title: mySQL Query Remove Null Records in Column
body: <p>I have a large mySQL database and I want to remove every record that is empty, not null in a certain column. What is the best way to do write a SQL query for this?</p>
  
  <p>Currently I have tried:</p>
  
  <pre><code> DELETE FROM Businesses WHERE WEBADDRESS IS NULL
  </code></pre>
  
  <p>But it did not delete anything. There are 44,000 records and almost 80% of them are null in that column.</p>
