I am trying to use the %TEMP% variable to copy a .sql file , so I can run it. But somehow the %TEMP% is not expanding while running puppet and the statement is failing..

file{'SQL Script File': source => 'puppet:///modules/custom/updatelog.sql', path => '%TEMP%\updatelog.sql', }

Can some one tell me how to access these windows environment variables in puppet...?

I don't know how to extract environment variables in MS (as facts), but variable interpolation goes like this: https://docs.puppet.com/puppet/latest/lang_variables.html#interpolation

Does your %TEMP% appear in the output of `facter(8)`? Then you're lucky. Otherwise you have to write a program extracting your environment variable https://docs.puppet.com/facter/latest/custom_facts.html

Doesn't the MS world know something like the “filesystem hierarchy standard” (hier(7))? I mean, couldn't you just specify a static string like `/tmp` you'd usually do in the Linux world?

Unfortunately, puppet doesn't support windows environment variables in paths like that. You'll want to create a custom fact and then reference that fact in your manifest:

Facter.add(:temp) do
  setcode do
    ENV['TEMP']
  end
end

Then in your manifest:

path => "${temp}\\updatelog.sql"

In order to interpolate the temp fact value, you'll need to use double quotes, which means you have to escape the backslash.
