I have a script that runs Invoke-SQLCmd against a SQLServer called Server1. Data that is collected from that is passed along to another script that is fired off against Server2 and the results are inserted back into a table on Server 1. On every Invoke-SQLCmd I have used the -user -password with an account that has sa permissions on both systems.

When i run the script from the command shell or from the Poershell ISE my data is inserted into the table and every thing works fine; When i run it from within SQL nothing happens. I get no outputs ("null" is returned) when i use xp_cmdshell as below.

xp_cmdshell 'powershell.exe -file c:\script.ps1 -ExecutionPolicy Unrestricted'

I have put it into a SQLjob and used a proxy account that links to my domain account that has admin rights on both boxes yet still no results recorded in the job history and no data in my table on Server1.

What am i doing wrong? surely this should work if it works from the ISE?

I haven't had any problem doing this and even created a couple of blog posts:

The one thing that I'm doing differently is using the -command parameter with a file name instead of -file, but that shouldn't make a difference. I'm also enclosing the file name in double quotes but this shouldn't make a difference either if the script file has not spaces in the file path.

Outside of that I would need to see what your script is doing. For instance is it connecting to other machines? Can you run a simple command in powershell like 'powershell -command get-command'?

It would seem that i was not loading the snapins correctly. Although my SQLsnapins were loaded for the first session it wasnt passing it to the second PS script that was running invoke-SQLcmd. My second script did add the cmdlet snapin but that may not have been enough.

It should have worked but for whatever reason, adding the script block from here fixed it. :/

What am i doing wrong?

I think there is an error in the example provided. I would have expected:

xp_cmdshell 'powershell.exe -ExecutionPolicy Unrestricted -file c:\script.ps1'

Because: "File must be the last parameter in the command, because all characters typed after the File parameter name are interpreted as the script file path followed by the script parameters and their values."
