title: How do I aggregate on a text field?
body: <p>I want to roll up on ProductID and append all the ingredients together in the rolled-up row for that ProductID. ProductID is the "GROUP BY", what operator can be used on the Ingredient field.</p>
  
  <p>This is not a data warehouse. I know STRING_AGG is available in SQL Server 2017 and I don't have that either, I have SQL Server 2012.</p>
