單列到sqlserver中的行

Question

我想在Sql Server 2008中用';'分隔的單個表中將兩列分成兩行。請幫我解決這個問題。 列，如：

1;2;3;4;5;6;7; and a;b;c;d;e;f;g; 

輸出行，如：

1 a 
2 b 
3 c 
4 d 
5 e 
6 f 
7 g 

Answer 1

首先，你將需要一個分裂的功能，例如：

CREATE function [dbo].[Split] 
(
@string nvarchar(max), 
@delimiter nvarchar(20) 
) 
returns @table table 
(
    [Value] nvarchar(max) 
) 
begin 
declare @nextString nvarchar(max) 
declare @pos int, @nextPos int 

    set @nextString = '' 
    set @string = @string + @delimiter 

    set @pos = charindex(@delimiter, @string) 
    set @nextPos = 1 
    while (@pos <> 0) 
    begin 
     set @nextString = substring(@string, 1, @pos - 1) 

     insert into @table 
     (
      [Value] 
    ) 
     values 
     (
      @nextString 
    ) 

     set @string = substring(@string, @pos + len(@delimiter), len(@string)) 
     set @nextPos = @pos 
     set @pos = charindex(@delimiter, @string) 
    end 
    return 
end 

然後使用此代碼：

SELECT col1.Value as val1, 
     col2.Value as val2   
FROM 
    (SELECT Value, 
      ROW_NUMBER() over(order by value asc) as rownum 
    FROM (
     VALUES('1;2;3;4;5;6;7') 
     ) valued(X) CROSS APPLY 
      DBO.SPLIT(X,';') AS SPLITEDCOL) as col1 INNER JOIN 
    (SELECT Value, 
      ROW_NUMBER() over(order by value asc) as rownum 
    FROM (
     VALUES('A;B;C;D;E;F;G') 
     ) valued1(X) CROSS APPLY 
      DBO.SPLIT(X,';') AS SPLITEDCOL) as col2 
    ON COL1.rownum = col2.rownum 

如果你的兩列是從表中可以選擇它們的方式：

SELECT Value, 
     ROW_NUMBER() over(order by value asc) as rownum 
FROM YourTable CROSS APPLY 
     DBO.SPLIT(YourColumnName,';') AS SPLITEDCOL 

注意1個集使用交叉申請是必要的，你想在返回行

希望這每個列有助於

Answer 2

Declare @ID as Varchar(1000) 
set @ID = '1;2;3;4;5;6;7;' 
SELECT 
LTRIM(RTRIM(m.n.value('.[1]','varchar(8000)'))) AS ID 
FROM 
(
SELECT CAST('<XMLRoot><RowData>' + REPLACE(@ID,';','</RowData><RowData>') + '</RowData></XMLRoot>' AS XML) AS x 
)t 
CROSS APPLY x.nodes('/XMLRoot/RowData')m(n) 

Answer 3

DECLARE @Table1 TABLE(ID INT, Value char) 
INSERT INTO @Table1 VALUES (1,'a'),(1,'b'),(1,'c'),(1,'d') 


SELECT STUFF((SELECT '; ' + CAST(ID AS VARCHAR(10)) [text()] 
     FROM @Table1 
     WHERE ID = t.ID 
     FOR XML PATH(''), TYPE) 
     .value('.','NVARCHAR(MAX)'),1,2,' ') ID 
     ,STUFF((SELECT '; ' + CAST(Value AS VARCHAR(10)) [text()] 
     FROM @Table1 
     WHERE ID = t.ID 
     FOR XML PATH(''), TYPE) 
     .value('.','NVARCHAR(MAX)'),1,2,' ') value 
FROM @Table1 t
