col_name3, ...] )]
> elect_expr [, select_expr ...]
> [FROM table_references
> PARTITION partition_list]
> [TABLET tabletid_list]
> [TABLESAMPLE sample_value [ROWS | PERCENT]
> [REPEATABLE pos_seek]]
> [WHERE where_condition]
> [GROUP BY [GROUPING SETS | ROLLUP | CUBE] {col_name | expr |
position}]
> [HAVING where_condition]
> [ORDER BY {col_name | expr | position}
> [ASC | DESC], ...]
> [LIMIT {[offset,] row_count | row_count OFFSET offset}]
> [INTO OUTFILE 'file_name']
> if analyzedPlan contains the stmt as following:
> PARTITION partition_list]
> [TABLET tabletid_list] or
> [TABLESAMPLE sample_value [ROWS | PERCENT]
