可以创建一个正则表达式或其他东西来将文本分成列吗？

等于这张表：

| OldNumbers         | OldDeparture | OldArrival | OldDeparuteDate | NewNumbers         | NewDeparture | NewArrival | NewDeparuteDate | Type |                                                                    |

我尝试了一些查询，但总是在某些时候中断：

         SELECT TOP 100
          CHARINDEX(BD.Detail, ':')
        , SUBSTRING(BD.Detail,(CHARINDEX('0:0:0',BD.Detail) - 11),11) AS DepartureDateOLD 
        , SUBSTRING(BD.Detail,(CHARINDEX('0:0:0',BD.Detail) - 15),4) AS DepartureOLD 
        , SUBSTRING(BD.Detail,(CHARINDEX('0:0:0',BD.Detail) - 19),4) AS ArrivalOLD
        , SUBSTRING(BD.Detail,LEN(BD.Detail) - 20,11) AS DepartureDateNEW 
        , SUBSTRING(BD.Detail,LEN(BD.Detail) - 28,4) AS DepartureNEW 
        , SUBSTRING(BD.Detail,LEN(BD.Detail) - 24,4) AS ArrivalNEW
        , BD.CreatedDate
        , BD.Detail         
     FROM #FINAL_OLD BD

而且我不知道为什么charindex不工作0:0:0

编辑：

此查询根据日期值起作用：

     SELECT TOP 20
          PATINDEX('%0:0:0%', BD.Detail)
        , SUBSTRING(BD.Detail,(PATINDEX('%0:0:0%',BD.Detail) - 11),11) AS DepartureDateOLD 
        , SUBSTRING(BD.Detail,(PATINDEX('%0:0:0%',BD.Detail) - 15),4) AS DepartureOLD 
        , SUBSTRING(BD.Detail,(PATINDEX('%0:0:0%',BD.Detail) - 19),4) AS ArrivalOLD
        , SUBSTRING(BD.Detail,LEN(BD.Detail) - 20,11) AS DepartureDateNEW 
        , SUBSTRING(BD.Detail,LEN(BD.Detail) - 28,4) AS DepartureNEW 
        , SUBSTRING(BD.Detail,LEN(BD.Detail) - 24,4) AS ArrivalNEW
        , BD.CreatedDate
        , BD.Detail         
     FROM #FINAL_OLD BD

因为这条线G31450 /1129 GIG POA 11/4/2015 0:0:0 G31278 GIG POA 11/4/2015 0:0:0 MOVE运作良好。departureand总是有 3个arrival字符，但日期有时有 10、9 或 8 个字符，例如 1/1/2016 = 8 和 10/12/2016 = 10 个字符，我相信我必须考虑空格，但我不知道该怎么做。

尝试将您的 charindex 更改为patindex，看看是否可以帮助您。

SELECT TOP 100
          CHARINDEX(BD.Detail, ':')
        , SUBSTRING(BD.Detail,(PATINDEX('%0:0:0%',BD.Detail) - 11),11) AS DepartureDateOLD 
        , SUBSTRING(BD.Detail,(PATINDEX('%0:0:0%',BD.Detail) - 15),4) AS DepartureOLD 
        , SUBSTRING(BD.Detail,(PATINDEX('%0:0:0%',BD.Detail) - 19),4) AS ArrivalOLD
        , SUBSTRING(BD.Detail,LEN(BD.Detail) - 20,11) AS DepartureDateNEW 
        , SUBSTRING(BD.Detail,LEN(BD.Detail) - 28,4) AS DepartureNEW 
        , SUBSTRING(BD.Detail,LEN(BD.Detail) - 24,4) AS ArrivalNEW
        , BD.CreatedDate
        , BD.Detail         
     FROM #FINAL_OLD BD

我不知道是否有更好的方法，但它有效。

     SELECT

             ELSE SUBSTRING(BD.Detail,PATINDEX('%0:0:0%',BD.Detail) - 11,10)
          END) AS [DepartureDateOLD]
