title: sql replace function that matches whole words
body: <p>I wish to replace some text within a field, so i have the following statement:</p>
  
  <pre><code>UPDATE INVENTORY
  SET INV_DESCRIPTION = REPLACE(INV_DESCRIPTION, '5 ml', '5ml (1/6oz)')
  </code></pre>
  
  <p>The problem lies in the fact that this statement will replace strings such as '5 ml' '15 ml' '150 ml' etc, with the replacement string.  I wish for this function to match the whole word and just look for '5 ml'</p>
