Question

执行时我面临的以下查询：

IErrorInfo.GetDescription 失败，出现 E_FAIL(0x80004005)。

连接 MS Access 数据库。当我在 SQL Server 中执行相同操作时，它可以正常工作，但不能用于 MS Access 数据库。任何人都可以帮助解决这个问题。

select [EmpName],EmpMaster.EmpCodeDisplay,Transactions.CardNo,
case when CONTROLLERS.ControllerName = 'Level0Entry' then 'Reception' when CONTROLLERS.ControllerName = 'LevelBCiscoNSNRx' then 'Basement' 
else CONTROLLERS.ControllerName end as ControllerName,aDateTime from Transactions 
inner join CONTROLLERS on Transactions.ControllerNo = CONTROLLERS.ControllerNo  
inner join EmpMaster on Transactions.EmpCode = EmpMaster.EmpCode 
where transactions.ControllerNo in ('7','9') and aDateTime between '1/28/2015 05:45:00.000' and '1/28/2015 23:59:00.000' 
and transactions.EmpCode <> '0'   and Transactions.CardNo in (select CardNo from Transactions 
where transactions.ControllerNo in ('7','9') and transactions.EmpCode <> '0' and aDateTime between '1/28/2015 05:45:00.000' and '1/28/2015 23:59:00.000' 
 group by Transactions.CardNo having COUNT(Transactions.CardNo) < 2 )  order by aDateTime asc
