EXEC - INSERT

You can return the results of a dynamic sql statement into a temp table or table variable:

DECLARE @tab TABLE ( id int, val varchar(100) )
DECLARE @sql varchar(8000)

SET @sql = "SELECT id, name FROM dbo.mytable"

INSERT INTO @tab ( id, val )
EXEC( @sql )

Installing Reporting Services

You have to open your browser (on server console or during a remote session) using "Run as Administrator".

Then go to http://localhost/Reports (NOTE: do not put http:///Reports - it doesn't work).

Go to Folder Settings and assign role browser and content manager to your administrator account. It should start working now.

If you are running it on Windows server 2008 don't forget to create inbound rule in windows firewall to port 80.

SQL Server Limiting Data Access for a Server Admin

If a user is granted the following server roles they still cannot access the data of databases they are not a user or dbo.


serveradmin - can change server configuration parameters and shut down the server.

setupadmin - can add or remove linked servers, manage replication, create, alter or delete extended stored procedures, and execute some system stored procedures, such as sp_serveroption.

securityadmin - can create and manage server logins and auditing, and read the error logs.

processadmin - can manage the processes running in SQL Server.

dbcreator - can create, alter, and resize databases.

diskadmin - can manage disk files.



----------- example script -----------

use master
go



EXEC sys.sp_addsrvrolemember @loginame = [testuser], @rolename = N'securityadmin'
GO

EXEC sys.sp_addsrvrolemember @loginame = [testuser], @rolename = N'serveradmin'
GO

EXEC sys.sp_addsrvrolemember @loginame = [testuser], @rolename = N'setupadmin'
GO

EXEC sys.sp_addsrvrolemember @loginame = [testuser], @rolename = N'processadmin'
GO

EXEC sys.sp_addsrvrolemember @loginame = [testuser], @rolename = N'diskadmin'
GO

EXEC sys.sp_addsrvrolemember @loginame = [testuser], @rolename = N'dbcreator'
GO

EXEC sys.sp_addsrvrolemember @loginame = [testuser], @rolename = N'bulkadmin'

----------- example script -----------
To allow backing up of a database they do have access to, then can use the following:


use [user_database]
go

grant backup database to [testuser]
go
