Sql-server – Passing current server name from SQL Server Agent job to PowerShell

If you look in SQL Server BOL, SQL Server Agent provides a set of "tokens" that it will substitute into both the job step command text and the output file (the later will prevent the GUI "view" button from working). These tokens seem to work for any type of step except T-SQL.

https://docs.microsoft.com/en-us/sql/ssms/agent/use-tokens-in-job-steps#sql-server-agent-tokens

So, if you have a SQL 2008 PowerShell step, you can start it with:

$sqlInstance = "$(ESCAPE_DQUOTE(SRVR))"

You may need to use MACH (machine name) and INST (just instance name) instead, because with the default instance SRVR == MACH, but with named instances SRVR == MACH\INST.

You will have to use tokens in your job steps to get your own job id. Details here: Using Tokens in Job Steps.

At the end of the article there's one example with jobid:

SELECT * FROM msdb.dbo.sysjobs
WHERE @JobID = CONVERT(uniqueidentifier, $(ESCAPE_NONE(JOBID))) ;
