SQL Server不正确的语法错误

Question

感谢您的帮助和阅读，我有以下查询，但我不明白为什么会出现此错误消息：

Msg 102，第15级，状态1，第1行
“价格”附近的语法不正确

我可以在独立查询中查询此数据列（批发价）。 我正在使用SQL Server 2005 Management Studio。

SELECT 
    ILE.[Location Code],
    ILE.SUM(Quantity) AS "Transfer Qty",
    PP.SUM(Wholesale Price) AS "Transfer Cost (HK)"
FROM 
    [DB].[dbo].[Company$Item Ledger Entry] ILE
INNER JOIN 
    [DB].[dbo].[Company$Purchase Price] PP ON ILE.[Item No_] = PP.[Item No_] 
                                           AND ILE.[Variant Code] = PP.[Variant Code]
WHERE
    ILE.[Entry Type] = '4' 
    AND ILE.[Location Code] NOT LIKE '%STAFF%' 
    AND ILE.[Location Code] NOT LIKE 'WHSPACKAGE' 
    AND ILE.[Location Code] NOT LIKE 'WHS'
GROUP BY
    ILE.[Location Code], ILE.[Quantity], PP.[Wholesale Price]
ORDER BY 
    [Location Code]

谢谢！

问候，帕特里克

Answer 1

在SQL中，必须转义包含特殊字符的名称-空格是特殊字符。 因为读取和编写具有很多方括号的代码很麻烦，所以一般建议避免使用此类名称。

就您而言，您缺少方括号：

SELECT ILE.[Location Code], ILE.Sum(Quantity) as "Transfer Qty",
       Sum(PP.[Wholesale Price]) as "Transfer Cost (HK)"
FROM [DB].[dbo].[Company$Item Ledger Entry] ILE INNER JOIN
     [DB].[dbo].[Company$Purchase Price] PP
     ON ILE.[Item No_] = PP.[Item No_] AND
        ILE.[Variant Code] = PP.[Variant Code]
Where ILE.[Entry Type] = '4' AND
      ILE.[Location Code] NOT LIKE '%STAFF%' AND
      ILE.[Location Code] NOT LIKE 'WHSPACKAGE' AND
      ILE.[Location Code] NOT LIKE 'WHS'
Group by ILE.[Location Code], ILE.[Quantity]
Order by [Location Code];

此外：

• PP.SUM()没有任何意义。 表别名与列名一起使用。
• 将批发价放入GROUP BY没有任何意义。 您想要汇总值，因此通常不会去那里。

检查此选择语句是否出错

SELECT 
    ILE.[Location Code],
    ILE.SUM(Quantity) AS "Transfer Qty",
    PP.SUM([Wholesale Price]) AS "Transfer Cost (HK)"--Error line

非常感谢！ 戈登！

两个SUM语句都应使用以下格式措辞：Sum（ILE。[Quantity]和Sum（PP。[Wholesale Price]）

    SELECT ILE.[Location Code], Sum(ILE.[Quantity]) as "Transfer Qty",
           Sum(PP.[Wholesale Price]) as "Transfer Cost (HK)"
      FROM [Dummy-28-Oct-2016].[dbo].[TEST ENV$Item Ledger Entry] ILE       
INNER JOIN [Dummy-28-Oct-2016].[dbo].[TEST ENV$Purchase Price] PP
        ON ILE.[Item No_] = PP.[Item No_] 
       AND ILE.[Variant Code] = PP.[Variant Code]
     Where ILE.[Entry Type] = '4' 
       AND ILE.[Location Code] NOT LIKE '%STAFF%' 
       AND ILE.[Location Code] NOT LIKE 'WHSPACKAGE' 
       AND ILE.[Location Code] NOT LIKE 'WHS'
  Group by ILE.[Location Code], ILE.[Quantity]
  Order by [Location Code];
