title: Knime: If Contains Statement
body: <p>I’m trying to familiarize myself with column expressions node but having difficulties, can someone help me write out an “if contains” statement?</p>
  
  <p>I’d like to say:</p>
  
  <p>if column(A) contains category or value or data
  then column (B)
   else </p>
  
  <p>I know that I can do the same thing in rule engine and I was able to accomplish this statement in that node but I really want to understand column expressions node and how to write statements in it.</p>
  
  <p>Thank you for your time!</p>
