title: SQL SELECT query not working in mysql
body: <p>I have an sql query:</p>
  
  <p><code>SELECT * FROM presentations_db.presenters_tbl WHERE e-mail LIKE '%@%';</code></p>
  
  <p>It does not seem to work and I don't know why. If I remove the WHERE part it works, but includes all records. I only want records that have an e-mail address. I am using mysql workbench. The e-mail field is a VARCHAR(45). It seems so simple but not... There is no feedback or error messages. The result list doesn't even open.</p>
