Question

我有一个查询的coldfusion查询，我无法在日期时间字段上正确排序。一组数据来自Oracle，另一组来自SQL Server 2012.它看起来像这样：

<cfquery name="SQLNotes" datasource="sql">
    SELECT dateNoteDate AS dateContactTime, 
        strNote,
        customerID
    FROM Notes
    order by dateContactTime desc
</cfquery>

<cfquery name="OracleNotes" datasource="oracle">
 SELECT TO_DATE ( CONCAT( CONCAT(DATE, ' '), TIME ),  'DD-MON-RR HH24:MI:SS')   AS "dateContactTime", 
 strNote,
 customerID
 FROM Notes
 order by dateContactTime desc
 </cfquery>


<cfquery name="AllNotes" dbtype="query">
 SELECT * FROM SQLNotes
 UNION
 SELECT * FROM OracleNotes
 ORDER BY dateContactTime desc
</cfquery>

它只是在SQL服务器注释之后抛出oracle注释，而不是对它们进行排序。我尝试过不同的东西，比如将时间加入到连接的时间戳上并按此排序。

我正在处理11行样本，当我使用queryName.dateContactTime [1] .getClass（）。name时，所有这些行都是数据类型java.sql.Timestamp。

以下是使用SELECT CAST(dateContactTime as TimeStamp) as ts order by ts desc

时排列顺序的时间
