Om du har ett maximalt antal kolumner, lite XML i ett CROSS APPLY.
Om du är okänd måste du gå DYNAMISK.
Exempel
Declare @YourTable Table ([ID] varchar(50),[SomeCol] varchar(50))
Insert Into @YourTable Values
(1,'[Key1:Value1:Value2:Value3:Value4:Value5]')
,(2,'[Key2:Value1:Value2:Value3:Value4:Value5]')
,(3,'[Key3:Value1:Value2:Value3:Value4:Value5]')
Select A.ID
,B.*
From @YourTable A
Cross Apply (
Select Pos1 = ltrim(rtrim(xDim.value('/x[1]','varchar(max)')))
,Pos2 = ltrim(rtrim(xDim.value('/x[2]','varchar(max)')))
,Pos3 = ltrim(rtrim(xDim.value('/x[3]','varchar(max)')))
,Pos4 = ltrim(rtrim(xDim.value('/x[4]','varchar(max)')))
,Pos5 = ltrim(rtrim(xDim.value('/x[5]','varchar(max)')))
,Pos6 = ltrim(rtrim(xDim.value('/x[6]','varchar(max)')))
,Pos7 = ltrim(rtrim(xDim.value('/x[7]','varchar(max)')))
,Pos8 = ltrim(rtrim(xDim.value('/x[8]','varchar(max)')))
,Pos9 = ltrim(rtrim(xDim.value('/x[9]','varchar(max)')))
From (Select Cast('<x>' + replace(replace(replace(SomeCol,'[',''),']',''),':','</x><x>')+'</x>' as xml) as xDim) as A
) B
Returer
ID Pos1 Pos2 Pos3 Pos4 Pos5 Pos6 Pos7 Pos8 Pos9
1 Key1 Value1 Value2 Value3 Value4 Value5 NULL NULL NULL
2 Key2 Value1 Value2 Value3 Value4 Value5 NULL NULL NULL
3 Key3 Value1 Value2 Value3 Value4 Value5 NULL NULL NULL
Jag borde lägga till ltrim(rtrim(...))
är valfritt och varchar(max)
är min demonstrativa standard.
Declare @S varchar(max)='
[Key1:Value1:Value2:Value3:Value4:Value5]
[Key2:Value1:Value2:Value3:Value4:Value5]
[Key3:Value1:Value2:Value3:Value4:Value5]
'
Select B.*
From (
Select RetSeq = Row_Number() over (Order By (Select null))
,RetVal = LTrim(RTrim(B.i.value('(./text())[1]', 'varchar(max)')))
From (Select x = Cast('<x>' + replace(@S,char(13)+char(10),'</x><x>')+'</x>' as xml).query('.')) as A
Cross Apply x.nodes('x') AS B(i)
) A
Cross Apply (
Select Pos1 = ltrim(rtrim(xDim.value('/x[1]','varchar(max)')))
,Pos2 = ltrim(rtrim(xDim.value('/x[2]','varchar(max)')))
,Pos3 = ltrim(rtrim(xDim.value('/x[3]','varchar(max)')))
,Pos4 = ltrim(rtrim(xDim.value('/x[4]','varchar(max)')))
,Pos5 = ltrim(rtrim(xDim.value('/x[5]','varchar(max)')))
,Pos6 = ltrim(rtrim(xDim.value('/x[6]','varchar(max)')))
,Pos7 = ltrim(rtrim(xDim.value('/x[7]','varchar(max)')))
,Pos8 = ltrim(rtrim(xDim.value('/x[8]','varchar(max)')))
,Pos9 = ltrim(rtrim(xDim.value('/x[9]','varchar(max)')))
From (Select Cast('<x>' + replace(replace(replace(RetVal,'[',''),']',''),':','</x><x>')+'</x>' as xml) as xDim) as A
) B
Where A.RetVal is not null
