title: Exception/Error Handling in q kdb -- Alternative of Try-Catch-Finally(Java)/Try-Except-Finally(Python)
body: <p>As we have try-catch in java, I can find trap-at in q kdb.<br>
  But my requirement is of try-catch-finally i.e in try block I'm opening odbc connection and in finally I want to close odbc connection.</p>
  
  <pre><code>Sudo code:
  
  try{
    con=openODBCConnection(dbName);
    //n statements;
  }catch(Exception e){
     catchingNotSoImpException(e)
  }finally{
   closeODBCCon(con);
  }
  </code></pre>
