子查询未与主查询连接

Question

下面的查询用于从数据库中检索报告中显示的记录。但是SENOKO和EUNOS列在每一行中显示重复的总数。这似乎子查询没有连接到主查询导致不进行过滤。

SELECT whbal.customer, customer.imp_license_no, customer.psq_level, 
   (SELECT SUM(CONVERT(DECIMAL(8,3),(CONVERT(DECIMAL(8, 3), whbal.qty_good) + CONVERT(DECIMAL(8, 3), whbal.qty_slack)) * CONVERT(DECIMAL(8, 3), whbal.std_weight) / 1000)) 
    FROM whbal WHERE warehouse='SKW') AS SENOKO
   (SELECT SUM(CONVERT(DECIMAL(8,3),(CONVERT(DECIMAL(8, 3), whbal.qty_good) + CONVERT(DECIMAL(8, 3), whbal.qty_slack)) * CONVERT(DECIMAL(8, 3), whbal.std_weight) / 1000)) 
    FROM whbal WHERE warehouse='EKW') AS EUNOS
FROM customer 
INNER JOIN whbal ON whbal.customer=customer.customer AND whbal.date_create<=@date1                   
INNER JOIN stktype ON whbal.stock_type=stktype.stock_type
WHERE whbal.customer BETWEEN @cust1 AND @cust2 AND whbal.stock_type=@type
GROUP BY whbal.customer, customer.customer, customer.imp_license_no, customer.psq_level

结果：

有谁知道问题和解决方案是什么，请提供建议和指导。 提前致谢

Answer 1

这可能是你想要的：

SELECT whbal.customer, customer.imp_license_no, customer.psq_level, 
    SUM(CASE WHEN warehouse='SKW' 
        THEN CONVERT(DECIMAL(8, 3), whbal.qty_good) 
           + CONVERT(DECIMAL(8, 3), whbal.qty_slack) 
         * CONVERT(DECIMAL(8, 3), whbal.std_weight)
        ELSE 0.0 END
       / 1000.0) AS SENOKO,
    SUM(CASE WHEN warehouse='EKW' 
        THEN CONVERT(DECIMAL(8, 3), whbal.qty_good) 
           + CONVERT(DECIMAL(8, 3), whbal.qty_slack) 
         * CONVERT(DECIMAL(8, 3), whbal.std_weight)
        ELSE 0.0 END
       / 1000.0) AS EUNOS
FROM customer 
INNER JOIN whbal ON whbal.customer=customer.customer AND whbal.date_create<=@date1                   
INNER JOIN stktype ON whbal.stock_type=stktype.stock_type
WHERE whbal.customer BETWEEN @cust1 AND @cust2 AND whbal.stock_type=@type
GROUP BY whbal.customer, customer.customer, customer.imp_license_no, customer.psq_level
