Common commands to manage a Sql Instance

  • Article

This post is a repository of commands that I have been commonly using to manage a Sql Instance.

List the sys admins on a instance

select [name] from sys.syslogins where sysadmin=1

Add yourself/someone as a sysadmin on sql instance

EXEC master..sp_addsrvrolemember @loginame = N'redmond\pranavra', @rolename = N'sysadmin'

EXEC master..sp_addsrvrolemember @loginame = N'BUILTIN\Administrators', @rolename = N'sysadmin'

EXEC master..sp_addsrvrolemember @loginame = N'REDMOND\aapfte', @rolename = N'sysadmin'

 

Remove yourself/someone as a sysadmin on sql instance

EXEC sp_droprolemember 'sysadmin', 'redmond\pranavra'
