列旁边显示PRIMARY_MATERIAL。我目前正在使用UNION，它显示所有行（大约300行），但我真的只需要150行，并希望它显示在额外的列中。

SECONDARY_MATERIAL

Answer 1

我认为条件聚合会做你想要的。但是，您的查询很难遵循。我认为这是解决方案：

SELECT m.MaterialCode as MatCode,
       d.ShortDescription as ProcessArea, 
       MAX(CASE WHEN ShortDescription = N'PRIMARY_MATERIAL' THEN a.AttributeValue 
           END) as PrimaryMaterial_AttValue,
       MAX(CASE WHEN ShortDescription = N'SECONDARY_MATERIAL' THEN a.AttributeValue 
           END) as SecondaryMaterial_AttValue 
FROM DMI_Manu32.dbo.RM_Materials m INNER JOIN
     DMI_Manu32.dbo.RM_MRPAttributes a
     ON m.MaterialUID = a.MaterialUID AND m.InternalVersionNo = a.MaterialVersionNo INNER JOIN
     DMI_Manu32.dbo.RM_MRPAttributeDefinitions d
     ON d.MRPAttributeDefinitionsUID = a.MRPAttributeDefinitionsUID
WHERE m.ActiveTF = 1 AND a.ActiveTF = 1 AND
      d.ActiveTF = 1 AND
      m.DeletedTF = 0
GROUP BY m.MaterialCode, d.ShortDescription;

注意：

• 表别名使查询更容易阅读和写入。
• 一般情况下，不需要FROM子句中的括号。并且，INNER JOIN，永远不需要它们。括号通常会导致混淆。
• 无需在WHERE子句中重复条件（例如"RM_Materials".ActiveTF=1）。

Answer 2

只需一个查询：

AND "RM_MRPAttributeDefinitions"."ShortDescription" IN (N'PRIMARY_MATERIAL',N'SECONDARY_MATERIAL' )

认为可能会给你你想要的东西
