SQL Split Tab Delimited Column

Question

I have a tab separated column in a DB that contains a header field and its related results. I need assistance with a query that will return that data in separate rows based on an IP column. Below is a sample of the data and also the desired results.

The below query yields this result.

DECLARE @Tmp TABLE (ID int Identity(1,1), IP nvarchar(255),Results NVARCHAR(max));
INSERT into @Tmp select top 1 ip, Results from MyTable where results like 'Package%'
select * from @Tmp

This is the desired result.

IP              Package      Installed Version          Required Version
10.48.8.28      nss          3.21.0-9.el7_2.x86_64      3.21.3-2.el7_3
10.48.8.28      nss-sysinit  3.21.0-9.el7_2.x86_64      3.21.3-2.el7_3
10.48.8.28      nss-tools    3.21.0-9.el7_2.x86_64      3.21.3-2.el7_3
10.48.8.28      nss-util     3.21.0-2.2.el7_2.x86_64    3.21.3-1.1.el7_3

This is the data as copied from the SQL result window to the clipboard.

ID  IP          Results
1   10.46.8.28  Package Installed Version   Required Version
                python  2.7.5-39.el7_2.x86_64   2.7.5-48.el7
                python-libs 2.7.5-39.el7_2.x86_64   2.7.5-48.el7

Answer 1

Create Sample Data

Declare @YourTable table (ID int,IP varchar(50),TabString varchar(max))
Insert Into @YourTable values
(1,'444.333.222.11','Package Installed Version  Required Version
nss 3.21.0-9.el7_2.x86_64   3.21.3-2.el7_3
nss-sysinit 3.21.0-9.el7_2.x86_64   3.21.3-2.el7_3
nss-tools   3.21.0-9.el7_2.x86_64   3.21.3-2.el7_3
nss-util    3.21.0-2.2.el7_2.x86_64 3.21.3-1.1.el7_3')

Which looks like this

Option 1 (with parse functions)

Select A.ID
      ,A.IP
      ,Package             = Pos1
      ,[Installed Version] = Pos2
      ,[Required Version]  = Pos3
 From  @YourTable A
 Cross Apply [dbo].[udf-Str-Parse](A.TabString,char(13)) B
 Cross Apply [dbo].[udf-Str-Parse-Row](B.RetVal,char(9)) C
 Where B.RetVal is not null and B.RetSeq>1

Returns

Option 2 (without parse function)

Select A.ID
      ,A.IP
      ,Package             = Pos1
      ,[Installed Version] = Pos2
      ,[Required Version]  = Pos3
 From  @YourTable A
 Cross Apply ( 
                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((Select replace(A.TabString,char(13),'§§Split§§') as [*] For XML Path('')),'§§Split§§','</x><x>')+'</x>' as xml).query('.')) as X
                Cross Apply x.nodes('x') AS B(i)
             ) B
 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)')))
                From  (Select Cast('<x>' + replace((Select replace(B.RetVal,char(9),'§§Split§§') as [*] For XML Path('')),'§§Split§§','</x><x>')+'</x>' as xml) as xDim) as X 
             ) C
 Where B.RetVal is not null and B.RetSeq>1

Returns

The Parse Functions if Interested

CREATE FUNCTION [dbo].[udf-Str-Parse] (@String varchar(max),@Delimiter varchar(10))
Returns Table 
As
Return (  
    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((Select replace(@String,@Delimiter,'§§Split§§') as [*] For XML Path('')),'§§Split§§','</x><x>')+'</x>' as xml).query('.')) as A 
    Cross Apply x.nodes('x') AS B(i)
);
