When 12.2 is released, you'll get a newer version included with your client at least. Then you can upgrade your SQLDev...that's like more than several years old.
Thank you Jeff.
I the last few hours i have some progress fixing my scripts to make them work with older SQL Dev 3.2. (which is our corporate standard for now for supporting personnel)
It appears that the issue with SQL Dev 3.2, UDRs with style "PL/SQL DBMS Output" is this:
- it does not like any comment code lines that have dashes (-----) and it does not like any blank lines.
Hope this may help others if they are running into the same issue with the older version of SQL Dev.
(not sure though if this finding does make any sense for Jeff and his team, but this is what i am clearly observing with my scripts: just remove all comments and blank lines and the error message "Missing IN or OUT parameter at index: 1" goes away )
