Colonne délimitée par des tabulations SQL Colonne

Question

J'ai une colonne séparée par des tabulations dans un DB qui contient un champ d'en-tête et ses résultats associés. J'ai besoin d'aide avec une requête qui retournera ces données dans des lignes séparées basées sur une colonne IP. Voici un échantillon des données et aussi les résultats souhaités.

La requête ci-dessous donne ce résultat.

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 

Ceci est le résultat souhaité.

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 

Il s'agit des données copiées de la fenêtre de résultat SQL dans le Presse-papiers.

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

Créer des données d'échantillons

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') 

qui ressemble à ceci

Option 1 (avec des fonctions parse)

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 

retours

Option 2 (sans fonction parse)

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 

retours

Les fonctions Parse Si vous êtes intéressé

CREATE FUNCTION [dbo].[udf-Str-Parse] (@String varchar(max),@Delimiter varchar(10)) 
Returns Table 
As

    Cross Apply x.nodes('x') AS B(i)

Si vous utilisez SQL Server 2016, vous pouvez utiliser STRING_SPLIT()

Selon Aaron Bertrand c'est le moyen le plus rapide. Voir ce https://sqlperformance.com/2016/03/sql-server-2016/string-split

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'); 


;WITH CTE_Lines AS 
(
select ID, IP, a.ROWID , a.Lines from @YourTable 
    CROSS APPLY (
     SELECT 
      ROW_NUMBER() OVER (ORDER BY (SELECT 1)) AS ROWID, value Lines 
     FROM STRING_SPLIT(TabString, CHAR(13)) --Splits by new lines 
    ) a 
), CTE_Columns AS 
(
SELECT ID, IP, ROWID, b.ColsID, b.[Cols] FROM CTE_Lines 
    CROSS APPLY (
    SELECT 
     ROW_NUMBER() OVER (ORDER BY (SELECT 1)) AS ColsID, 
     value [Cols] 
     FROM STRING_SPLIT(Lines, CHAR(9)) --Splits by tabs 
    ) b 
    WHERE ROWID <> 1 --Removes the headers 
) 

SELECT ID, IP, [1] Package, [2] [Installed Version],[3] [Required Version] FROM 
(
    SELECT ID, IP, ROWID, ColsID, [Cols] FROM CTE_Columns 
) a 
PIVOT (MAX(a.Cols) FOR ColsId in ([1],[2],[3])) as pvt
