i have a database with cross database ownership chaining enabled. data base was detached and reatached as a result owner changed from sa to account that was used during reataching. will this affect chaining?
View 1 RepliesI saw this option in SSMS under "Servers, Property, Security tab". I looked at BOL but I still don't understand what it is or what it is used. Any help appreciated.
TIA,

We are having a problem with cross database ownership chaining. Below is a description of the problem:
I have a domain group named DOM1GROUP1
I have a domain user DOM2USER1 who is a member of DOM1GROUP1 (note that they are in different domains)
I have a database DB1 which contains a stored procedure (st_insertdata) that does an insert in a table (tb_data) on DB2
DOM1GROUP1 has been granted login rights on the SQL Server
DOM1GROUP1 is a user in both DB1 and DB2
DOM1GROUP1 has execute rights on procedure st_insertdata and insert rights on table tb_data.
All objects are owned by the dbo schema.
The database owner for DB1 and DB2 is sa
When DOM1USER1 executes st_insertdata an error is returned:
The server principal "DOM1USER1" is not able to access the database "DB2" under the current security context.
I've played around with the options "trustworthy" and "db chaining" but these do not make any difference. The only thing that fixes this problem is if I create a login for DOM2USER1 and grant it access to DB2 (with no other rights other than membership of the public role).
It seems that SQL Server does not recognize that DOM2USER1 is a user in DB2 by virtue of its membership of the domain group DOM1GROUP1. Is there a way to get this to work without granting explicit rights to DOM2USER1?
I am getting the following error when trying out DB chaining and Ownership chains
Msg 916, Level 14, State 1, Line 1
The server principal "user" is not able to access the database "Test" under the current security context.
I did run these scripts to setup DB Chaining
ALTER DATABASE [Test1] SET DB_CHAINING ON;
ALTER DATABASE [Test] SET DB_CHAINING ON;
I then setup user using a sysadmin role with select permission to a view. The View is on Test1 and points to Test database using a synonymn setup on Test1.
According to all the articles I have read this is all I should do and the view should then run.
i have enable cross database chain,but it return error message:
The server principal "S-1-9-3-1149532189-1170944071-2610337685-3868961652." is not able to access the database "db2" under the current security context.
I list the sql script as follows:
Code Block
use master;
go
create database db1;
create database db2;
go
use db2
go
create table table1
(
col int
)
go
use db1
go
create user u1 without login
go
create proc p1
as
insert into db2.dbo.table1 values(1)
go
grant execute on p1 to u1
execute as user='u1'
exec p1

My system was crashing so I reinstalled everything. including SQL 2005 Express with management studio. I renamed the computer from the previous install. but for some reason the sql 2005 express management studio remembers the old machine name even when I create a new DB inside the management studio with the new computer name.when I try to change the ownership in properties-files it cant find the 'new computer nameuser'i double checked the computer name its correct. The funny thing is i installed express with the 'new computerame' anyone have a clue that may help with this what file needs to be edited?Thanks inadvance for any help.

I have a database called sky and its tables, views, procs and functions owned by sky. I need to replicate the sky database to another server. I had problem because those objects have ownership sky not dbo. I can not change ownership when replicate the database. How do I replicate database objects that are not owned by dbo? Is this possible or I have to change ownership from sky to dbo before replicate the database?
Thank you very much for your input and suggestions.
we have a group of developers which have created and asked us (DBAs) tocreate many objects in the databases including tables / storedprocedures / functions / etc.since our company is growing, however we have an increasing amount ofobjects that have either been abandoned or have several versions.in an effort to clean of the huge amount of clutter and anytime thatsomething simple like a stored proc needs to change, it is almostimpossible to predict exactly where we will see negative effects ofthis change.i am looking for a system (preferably without developing our own tool)that would keep track of history of database objects (in terms of whocreated it and what purpose it has) as well as link that to all thedevelopers/users we might need to notify of any changes to that object.Also, this should be linked to the application which rely on theobject.bottom line... every object in the database needs to have at least 1corresponding contact as well as the applications which us it.with this information, we can much more easily maintain objects in ourDBs.thx
View 3 Replies View RelatedI installed VS2005 on my laptop at the office and of course, got the default instance of SQLEXPRESS. When I take my laptop home and log in (I use my NETWORKlogin login everywhere), I can't authenticate to use the database -- it doesn't like my login unless I'm physically at my office.
So, thinking I'm clever, I changed my SQLEXPRESS instance to use 'SQL Server and Windows Authentication mode' and tried to use the 'sa' login in my connection string. Login failed for 'sa' and since I had never set a password (yes, I tried using a blank) I executed the following query on my db:
exec sp_password @new='WHATEVERPASSWORD', @loginame = 'sa'
The query works (?) but it my connection string doesn't and I'm still unable to use the management tool when not on the original network.
So, I thought I'd add a new, super secret special user, but alas, that has completely escaped me. That frightens me a bit because I'd really like to be able to deploy my database to my web host and trust the my connection strings will work.
So, here are my questions:
1. Can I set up my instance so that I don't have to be on the network on which I installed it in order for it to recognize me (since it's self contained on my machine)? If so, how?
2. How do I create new SQL users?
3. Has the connection string changed significantly, and consequently, am I missing something fundamental in my attempts to connect? If someone could toss out a working SQL Server Express 2005 connection string that doesn't use Windows authentication, that would be really appreciated.
Here's some info from my box, if it helps.
Microsoft SQL Server Management Studio Express 9.00.1399.00
Microsoft Data Access Components (MDAC) 2000.085.1117.00 (xpsp_sp2_rtm.040803-2158)

