无效的列名称“SENOKO”（SQL查询）

Question

我已经做了一个查询，我想添加一个“SENOKO”列，通过使用数据库中的字段来计算总和。如果我没有通过SENOKO进行分组，则重复的结果将显示在报告中。 为了避免重复记录，我当时就想，集团通过圣诺哥，但错误如下所示起来：

Invalid column name "SENOKO"

SELECT customer.customer, customer.imp_license_no, customer.psq_level, whbal.stock_type, (SELECT SUM((CONVERT(DECIMAL(9, 3), qty_good) + CONVERT(DECIMAL(9, 3), qty_slack)) * CONVERT(DECIMAL(9, 3), std_weight)/1000) FROM whbal WHERE warehouse='SKW')AS SENOKO 
FROM customer 
INNER JOIN whbal ON customer.customer=whbal.customer 
INNER JOIN stktype ON whbal.stock_type=stktype.stock_type 
WHERE customer.customer BETWEEN @cust1 AND @cust2 AND whbal.stock_type=@type 
GROUP BY customer.customer, customer.imp_license_no, customer.psq_level, whbal.stock_type, SENOKO 

任何人都可以请帮助？

Answer 1

SENOKO是派生列，所以您不能直接在GROUP BY子句中使用它。

使用此：

select * from (
SELECT customer.customer, customer.imp_license_no, customer.psq_level, whbal.stock_type, (SELECT SUM((CONVERT(DECIMAL(9, 3), qty_good) + CONVERT(DECIMAL(9, 3), qty_slack)) * CONVERT(DECIMAL(9, 3), std_weight)/1000) FROM whbal WHERE warehouse='SKW')AS SENOKO 
FROM customer 
INNER JOIN whbal ON customer.customer=whbal.customer 
INNER JOIN stktype ON whbal.stock_type=stktype.stock_type 
WHERE customer.customer BETWEEN @cust1 AND @cust2 AND whbal.stock_type=@type 
) as subquery 
GROUP BY subquery.customer, subquery.imp_license_no, subquery.psq_level, subquery.stock_type, Subquery.SENOKO
