Re: ORA-00604 error when creating a connector to a Oracle DB

This error message comes from Oracle, so it's likely that the problem will have to be resolved at the Oracle side. Often you get a further, more detailed error from Oracle, but this doesn't seem to be the case here.


If you are trying to connect to newly created Oracle tables, this may help:

Re: ORA-00604 error when creating a connector to a Oracle DB

Hi @Anonymous ,

I have made a test on my side, and don't have the issue that you mentioned.


Based on the issue that you mentioned, I think this issue may be related to your Oracle table rather than PowerApps itself.

The ORA-00604 error occurs while processing a recursive SQL statement. A recursive SQL statement is a statement that is applied to internal dictionary tables.

Please check and see if the following blog would help in your scenario:

Do you define a trigger within your Oracle DB or the specific table within your Oracle DB? If yes, please consider take a try to remove the trigger from your Oracle DB or Oracle table, then re-create a connection to your Oracle data source from your app, check if the issue is solved.

Note: Currently, within PowerApps, we could not create a connection to a Oracle data source which has configured Trigger within it.


In addition, you could also consider take a try to re-create a new database within your Oracle, then create a new table within it. Re-create a new app, then create a connection to your new Oracle DB, check if the issue is solved.
