如何在SQL Server中按部分列進行分組

我選擇了一些列，DATE列是datetime，我想只按收到標題的id和收到明細項目類別進行分組，但我運行的是SQL，我得到一個錯誤。如何成功運行？如何在SQL Server中按部分列進行分組

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 
    RECEIPT_ID, CATEGORY1

你得到什麼錯誤？ – Becuzz

CATEGORY2需要添加到羣組中，以便您的查詢能夠正常工作。 – isaace

@isaace以及日期（第一次選擇的列） – Eli

您必須組由所有非聚合列這是你的選擇條款的一部分。我修改了你的查詢來做到這一點 - 請參閱下文。
如果您只需要RECEIPT_ID和category1，需要GROUP BY，則不需要顯示其他兩列（日期和類別2），因爲它們已被合併。

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

如果你沒有上進行分組DATE或Category2，從查詢中刪除：

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

當使用GROUP BY SQL要求你SELECT條款各個領域要麼是：

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

我懷疑你所得到的錯誤裏面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.

必須GROUP BY其他列要從資金選擇（除），或者做一些複合查詢，以獲得您所需要

 group by DATE, RECEIPT_ID, CATEGORY1, CATEGORY2

每當你嘗試使用GROUP BY在你查詢你必須提到的所有其他列選擇比那些在你公司的其他數據GREGATE函數.Coz，GROUP BY基於選擇中的其他列進行。因此，您不能在Select CLAUSE中包含所有列。

按照您發佈的需求描述，即需要通過RECEIPT_ID CATEGORY2組和CATEGORY1和您的查詢應該像下面

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

如果你有聚合函數在SQL中，所有的非集合列必須出現在group by子句中。作爲變通，您可以在第一次SQL子句中使用，例如工會，這樣你就

SELECT RECEIPT_ID, CATEGORY1和資金，並在第二查詢你列的其餘
