title: Insert DATEDIFF Result into a column in table?
body: <p>I have a query in SQL Server where it computes the difference between two dates, it's okay I get the result properly but I want that result to be stored in one of my columns in the Database. I can only work out how to display datediff but not how to store the result in a column.</p>
  
  <pre><code>select DATEDIFF (DAY,date_1,date_2) As date_test from tbl_datetest;
  </code></pre>
