Question

大家好我正在讨论为我的案例陈述总结saleytd的问题。我已经尝试在SalesYTD前放置一个sum函数，我得到的错误是sales旁边的synthax错误。我也尝试过salesytd进行分组，但这不起作用，因为它给了我这个错误列'PERSON.STATEPROVINCE.StateProvinceID'在选择列表中无效，因为它不包含在聚合函数或GROUP BY子句中。在这里我的查询如下。我的查询工作正常我只是得到它总和我的总数。

 USE AdventureWorks2014; 

 GO 

 SELECT  STATEPROVINCEID,A.NAME,A.COUNTRYREGIONCODE,(b.SALESYTD),  

 CASE 

 WHEN A.TerritoryID = '1' THEN 'WESTERN MARKET' 

 WHEN A.TerritoryID = '2' THEN 'NORTH EASTERN MARKET'

WHEN A.TerritoryID =  '3' THEN 'MID WESTERN MARKET' 

WHEN A.TerritoryID =  '4' THEN 'SOUTH WESTERN MARKET' 

WHEN A.TerritoryID =  '5' THEN 'SOUTH EASTERN MARKET' 
 ELSE 'OTHER' 

 END AS MARKET


FROM PERSON.STATEPROVINCE as A INNER JOIN SALES.SalesTerritory AS B

ON A.TerritoryID = B.TerritoryID 

WHERE A.CountryRegionCode = 'US'

Answer 1

如果您只想了解西南市场迄今为止的总销售年度，那么您可以针对该市场的SALESYTD列进行条件汇总：

SELECT SUM(CASE WHEN A.TerritoryID = '4' THEN b.SALESYTD ELSE 0 END) AS total_sales
FROM PERSON.STATEPROVINCE a
INNER JOIN SALES.SalesTerritory b
    ON a.TerritoryID = b.TerritoryID
WHERE a.CountryRegionCode = 'US'

如果您想要所有地区的总和，那么您可以使用GROUP BY：

SELECT a.TerritoryID, SUM(b.SALESYTD) AS total_sales
FROM PERSON.STATEPROVINCE a
INNER JOIN SALES.SalesTerritory b
    ON a.TerritoryID = b.TerritoryID
WHERE a.CountryRegionCode = 'US'
GROUP BY a.TerritoryID

Answer 2

我终于把一切都搞定了。感谢大家。这是我的查询

SELECT SUM(b.SALESYTD) AS TOTALSALES,

case

when a.TerritoryID = '1' then 'WESTERN MARKET' 

WHEN A.TERRITORYID = '2' THEN 'NORTH EASTERN MARKET' 

when a.TerritoryID = '3' then 'MID WESTERN MARKET' 

WHEN A.TerritoryID = '4' THEN 'SOUTH WESTERN MARKET' 

WHEN A.TERRITORYID = '5' THEN 'SOUTH EASTERN MARKET' 

else 'OTHER' 

end as MARKETS

FROM PERSON.STATEPROVINCE a

INNER JOIN SALES.SalesTerritory b

ON a.TerritoryID = b.TerritoryID

WHERE a.CountryRegionCode = 'US'

GROUP BY a.TerritoryID

总结每个市场的平衡
