title: Table input insert data from step
body: <p>When I use table input and insert data from step to replace ? in the sql. </p>
  
  <p>For example,</p>
  
  <p><code>select * from a where b in (?)</code>.</p>
  
  <p>from mysql log, the sql is <code>select * from a where b in ('0,1,2,3')</code></p>
  
  <p>how can make it be executed without ' ?</p>
  
  <p>Thanks</p>
