title: Combine Fields Value with Subquery Error: Subquery returned more than 1 value. This is not permitted when the subquery follows
body: <p>I created a view with the following SQL statement:</p>
  
  <pre><code>SELECT InventoryID, AccountCode, Description, Notes + N'N ' +
              (SELECT Deployment
              FROM    dbo.Deployment
              WHERE (dbo.Inventory.InventoryID = InventoryID)) AS Remarks
  FROM   dbo.Inventory
  </code></pre>
  
  <p>But this returns an error <code>Subquery returned more than 1 value. This is not permitted when the subquery follows.</code></p>
  
  <p>Here's the table structure and the sample output that I'd like:</p>

  <p>Is it possible to concatenate the value of <code>Notes</code> field with the subquery that has multiple values?</p>
  
  <p>Update:</p>
  
  <p>Here's the error. I also include the database structure in the image.</p>
