title: SQL - How to replace Datetime value with other Datetime?
body: <p>Before I go messing my database up, I have a quick question:</p>
  
  <p>What is the SQL command to replace a datetime value with another datetime value? I'm going to replace all datetimes in a single column of my database table with '0000-00-00 00:00:00'.</p>
  
  <p>I'm guessing that the SQL command is like this command to replace all string values in a single column/table?:</p>
  
  <pre><code>UPDATE table_name SET field_id = '0000-00-00 00:00:00'
  </code></pre>
  
  <p>This is my first time replacing all DateTime values like this - YES, I have already made a DB backup, just in case!</p>
