title: Oracle: Combine multiple results in a subquery into a single comma-separated value
body: <p>I'm trying to convert a single-columned subquery into a command-separated <code>VARCHAR</code>-typed list of values.</p>
  
  <p>This is identical to <a href="https://stackoverflow.com/questions/111341/combine-multiple-results-in-a-subquery-into-a-single-comma-separated-value">this question</a>, but for Oracle rather than SQL Server or MySQL.</p>
