions to that view.)
I mean as a way to keep the complex dbms_sql out of the loop and look
more to permissions and schema issues. In the long term the view hard codes the structure and is
not a good solution if the structure changes. I just mean as a test.
BTW you know there is an all_objects already? Didn't know if you meant that literally or not.
You could not use that name.
