Hi Alexy

I have tried to reproduce this, but it all seems to be workiong well for me.
Can you please give me exact details of what priveledges your user has, or provide me with a DDL script of your user so I can try to reproduce the issue.

Regards

It happens on when I try to open one pretty big package. Does not happen when I try to open the same package on another database.

I ran SQL Nav in debug mode under WinDBG, here’s the exception analysis, maybe it will help you guys.

Thanks Alexey for sending the info.

We are still working on this but could not make much progress yet. We will keep you posted…

Thanks and regards,
Bruce

This was a known issue in older versions of SQL Navigator (< 6.x) which is regularly caused by missing recursive grants within multiple database Schemas.

Solution:

  1. Open the package using another IDE for database administration (Ex: Oracle SQL Developer).

  2. Remember the last change you have done (Ex: Using a variable or parameter having a developer defined TYPE) and erase the last change to check whether package opens in navigator after erasing the particular known piece of code.

  3. Move to the Schema where the found TYPE is defined.

  4. Make sure you have given Grants (EXECUTE, DEBUG) for both the TYPE and the TYPE Table to the referring Schema.

Ex:

objCustomerList is a TYPE object created in Schema1.

objCustomerListTab is a TYPE Table of objCustomerList TYPE created in Schema1.

GRANT EXECUTE ON objCustomerList TO Schema2

/

GRANT DEBUG ON objCustomerList TO Schema2

/

GRANT EXECUTE ON objCustomerListTab TO Schema2

/

GRANT DEBUG ON objCustomerListTab TO Schema2

/

  1. You will face this issue when the above recursive Grant (RED COLORED) is not given to the other Schema.

  2. You can redo the changes done to the package after applying corresponding Grants.

  3. Then the package can be re-opened in SQL Navigator. Good luck.!!!

Thanks & Regards,
