Powershell script for unattended install of SQL Server standard patches

23 July,2019 by Tom Collins

Question: Do you have a powershell script allowing me to dynamically create a drive - pointing to a network share , and then start an unattended install of SQL Server patching? I'll afdapt the script to drop onto a server and execute according to schedule .

Answer: Here is an example of  powershell script that applies SQL Server 2016 SP2 CU7 , although you can apply the same framework for other patching .

Some key points to note:

1) Replace "my_path" with the network path . The drive is added by use of the PS-Drive cmdlet. If you want to read more on creating a drive through Powershell read Powershell assign a drive and mount point 

This step creates a PS-Drive , which can then be accessed by later stages of the script

2)Replace "myPatch" , with the actual SQL Server patch file - which should be located on the drive you referenced above.  This uses the Start-Process cmdlet .



@echo off
echo	Unattended install of SQL Server 2016  Standard patches
%SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe New-PSDrive -Name "S" -Root '"\\my_path\"' -Persist -PSProvider "FileSystem"


echo %SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe Start-Process -FilePath "S:\myPatch.exe" -ArgumentList "/quiet" -Wait
%SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe Start-Process -FilePath "S:\myPatch.exe" -ArgumentList "/allinstances " -Wait


echo setup_SQL_Server_2016_patches
echo setup_SQL_Server_2016_patches [InstanceName]
