将SQL Server查询转换为MS Access 2003

Question

这是需要转换为MS Access 2003的SQL Server查询：

select  distinct u.ssn,u.[name],d.deptname,convert(varchar(12),c.checktime,103)Date,
 case  when convert(varchar(8),min(checktime),8)  between(select convert(varchar(8),checkintime1,8)startin
    from schclass_bak where schname like'Morning')and(select convert(varchar(8),checkintime2,8)endin
    from schclass_bak where schname like'Morning')
    then convert(varchar(8),min(checktime),8) else '0' end MOIN,
isnull(( select  max(convert(varchar(8),(checktime),8)) 
 from checkinOut g
 where (convert(varchar(8),(checktime),8))  between (select convert(varchar(8),checkouttime1,8)startOut
from schclass_bak where schname like'Morning') and (select convert(varchar(8),checkouttime2,8)endout
from schclass_bak where schname like'Morning') and g.USERID=u.userid and convert(varchar(12),g.checktime,103)=convert(varchar(12),c.checktime,103) ),'12:00')Mout,

case  when convert(varchar(8),max(checktime),8)  between(select convert(varchar(8),checkintime1,8)startin
    from schclass_bak where schname like'Afternoon')and(select convert(varchar(8),checkintime2,8)endin
    from schclass_bak where schname like'Afternoon')
    then convert(varchar(8),max(checktime),8) else '0' end AIN,
case when convert(varchar(8),max(checktime),8)  between(select convert(varchar(8),checkouttime1,8)startOut
    from schclass_bak where schname like'Afternoon')and(select convert(varchar(8),checkouttime2,8)endout
    from schclass_bak where schname like'Afternoon')
then convert(varchar(8),max(checktime),8) else '17:30' end AOUT

from checkinOut c inner join userinfo u on c.userid=u.userid
inner join departments d on u.defaultdeptid=d.deptid
where cast(convert(varchar(12),c.checktime)as smalldatetime)between '20170401' and '20170425' and u.ssn='50'
  group by  convert(varchar(12),c.checktime,103) ,u.ssn,u.[name],d.deptname,u.USERID

感谢您的帮助。 谢谢

Answer 1

我对您的格式进行了一些更改，但大多数情况下，我认为我做对了。

SELECT DISTINCT u.ssn,u.[name],d.deptname,Format(c.checktime,"dd/mm/yyyy") as [Date],
 iif( Format(min(checktime),"h:nn:ss") between (select Format(checkintime1,"h:nn:ss") as startin
    from schclass_bak where schname like 'Morning')and(select Format(checkintime2,"h:nn:ss") as endin
    from schclass_bak where schname like 'Morning')
    , Format(min(checktime),"h:nn:ss") 
    , '0') MOIN,
 isnull(( select  max(Format(checktime,"h:nn:ss")) 
    from checkinOut g where (Format(checktime,"h:nn:ss")  between (select Format(checkouttime1,"h:nn:ss") as startOut
    from schclass_bak where schname like 'Morning') and (select Format(checkouttime2,"h:nn:ss") as endout
    from schclass_bak where schname like 'Morning') and g.USERID=u.userid and Format(g.checktime,"dd/mm/yyyy")=Format(c.checktime,"dd/mm/yyyy") ),'12:00')Mout,
 iif( Format(max(checktime),"h:nn:ss")  between(select Format(checkintime1,"h:nn:ss") as startin
    from schclass_bak where schname like 'Afternoon') and (select Format(checkintime2,"h:nn:ss") as endin
    from schclass_bak where schname like 'Afternoon')
    , Format(max(checktime),"h:nn:ss") 
    , '0') AIN,
 iif( Format(max(checktime),"h:nn:ss") between(select Format(checkouttime1,"h:nn:ss") as startOut
    from schclass_bak where schname like 'Afternoon')and(select Format(checkouttime2,"h:nn:ss") as endout
    from schclass_bak where schname like 'Afternoon')
    , Format(max(checktime),"h:nn:ss") 
    , '17:30') AOUT

FROM checkinOut c inner join userinfo u on c.userid=u.userid
 INNER JOIN departments d on u.defaultdeptid=d.deptid
WHERE Format(c.checktime, "yyyymmdd") between '20170401' and '20170425' and u.ssn='50'
GROUP BY  Format(c.checktime,"dd/mm/yyyy"), u.ssn, u.[name], d.deptname, u.USERID

顺便说一句，这是一些SQL Server到MS Access的转换技巧：

• 结束时的情况-> iif（条件，真值部分，假值部分）
• 字段别名需要关键字“ As”。 示例：选择max（dollars）作为maxdollars
• 要将日期转换为varchar（具有格式）：Format（field，“ mask”）

SELECT DISTINCT u.ssn, u.name, Format(c.checktime,"dd/mm/yyyy") AS [Date], IIf(Format(Min(checktime),"h:nn:ss") Between (select Format(checkintime1,"h:nn:ss") as startin     from schclass where schname like 'Morning') And (select Format(checkintime2,"h:nn:ss") as endin     from schclass where schname like 'Morning'),Format(Min(checktime),"h:nn:ss"),'0') AS MOIN, IIf((select  max(Format(checktime,"h:nn:ss"))      from checkinOut g where Format(checktime,"h:nn:ss")  between (select Format(checkouttime1,"h:nn:ss") as startOut     from schclass  where schname like 'Morning') and (select Format(checkouttime2,"h:nn:ss") as endout     from schclass  where schname like 'Morning') and g.USERID=u.userid and Format(g.checktime,"dd/mm/yyyy")=Format(c.checktime,"dd/mm/yyyy")),(select  max(Format(checktime,"h:nn:ss"))      from checkinOut g where Format(checktime,"h:nn:ss")  between (select Format(checkouttime1,"h:nn:ss") as startOut     from schclass  where schname like 'Morning') and (select Format(checkouttime2,"h:nn:ss") as endout     from schclass  where schname like 'Morning') and g.USERID=u.userid and Format(g.checktime,"dd/mm/yyyy")=Format(c.checktime,"dd/mm/yyyy")),'12:00') AS Mout, IIf(Format(Max(checktime),"h:nn:ss") Between (select Format(checkintime1,"h:nn:ss") as startin     from schclass where schname like 'Afternoon') And (select Format(checkintime2,"h:nn:ss") as endin     from schclass where schname like 'Afternoon'),Format(Max(checktime),"h:nn:ss"),'0') AS AIN, IIf(Format(Max(checktime),"h:nn:ss") Between (select Format(checkouttime1,"h:nn:ss") as startOut     from schclass where schname like 'Afternoon') And (select Format(checkouttime2,"h:nn:ss") as endout     from schclass where schname like 'Afternoon'),Format(Max(checktime),"h:nn:ss"),'17:30') AS AOUT
