             Summary: when use prepareStatement parse and run RelNode or Queryable, Maybe Confusing log information be thrown
                 Key: CALCITE-4585
                 URL: https://issues.apache.org/jira/browse/CALCITE-4585
             Project: Calcite
          Issue Type: New Feature
          Components: core
    Affects Versions: 1.26.0
            Reporter: duan xiong


This code capture the exception,But Only the output of SQL exception is processed.So need to add the procedure to handle extra exception. 
{code:java}
// 
try {
  final Meta.Signature signature =
      parseQuery(query, createPrepareContext(), -1);
  final CalcitePreparedStatement calcitePreparedStatement =
      (CalcitePreparedStatement) factory.newPreparedStatement(this, null,
          signature, resultSetType, resultSetConcurrency, resultSetHoldability);
  server.getStatement(calcitePreparedStatement.handle).setSignature(signature);
  return calcitePreparedStatement;
} catch (Exception e) {
  throw Helper.INSTANCE.createException(
      "Error while preparing statement [" + query.sql + "]", e);
}

{code}
When we run RelNode or  queryable show wrong,this exception can be:

"Error while preparing statement [null]"

 can't log the real exception
