select 
    DATE as DATE, 
    RECEIPT_ID, 
    CATEGORY1, CATEGORY2, 
    SUM(CEILING(TOTAL_QTY/MEASURE.CONVERSION_QTY)) AS Qty, 
    SUM(ROUND(CEILING(TOTAL_QTY/MEASURE.CONVERSION_QTY) * 
     ROUND(MEASURE.LENGTH * MEASURE.WIDTH * MEASURE.HEIGHT/ 1000000.0, 9), 2)) AS cbm 
from 
    RECEIPT 
left join 
    MEASURE ON MEASURE.item = RECEIPT.ITEM

你得到什么错误？ – Becuzz

CATEGORY2需要添加到群组中，以便您的查询能够正常工作。 – isaace

@isaace以及日期（第一次选择的列） – Eli

您必须组由所有非聚合列这是你的选择条款的一部分。我修改了你的查询来做到这一点 - 请参阅下文。
如果您只需要RECEIPT_ID和category1，需要GROUP BY，则不需要显示其他两列（日期和类别2），因为它们已被合并。

SELECT 
     DATE as DATE, 
     RECEIPT_ID, 
     CATEGORY1, 
     CATEGORY2, 
     SUM(CEILING(TOTAL_QTY /MEASURE.CONVERSION_QTY)) as Qty, 
     SUM(Round(CEILING(TOTAL_QTY /MEASURE.CONVERSION_QTY)* Round(MEASURE.LENGTH * MEASURE.WIDTH * MEASURE.HEIGHT/ 1000000.0, 9), 2)) as cbm 
    from RECEIPT 
    left join MEASURE on MEASURE.item = RECEIPT.ITEM AND MEASURE.company = RECEIPT.COMPANY 
    WHERE MEASURE.QUANTITY_UM = 'ctn' 
    GROUP BY Date, RECEIPT_ID, CATEGORY1, CATEGORY2

如果你没有上进行分组DATE或Category2，从查询中删除：

select RECEIPT_ID, 
    CATEGORY1, 
    SUM(CEILING(TOTAL_QTY /MEASURE.CONVERSION_QTY)) as Qty, 
    SUM(Round(CEILING(TOTAL_QTY /MEASURE.CONVERSION_QTY)* Round(MEASURE.LENGTH * MEASURE.WIDTH * MEASURE.HEIGHT/ 1000000.0, 9), 2)) as cbm 
    from RECEIPT 
    left join MEASURE on MEASURE.item = RECEIPT.ITEM AND MEASURE.company = RECEIPT.COMPANY 
    WHERE MEASURE.QUANTITY_UM = 'ctn' 
    group by RECEIPT_ID, CATEGORY1

当使用GROUP BY SQL要求你SELECT条款各个领域要么是：

列入您的GROUP BY条款或
Containe聚合函数（例如，MIN，SUM等）

我怀疑你所得到的错误里面d是：

Column 'XXXXX' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.

必须GROUP BY其他列要从资金选择（除），或者做一些复合查询，以获得您所需要

 group by DATE, RECEIPT_ID, CATEGORY1, CATEGORY2

每当你尝试使用GROUP BY在你查询你必须提到的所有其他列选择比那些在你公司的其他数据GREGATE函数.Coz，GROUP BY基于选择中的其他列进行。因此，您不能在Select CLAUSE中包含所有列。

按照您发布的需求描述，即需要通过RECEIPT_ID CATEGORY2组和CATEGORY1和您的查询应该像下面

select 
    RECEIPT_ID, 
    CATEGORY1, 
    CATEGORY2, 
    SUM(CEILING(TOTAL_QTY /MEASURE.CONVERSION_QTY)) as Qty, 
    SUM(Round(CEILING(TOTAL_QTY /MEASURE.CONVERSION_QTY)* Round(MEASURE.LENGTH * MEASURE.WIDTH * MEASURE.HEIGHT/ 1000000.0, 9), 2)) as cbm 
    from RECEIPT 
    left join MEASURE on MEASURE.item = RECEIPT.ITEM AND MEASURE.company = RECEIPT.COMPANY 
    WHERE MEASURE.QUANTITY_UM = 'ctn' 
    group by RECEIPT_ID, CATEGORY1,CATEGORY2

如果你有聚合函数在SQL中，所有的非集合列必须出现在group by子句中。作为变通，您可以在第一次SQL子句中使用，例如工会，这样你就

SELECT RECEIPT_ID, CATEGORY1和资金，并在第二查询你列的其余
