title: T-SQL RegExp to find sequential repeated characters
body: <p>I'm looking for a RegExp to find duplicated characters in a entire word in SQL Server and Regular Expressions (RegExp). For Example:</p>
  
  <pre><code>"AAUGUST"     match (AA)
  
  "ANDREA"      don't match (are 2 vowels "A", buit are separated)
  
  "ELEEPHANT"   match (EE)
  </code></pre>
  
  <p>I was trying with:</p>
  
  <pre><code>SELECT field1
  FROM exampleTable
  WHERE field1 like '%([A-Z]){2}%'
  </code></pre>
  
  <p>But it doesn't work. </p>
  
  <p>I apreciated for your help.</p>
  
  <p>Thanks!</p>
