I have a table EMPLOYEE in database PERSONNEL, and a table JOBS in database JOBMAN, I want to create a dependencies on the primary key EMP_NUM in table EMPLOYEE and the foreign key EMP_NUM in table JOBS, how can I do it in Enterprise Manager or any other tools?
View 5 RepliesAs 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"

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?
How do you write a SQL SELECT statement for a cross-database query in ASP.NET (ADO.NET). I understand the server.database.owner.table structure, but the command runs under a connection. How do I run a query under two connections?
View 1 Replies View RelatedHi,
I'm trying to get data from several databses of different kinds (Sql Server and Oracle) and from different servers - is that possible ?
If not - is there any way to copy some data from one database to another - like tables and their content (or partial content) ?
I tried to use "select name from <database name>..sysobjects where xtype = 'U'" but I get security error.
thanks,

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
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,

in oracle we can connect via one user
and can select the tables of another user.

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.
Thanks in advance.

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.

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
View 4 Replies View RelatedWe're trying to follow the principle of least privilege here in setting up a user account for our website to use to access SQL Server 2005, but we're having a nightmarish time getting it to work.
The issue seems to be trying to get a limited access user account the ability to cross databases.
Here's the situation:
We have a User [WebUser] that we want to grant access to the database. This account has a login [WebUser] that has username=WebUser and password=ALongPassword.
This user only calls stored procedures in the database [WebData].
However, some of the stored procedures in [WebData] call stored procedures in the database [dbutil].
One of the stored procedures in [dbutil] inserts records into a table in a third database [dbutil_temp].[DebugLog].
This all works out great from my development account using Windows Authentication.
But as you might guess, if I do something like "EXECUTE AS [WebUser]" and run the same procedure on [WebData] things fall apart quickly. I've looked online regarding cross-database ownership chaining, but quite frankly, the whole users/logins/roles/schemas security model is confusing, and I'm getting nowhere fast on my own.
We really only want [WebUser] to have CONNECT and EXECUTE permissions on the primary [WebData] database, but it seems like we've got to do a lot more than that to get this to work.
I'd appreciate any help...
I have noticed rather strange behaviour of EXECUTE AS and REVERT sequence during the cross database calls which appear to be a bug. I tested this issue on developer edition of SQL Server 2012
Microsoft SQL Server 2012 - 11.0.5343.0 (X64)
May 4 2015 19:11:32
Copyright (c) Microsoft Corporation
Developer Edition (64-bit) on Windows NT 6.1 <X64> (Build 7601: Service Pack 1)
This issue causes problems in SSISDB where similar piece of code appears in [catalog].[start_execution] and some other scripts in the [internal] schema. This was previous discussed in [URL] The following script illustrates the issue:
USE [master]
GO
CREATE DATABASE [Test1]
GO
CREATE DATABASE [Test2]
GO
-- Set Database to Trustworthy to allow cross database connection
ALTER DATABASE [Test1] SET TRUSTWORTHY ON;
GO
ALTER DATABASE [Test2] SET TRUSTWORTHY ON;
GO
USE [Test2]
GO
CREATE PROCEDURE [dbo].[TestContext]
AS
SELECT 'EXECUTION CONTEXT BEFORE EXECUTE AS CALLER', SUSER_NAME(), USER_NAME();
[code]....
We maintain a few applications that query multiple databases on our server. We also have groups of users that multitask using different applications.
I've always created a Role in each database for every application.
Wondering if someone is in two Roles at once will we have security conflicts?
Can someone give me an example on how to enforce cross-database referential integrity with triggers in SQL Server 2000?
Thanks,
Joel
