我有一个有帐号和卡号的数据库。我将这些匹配到一个文件,以将任何卡号更新为帐号,这样我只使用帐号。

我创建了一个将表链接到帐户/卡数据库的视图,以返回table ID和相关的帐号,现在我需要更新那些ID与account number匹配的记录。

这是Sales_Import表,其中的帐号字段需要更新:

LeadID AccountNumber
147 5807811235
150 5807811326
185 7006100100007267039

这是RetrieveAccountNumber表,我需要从这里更新:

LeadID AccountNumber
147 7006100100007266957
150 7006100100007267039

我尝试了下面的方法,但到目前为止运气都不佳:

UPDATE [Sales_Lead].[dbo].[Sales_Import] 
SET    [AccountNumber] = (SELECT RetrieveAccountNumber.AccountNumber 
                          FROM   RetrieveAccountNumber 
                          WHERE  [Sales_Lead].[dbo].[Sales_Import]. LeadID = 
                                                RetrieveAccountNumber.LeadID) 

它将卡号更新为帐号,但是帐号被NULL替换

下面是在SQL Server中对我有效的方法:

UPDATE [AspNetUsers] SET

[AspNetUsers].[OrganizationId] = [UserProfile].[OrganizationId],
[AspNetUsers].[Name] = [UserProfile].[Name]

FROM [AspNetUsers], [UserProfile]
WHERE [AspNetUsers].[Id] = [UserProfile].[Id];

其他回答

谢谢你的回复。但我找到了一个解决办法。

UPDATE Sales_Import 
SET    AccountNumber = (SELECT RetrieveAccountNumber.AccountNumber 
                          FROM   RetrieveAccountNumber 
                          WHERE  Sales_Import.leadid =RetrieveAccountNumber.LeadID) 
WHERE Sales_Import.leadid = (SELECT  RetrieveAccountNumber.LeadID 
                             FROM   RetrieveAccountNumber 
                             WHERE  Sales_Import.leadid = RetrieveAccountNumber.LeadID)  

试试这个:

UPDATE
    Table_A
SET
    Table_A.AccountNumber = Table_B.AccountNumber ,
FROM
    dbo.Sales_Import AS Table_A
    INNER JOIN dbo.RetrieveAccountNumber AS Table_B
        ON Table_A.LeadID = Table_B.LeadID 
WHERE
    Table_A.LeadID = Table_B.LeadID

下面是在SQL Server中对我有效的方法:

UPDATE [AspNetUsers] SET

[AspNetUsers].[OrganizationId] = [UserProfile].[OrganizationId],
[AspNetUsers].[Name] = [UserProfile].[Name]

FROM [AspNetUsers], [UserProfile]
WHERE [AspNetUsers].[Id] = [UserProfile].[Id];

这是Mysql和Maria DB最简单和最好的

UPDATE table2, table1 SET table2.by_department = table1.department WHERE table1.id = table2.by_id

注意:如果您遇到以下错误基于您的Mysql/Maria DB版本“错误代码:1175。您正在使用安全更新模式,并且您试图更新一个没有使用KEY列的WHERE的表。要禁用安全模式,请切换首选项中的选项。

然后像这样运行代码

SET SQL_SAFE_UPDATES=0;
UPDATE table2, table1 SET table2.by_department = table1.department WHERE table1.id = table2.by_id

如果以上答案不适合你,试试这个

Update Sales_Import A left join RetrieveAccountNumber B on A.LeadID = B.LeadID
Set A.AccountNumber = B.AccountNumber
where A.LeadID = B.LeadID
