Beginner Help With Insert

Hello,



First off, I'm completly new to SQL.
I'm trying to create an insert command that uses a select command as a value.


INSERT INTO Activation.dbo.Selected (PID) SELECT PID FROM ElecDB.dbo.PTT WHERE Vendor = 'guy'

What I get from this is 5 rows updated which is what I wanted.
Although, I would like to insert a UserID from C# code or for now just 1151 for example.
I'm assuming that it would look something like this:


INSERT INTO Activation.dbo.Selected (PID,UserID) SELECT PID FROM ElecDB.dbo.PTT WHERE Vendor = 'guy' , 1151


but I am not even close.
Please help me with this.

Thanks,
Guy
