title: INSERT INTO specific ROW - Insert into specific columns of a specific row?
body: <p>I am using SQL server 2008. I have a table in which the first three columns of each row remain FIXED while the other columns change. R = Row, C = Col.</p>
  
  <pre><code>   C1   C2   C3   C4   C5....
  R1:a    b    x    h    l 
  R2:p    d    b    r    v 
  R3:y    h    d    b    m
  .....
  </code></pre>
  
  <p>The data in columns C1, C2 and C3 never changes. But data in C4, C5 needs to be changed sometimes. </p>
  
  <p>What is the SQL query to update only cols C4, C5 etc. for a PARTICULAR row ?</p>
