Powershell - Start or Stop SQL service on remote server

 You can use below script to start and stop remote SQL services.

* Just for one computer

(Get-Service -ComputerName YOURCOMPUTERNAME -Name 'SQLAgent').Stop()
(Get-Service -ComputerName YOURCOMPUTERNAME -Name 'SQLAgent').Start() 

* For multiple computer

$ServerList = Get-Content "DRIVE\ServerNames.txt"

ForEach ($ServerName in $ServerList)
{
    Write-Host $ServerName
    (Get-Service -ComputerName YOURCOMPUTERNAME -Name 'SQLAgent').Stop()
    (Get-Service -ComputerName YOURCOMPUTERNAME -Name 'SQLAgent').Start()

}

Powershell - Run SQL Scripts on Multiple Servers

 You must need SqlServer module is the current PowerShell module to use below script.

The SqlServer module comes with:

• PowerShell Providers, which enables a simple navigation mechanism similar to file system paths. You can build paths similar to file system paths, where the drive is associated with a SQL Server management object model, and the nodes are based on the object model classes. You can then use familiar commands such as cd (alias for Set-Location) and dir (alias for Get-ChildItem) to navigate the paths similar to the way you navigate folders in a command prompt window. You can use other commands, such as ren (alias for Rename-Item) or del (alias for Remove-Item), to perform actions on the nodes in the path.

• A set of cmdlets that support actions such as running a sqlcmd script containing Transact-SQL or XQuery statements.

• The AS provider and cmdlets, which before they were installed separately.

   

  YOU NEED TO  PUT ALL SQL SERVER INSTANCE NAMES IN INSTANCENAME.txt file in order to run below script. I use  this scripts a lot to update or pull many information from different servers.
  

   

  $ServerList = Get-Content "DRIVE\InstanceName.txt"
  $SourceDatabase = "master"
  $Script1 = "select @@servername"
  
  ForEach ($ServerName in $ServerList)
  {
      Write-Host $ServerName
      invoke-sqlcmd -ServerInstance $ServerName -Database $SourceDatabase -Query $Script1
  
  }
  

   

   Comment your thought regarding this script. Let me know if you need to generate any scripts for your project I will be happy to help you out. 

  
  

Generate Object Level Permission

Run below script to generate users and permission in any databases.
Mostly it helps to generate users and its permission before refreshing from prod database or migrating to another server.




SELECT 'CREATE USER [' + name + '] for login [' + name + ']' from sys.database_principals
-- where
 --Type = 'U'
 --and
 -- name not like '%'
 --------------------------------------
 SELECT 'EXECUTE sp_AddRoleMember ''' + roles.name + ''', ''' + users.name + '''' from sys.database_principals users inner join sys.database_role_members link on link.member_principal_id = users.principal_id inner join sys.database_principals roles on roles.principal_id = link.role_principal_id
 -----------------------------------
 if object_id('dbo.tempPermissions') is not null Drop table dbo.tempPermissions Create table tempPermissions(ID int identity , Queries Varchar(255)) Insert into tempPermissions(Queries) select 'GRANT ' + dp.permission_name collate latin1_general_cs_as + ' ON ' + s.name + '.' + o.name + ' TO ' + '[' +dpr.name + ']' FROM sys.database_permissions AS dp INNER JOIN sys.objects AS o ON dp.major_id=o.object_id INNER JOIN sys.schemas AS s ON o.schema_id = s.schema_id INNER JOIN sys.database_principals AS dpr ON dp.grantee_principal_id=dpr.principal_id WHERE dpr.name NOT IN ('public','guest') declare @count int, @max int, @query Varchar(255) set @count =1 set @max = (Select max(ID) from tempPermissions) set @query = (Select Queries from tempPermissions where ID = @count) while(@count < @max) begin exec(@query) set @count += 1 set @query = (Select Queries from tempPermissions where ID = @count) end select * from tempPermissions drop table tempPermissions

SQL - Find out database restored history

Find the history of SQL database backups.

You need to add database name where I put DBNAME in this script. It will give you full, differential and log backup history. I know how important it is in DBA's daily routine.
SELECT
CONVERT(CHAR(100), SERVERPROPERTY('Servername')) AS Server,
msdb.dbo.backupset.database_name,
msdb.dbo.backupset.backup_start_date,
msdb.dbo.backupset.backup_finish_date,
CASE msdb..backupset.type
WHEN 'D' THEN 'Database'
WHEN 'L' THEN 'Log'
END AS backup_type,
msdb.dbo.backupset.backup_size,
msdb.dbo.backupmediafamily.physical_device_name,
msdb.dbo.backupset.name AS backupset_name



FROM msdb.dbo.backupmediafamily
INNER JOIN msdb.dbo.backupset ON msdb.dbo.backupmediafamily.media_set_id = msdb.dbo.backupset.media_set_id
WHERE


--(CONVERT(datetime, msdb.dbo.backupset.backup_start_date, 102) >= GETDATE() - 7)

--and
msdb.dbo.backupset.database_name = 'DBNAME'
and msdb..backupset.type = 'D'
ORDER BY
msdb.dbo.backupset.database_name,
msdb.dbo.backupset.backup_finish_date desc

Find out from SQL Management studio - Who is part of network group id?

I have script which tells you who is part of groupid. It helps to find some login issue.


declare @DomainGroupName varchar(50)

select @DomainGroupName = 'domain\GroupIDName'

exec xp_logininfo @DomainGroupName,'members'

Script User, Database and Object Permission in SQL Server 2005 and onward

Generate Create User Script on a Database

 

SELECT 'CREATE USER [' + name + '] for login [' + name + ']'

from sys.database_principals

where

 Type = 'U'

  and

name <>  'dbo'

Generate Database role permission on a Database

 

 

 

SELECT 'EXECUTE sp_AddRoleMember ''' + roles.name + ''', ''' + users.name + ''''

from sys.database_principals users

inner join sys.database_role_members link

on link.member_principal_id = users.principal_id

inner join sys.database_principals roles

on roles.principal_id = link.role_principal_id

 

 

Generate Object Level peremission on a Database

 

 

if object_id('dbo.tempPermissions') is not null

Drop table dbo.tempPermissions

Create table tempPermissions(ID int identity , Queries Varchar(255))

Insert into tempPermissions(Queries)

select 'GRANT ' + dp.permission_name collate latin1_general_cs_as

+ ' ON ' + s.name + '.' + o.name + ' TO ' + dpr.name

FROM sys.database_permissions AS dp

INNER JOIN sys.objects AS o ON dp.major_id=o.object_id

INNER JOIN sys.schemas AS s ON o.schema_id = s.schema_id

INNER JOIN sys.database_principals AS dpr ON dp.grantee_principal_id=dpr.principal_id

WHERE dpr.name NOT IN ('public','guest')

declare @count int, @max int, @query Varchar(255)

set @count =1

set @max = (Select max(ID) from tempPermissions)

set @query = (Select Queries from tempPermissions where ID = @count)

while(@count < @max)



begin
 exec(@query)

set @count += 1

set @query = (Select Queries from tempPermissions where ID = @count)



end
 select * from tempPermissions

drop table tempPermissions 

I have struggle a lot to find out those scripts but I always try to make like simple for other DBA's.
let me know if you have any questions.
