Subj:   Re: DBC AccessRights table is skewed
From:   Roth, David W

I guess my first question is why do you believe the skew on this dictionary table is an issue? Skew by itself is not necessarily bad.

Most times, performance issues with accessrights comes from unneeded rows. Have you tried running the standard cleanup script (attached below) to see what that does for you?



                 WHEN AccessRight='AE'  THEN 'ALTER EXTERNAL PROCEDURE'
                 WHEN AccessRight='AF'  THEN 'ALTER FUNCTION'
