Question

我正在尝试运行一个选择查询，该查询将拉出所有计划在2300的meds作为日期范围。有没有办法可以将预定的日期/时间转换为一小时？这就是我到目前为止所做的：

SELECT DISTINCT USERCODE,
            TRANSACTIONID,
            ACTION,
            TRANSACTIONHOUR,
            SOURCE,
            RXNUMBER,
            DESCRIPTION,
            MASTERPATIENTID,
            FACILITYCODE,
            ADMINISTRATIONTIME
FROM    (   ABC.TL TL
       INNER JOIN
          ABC.S_VIEW S_VIEW
       ON (TL.RXNUMBER = S_VIEW.RXNUMBER))
   INNER JOIN
      ABC.PV PATIENTVISIT
   ON (TL.MASTERPATIENTID = PV.MASTERPATIENTID)
WHERE (TL.USERCODE NOT IN ('ABC'))
   AND (TL.ACTION IN ('A', 'DC'))
   AND (TL.TRANSACTIONHOUR BETWEEN to_date('2011-07-01 00:00:00', 'yyyy/mm/dd hh24:mi:ss') AND to_date('2011-09-30 23:59:59', 'yyyy/mm/dd hh24:mi:ss')

我希望查询在指定日期包含所有分配，但仅限于2300时。数据库是oracle 10g。

首先，您已使用不同格式的日期字符串和不同格式的格式。使其保持一致。

试试这个：

SELECT DISTINCT USERCODE,
            TRANSACTIONID,
            ACTION,
            TRANSACTIONHOUR,
            SOURCE,
            RXNUMBER,
            DESCRIPTION,
            MASTERPATIENTID,
            FACILITYCODE,
            ADMINISTRATIONTIME
FROM    (   ABC.TL TL
       INNER JOIN
          ABC.S_VIEW S_VIEW
       ON (TL.RXNUMBER = S_VIEW.RXNUMBER))
   INNER JOIN
      ABC.PV PATIENTVISIT
   ON (TL.MASTERPATIENTID = PV.MASTERPATIENTID)
WHERE (TL.USERCODE NOT IN ('ABC'))
   AND (TL.ACTION IN ('A', 'DC'))
   AND (TL.TRANSACTIONHOUR BETWEEN to_date('2011/07/01 00:00:00', 'yyyy/mm/dd hh24:mi:ss') AND to_date('2011/09/30 23:59:59', 'yyyy/mm/dd hh24:mi:ss')
   AND TO_CHAR(TL.TRANSACTIONHOUR, 'HH24MI') = '2300' --THIS IS THE NEW CONDITION

查询仅在特定时间发生的事务
