Hello,
I am trying to do a schema export on 8i (exp system/***@dbname file=xyz.dmp log=xyz.log owner=xyz), but the export ends with the following error:
. exporting views
EXP-00056: ORACLE error 1436 encountered
ORA-01436: CONNECT BY loop in user data
EXP-00000: Export terminated unsuccessfully
This error occurs while exporting the views. The tables are exported successfully.
On MOS, I found DocID 6936881.8, which states that this is caused by 2 views with foreign keys that cross-reference each other and the solution is to disable those contraints.
First of all, is it even possible to have primary and foreign keys directly on views???
And how can I find the views with foreign keys that cross-reference each other? Does anyone have some sort of query for this?
Could it be that the foreign keys that cross-reference each other are actually on the tables? Coz from dba_contraints, I haven't seen any views with pk's and fk's.
In this case, I would expect the export of the tables to give the error message, not the export of the views...
Is there another way to solve this export problem?
Thanks in advance.

What I would try is to re-compile the views and see if the error shows up during that.
You can run
SELECT 'alter view ' || view_name || ' compile;' FROM user_views;
as user xyz and then run the resulting script to compile them all.
