Sql 2 innerは他のデータの結果と結合します

Question

誰かが次のことを説明できますか？

SELECT results.`referentie`,products.`categorie`,products.`url`,products.`inkoopPrijs`,SUM(results.`stockverschil`) AS 'stockverschil' 
    FROM `results` results 
    INNER JOIN products 
    ON products.`referentie` = results.`referentie` 
    WHERE results.`datum` BETWEEN '2017-01-11' AND '2017-01-12' AND results.`referentie`= '1'  

結果は200（右量）のstockverschil結果

SELECT results.`referentie`,products.`categorie`,products.`url`,products.`inkoopPrijs`,sold.`winstPerProductPerDag`,SUM(results.`stockverschil`) AS 'stockverschil' 
    FROM `results` results 
    INNER JOIN products 
    ON products.`referentie` = results.`referentie` 
    INNER JOIN sold 
    ON sold.`referentie` = results.`referentie` 
    WHERE results.`datum` BETWEEN '2017-01-11' AND '2017-01-12' AND results.`referentie`= '1' 

結果は4800 のstockverschil結果は、私はINNER JOINのと間違って何かをやっているのでしょうか？

Answer 1

関係

がSUM(sold.winstPerProductPerDag)

SELECT results.`referentie`,products.`categorie`,products.`url`,products.`inkoopPrijs`,s.`winstPerProductPerDag`,SUM(results.`stockverschil`) AS 'stockverschil' 
FROM `results` results 
INNER JOIN products 
ON products.`referentie` = results.`referentie` 
INNER JOIN (select SUM(sold.`winstPerProductPerDag`) as `winstPerProductPerDag`, sold.`referentie` from sold group by sold.`referentie`) s on s.`referentie` = results.`referentie` 
WHERE results.`datum` BETWEEN '2017-01-11' AND '2017-01-12' AND results.`referentie`= '1'
