title: How to merge MySQL data
body: <p>There are two schemas in MySQL. For example <code>db1</code> and <code>db2</code>.</p>
  
  <p>They have same structure of tables and different data to each other.</p>
  
  <p>Now I want to merge data on <code>db1</code> with data on <code>db2</code>.</p>
  
  <p>I tried below:</p>
  
  <ol>
  <li><p><code>mysqldump</code> from <code>db1</code> with no drop table option.</p></li>
  <li><p>Import dumpfile into <code>db2</code> to use RESOURCE command.</p></li>
  </ol>
  
  <p>But it didn’t work, nothing was added?</p>
