I have the following table with following data as
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
This key value pair has to be split into and the value of each key has to be inserted into another table in the following fashion
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: when it finds column 'FutureMISBoundaryVersion' in tab1 then its value '2:21,5:50,4:55,7:80,9:33' will be split and its value is inserted in such a way that the corresponding value of key 2 i,e:21 will be inserted into FutureMIS-DURVersion column.
Similarly key 5's value 50 will be inserted into FutureMIS-BURVersion column and so on for other keys
when it finds column 'CurrentMISBoundaryVersion' then
'2:12,5:40,4:35,7:60,9:87' will be split and its value is inserted in such a way that the corresponding value of key 2 i,e:12 will be inserted into CurrentMIS-DURVersion column similarly key 5's 40 value will be inserted into DeviceMIS-YRTVersion column and so on for other columns of the source table.
The table structure may extend as I have shown only 4 source table column but logic for all the columns remain same
Very funky requirements to be honest. Please note solution below will work only in SQL Server 2016+ as I'm using JSON to parse the data. However you can write your own parser, in this case code will work in almost all versions of SQL Server.
Parse function:
CREATE FUNCTION dbo.ParseIt(@Type NVARCHAR(255),@Value NVARCHAR(MAX))
RETURNS @Parsed TABLE (Code NVARCHAR(255),Value NVARCHAR(255))
AS
BEGIN
INSERT INTO @Parsed(Code,Value)
SELECT @Type + '-' + m.Code + 'Version' AS [Code],p.[1] AS [Value]
FROM (
SELECT j.[key] AS [ID],i.[key],i.value
FROM OPENJSON('["' + REPLACE(@Value,',','","') + '"]') j
CROSS APPLY OPENJSON('[' + REPLACE(j.[value],':',',') + ']') i
) a
PIVOT(MAX(a.value) FOR a.[key] IN ([0],[1])) p
INNER JOIN ( VALUES
(2,'DUR')
,(4,'BUR')
,(5,'YRT')
,(7,'HAM')
,(9,'OAK')
) m(ID, Code) ON m.ID = p.[0]
;
RETURN;
END
Initial data:
DECLARE @Table TABLE (FutureMISBoundaryVersion NVARCHAR(MAX), CurrentMISBoundaryVersion NVARCHAR(MAX),FutureHAMBoundaryVersion NVARCHAR(MAX),CurrentHAMBoundaryVersion NVARCHAR(MAX));
INSERT INTO @Table(FutureMISBoundaryVersion,CurrentMISBoundaryVersion,FutureHAMBoundaryVersion,CurrentHAMBoundaryVersion)VALUES
('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')
;
The code:
SELECT COALESCE(p.[FutureMIS-OAKVersion],'') AS [FutureMIS-OAKVersion]
,COALESCE(p.[FutureMIS-HAMVersion],'') AS [FutureMIS-HAMVersion]
,COALESCE(p.[FutureMIS-DURVersion],'') AS [FutureMIS-DURVersion]
,COALESCE(p.[FutureMIS-BURVersion],'') AS [FutureMIS-BURVersion]
,COALESCE(p.[FutureMIS-YRTVersion],'') AS [FutureMIS-YRTVersion]
,COALESCE(p.[DeviceMIS-OAKVersion],'') AS [DeviceMIS-OAKVersion]
,COALESCE(p.[DeviceMIS-HAMVersion],'') AS [DeviceMIS-HAMVersion]
,COALESCE(p.[DeviceMIS-DURVersion],'') AS [DeviceMIS-DURVersion]
,COALESCE(p.[DeviceMIS-BURVersion],'') AS [DeviceMIS-BURVersion]
,COALESCE(p.[DeviceMIS-YRTVersion],'') AS [DeviceMIS-YRTVersion]
FROM (
SELECT f.Code,f.Value FROM @Table t CROSS APPLY dbo.ParseIt('FutureMIS',t.FutureMISBoundaryVersion) f
UNION ALL
SELECT f.Code,f.Value FROM @Table t CROSS APPLY dbo.ParseIt('DeviceMIS',t.CurrentMISBoundaryVersion) f
) a
PIVOT(MAX(a.Value) FOR a.Code IN ([DeviceMIS-BURVersion],[DeviceMIS-DURVersion],[DeviceMIS-HAMVersion],[DeviceMIS-OAKVersion]
,[DeviceMIS-YRTVersion],[FutureMIS-BURVersion],[FutureMIS-DURVersion],[FutureMIS-HAMVersion],[FutureMIS-OAKVersion]
,[FutureMIS-YRTVersion])) p
;
