title: Can't read fields from previous step, kettle
body: <p>I have a small problem in kettle. These are the steps I'm using.

  <p>The error is at the second step saying that it's unable to get fields from the previous step because of an error, but the sql in "Table input" step works fine.</p>
  
  <p>Any ideas?</p>
