通过SQL查询更新MS Access中的两行

Question

如何在ms Access中使用一个查询更新两行...

我测试了曼尼代码，但没人为我工作。

UPDATE tblSecondProductItems 
SET secondProductItemLot = CASE
when secondProductItemCode = '616161911659' then 20
when secondProductItemCode = '611611965166' then 21
end
where secondProductItemCode in('616161911659','611611965166')

Answer 1

MS Access不支持CASE 。 您可以使用SWITCH() ：

UPDATE tblSecondProductItems 
    SET secondProductItemLot = SWITCH(secondProductItemCode = '616161911659', 20,
                                      secondProductItemCode = '611611965166', 21
                                     )
    WHERE secondProductItemCode IN ('616161911659','611611965166')

Answer 2

您可以尝试类似

UPDATE tblSecondProductItems 
CASE
    when secondProductItemCode == '616161911659' then secondProductItemCode = 20
    when secondProductItemCode == '611611965166' then secondProductItemCode = 21
END
WHERE secondProductItemCode in('616161911659','611611965166')
