我试图在同一个查询中使用两次 UPDATE 来修改我的 TABLE 数据。你能解释一下我是怎么做到的吗？我收到以下代码的语法错误：

UPDATE HRBI SET HRBI.PayGroupLocationPayGroupCountryCode = IIF(HRBI.PayGroupLocationPayGroupCountryCode = 'DEU' AND HRBI.ManagementLevel = 'VP', 'DEU - Exec',
IIF(HRBI.PayGroupLocationPayGroupCountryCode = 'DEU' AND HRBI.ManagementLevel = 'SVP', 'DEU - Exec',
IIF(HRBI.PayGroupLocationPayGroupCountryCode = 'DEU' AND HRBI.ManagementLevel = 'FEL', 'DEU - Exec',
IIF(HRBI.PayGroupLocationPayGroupCountryCode = 'DEU' AND HRBI.ManagementLevel = 'DIR', 'DEU - Exec',
IIF(HRBI.PayGroupLocationPayGroupCountryCode = 'DEU' AND HRBI.ManagementLevel = 'SFL', 'DEU - Exec',
IIF(HRBI.PayGroupLocationPayGroupCountryCode = 'DEU' AND HRBI.ManagementLevel = 'STR', 'DEU - Exec',
IIF(HRBI.PayGroupLocationPayGroupCountryCode = 'DEU' AND HRBI.ManagementLevel = 'EVP', 'DEU - Exec', 
IIF(HRBI.WorkerID = '45' OR HRBI.WorkerID = '46' OR HRBI.WorkerID = '47' OR HRBI.WorkerID = '48' OR HRBI.WorkerID = '49' OR HRBI.WorkerID = '50' OR HRBI.WorkerID = '51', 'DEU - Exec', HRBI.PayGroupLocationPayGroupCountryCode))))))))
UPDATE SET HRBI.PayGroupCountryDesc = IIF(HRBI.PayGroupLocationPayGroupCountryCode = 'DEU - Exec', "Germany - Exec',HRBI.PayGroupCountryDesc);

我试图在另一个 UPDATE 的末尾添加一个额外的 UPDATE。另外，有没有办法在 Access SQL 中添加评论？谢谢！

那是疯狂的 SQL。

您的 set 语句实际上是说如果一行中的某些字段符合某些条件，则使 HRBI.PayGroupLocationPayGroupCountryCode = 'DEU - Exec' 的值保持原样。

“某些标准”应该作为 where 子句来实现！

所以它变成：

    UPDATE HRBI 
    SET HRBI.PayGroupLocationPayGroupCountryCode = 'DEU - Exec'
    WHERE 
    ( HRBI.PayGroupLocationPayGroupCountryCode = 'DEU' 
      AND 
      HRBI.ManagementLevel IN ('VP', 'SVP', ...etc ...)
    )
    OR
    (    HRBI.WorkerID = '45' OR HRBI.WorkerID = '46' OR HRBI.WorkerID = '47' 
      OR HRBI.WorkerID = '48' OR HRBI.WorkerID = '49' OR HRBI.WorkerID = '50' 
      OR HRBI.WorkerID = '51'
    );

请注意，您可能已经使用 HRBI.WorkerID IN (45,46, .....) 但我会留给您执行此操作...

你还需要重写这个：

    UPDATE SET HRBI.PayGroupCountryDesc =         
    IIF(HRBI.PayGroupLocationPayGroupCountryCode = 'DEU - Exec'
        , "Germany -   Exec'
        ,HRBI.PayGroupCountryDesc);

也许像这样嵌入第一个 SQL

    UPDATE HRBI 
    SET HRBI.PayGroupLocationPayGroupCountryCode = 'DEU - Exec'

       ,HRBI.PayGroupCountryDesc =  "Germany -   Exec'

    WHERE 
    ( HRBI.PayGroupLocationPayGroupCountryCode = 'DEU' 
      AND 
      HRBI.ManagementLevel IN ('VP', 'SVP', ...etc ...)
    )
    OR
    (    HRBI.WorkerID = '45' OR HRBI.WorkerID = '46' OR HRBI.WorkerID = '47' 
      OR HRBI.WorkerID = '48' OR HRBI.WorkerID = '49' OR HRBI.WorkerID = '50' 
      OR HRBI.WorkerID = '51'
    );

好的？
