SQL Server 2005 Schema
Sep 27, 2006
A database was created in SQL 2000. We are going to move to sql 2005. So I attached a database to SQL 2005 and now I have a problem with name resolution. When I worked with SQL 2000 I did not put my schema's name before table name (select * from table1). The schema's name is my user name (IQA) and by default the schema name is a name of user who loged in. (in 2000)
Here is a problem with SQL 2005. The schema's name is still IQA. But I need to do select * from IQA.table1.
I created IQA login and IQA user is an onwer my IQA schema but I still can not do a select without schema name. I need to resolve this because VB.Net code has all select statement without schema's name. Need help!!!

Information Schema is the part of the SQL-92 standard which exposes the metadata of the database. I have written a small article that exposes the same. Let me know your comments on the same. http://aspalliance.com/1380_Information_Schema_and_SQL_Server_2005

Hi Group,(I am just starting with SQL Server 2005.)On SQL Server 7 I used often the nice relation schema, where I used todraw out the whole database, especially the Foreign Keys constraints.I found these relational schemas very handy to study an old database Ibuild a few years earlier that needs some updating.I tried to find such an utility in SQL Server 2005, but cannot find it.I did found the FK-constraints, but it is just an popup where I candefine them.The overview such a visual schema gave was really great and I miss it.Question: Is it gone in SQL Sevrer 2005, or do I just not know where tolook? If the latter, please guide me. :)Thanks for your time.Regards,Erwin Moller

Hi everyone,
I'm currently investigating the security improvements of SQL Server 2005. I've got some problems with the schemas introduced in SQL 2005 and security settings.
For my test I've created two schemas: UserManagement and Sales. A user "test" is attached to the UserManagement schema. There's a table Sales.Users containing a list of users (varchar) and a stored procedure named UserManagement.AddUser that can be executed by the UserManagement schema (GRANT EXECUTE, so "test" can execute the SP). UserManagement.AddUser simply inserts a new row into Sales.Users.
Because the Sales schema doesn't contain any user, nobody (except the sysadmin, of course) can do a INSERT/SELECT/DELETE in the Sales.Users table. As expected, the following SQL statement fails:
EXECUTE AS LOGIN='machine est';
INSERT INTO Sales.Users VALUES('Test User');
INSERT was not allowed: object 'Users', database 'test', schema 'Sales'.
The second way of inserting rows into Sales.Users is to execute the stored proc UserManagement.AddUser:
CREATE PROCEDURE [UserManagement].[AddUser]
WITH EXECUTE AS CALLER
AS
INSERT INTO Sales.Users VALUES('Test User');
The user "test" can execute this sproc without problems:
EXECUTE AS LOGIN='machine est';
EXECUTE UserManagement.AddUser;
(1 row(s) affected)To my astonishment the INSERT statement inside the stored proc does execute - although UserManagement.AddUser and Sales.Users are two different schemas. Why is that, is there a chaining happening? To my understanding SQL Server should test INSERT rights on Sales.Users for the UserManagement schema and deny the INSERT statement because UserManagement isn't allowed to INSERT in the Sales schema.
Any ideas? Help regarding the issue is greatly appreciated.
Best regards,
Alex

We have a commercial VB.NET winforms client/server application that utilizes SQL Server 2005 express edition. The schema and data that the application utilizes is proprietary and could be very damaging if it got into a competitors hands.
Is there any way to protect the data and schema of a sql server 2005 express edition database?
Will this functionality ever be added?
Thanks

During web-site development, I am using VStudio 2005 with SQL-Express. I frequently publish changes to my web server that is running SQL- Server 2000 standard edition.
Is there a simple way to replicate changes in database tables design without copying the whole mdf-file and loosing the existing data in the target database?
thanks, Reinhard

I just upgraded from SQL 2000 to 2005 and have been reading up on the new 2005 schemas and how they can be used to simplify assigning permissions, etc. I started experimenting yesterday with a dummy database and ran into a few issues in which I have questions. Note, I am wanting to use Windows authentication as much as possible where end users will be accessing the database via a mapped Windows group. Based on what I've read thus far on the net this presents an issue in that users who access the database via a mapped windows group are not assigned a default schema.
My concern with migrating to using schemas for protecting objects is the potential for breaking existing applications based on the way objects are referenced in code. Most of the existing code simply references the object only ...such as 'mytable' vice 'dbo.mytable'. If I understand SQL 2005 schemas correctly if only the object is referenced in code (i.e. 'mytable') then SQL 2005 looks in the sys schema first then the dbo schema, etc. in attempt to find the object. Basically it defaults to the dbo schema. But issue I forsee is if I used a custom schema ('MySchema') coupled with users accessing the database via a mapped windows group. This is supposedly where a default schema cannot be assigned ...and since db objects won't reside in the 'dbo' schema the SQL won't be able to locate the referenced objects (I.e. 'mytable') and will in turn break applications?
If my assumptions above are correct then it would appear I have limited choices. Use the 'dbo' schema for everything ...or abandon schemas entirely?

I have SQL Server 2005 Express set up on a PC. I imported a backup of an MSDE database. All of the database objects are there. However, I need to assign permissions to my Stored Procedures. So, using Management Studio Express, I saw absolutely no way of adding a stored procedure to a schema or to a user. So I downloaded SQL Server 2005 Developer from my MSDN account. I installed the client tools to get the full version of Management Studio. Same thing. No way to add permissions to a SP. Some web articles say to right-click the SP and select Properties. However, there is no "Properties" in the right-click menu!!! There is only Rename, Delete, Modify, etc. How can something so easy with an old product be so difficult with a new one? Does anyone know how to accomplish adding permissions to SPs?I can right-click a table or a View and get the popup window with the list view and contents to set permissions to tables and views.

