MySql分组统计年度、季度、月度，周，天的数据

1、建表

DROP TABLE IF EXISTS `performance`;
CREATE TABLE `performance`  (
  `id` int(11) NOT NULL,
  `city` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
  `amout` decimal(10, 2) NULL DEFAULT NULL,
  `time` datetime(0) NULL DEFAULT NULL,
  PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Dynamic;

2、SQL按时间

-- 按年
  -- 第一种
SELECT
    DATE_FORMAT( time, '%Y' ) years,
    sum( amout ) amout 
FROM
    performance 
GROUP BY
    years 
ORDER BY
    years ASC;
  -- 第二种        
SELECT 
    YEAR ( time ) years,
    sum( amout ) amout 
FROM
    performance 
GROUP BY
    years 
ORDER BY
    years ASC;

-- 按季度
  -- 第一种
SELECT 
   CONCAT( YEAR ( time ), '年-第', FLOOR(( date_format( time, '%m' )+ 2 )/ 3 
        ), '季度' ) quarters,
   sum( amout ) amout 
FROM
    performance 
GROUP BY
    quarters 
ORDER BY
    quarters
  -- 第二种    
SELECT
    CONCAT(
        YEAR ( time ), '年-第',
    QUARTER ( time ), '季度') quarters,
    sum( amout ) amout 
FROM
    performance 
GROUP BY
    quarters
    order by quarters
    
-- 按月
  -- 第一种
SELECT
    DATE_FORMAT( time, '%Y-%m' ) months,
    sum( amout ) amout 
FROM
    performance 
GROUP BY
    months 
ORDER BY
    months ASC;
  -- 第二种        
SELECT
    CONCAT(
        YEAR ( time ),
        '-',
    MONTH ( time )) months,
    sum( amout ) amout 
FROM
    performance 
GROUP BY
    months 
ORDER BY
    months ASC;
        
-- 按周
  -- 第一种
SELECT
    DATE_FORMAT( time, '%x年-第%v周' ) weeks,
    sum( amout ) amout 
FROM
    performance 
GROUP BY
    weeks 
ORDER BY
    weeks ASC;   
  -- 第二种        
SELECT
    CONCAT(
        YEAR ( time ),
        '-',
    WEEK ( time ) + 1) weeks,
    sum( amout ) amout 
FROM
    performance 
GROUP BY
    weeks 
ORDER BY
    weeks ASC;

-- 按日
SELECT
    DATE_FORMAT( time, '%Y-%m-%d' ) days,
    sum( amout ) amout 
FROM
    performance 
GROUP BY
    days 
ORDER BY
    days ASC;

3、分城市按月查询 

-- 每个城市按月
SELECT
    city,
    DATE_FORMAT( time, '%Y-%m' ) months,
    sum( amout ) amout 
FROM
    performance 
GROUP BY
    city,
    months 
ORDER BY
    months ASC;
