如何重写用于Microsoft Access 2003中的TSQL查询：TSQL转换

Question

我想为Microsoft Access 2003重写此查询：

SELECT t1.PERSONID
       ,t1.CARDEVENTDATE
       ,MIN(t1.CARDEVENTTIME1) AS Intime
       ,MAX(t2.CARDEVENTTIME1) AS Outtime 

FROM (   SELECT PERSONID
                , CARDEVENTDATE
                , FUNCTIONKEY
                , CONVERT(VARCHAR(10), SUBSTRING(CARDEVENTTIME, 1, 2) + ':' + SUBSTRING(CARDEVENTTIME, 3, 2) + ':' + SUBSTRING(CARDEVENTTIME, 5, 2), 8) 
                 AS CARDEVENTTIME1  
         FROM T_CARDEVENT 
         WHERE      (FUNCTIONKEY = 'A')) AS t1 
         LEFT OUTER JOIN (SELECT PERSONID
                                 ,CARDEVENTDATE, CARDEVENTDAY, FUNCTIONKEY
                                 ,CONVERT(VARCHAR(10), SUBSTRING(CARDEVENTTIME, 1, 2) + ':' + SUBSTRING(CARDEVENTTIME, 3, 2) + ':' + SUBSTRING(CARDEVENTTIME, 5, 2), 8) 
                                  AS CARDEVENTTIME 
                      FROM T_CARDEVENT AS T_CARDEVENT_3) 
           AS t2 
           ON t1.PERSONID = t2.PERSONID 
           AND t1.CARDEVENTDATE = t2.CARDEVENTDATE   
           GROUP BY t1.PERSONID, t1.CARDEVENTDATE )

上面的方法在SQL Server中有效，但是在Access中，我尝试运行此查询。 它在convert产生错误 。

如何修改查询以适合Access 2003？ 什么是Access 2003中TSQL的Convert函数的合适等效项？

如果您使用与SQL Server兼容的语法，则下面的示例可能适用。

在t2中，您似乎缺少CARDEVENTTIME1，所以我将其添加为CARDEVENTTIME1。 您也似乎在末尾有一个额外的括号。

SELECT t1.PERSONID
       ,t1.CARDEVENTDATE
       ,MIN(t1.CARDEVENTTIME1) AS Intime
       ,MAX(t2.CARDEVENTTIME1) AS Outtime 

FROM (   SELECT PERSONID
                , CARDEVENTDATE
                , FUNCTIONKEY
                , CDate(Mid(CARDEVENTTIME, 1, 2) + ':' + Mid(CARDEVENTTIME, 3, 2) + ':' + Mid(CARDEVENTTIME, 5, 2)) 
                 AS CARDEVENTTIME1  
         FROM T_CARDEVENT 
         WHERE      (FUNCTIONKEY = 'A')) AS t1 
         LEFT OUTER JOIN (SELECT PERSONID
                                 ,CARDEVENTDATE, CARDEVENTDAY, FUNCTIONKEY
                                  , CDate(Mid(CARDEVENTTIME, 1, 2) + ':' + Mid(CARDEVENTTIME, 3, 2) + ':' + Mid(CARDEVENTTIME, 5, 2)) 
                                  AS CARDEVENTTIME1
                      FROM T_CARDEVENT AS T_CARDEVENT_3) 
           AS t2 
           ON t1.PERSONID = t2.PERSONID 
           AND t1.CARDEVENTDATE = t2.CARDEVENTDATE   
           GROUP BY t1.PERSONID, t1.CARDEVENTDATE 

Answer 2

您不能使用普通的Access函数Str（...）吗？

更新：这里没有Access可以尝试，但是没有参数告诉Access仅使用sql作为传递（不进行修改）吗？
