首页统计查询，一周7天的数据统计，没有的补零，成功率计
1、先用一个查询把指定日期范围的日期列表搞出来（一周七天（LImit 7））：
tips：t_admin_user 不固定，任意一张表中的数据大于等于日期范围即可
注意：'@' 表示：在sql中创建变量，':=' 表示：在sql中赋值操作
SELECT
@OLD_CREATE := DATE_SUB( @OLD_CREATE, INTERVAL 1 DAY ) AS date_str,
0 AS count_str
FROM
( SELECT @OLD_CREATE := DATE_ADD( CURDATE( ), INTERVAL 1 DAY ) FROM t_admin_user LIMIT 7 ) t12、查询符合条件的有效数据，并且给日期设置别名即可：
tips：判断业务场景数据：（CASE WHEN a = 0 THEN a ELSE 1 END）
SELECT
COUNT( t.PAY_ID ) AS countNumber,
SUM( CASE WHEN t.RESULT_STATUS = ( 1 ) THEN 1 ELSE 0 END ) AS successNumber,
SUM( t.PAY_AMOUNT ) AS orderAmount,
SUM( CASE WHEN t.RESULT_STATUS = ( 1 ) THEN t.PAY_AMOUNT ELSE 0 END ) AS successAmount,
SUM( CASE WHEN t.RESULT_STATUS = ( 1 ) THEN t.TIP ELSE 0 END ) AS tip,
CONVERT ( t.create_time, DATE ) AS date_str,
SUM( CASE WHEN t.RESULT_STATUS = ( 1 ) THEN t.TOTAL_AMOUNT ELSE 0 END ) AS totalAmount
FROM
t_pay t
WHERE
t.FLAG = 0
GROUP BY
( CONVERT ( t.create_time, DATE ) )3、把两个表的查询结果用左连接合起来，没有日期的数据用0来补充：
SELECT
t2.date_str, -- 日期
COALESCE(t3.countNumber, 0) AS countNumber, -- 订单
COALESCE(t3.successNumber, 0) AS successNumber, -- 成功
COALESCE(t3.orderAmount, 0) AS orderAmount, -- 订单
COALESCE(t3.successAmount, 0) AS successAmount, -- 成功
COALESCE(t3.tip, 0) AS tip, -- 订单
COALESCE(t3.totalAmount, 0) AS totalAmount, -- 付
COALESCE(t4.topUpAmount, 0) as topUpAmount, -- 充值
COALESCE(t4.topUpTip, 0) AS topUpTip -- 充值
FROM
(SELECT
@OLD_CREATE := DATE_SUB( @OLD_CREATE, INTERVAL 1 DAY ) AS date_str,
0 AS count_str
FROM
( SELECT @OLD_CREATE := DATE_ADD( CURDATE( ), INTERVAL 1 DAY ) FROM t_admin_user LIMIT 7 ) t1) t2
LEFT JOIN
(SELECT
COUNT( t.PAY_ID ) AS countNumber,
SUM( CASE WHEN t.RESULT_STATUS = ( 1 ) THEN 1 ELSE 0 END ) AS successNumber,
SUM( t.PAY_AMOUNT ) AS orderAmount,
SUM( CASE WHEN t.RESULT_STATUS = ( 1 ) THEN t.PAY_AMOUNT ELSE 0 END ) AS successAmount,
SUM( CASE WHEN t.RESULT_STATUS = ( 1 ) THEN t.TIP ELSE 0 END ) AS tip,
CONVERT ( t.create_time, DATE ) AS date_str ,
SUM(CASE WHEN t.RESULT_STATUS = ( 1 ) THEN t.TOTAL_AMOUNT ELSE 0 END ) AS totalAmount
FROM
t_pay t
WHERE
t.FLAG = 0
GROUP BY
( CONVERT ( t.create_time, DATE ) ) ) t3
ON t2.date_str = t3.date_str
LEFT JOIN
(SELECT
SUM( u.AMOUNT ) AS topUpAmount,
SUM( u.TIP ) AS topUpTip,
CONVERT ( u.create_time, DATE ) AS date_str
FROM
t_top_up u
WHERE
u.FLAG = 0
GROUP BY
( CONVERT ( u.create_time, DATE ) ) ) t4
ON t3.date_str = t4.date_str
ORDER BY
date_str ASC执行SQL例子：

COALESCE ( t3.tip, 0 ) AS tip,
COALESCE ( t3.totalAmount, 0 ) AS totalAmount,
COALESCE ( t4.topUpAmount, 0 ) AS topUpAmount,
COALESCE ( t4.topUpTip, 0 ) AS topUpTip

SELECT
@OLD_CREATE := DATE_SUB( @OLD_CREATE, INTERVAL 1 DAY ) AS date_str,
0 AS count_str
FROM

查询一周时间的数据方法二：
tips：CURDATE( ) 当前日期可换成指定字符串日期
SELECT
