Help With ORA-01436: CONNECT BY loop in user data
I'm not sure if anyone here will be able to help me or not - but recently 'something' seems to have happened to the database here (Oracle 11g I believe).
Now this 'ORA-01436: CONNECT BY loop in user data' error is popping up all over the place. I've Googled on the error and I understand that people get it when they execute a circular query that results in a 'loop'.
The problem is that I'm getting this error in places I wouldn't expect. For example, I use SQL Navigator 5.5 and when I log in it shows an error in the Output window that says, '9:56:29 AM Error initializing Team Coding: ORA-01436: CONNECT BY loop in user data'
I'm also using a 3rd party tool (Active Query Builder) that generates .xml metadata file - no updates or patches were made to change how that application works but now it fails with an OracleException that says, '9:56:29 AM Error initializing Team Coding: ORA-01436: CONNECT BY loop in user data'
I've been told that Visio also produces a similar error.
Does anyone have any idea what I can do to troubleshoot this? Is there a system table that gets queried when a user logs in that might have a loop in it? We have other DB instances that are Oracle 11g as well and they are still fine.
Any suggestions or advice is greatly appreciated.
Thanks!
