PowerShell Export SQL Agent Job

This brief post is in response to a comment on my post PowerShell export query to CSV. Octopusgrabbus, awesome handle, asked how one could launch this. If you were looking to make this into a SQL Agent job, then I'd simply create a new job, add a step of type PowerShell and then you can literally paste in the script I referenced in the previous article.

If you prefer a script approach, this should create a job named PowerShellExportTest and with a single step named PS test. When the job runs, the query in line 30 will run and generate a CSV to the path defined on line 35.

   1:  USE [msdb]
   2:  GO
   3:  DECLARE @ReturnCode INT
   4:  DECLARE @jobId BINARY(16)
   5:  EXEC @ReturnCode =  msdb.dbo.sp_add_job @job_name=N'PowerShellExportTest',
