> In `PreValidateReWriter#appendPartitionAndNullsProjects`, we should use
> {code:java}
> val names = sqlInsert.getTargetTableID.asInstanceOf[SqlIdentifier].names
> {code}
> to get the table name, instead of
> {code:java}
> val names = sqlInsert.getTargetTable.asInstanceOf[SqlIdentifier].names
> {code}
> when we execute the following sql:
> {code:java}
> insert into/overwrite table_name /*+ options(xxx) */ partition(xxx) select  {code}
> invoke `sqlInsert.getTargetTable` will get a SqlTableRef, which can not be cast to SqlIdentifier.
