Do this work on LogicalPlan, rather than on DataFrame.

>
> When converting the calcite plan to spark LogicalPlan ，using the DataFrame
> interface means parsing while building the LogicalPlan.
> In this process，select, aggregation and other operators will execute the
> method below, we need care the invoking of "qe.assertAnalyzed()".
> {code:java}
> def ofRows(sparkSession: SparkSession, logicalPlan: LogicalPlan): DataFrame =
> sparkSession.withActive {
> val qe = sparkSession.sessionState.executePlan(logicalPlan)
> qe.assertAnalyzed()
> new Dataset[Row](qe, RowEncoder(qe.analyzed.schema))
> } {code}
