 Description  « Hide
SFID: 567931#
Submitted By: ded

  ANY user can drop procedures, generators, exceptions.
Tables, indices and triggers are not affected. To
reproduce:

1. Connect as SYSDBA
2. Create Procedure Test As Begin Exit; End
3. Disconnect and connect as any user
4. Drop Procedure Test - successfully.

  Interesting is the next: if before step 4 try to

Execute Procedure Test

exception 551 will be raised and after it step 4 will
raise expected exception 607 - unsuccessful metadata
update -ERASE RDB$PROCEDURES failed -no permission for
delete access to PROCEDURE TEST.

Confirmed on builds WI-V1.0.0.794, LI-V6.2.796.

Best regards, Alexander V.Nevsky.

Generators and exceptions don't have an owner, hence the
issue. But this shouldn't be the case for procedures. Needs
checking.
