Question

如何从相同的表中为各个ID更新Opportunity_Record_Type，Opportunity_Division和Fiscal_Period？ PK是Opportunity_ID。

Answer 1

你可以做到

ANY DEFINED BY

这是dbfiddle演示

Answer 2

根据您的评论更新。我相信你需要一个内部联接来实现你想要做的事情。请将您的表名放在我写的＆＃39; YourTableName＆＃39;的任何地方。您将加入3个不同的子查询，这将为该特定ID提取该列的不同值。

UPDATE test 
SET Opportunity_Record_Type = join1.Opportunity_Record_Type,
    Opportunity_Division = join2.Opportunity_Division, 
    Fiscal_Period = join3.Fiscal_Period 
FROM 'YourTableName' test
    INNER JOIN (
        SELECT DISTINCT Opportunity_ID, Opportunity_Record_Type 
        FROM 'YourTableName' 
        WHERE Opportunity_Record_Type IS NOT NULL) join1 ON join1.Opportunity_ID = test.Opportunity_ID
    INNER JOIN (
        SELECT DISTINCT Opportunity_ID, Opportunity_Division 
        FROM 'YourTableName'
        WHERE Opportunity_Division IS NOT NULL) join2 ON join2.Opportunity_ID = test.Opportunity_ID
    INNER JOIN (SELECT DISTINCT Opportunity_ID, Fiscal_Period 
        FROM 'YourTableName' 
        WHERE Fiscal_Period IS NOT NULL) join3 ON join3.Opportunity_ID = test.Opportunity_ID

Answer 3

以下是您的示例。最好通过插入获得，当有重复键时更新值。我用虚拟数据填充它，因为我不知道有哪些有效输入。

INSERT INTO table (Opportunity_ID,Opportunity_Record_Type,Opportunity_Division,Fiscal_Period) 
VALUES (PK,1,1,1),
       (PK,1,1,1),
       (PK,1,1,1),
       (PK,1,1,1)
    ON DUPLICATE KEY UPDATE Opportunity_Record_Type=1,Opportunity_Division=1,...;

使用相同的表更新表中的列。
