Hi All,
I'm extremely new at Powershell and not even close to an expert in ADO.NET, but I'm learning.
In the following script, the Insert statement works, but the return value of the newly inserted Primary Key is not.
Would someone be so kind to point out what I'm missing?
Thank you.

I've never used PowerShell but I'm interested in it... anyone got an idea on this problem? Thanks.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

Wow, I forgot all about this.

Turns out it was a very easy fix. I changed the Output parameter from AddWithValue to Add (not certain that that really did anything) but I also made the notated changed below:

$cmd.Parameters.Add("@NewCompID", [System.Data.SqlDbType]"Int").Direction = [System.Data.ParameterDirection]::Output

$cmd.Connection = $conn

# Execute Stored Procedure

$cmd.ExecuteNonQuery() | Out-Null

--#$NewCompID = $cmd.Parameters.("@NewCompID").Value ---- original

$NewCompID = $cmd.Parameters["@NewCompID"].Value

Thanks.
