Question

我正在MS Access中构建此数据库并创建此查询，它在Access中运行正常，但仅当我尝试将数据从Excel链接/源到它时才会提示此错误消息。

SELECT DISTINCT [Combined Risk - Current Mth].DUNS, 
    [Combined Risk - Current Mth].[Name Supplied], 
    [Combined Risk - Current Mth].[Combined Risk Rating], 
    [Combined Risk - Previous Mth].[Combined Risk Rating], 
    [Combined Risk - 4th Mth].[Combined Risk Rating], 
    [Combined Risk - 3rd Mth].[Combined Risk Rating], 
    [Combined Risk - 2nd Mth].[Combined Risk Rating], 
    [Combined Risk - 1st Mth].[Combined Risk Rating]
FROM (((([Combined Risk - Current Mth] 
LEFT JOIN [Combined Risk - 4th Mth] ON [Combined Risk - Current Mth].DUNS = [Combined Risk - 4th Mth].DUNS) 
LEFT JOIN [Combined Risk - 3rd Mth] ON [Combined Risk - Current Mth].DUNS = [Combined Risk - 3rd Mth].DUNS) 
LEFT JOIN [Combined Risk - 2nd Mth] ON [Combined Risk - Current Mth].DUNS = [Combined Risk - 2nd Mth].DUNS) 
LEFT JOIN [Combined Risk - 1st Mth] ON [Combined Risk - Current Mth].DUNS = [Combined Risk - 1st Mth].DUNS) 
LEFT JOIN [Combined Risk - Previous Mth] ON [Combined Risk - Current Mth].DUNS = [Combined Risk - Previous Mth].DUNS;

任何帮助都会非常感激。感谢

问题是由多个具有相同名称的列引起的。别名这些列以解决问题： -

SELECT DISTINCT [Combined Risk - Current Mth].DUNS, 
    [Combined Risk - Current Mth].[Name Supplied], 
    [Combined Risk - Current Mth].[Combined Risk Rating] as CRR_current, 
    [Combined Risk - Previous Mth].[Combined Risk Rating] as CRR_previous, 
    [Combined Risk - 4th Mth].[Combined Risk Rating] as CRR_4th, 
    [Combined Risk - 3rd Mth].[Combined Risk Rating] as CRR_3rd, 
    [Combined Risk - 2nd Mth].[Combined Risk Rating] as CRR_2nd, 
    [Combined Risk - 1st Mth].[Combined Risk Rating] as CRR_1st
FROM (((([Combined Risk - Current Mth] 
LEFT JOIN [Combined Risk - 4th Mth] ON [Combined Risk - Current Mth].DUNS = [Combined Risk - 4th Mth].DUNS) 
LEFT JOIN [Combined Risk - 3rd Mth] ON [Combined Risk - Current Mth].DUNS = [Combined Risk - 3rd Mth].DUNS) 
LEFT JOIN [Combined Risk - 2nd Mth] ON [Combined Risk - Current Mth].DUNS = [Combined Risk - 2nd Mth].DUNS) 
LEFT JOIN [Combined Risk - 1st Mth] ON [Combined Risk - Current Mth].DUNS = [Combined Risk - 1st Mth].DUNS) 
LEFT JOIN [Combined Risk - Previous Mth] ON [Combined Risk - Current Mth].DUNS = [Combined Risk - Previous Mth].DUNS;

链接到Excel时，语法错误（缺少运算符），查询运行正常
