I assume the best way to set my SSMS (SQL Server 2005) output file path during runtime of T-SQL, is to use SQLCMD mode.
How do I use environment variables (e.g. %systemroot%) in the code? The following bombs:
:set mypath %systemroot%
select * from myTab
In other words, when using SQLCMD not from the command line, but inside my T-SQL code. I just need to sort out the syntax.
(And also perhaps, though forum protocol is probably to ask it as separate questions:
Is there an environment variable for the folder of this .sql / the working folder?
How do I prevent the line counts to go to my output file also? )