2005 supports multiple schemas within the same database. Maybe I should logically separate my databases this way? Seems like it would be a tough solution to manage since I already have some databases live in production that will eventually use this 'static' GeoDB. Also, seems like it
wouldn't be as portable as keeping the GeoDB info in its own database,
but maybe I'm being too software engineer-ish here - afraid of low
cohesion, high coupling.I will greatly appreciate any advice I can get, or any more options I am missing. Thanks,Adam Nofsingerucnmedia.com

Hi,
I'm doing a web application that will get some information from an ERP.
At this moment I have 2 databases:
1) The aspnetdb, where I have the tables for Merbership and Role
2) The ERP database
I need to put my web application tables on one of these two DB's. This tables will reference the users from the membership and some products from the ERP DB.
I will store products requests that will store both UserID (from aspnetdb) and ProductID (from ERP DB). I'm thinking to put these tables on the aspnetdb, so that all web application tables stick together. But, I will loose tha ability to make joins with the ERP database, right?
Do you think this will work? Can someone make some comments about this situation, and give me some tips?
Thank you!
I am interested in adding a new row to a table 'Table05' that exists in a SQL Server 2005 database whenever a table 'Table00' in another SQL Server 2000 database has a row added to it. Can someone tell me a way to implement the above solution?

i know that db.owner.tablename works in the query analyzer, but what i really appreciate from anyone is how to apply this in vb6 code since the recordset is opened only from one db using the following syntax:
rs.open "select ...", dbname, ..., adopendynamic, adlockoptimistic ...
thanks
Hi everyone!
I recently found out that using ADO to connect to the SQL server without mentionning the data source; then, by sending a query with the following syntax: dbname.owner.tablename.columnname... an implicit connection to the data source (database) is performed automatically. This way of connecting allowed me to manipulate accross two or more databases thing that is necessary in my project.
My question is:
1- Do anyone have any bad experience and/or negative consequence to such connectivity (memory consumption, unexpected disconnection, ...)? Please consider a very high frequency of manipulation since we are dealing here with a 24/24 hour operational site.
2- Are there any alternative solutions for cross database manipulation (select, insert, update, delete)?
Thanks
As far as I know SQL Server 2005 lists only dependencies within the same database. In many cases though there are objects in one database depending on objects in a different database on the same server. I unsuccessfully looked for a tool to list those and I ended up creating a script to do the job instead. Any improvements are appreciated, e.g. the script uses syscomments which may no longer be available in the next SQL Server version - I have not found a replacement sys.XXX table yet. Please note that you need to use a connection with access to all the SQL databases on a server and that it may take a while to run the script below if you have many databases with numerous objects in there. On the other hand these are exactly the cases when you need to know which of the thousands of objects are dependent on the table or view you are looking at.
P.S. Does anybody know where the extended properties get stored (hint - not in syscomments)? I was looking for those too, since often I document in the description of a field that it links to "DatabaseABC.dbo.TableXYZ.Field1"

I'm not personally a DBA or claim to be a database expert, instead I am a software architect who works closely with database architects and DBA's. I'm presently architecting a system where we will have a smart client used in both Europe and the United States from the same database instance.
The system is to be used for performance testing of devices and then the results will be available to management through the same smart client used by test engineers etc. The first release is operational in the United States today with Poland coming online shortly.
Today we are weighing our options between having cross-geo database mirroring or merely having the database server in the United States with application server level caching implemented in Poland and the United States.
The .net framework's Windows Communication Foundation is used with a netTcpBinding and the service layer is asynchronous with the reliableSession option enabled.
Does anyone have any feedback on whether you would go with cross-geo database mirroring or would you use local application servers with possibly some caching capabilities at that layer? Please also describe the benefits and any risks associated with each also...
Thanks in advance,

Is there anyway to check for cross-database dependencies?
For example:
I have a stored proc in the Pubs database that contains a query that references a table in the Northwind database (as well as reference a table in the Pubs database.) I'm having no problems finding the depencency for the Pubs table. I can't seem to find the dependency for the Northwind table.
Any help would be appreciated.

