Question

I have this thing I don't know how to solve.

TABLE 1: ITEMS

ID | NO_ 
1 | SX1234
2 | SXABCD

TABLE 2: Text

Reffilename | RefKey | LanguageCode | ID | LineNumber | Txt1
Product | SX1234 | ENU | 2 | 0 | This is
Product | SX1234 | ENU | 2 | 1 | my text
Product | SX1234 | ENU | 2 | 2 | I want to come 
Product | SX1234 | ENU | 2 | 3 | out in one field
....

I can do this

SELECT i.[No]_, t.[Txt1] 
FROM ITEMS AS i
INNER JOIN 
TEXT AS t ON i.[no_] = t.RefKey
WHERE t.Reffilename = 'Prouduct' AND t.LanguageCode = 'ENU' AND t.ID = 2 AND i.[No_] = 'SX1234'

Thats give me this result.

SXI1234 | This is
SXI1234 | my text
SXI1234 | I want to come
SXI1234 | out in one field

But I want to merge the text, so my output will come:

SXI1234 | This is my text I Want to come out in one field

How do i solve this?

Answer 1

SELECT a.RefKey,Stuff((SELECT ''+ Txt1  FROM Text
where a.Id=b.Id
 FOR
 XML PATH(''),TYPE).value('text()[1]','nvarchar(max)'),1,2,N''
) As Text 
from ITEMS a
group by a.Id

Answer 2

Try using STUFF() function

SELECT i.[No]_, text= STUFF((
    SELECT ', ' + t.[Txt1] 
    FROM ITEMS AS a
    INNER JOIN 
    TEXT AS t ON i.[no_] = t.RefKey
    WHERE a.[No]_= i.[No]_
    FOR XML PATH, TYPE).value(N'.[1]', N'varchar(max)'), 1, 2, '')
FROM ITEMS AS i
GROUP BY i.[No]_

Answer 3

DECLARE @t1 TABLE (Id INT, Num CHAR (7))
INSERT INTO @t1
    VALUES (1, 'SX1234'), (2, 'SXABCD')
DECLARE @t2 TABLE (Reffilename Char(8), RefKey CHAR (7), LanguageCode  CHAR(4), ID INT, LineNumber INT, Txt1 VARCHAR(MAX))
INSERT INTO @t2
    VALUES ('Product', 'SX1234', 'ENU', 2, 0, 'This isa,
    ('Product', 'SX1234', 'ENU', 2, 1, 'my text'),
    ('Product', 'SX1234', 'ENU', 2, 2, 'I want to come'),
    ('Product', 'SX1234', 'ENU', 2, 3, 'out in one field')

SELECT DISTINCT RefKey, Result = STUFF((SELECT ' ' + t2.Txt1
                                FROM @t1 t1
                                JOIN @t2 t2 ON t1.Num = t2.RefKey 
                                FOR XML PATH('')), 1, 1, '' ) 
FROM @t2
