title: SQL to get only string with leading numbers
body: <p>I think this is fairly simple. I'd like to only return the string values that contact leading numbers in my query results.</p>
  
  <p>For example:</p>
  
  <pre><code>003 - Preliminary Examination Plan  
  005 - Coordination  
  1000a - Balance sheet
  Advertising  
  Amortization  
  Partnerships
  </code></pre>
  
  <p>Would like to get:</p>
  
  <pre><code>003 - Preliminary Examination Plan  
  005 - Coordination  
  1000a - Balance sheet
  </code></pre>
  
  <p>This code gave me zero results. How do I check if the leading numbers contain digits and return the rest of string?</p>
  
  <pre><code>select distinct AIssue
  from SQLIssue
  where regexp_like( AIssue, '^[[:digit:]]*$' )
  order by AIssue
  </code></pre>
