How to add multiple logins to a role

Sometimes I'm in a position where I have to restore a production database to a development server, but there are a whole bunch of logins (belonging to developers) that don't exist in production which do on the development instance that need adding to a role so they can perform DML.

A way to get around this is to create a separate database and table on the development server which has a list of the logins and the roles they need to be added to and add a piece of TSQL similar to that below to the database restore job which adds the logins to the correct role: 

--------------------------------
-- Create the database
--------------------------------
CREATE DATABASE UserManagement CONTAINMENT = NONE ON PRIMARY (
       NAME = N'UserManagement'
       ,FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\DATA\UserManagement.mdf'
       ,SIZE = 5120 KB
       ,FILEGROWTH = 1024 KB
       ) LOG ON (
       NAME = N'UserManagement_log'
       ,FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\DATA\UserManagement_log.ldf'
       ,SIZE = 1024 KB
       ,FILEGROWTH = 10 %
       )
GO
--------------------------------`
-- Create database to hold the usernames we will give permissions to
--------------------------------
USE UserManagement;
GO

CREATE TABLE LoginsToAdd (
       UserName VARCHAR(50)
       ,RoleName VARCHAR(50)
       ,DBName VARCHAR(20)
       )
--------------------------
-- Add the user accounts and the roles they need to the databases.
-- NB The logins need to exist already
--------------------------
USE UserManagement;
GO

INSERT LoginsToAdd(UserName, RoleName, DBName)
SELECT 'LSMith','db_datareader','DB1'
UNION ALL
SELECT 'JJones','db_datareader','DB1'
UNION ALL
SELECT 'FPatel','db_datareader','DB1'
UNION ALL
SELECT 'SDeSouza','db_datareader','DB1'
UNION ALL
SELECT 'PHewson','db_datareader','DB1'
UNION ALL
SELECT 'SBaldry','db_datareader','DB1'
UNION ALL
SELECT 'KCarrington','db_datareader','DB1'
--------------------------------
-- Create logins using a cursor
--------------------------------
PRINT 'Updating users/logins for DB1 database'

DECLARE @UserCommand VARCHAR(512)
       ,@UserName VARCHAR(255)
       ,@RoleName VARCHAR(255)

DECLARE UserCursor CURSOR
FOR
SELECT UserName
       ,RoleName
FROM LoginsToAdd
WHERE DBName = 'DB1'

OPEN UserCursor

FETCH UserCursor
INTO @UserName
       ,@RoleName

WHILE 0 = @@fetch_status
BEGIN
       PRINT '--> Adding user ' + @UserName + ' to role ' + @RoleName

       SET @UserCommand = 'USE [DB1];
IF  EXISTS (SELECT * FROM sys.database_principals WHERE name = N''' + @UserName + ''')
DROP USER [' + @UserName + '];
                          
CREATE USER [' + @UserName + '] FOR LOGIN [' + @UserName + '];

ALTER USER [' + @UserName + '] WITH DEFAULT_SCHEMA=[dbo];

EXEC sp_addrolemember N''' + @RoleName + ''', N''' + @UserName + ''';'

       EXECUTE (@UserCommand)

       FETCH UserCursor
       INTO @UserName
              ,@RoleName
END

CLOSE UserCursor

DEALLOCATE UserCursor

How to configure the SSAS service to use a Domain Account

NB Updating SPNs in AD is not for the faint hearted plus I got inconsistent results from different servers. Do so at your own risk! If you need the SSAS account on a SQL Server to use a domain account rather than the local “virtual” account “NT Service\MSSQLServerOLAPService”. You may think you just give the account login permissions to the server, perhaps give it sysadmin SQL permissions too. However, if you try and connect to SSAS  remotely  you may get this error: Authentication failed. (Microsoft.AnalysisService.AdomdClient) The target principal name is incorrect (Microsoft.AnalysisService.AdomdClient) From Microsoft: “A Service Principle Name (SPN) uniquely identifies a service instance in an Active Directory domain when Kerberos is used to mutually authenticate client and service identities. An SPN is associated with the logon account under which the service instance runs. For client applications connecting to Analysis Services via Kerberos authentication, th

How to move the Microsoft Assessment and Planning Toolkit (MAP) database to a different drive

The Microsoft Assessment and Planning Toolkit (MAP) is a very useful tool for scanning your network to find instances of SQL Server plus all manner of detailed information about the installed product, OS and hardware it sits on. <Click image to enbiggen> There is an issue with it the database it uses to store the data it collects, however. Assuming you don't have an instance called MAPS on your server, the product will install using LocalDB (a cut down version of SQL Server Express) and puts the databases on your C: drive. If you then scan a large network you could easily expand the database to 10GB which may cause issues on a server when that drive is often one of the smallest. However, there is a simple solution: connect to LocalDB using Management Studio, detach the databases, move to a different drive, set permissions on the new location if required and reattach the database. How do you connect to LocalDB? Here you go: Connect to (localdb)\MAPTOOLKIT The

SAN performance testing using SQLIO

Introduction This document describes how to use Microsoft’s SQLIO to test disk/SAN performance. It is biased towards SQL Server – which uses primarily 64KB and 8KB data pages so I am running the tests using those cluster sizes, however, other sizes can be specified.  Download SQLIO from https://www.microsoft.com/en-gb/download/details.aspx?id=20163   SQLIO is a command line tool with no GUI so you need to open a command prompt at  C:\Program Files (x86)\SQLIO  after you have installed it. Configuration First of all edit param.txt so that you create the test file we will be using. The file needs to be bigger than the combined RAID and on-board disk caches. In this case we are using a 50GB file. The “ 2”  refers to the number of threads to use when testing, you don’t need to change this now. The “ 0x0”  value indicates that all CPUs should be used, which you probably don’t want to change either, “ #”  is a comment. The only part you may want to change is 51200 (50GB) a