I have two databases Basket_ODS and Intelligence_ODS.
I created a user in the Basket_ODS and Intelligence_ODS databases as follows:
USE Basket_ods
GO
CREATE MASTER KEY ENCRYPTION BY PASSWORD = '*******'
CREATE USER BasketServiceUser WITHOUT LOGIN
ALTER AUTHORIZATION ON SERVICE::[Order Send] TO BasketServiceUser
GRANT CONTROL ON SERVICE::[Order Send]
TO BasketServiceUser
CREATE CERTIFICATE BasketServiceCertPriv
AUTHORIZATION BasketServiceUser
WITH SUBJECT = 'ForBasketService'
BACKUP CERTIFICATE BasketServiceCertPriv
TO FILE = 'BasketServiceCertPub'
In the other database...
I created the following:
USE Intelligence_ODS
GO
CREATE MASTER KEY ENCRYPTION BY PASSWORD = '************
USE Intelligence_ODS
GO
CREATE USER BasketServiceUser WITHOUT LOGIN
CREATE CERTIFICATE BasketServiceCertPub
AUTHORIZATION BasketServiceUser
FROM FILE = 'BasketServiceCertPub'
My Queue is in BASKET_ODS and is set up as:
ALTER QUEUE ODS.[Order Process Queue] WITH
ACTIVATION (
STATUS = ON,
PROCEDURE_NAME = ODS.ProcessOrderQueue,
MAX_QUEUE_READERS = 4,
EXECUTE AS 'BasketServiceUser'
)
I have performed the following grants in Basket_ODS
grant execute on ODS.ProcessOrderQueue to BasketServiceUser
ProcessOrderQueue calls [ODS].[MoveOrderTotals_Core] in the Intelligence_ODS database.
grant execute on [ODS].[MoveOrderTotals_Core] to BasketServiceUser
ProcessOrderQueue proc is set as follows:
ALTER procedure [ODS].[ProcessOrderQueue]
WITH EXECUTE AS 'BasketServiceUser'
[ODS].[MoveOrderTotals_Core] is set up as follows:
when I run ProcessOrderQueue I get an error message:
ALTER procedure [ODS].[MoveOrderTotals_Core](@Orderid uniqueidentifier)
with execute as 'BasketServiceUser'
I just don't understand when I run ProcessOrderQueue I get the following error message (when database trust is turned off)
The server principal "sa" is not able to access the database "Intelligence_ODS" under the current security context.
Can you help me figure out what I'm doing wrong. I've spent so much time on this security stuff. Is there another way to do this that is more straight forward without using database trust?
This may be a newbie question but...
Say for example DatabaseA has failed over to the mirror. Then you call a stored procedure in that database that queries a table on DatabaseB that is on the principle (has not failed). What happens? Is mirroring smart enough to know that? If not, are there workarounds? Perphaps manually failing over the other databases?
Thanks
Hi all,
Could you please suggest workaround for systems that have cross database queries and want to use mirroring.
Thanks,

Hello,
I want to know how efficient are cross database selects such as
select column from data.dbo.table;
The reason I'm inquiring is because I want to design a database whereas I'm tightly coupling the tables in several databases that are all referencing each other in some way shape or form.
If it is not too efficient or if you know of a way to make these cross database selects more efficient please offer the suggestion.
Thank,

What is the relative performance cost of peforming joins, inserts across databases as opposed to performing them on tables within the same physical database? I can't find much on this at all..
Thanks
Hello All,
I have an issue where my SQL query is taking an exceedingly long time to execute. It joins tables in 2 different databases. When I import the tables from both my databases into a single database and execute the query, it executes instantly!
I had a look at the execution plans of the same query when executed within a single database and the query when executed with tables across databases and there were differences in the execution plan. The single database query had parallelism whereas the query for cross database joins didnt have any parallelism.
Both the databases are in the same server.
I havent seen a case where cross database joins impact query performance so much. Any pointers?
Thanks
Arun
I have an application that segregates data into two differentdatabases. Database A has stored procs that perform joins betweentables in database A and database B. I am thinking that I have reachedthe limits of Application Roles, but correct me if I am wrong.My application creates a connection to database A as 'testuser' withread only access, then executes sp_setapprole to gain read writepermissions. Even then the only way 'testuser' can get data out of thedatabases is via stored procs or views, no access to tables directly.Anyone know of a solution? Here is the error I get:Server: Msg 916, Level 14, State 1, Procedure pr_GetLocationInfo, Line38Server user 'testuser' is not a valid user in database 'DatabaseB'The system user is in fact in database A and B.thanksJason Schaitel
