title: Multi Thread in SQL?
body: <p>I have a SQL query Like</p>
  
  <pre><code>SELECT Column1, Column2, Column3, **ufn_HugeTimeProcessFunction**(Column1, Column2, @Param1) As Column4
  From Table1
  </code></pre>
  
  <p>This <strong>ufn_HugeTimeProcessFunction</strong> function run against large table (in terms of number of rows) and there are several calculation behind to return value.</p>
  
  <p>Am I able to force the SQL compiler to run that function in another thread (process)?</p>
  
  <p>Edited : Basically that function get the data from 3 different databases. That's why I am planing to run it "in parallel", moreover it is not possible to change the indexes on the other databases</p>
