sql多重连接查询和多重计数

Question

我想从我的产品销售表中统计（当前日销售和每月销售和季度销售），单独所有三个查询都工作正常，但我想分成一个。

SELECT tm.internal_name AS model_number, tm.item_description, tm.mrp, tm.asin, COUNT(product_serial_no) AS `S_FTD` FROM register_product_claim INNER JOIN tbl_model tm ON register_product_claim.model_number = tm.asin WHERE retailer_code = '9017' AND register_product_claim.dt = '2016-08-04' GROUP BY tm.asin ORDER BY register_product_claim.dt DESC LIMIT 0 , 30 

这是对于当前日期

2）这是每月出卖计数

SELECT tm.internal_name AS model_number, tm.item_description, tm.mrp, tm.asin, COUNT(product_serial_no) AS `S_MTD` FROM register_product_claim INNER JOIN tbl_model tm ON register_product_claim.model_number = tm.asin WHERE retailer_code = '9017' AND MONTH(register_product_claim.dt) = '08' GROUP BY tm.asin ORDER BY register_product_claim.dt DESC LIMIT 0 , 30 

3）这是本季度

SELECT tm.internal_name AS model_number, tm.item_description, tm.mrp, tm.asin, COUNT(product_serial_no) AS `S_QTD` 
FROM register_product_claim INNER JOIN tbl_model tm ON register_product_claim.model_number = tm.asin WHERE retailer_code = '9017' 
AND (MONTH(register_product_claim.dt) = '08' 
OR MONTH(register_product_claim.dt) = '07' 
OR MONTH(register_product_claim.dt) = '06' 
) GROUP BY tm.asin ORDER BY register_product_claim.dt DESC 
LIMIT 0 , 30

所需输出为

model_number | item_description | mrp | asin | S_FTD | S_MTD | S_QTD

尝试这样的事情

SELECT 
    stat1.model_number model_number, 
    stat1.item_description item_description, 
    stat1.mrp mrp, 
    stat1.asin asin, 
    stat1.S_FTD S_FTD, 
    stat2.S_MTD S_MTD, 
    stat3.S_QTD S_QTD 
FROM 
    (SELECT 
     tm.internal_name AS model_number, 
      tm.item_description, 
      tm.mrp, 
      tm.asin, 
      COUNT(product_serial_no) AS `S_FTD` 
    FROM 
     register_product_claim 
    INNER JOIN tbl_model tm ON register_product_claim.model_number = tm.asin 
    WHERE 
     retailer_code = '9017' 
      AND register_product_claim.dt = '2016-08-04' 
    GROUP BY tm.asin 
    ORDER BY register_product_claim.dt DESC 
    LIMIT 0 , 30) stat1 
     JOIN 
    (SELECT 
     tm.internal_name AS model_number, 
      COUNT(product_serial_no) AS `S_MTD` 
    FROM 
     register_product_claim 
    INNER JOIN tbl_model tm ON register_product_claim.model_number = tm.asin 
    WHERE 
     retailer_code = '9017' 
      AND MONTH(register_product_claim.dt) = '08' 
    GROUP BY tm.asin 
    ORDER BY register_product_claim.dt DESC 
    LIMIT 0 , 30) stat2 ON stat1.model_number = stat2.model_numer 
     JOIN 
    (SELECT 
     tm.internal_name AS model_number, 
      COUNT(product_serial_no) AS `S_QTD` 
    FROM 
     register_product_claim 
    INNER JOIN tbl_model tm ON register_product_claim.model_number = tm.asin 
    WHERE 
     retailer_code = '9017' 
      AND (MONTH(register_product_claim.dt) = '08' 
      OR MONTH(register_product_claim.dt) = '07' 
      OR MONTH(register_product_claim.dt) = '06') 
    GROUP BY tm.asin 
    ORDER BY register_product_claim.dt DESC 
    LIMIT 0 , 30) stat3 ON stat1.model_number = stat3.model_number
