			LAST_DAY(
				DATE_FORMAT(NOW(), '%Y-%m-%d')
			),
			'%Y%m%d'
  	) AS 业务日期,
		MAX(CASE INDEX_CODE WHEN 'IND20101001' THEN PRSN_TOTAL END) AS 用户注册量,
		MAX(CASE INDEX_CODE WHEN 'IND20204001' THEN PRSN_TOTAL END) AS 完成三项认证人数,
		MAX(CASE INDEX_CODE WHEN 'IND20501001' THEN PRSN_TOTAL END) AS 投资人数,
		MAX(CASE INDEX_CODE WHEN 'IND20501001' THEN COUNT_TIME END) AS 投资笔数,
		MAX(CASE INDEX_CODE WHEN 'IND20504001' THEN PRSN_TOTAL END) AS 新客投资人数,
		MAX(CASE INDEX_CODE WHEN 'IND21101001' THEN COUNT_TIME END) AS 满标个数,
		MAX(CASE INDEX_CODE WHEN 'IND20501001' THEN AMOUNT END) AS 投资金额（元）,
