title: Regular expression filter
body: <p>I have this regular expression in my sql query</p>
  
  <pre><code>DECLARE @RETURN_VALUE VARCHAR(MAX)  
  IF @value LIKE '%[0-9]%[^A-Z]%[0-9]%'
  BEGIN
      SET @RETURN_VALUE = NULL
  END
  </code></pre>
  
  <p>I am not sure, but whenever I have this in my row 12 TEST then it gives me the value of 12, but if I have three digit number then it filters out the three digit numbers.How can I modify the regular expression to return me the three digits numbers too.</p>
  
  <p>any help will be appreciated.</p>
