Using Environment variables in T-SQL

Question

How can I read the value of a system environment variable in a T-SQL script?

This is to run on SQL Server 2005.

Answer 1

To "read the value of a system environment variable in a T-SQL script" you can set SQL Management Studio to use "sqlcmd Mode".

Then you can use like this:

Print '$(TEMP)'

:r $(Temp)\Member.sql
go

I'm not sure how this is done outside of "SQL Management Studio" but it should be hard to find out.
