PowerShell Invoke-Sqlcmd switches into sqlps session

Question

I am writing a script in PowerShell ISE and I am using Invoke-Sqlcmd. After the command is executed the Powershell session switches into sqlps session (PS SQLSERVER:>) and I can

Answer 1

The sqlps module's behavior is to leave you in the psdrive that it creates. I'm fairly certain that people have asked Microsoft to fix this, as it's very annoying and disruptive.

The automatic importing of modules introduced by PowerShell 3.0 makes this even more annoying, because you may not even realize that you're importing the module until after the fact.

When I use sqlps, I explicitly import it so that I can control my working directory as follows:

push-location
import-module sqlps -disablenamechecking
pop-location

This returns you to your previous directory after the module is loaded.

Very late edit: With the advent of SQL Server Management Studio 2016 we have a new PowerShell module, sqlserver, which supersedes sqlps and resolves this problem.
