title: No column name was specified for column 1 of 'sp'
body: <p>I have following query:</p>
  
  <pre><code>SELECT s."Description",
  sp.*
  FROM "Supplier" as s
  OUTER APPLY (
      SELECT p."Id", p."Description", p."Price"
      FROM "Products" as p
      WHERE p."SupplierId" = s."Id"
      FOR JSON auto 
  ) as sp
  </code></pre>
  
  <p>I'm trying to build json array according to <code>OUTER APPLY</code> result but I stuck here because there is an error <code>No column name was specified for column 1 of 'sp'.</code> I found similar question here on stackoverflow, but there is no example with outer apply. </p>
  
  <p>Can you explain me what is wrong with this query?</p>
