如何在SQLServer数据库中使用函数/存储过程实现以下功能

sql sql-server

如何在SQLServer数据库中使用函数/存储过程实现以下功能,sql,sql-server,sql-function,Sql,Sql Server,Sql Function,我有下表，其中包含以下数据： Tab1 FutureMISBoundaryVersion CurrentMISBoundaryVersion FutureHAMBoundaryVersion CurrentHAMBoundaryVersion 2:21,5:50,4:55,7:80,9:33 2:12,5:40,4:35,7:60,9:87 2:52,5:90,4:75,7:30,9:57 2

我有下表，其中包含以下数据：

                                            Tab1
FutureMISBoundaryVersion  CurrentMISBoundaryVersion  FutureHAMBoundaryVersion  CurrentHAMBoundaryVersion 
2:21,5:50,4:55,7:80,9:33  2:12,5:40,4:35,7:60,9:87   2:52,5:90,4:75,7:30,9:57  2:42,5:60,4:95,7:70,9:37

必须将该键值对拆分为多个键，并且必须以以下方式将每个键的值插入到另一个表中

FutureMIS-OAKVersion |FutureMIS-HAMVersion |FutureMIS-DURVersion | FutureMIS-BURVersion| FutureMIS-YRTVersion |DeviceMIS-OAKVersion|DeviceMIS-HAMVersion |DeviceMIS-DURVersion| DeviceMIS-BURVersion| DeviceMIS-YRTVersion
              33     |              80     |            21       |            55       |  50                  | 87                 |  60                 |12                  |35                   | 40

i、 e：当它在tab1中找到“FutureMISBoundaryVersion”列时，它的值 “2:21,5:50,4:55,7:80,9:33”将被拆分，其值的插入方式应确保键2 i，e:21的相应值将插入FutureMIS DURVersion列

类似地，键5的值50将插入FutureMIS BURVersion列，以此类推，用于其他键

当它找到列“CurrentMISBoundaryVersion”时，则
“2:12,5:40,4:35,7:60,9:87”将被拆分，其值的插入方式是，键2 i，e:12的相应值将插入到CurrentMIS Durvision列中，类似地，键5的40值将插入到DeviceMIS YRTVersion列中，以此类推，用于源表的其他列

表结构可能会扩展，因为我只显示了4个源表列，但所有列的逻辑保持不变

以下查询将把逗号分隔的字符串

2:21,5:50,4:55,7:80,9:33

解析为单个组件

2:21

，

5:30

等。从那里，您可以使用类似的方法从

aa:bb

提取

bb

由于键值对的格式为

aa:bb

，因此可以使用

datepart（hour，'aa:bb'）

和

datepart（minute，'aa:bb'）

提取

aa

和

bb

老实说，这是非常时髦的要求。请注意，以下解决方案仅在SQL Server 2016+中有效，因为我使用JSON解析数据。然而，您可以编写自己的解析器，在这种情况下，代码将在几乎所有版本的SQL Server中工作

Squirrel:如果在键值对中找不到任何键，则会根据您的逻辑给出意外的o/p，即：不是这个'2:21,5:50,4:55,7:80,9:33'，假设我们有这样的'5:50,4:55,7:80,9:33'，那么整个解析过程都会出错。您是说第一个键总是
