hive通过元数据库查询分区和非分区的数据量及存储占用

非分区表：

SELECT
	a.TBL_ID,
	d.`NAME` dbName,
	a.TBL_NAME,
	b.PARAM_VALUE numRows,
	c.PARAM_VALUE totalSize
FROM
	TBLS AS a
	left JOIN TABLE_PARAMS AS b 
	on a.TBL_ID = b.TBL_ID
	left JOIN TABLE_PARAMS AS c
	on a.TBL_ID = c.TBL_ID
	left JOIN DBS as d
	on d.DB_ID = a.DB_ID
where 	 
	b.PARAM_KEY = "numRows"
	and 
	c.PARAM_KEY = "totalSize"

分区表：

SELECT 
    main.dbName,
    main.TBL_NAME,
    SUM(b.numRows) AS totalNumRows,
    SUM(b.totalSize) AS totalSize
FROM (
    SELECT 
        main.TBL_ID, 
        d.`NAME` AS dbName,
        main
