title: Merging two tables the rails way
body: <p>I'm using Rails 2.3.5 with ActiveRecord, ruby 1.8.6, mysql (2.8.1)</p>
  
  <p>I have two tables A and B with the exact same column structures.  A is on a separate server from B.</p>
  
  <p>I want to take the entire contents of B and add them to A so  </p>
  
  <p>A = A + B </p>
  
  <p>Any elegant methods?  I thought about taking one record at a time from B and just adding it into A, but that doesn't seem that great..</p>
