Microsoft routinely releases service packs for SQL Server that must be installed.
Every service pack installer for SQL Server supports silent installations.
This installation punch in enables you to use the command line to kick off an installation.
A quick way to do so is to use PowerShell.
I prefer to use a function calledTest-PendingReboot.
To extract the installer, use the arguments/extract:“C:TempSQLSP” /quiet.
You have one last task to perform, though, cleaning up.
To deploy a service pack to multiple servers, use PowerShell constructs like a foreach loop.
