db_owner's permission

Posted on 2004-08-10

A user is in db_owner role.  But she cannot delete a record in a table.  So I explicitly grant her the delete previldge in the table via enterprise manager.  Nothing changes.

Please advise why.

A db_owner does not need explicit permission to delete a record in the table.  Something else must be causing the error, possibly:

1) Connected to a different server & db by mistake
2) Connected to a different db by mistake
3) Error in connection
4) Error in application/interface

Perhaps the public role has an explicit deny.

good answers.  I would also check the table for triggers.  I would also run SQL Profiler and watch what happens.  You should try logging in as the user in Query Analzyer and running the delete.  You'll usually get a good error message there

I ran the following query in Query Analyzer

DELETE  FROM  dbo.tbl1  WHERE     (Id = N'000000000')

Error Msg was

Server: Msg 229, Level 14, State 5, Line 1
DELETE permission denied on object 'tbl1', database 'xxx', owner 'dbo'.

I tried SQL Profiler but I did not know what the trace needs to record.  

Public role is not issue.  

What should I pay attention to about -FK PK

Suggestion of public just an example. Are there any explicit denies at all?

> What should I pay attention to about -FK PK
You can't delete a PK whilst there's a FK to it. Basic database integrity. But the error message doesn't indicate this.

I think you get it.  There is another role which has explicit denies on delete.  I have not tested it yet as I cannot log in as the person now.

?  If you're 'sa' you can test their permissions without actually logging in as that user.

Yes I have the system roles - System Administrators.  I also find out the sa login if I really want to.  Do I have to use 'sa'?  And how should I test their permissions?

The person came back and it worked.

But I still love to get help on 'test their permission withou acutually loggin in as that user'.

Go into Query Analyzer and issue this command:

SETUSER 'optionalDomain/userYouWantToSimulate'

Then any commands you issue will use the permissions of that user.

To reset back to your sa user, do this:

SETUSER  --[with no params]
