title: TSQL Technique for attribute evaluation
body: <p>I have a table with 20 columns.  The first is my primary key.  The remaining columns are attributes about the primary key.   I need to evaluate each column on a row by row basis.   If a attribute column has a value other than null, then do some further processing.</p>
  
  <p>The way I am familiar with doing this in TSQL would be a while to bump through the rows, capture the values from the columns, evaluate the values for further processing.</p>
  
  <p>Does anyone have any better ideas?</p>
