【问题描述】：

我目前在SQL中有一个很长的记录列表，由开始和结束分隔，中间我有重复值与加工名称。如何检索具有开始和结束日期以及关联名称的所有进程？我的实际查询是

    SELECT TOP 1000 id_prod,Descrizione,Parm0,LEFT(parm1, LEN(parm1)-20) as Azione ,convert(DateTime,right(parm1,19)) as Orario FROM INPUT
    where
        Parm0 = 'programstate' and (charindex('DNC_PRG_STS_FINISHED', Parm1) > 0)
             or
         Parm0 = 'programevent' and (charindex('dnc_prg_evt_started', Parm1) > 0 )
          or
          (
              parm0='ProgramName' and (charindex('USB0', Parm1) > 0)
                  )
    order by Orario Desc

id_prod	Parm0	Azione	Orario
2755686	ProgramName	\USB0\P99\PIASTRA M8.H	2021-12-06 11:46:48.000
2755683	ProgramName	\USB0\P99\PIASTRA M8.H	2021-12-06 11:46:38.000
2755681	ProgramName	\USB0\P99\PIASTRA M8.H	2021-12-06 11:46:37.000
2755676	ProgramName	\USB0\P99\PIASTRA M8.H	2021-12-06 11:46:36.000
2755672	ProgramName	\USB0\P99\PIASTRA M8.H	2021-12-06 11:46:33.000
2755666	ProgramState	DNC_PRG_STS_FINISHED	2021-12-06 11:42:33.000
2755663	ProgramName	\USB0\P99\PIASTRA M8.H	2021-12-06 11:42:23.000
2755662	ProgramName	\USB0\P99\PIASTRA M8.H	2021-12-06 11:42:22.000
2755659	ProgramName	\USB0\P99\PIASTRA M8.H	2021-12-06 11:42:21.000
2755644	ProgramState	DNC_PRG_EVT_STARTED	2021-12-06 11:22:33.000
2755641	ProgramName	\USB0\P99\PIASTRA M8.H	2021-12-06 11:22:33.000
2755633	ProgramName	\USB0\P99\PIASTRA M8.H	2021-12-06 11:22:13.000
2755631	ProgramName	\USB0\P99\PIASTRA M8.H	2021-12-06 11:21:23.000

编辑：谢谢@LukStorms，但这不是我需要的。开始、代码和结束组有数千个。我希望我最后有这样的清单

id_prod	Start	Finish	Lavorazione
1	2021-12-06 11:22:33.000	2021-12-06 11:42:33.000	\USB0\P99\PIASTRA M8.H
2	2021-12-06 11:11:43.000	2021-12-06 11:12:33.000	\USB0\P99\Lavorazione 11.H
3	2021-12-06 09:11:43.000	2021-12-06 11:42:33.000	\USB0\P99\Produzione 322.H
4	2021-12-02 11:11:43.000	2021-12-20 12:12:12.000	\USB0\P11\Piastra 19.H

我希望我很清楚。有成千上万个这样的过程，我需要把开头、结尾和中间的内容都放在中间，以便能够用表格使其可读

【问题讨论】：

是样本数据还是预期结果？无论如何我们都需要。
您使用的是哪个 dbms？（MS SQL Server？）
这是一小部分真实数据。我使用 MS SQL Server

标签： sql subquery

【解决方案1】：

您可以通过PATINDEX定位时间戳的位置。

示例 sn-p

declare @input table (
 id_prod int, 
 parm0 varchar(100),
 parm1 varchar(100)
);

insert into @input (id_prod, parm0, parm1) values
  (2755686, 'ProgramName',  '\USB0\P99\PIASTRA M8.H2021-12-06 11:46:48') 
, (2755644, 'ProgramEvent', 'DNC_PRG_EVT_STARTED 2021-12-06 11:22:33') 
, (2755666, 'ProgramState', 'DNC_PRG_STS_FINISHED 2021-12-06 11:42:33') 

SELECT *
FROM
(
    SELECT id_prod, parm0
    , LEFT(parm1, PATINDEX('%_20[0-9][0-9]-%', parm1)) AS Azione
    , TRY_CAST(SUBSTRING(parm1, PATINDEX('%20[0-9][0-9]-%', parm1), 19) AS DATETIME) AS Orario
    FROM @input
    WHERE parm0 IN ('programname', 'programevent', 'programstate')
      AND parm1 LIKE '%2021-12%'
) q
WHERE Orario BETWEEN '2021-12-01 00:00:00' AND '2021-12-06 23:59:59'

id_prod	parm0	Azione	Orario
2755686	ProgramName	\USB0\P99\PIASTRA M8.H	2021-12-06 11:46:48.000
2755644	ProgramEvent	DNC_PRG_EVT_STARTED	2021-12-06 11:22:33.000
2755666	ProgramState	DNC_PRG_STS_FINISHED	2021-12-06 11:42:33.000
