SQL：聚合函数或GROUP BY

下面是一条sql语句和我收到的错误。我已经包含了来自两个表格的所有可能的字段，什么是错的？我想组，因为它不是在聚合函数或GROUP BY子句SQL：聚合函数或GROUP BY

SELECT TOP 20 
     ADMINSTATUS, CURRENCY, CUSTOMERID,  CUSTOMERMESSAGE, DELTIME, DELTOTAL, DISCOUNT, DISCOUNTCODE, 
     IP, ITEMDES, OPTIONS, ORDEREDID, ORDERTOTAL, 
     oi.ORDER_ID, o.ORDER_ID,  PAYMENTTYPE, PPRICE,  PRODID,  QTY, REASON,  SECURITYKEY, SHIPADDRESS1, 
     SHIPADDRESS2, SHIPADDRESS3, SHIPCITY, SHIPCOMPANY,  
     SHIPCOUNTRY, SHIPCOUNTY,  SHIPMETHOD, 
     SHIPNAME, SHIPPOSTCODE, STATUS,  STOCKCODE, SUBTOTAL, TAX, TAXABLE, TIMEDATE, TXAUTHNO, VENDORTXCODE, VPSTXID 
     FROM orderedItems oi 
     left join orders o on oi.order_id = o.order_id 


    Group by PRODID

如果您选择单独的列，它们都需要出现在GROUP BY子句中，除非它们是聚合函数。

在这里看到：http://msdn.microsoft.com/en-us/library/ms177673.aspx

例如

SELECT TOP 20 
     ADMINSTATUS, CURRENCY, CUSTOMERID,  CUSTOMERMESSAGE, DELTIME, DELTOTAL, DISCOUNT, DISCOUNTCODE, 
     IP, ITEMDES, OPTIONS, ORDEREDID, ORDERTOTAL, 
     oi.ORDER_ID, o.ORDER_ID,  PAYMENTTYPE, PPRICE,  PRODID,  QTY, REASON,  SECURITYKEY, SHIPADDRESS1, 
     SHIPADDRESS2, SHIPADDRESS3, SHIPCITY, SHIPCOMPANY,  
     SHIPCOUNTRY, SHIPCOUNTY,  SHIPMETHOD, 
     SHIPNAME, SHIPPOSTCODE, STATUS,  STOCKCODE, SUBTOTAL, TAX, TAXABLE, TIMEDATE, TXAUTHNO, VENDORTXCODE, VPSTXID 
     FROM orderedItems oi 
     left join orders o on oi.order_id = o.order_id 


    Group by ADMINSTATUS, CURRENCY, CUSTOMERID,  CUSTOMERMESSAGE, DELTIME, DELTOTAL, DISCOUNT, DISCOUNTCODE, 
     IP, ITEMDES, OPTIONS, ORDEREDID, ORDERTOTAL, 
     oi.ORDER_ID, o.ORDER_ID,  PAYMENTTYPE, PPRICE,  PRODID,  QTY, REASON,  SECURITYKEY, SHIPADDRESS1, 
     SHIPADDRESS2, SHIPADDRESS3, SHIPCITY, SHIPCOMPANY,  
     SHIPCOUNTRY, SHIPCOUNTY,  SHIPMETHOD, 
     SHIPNAME, SHIPPOSTCODE, STATUS,  STOCKCODE, SUBTOTAL, TAX, TAXABLE, TIMEDATE, TXAUTHNO, VENDORTXCODE, VPSTXID

感谢有道理现在:) – Prometheus

因为包含了所有归还物品由PRODID

列“orders.adminStatus”在选择列表中无效，正如它所说的那样，如果您使用的是GROUP BY，则需要按您要返回的字段进行分组，或者对其应用集合函数;例如：MAX，MIN等

SELECT TOP 20 
     ADMINSTATUS, CURRENCY, CUSTOMERID,  CUSTOMERMESSAGE, DELTIME, DELTOTAL, DISCOUNT, DISCOUNTCODE,  
     IP, ITEMDES, OPTIONS, ORDEREDID, ORDERTOTAL, 
     oi.ORDER_ID, o.ORDER_ID,  PAYMENTTYPE, PPRICE,  PRODID,  QTY, REASON,  SECURITYKEY, SHIPADDRESS1,  
     SHIPADDRESS2, SHIPADDRESS3, SHIPCITY, SHIPCOMPANY,  
     SHIPCOUNTRY, SHIPCOUNTY,  SHIPMETHOD, 
     SHIPNAME, SHIPPOSTCODE, STATUS,  STOCKCODE, SUBTOTAL, TAX, TAXABLE, TIMEDATE, TXAUTHNO, VENDORTXCODE, VPSTXID 
     FROM orderedItems oi 
     left join orders o on oi.order_id = o.order_id 



Group by   ADMINSTATUS, CURRENCY, CUSTOMERID,  CUSTOMERMESSAGE, DELTIME, DELTOTAL, DISCOUNT, DISCOUNTCODE,  
    IP, ITEMDES, OPTIONS, ORDEREDID, ORDERTOTAL, 
    oi.ORDER_ID, o.ORDER_ID,  PAYMENTTYPE, PPRICE,  PRODID,  QTY, REASON,  SECURITYKEY, SHIPADDRESS1,  
    SHIPADDRESS2, SHIPADDRESS3, SHIPCITY, SHIPCOMPANY,  
    SHIPCOUNTRY, SHIPCOUNTY,  SHIPMETHOD, 
    SHIPNAME, SHIPPOSTCODE, STATUS,  STOCKCODE, SUBTOTAL, TAX, TAXABLE, TIMEDATE, TXAUTHNO, VENDORTXCODE, VPSTXID

+1看起来我们都写了同样的东西，所以我想我必须为您的答案投票！ :-) –

@Dommer就一定意味着你有一个很好的答案:) – podiluska

我想这可能意味着我们都写SQL公平一点为生:-) –

既然你是PRODID分组，在选择列表中只PRODID应该存在，如果你想在选择列表中的任何其他列，应该用骨料finction给出像AVG（），MIN（） MAX（）等。

如果通过表中的所有可用列组，它等于

select distinct * from table

通常使用GROUP BY与集合函数一起拿到MIN，MAX等每个组在一张桌子上

你不链接不必显示你正在分组的场地，尽管在这种情况下这可能是一个红鲱鱼。 – podiluska

@podiluska：我的意思是，除了PRODID，你不能在选择列表中给出任何东西，但PRODID在选择列表中是可选的 –