Hello,
In general, with the introduction of schemas in 2005, is it considered "bad practice" to tell people to create new tables in the "dbo" schema?
Our product documentation contains a "quick start" guide for users who just want to get the product up and runing. We suggest that the customer creates a database for our application. This database is configured with a user that is assigned to the 'db_owner' role (we want to keep things as simple as possible) that we use to connect to the database. This database will only be used by our application. In this situtation is it okay to use the "dbo" schema, or should we consider creating another schmea for all our tables?
Are the any "best practices" for using schemas in SQL 2005?
Thanks,
Brenden.

All,
I have been asked to grant a Windows group Full access to all tables under our Sandbox Schema. This will allow these users to do anything to the tables under this Schema.
I created the Windows Group (Sandbox Users), created the login in SQL, created the user in the database that is tied to the Windows group, then ran GRANT CONTROL ON SCHEMA::[Sandbox] TO [Sandbox Users].
I have verified that the users are in the Windows group, but they state that they still can not delete tables under the Sandbox Schema.
Anyone have any ideas?
Thanks,
Justin

I NEED HELP! Does anyone know how to remove a database schema from SQL Server 2005 using C#? I have a web application that deletes users. In SQL2k, I am able to simply delete the users. In SQL2005, I must delete or alter the schema BEFORE I can delete the users. Of course, the query below works, but how can I get this to work in code for a web application?
USE EAST_USERS
DROP SCHEMA "plijsmith"
Thanks

Hi,
In one of the application we recently migrated the database from MSSQL
2000 to MSSQL 2005.
We are using the user sa for our database and when we import data from one table to another ,we
are getting the error as "Ambigoius table name Address".
and in another machine we got this error message.
"The source DB Connection have access to multiple schemas. Restrict the
access to required schema for the user."
It is expecting some schema to be refered since all the database have
'sa' as user in common in MSSQL database.
can anyone show how the jdbc url syntax for including the schema in
MSSQL 2005 for the user sa ?
Thanks

Locally I develop in SQL server 2005 enterprise. Recently I recreated my db on the server of my hosting company (in sql server 2005 express).I basically recreated the tables and copied the data in it.I now receive the following error when I hit the DB:The 'System.Web.Security.SqlMembershipProvider' requires a
database schema compatible with schema version '1'. However, the
current database schema is not compatible with this version. You may
need to either install a compatible schema with aspnet_regsql.exe
(available in the framework installation directory), or upgrade the
provider to a newer version.I heard something about running aspnet_regsql.exe, but I dont have that access to the DB. Also I dont know if this command does anything more than creating the membership tables and filling it with some default data...Any other solutions/thought on what this can be?Thanks!

Just wondering if there are any tools available for SQL Server 2005 which allow the comparison and scripting of data and schema between two databases. This is so that I can migrate between Dev, QA, and Live easily.
A free tool would be best please..
Thanks in advance.

So on my local server I have a username CWI. I have my main DB: CW.
CWI is the owner of 5 schemas on CW, and everything works great.
---
I now go and create a new DataBase called CWTest. I want to now add the user CWI to the security section of CWTest (The same way I did it in 2000).
However, now I get the error message:
"The login already has an account under a different user name."
When I created my DataBase, IT had the default user, but now I want to add another user so I can create my schemas.
---
On our live servers, we will have 100-300 Databases all using the same useraccount as the "God Mode" user.
Any advice?

I restored a backup from SQL 2000 onto a new SQL 2005 server. The
database restored and the matching user who was the owner of that
database in SQL 2000 was created as a user in SQL 2005 as well as being
designated as the "schema" for that database. I was having
trouble logging in with the user that was created after the restore, so
I created a new user and assinged the new user as DBO of the new
database, set up the new users default database and schema, and
everything was working fine, my database driven application worked
perfectly under that user.
Then I installed SSIS, as it was recomended as a solution to another
problem. After installing SSIS I can not run queries without
specifying a schema name. For example this query will not work,
it returns table not found:
SELECT * FROM <table_name>
However if I specify the schema name like this, the results return:
SELECT * FROM <schema>.<table_name>
This screws up my database application as it does not include the schema name in its transactions.
I do not understand why installing SSIS would have changed this.

I'm building my app in the full blown MS SQL 2005 Standard Edition as our new app will have a enterprise version using SQL 2005 and a desktop version using either SQL Compact Edition 2005, VistaDB3, or maybe even (uggh) SQL Express 2005. I would prefer SQL Express 2005 but the install size of my app + DB would kill sales.
Back to my question. I'm building out the schema in the full SQL 2005, how do I take this schema and get the schema applied to a SQL Compact Edition DB?
Does SQL Compact Edition support DDL?
Thanks.

Hello,
I would like to use SSIS tool to move the data from one database schema to another database schema.
For example:
Source table has
1. UserName (varchar 20) (no null)
2. Email (varchar 50) (can be null)
Destination table has
1. UserID (uniqueidentifier - GUID)
2. UserName (varchar 50) (no null)
3. EmailAddress (nvarchar 50) (can be null)
4. DateTime
Questions:
1. What controls do I use in my Data Flow to make data move between databases with different data types and include new value in UserID as a new GUID and DateTime as a date (GETDATE)?
OLE DB Source, OLE DB Destination, Data Converson and .....
How do I insert Guid and Date at the same time?
2. I have many tables to do data moving. Any sugestions? How do I architect my project? If I create many data flows for each table - it will look complicated.
Please give me some advices here.
Thanks.
