选择一个值时查询乘以结果

Question

您好，我想显示产品、子材料、替代品、订单和日期。产品有 5 个子物料和 8 个不同日期的订单。我面临的问题是 Sub Materials 根据顺序乘以 8 倍。如何为一个重复值正确获取数据？感谢您的支持。

-查询如下

SELECT 
      B.BOMREC_CODE AS PRODUCT_CODE,
      S.NAME AS PRODUCT_NAME,
      B.BOMREC_MATERIALCODE AS SUB_MATERIAL,
      S1.NAME AS SUB_MATERIAL_NAME,
      B.BOMREC_ALTCODE AS ALTERNATIVE,
      (SIP.SF_QUANTITY - SIP.SF_NEWSHIPPED) AS OPEN_ORDERQT
      SIP.DLVDATE AS DELIERY_DATE
FROM BOMU01T B
LEFT JOIN STOCK00 S ON TRIM(S.CODE)=TRIM(B.BOMREC_CODE) 
LEFT JOIN STOCK00 S1 ON TRIM(S1.CODE)=TRIM(B.BOMREC_MATERIALCODE)
LEFT JOIN STOCK40T SIP ON TRIM(SIP.CODE)=TRIM(B.BOMREC_CODE)
WHERE B.BOMREC_CODE='2496802300'
ORDER BY 1 DESC

-STOCK00 Table 包含产品名称

-STOCK40T Table 持有订单。当我搜索“2496802300”的订单时，它显示如下

-我想要的应该是这样的

您似乎缺少 Group by 子句

试试这个：

SELECT 
      B.BOMREC_CODE AS PRODUCT_CODE,
      S.NAME AS PRODUCT_NAME,
      B.BOMREC_MATERIALCODE AS SUB_MATERIAL,
      S.NAME AS SUB_MATERIAL_NAME,
      B.BOMREC_ALTCODE AS ALTERNATIVE,
      (SIP.SF_QUANTITY - SIP.SF_NEWSHIPPED) AS OPEN_ORDERQT
      SIP.DLVDATE AS DELIERY_DATE
FROM BOMU01T B
LEFT JOIN STOCK00 S ON TRIM(B.BOMREC_CODE)= TRIM(S.CODE) 
AND TRIM(B.BOMREC_MATERIALCODE)=TRIM(S.CODE)
LEFT JOIN STOCK40T SIP ON TRIM(B.BOMREC_CODE)=TRIM(SIP.CODE)
WHERE B.BOMREC_CODE='2496802300'   

ORDER BY 7 DESC;
