title: How to use regular expression in TSQL?
body: <p>I'd need to have a regular expression so that I can find all invalid email addresses in our database table.</p>
  
  <pre><code>SELECT *
  FROM dbo.[Users] AS u 
  WHERE u.EmailAddress not like 'regular expression of valid email addresses'
  </code></pre>
  
  <p>Does SQL Server support regular expressions? If so, how could I write one for email address?</p>
