title: How to capture the output after querying the tdbrow in talend and display it?
body: <p>I am extracting the filename from tfilelist and i am checking against the database if that filename exists in the table and display the corresponding output?
  I cannot see the output when i tried with both tlogrow and tjavarow component after tbdrow/tbinput.</p>
  <p>Not sure what i am missing,and also i would want to store the filename and do a check if it exists print a message such as &quot;file exists&quot; and how do i do the IF condition after displaying the output?</p>

  <p>I am just iterating from tbdinput to tbdrow to see which one works best,i feel its redundant since both the components can be used to query the db and return the results?Which one is better to use even though for faster results?</p>
