更新查询 - MS Access 中同一字段的多个条件

Question

我是 MS Access 脚本的新手，想在一个实例中执行多个查询。我需要这个查询来根据 SET 标准更新记录。以下是我到目前为止所拥有的。

UPDATE Inspections SET Inspections.Surveyed_By = "TDG/DT"
WHERE Inspections.Surveyed_By="TDG/DavidT";
OR
UPDATE Inspections SET Inspections.Surveyed_By = "TDG/RW"
WHERE Inspections.Surveyed_By="TDG/RobbieW"

Answer 1

这是您要找的吗？

UPDATE Inspections 
SET Surveyed_By = IIF(Surveyed_By = 'TDG/DavidT', 'TDG/DT', 'TDG/RW')
WHERE Surveyed_By IN ('TDG/DavidT', 'TDG/RobbieW');

Answer 2

您可以使用Switch

UPDATE Inspections 
SET Surveyed_By = Switch(
        Surveyed_By = "TDG/DavidT", "TDG/DT",
        Surveyed_By = "TDG/RobbieW" , "TDG/RW" );
WHERE 
    Surveyed_By = "TDG/DavidT"
    OR Surveyed_By = "TDG/RobbieW"
