How to grant users read-only access to all databases

I want a group of users to have read-only access to all tables and views on all databases on SQL Server (I'm using SS2008). I'd like t开发者_C百科hose users to have read-only access to all future tables and view.

How would you set that up?

add the user to the db_datareader role

example

exec sp_addrolemember 'db_datareader',YourLogin

Info about db_datareader: http://msdn.microsoft.com/en-us/library/ms188629(SQL.90).aspx

DECLARE @dbname VARCHAR(50)
DECLARE @statement NVARCHAR(max)
DECLARE db_cursor CURSOR

LOCAL FAST_FORWARD
FOR SELECT name FROM MASTER.dbo.sysdatabases OPEN db_cursor
    FETCH NEXT FROM db_cursor INTO @dbname 
WHILE @@FETCH_STATUS = 0
BEGIN
    /* This sentence will be executed to gran the privileges. */
    SELECT @statement = 'use ['+@dbname+']; '+'EXEC sp_addrolemember N''db_datareader'', N''userPeter''';
    EXEC sp_executesql @statement
    FETCH NEXT FROM db_cursor INTO @dbname
END

In the location that appear userPeter you must write your username.

You should just be able to add the users to the db_datareader database role in each of the databases. You could write a script to loop through the databases and do it for you.
