Stairway to SQL PowerShell Level 10: Getting data in and out of SQL Server using SQL Server PowerShell

In this level we will look at ways of getting data into and out of SQL Server. We will specifically look at the Database object and a cmdlet Invoke-Sqlcmd or Invoke-SqlCmd2. To get data in, we are going to leverage a PowerShell script that uses SMO to put data into a predefined table in SQL Server.

Question of the Day

Finding Trailing Spaces

I have some data in a SQL Server 2025 database. It looks like this for the dbo.Customer table:

CustomerID CustomerName PreferredName
1          Steve        Steve               
2          Andy         Andy               
3          Brian        Brian               
4          Allan        Allan               
5          Devin        Devin               
6          Steve        Steve               
7          Sally        Sally
I want to detect which names have a single trailing space. The CustomerName is a varchar() and the PreferredName is a CHAR(). Does this query detect the problem rows?
SELECT 
       CustomerID,
       CustomerName,
       PreferredName
FROM Customer
WHERE CustomerName <> RTRIM(CustomerName)
OR PreferredName <> RTRIM(PreferredName);
