आप csv मान उत्पन्न करने के लिए STUFF का उपयोग कर सकते हैं। नीचे मैं सामान्य रूप से उपयोग करता हूं।
CREATE TABLE #Book
(
Id INT ,
NAME VARCHAR(100) ,
Description VARCHAR(100)
);
CREATE TABLE #BookReader
(
BookId INT ,
Name VARCHAR(100)
);
CREATE TABLE #BookVersion
(
BookId INT ,
Version VARCHAR(10)
);
INSERT INTO #Book ( Id ,
NAME ,
Description )
VALUES ( 1 , -- Id - int
'Book1' , -- NAME - varchar(100)
'Book 1 Title' -- Description - varchar(100)
) ,
( 2 , -- Id - int
'Book2' , -- NAME - varchar(100)
'Book 2 Title' -- Description - varchar(100)
) ,
( 3 , -- Id - int
'Book3' , -- NAME - varchar(100)
'Book 3 Title' -- Description - varchar(100)
) ,
( 4 , -- Id - int
'Book5' , -- NAME - varchar(100)
'Book 5 Title' -- Description - varchar(100)
);
INSERT INTO #BookReader ( BookId ,
Name )
VALUES ( 1 , -- BookId - int
'James' -- Name - varchar(100)
) ,
( 2 , -- BookId - int
'Stephane' -- Name - varchar(100)
) ,
( 2 , -- BookId - int
'Michael' -- Name - varchar(100)
);
INSERT INTO #BookVersion ( BookId ,
Version )
VALUES ( 1 , -- BookId - int
'v1' -- Version - varchar(10)
) ,
( 1 , -- BookId - int
'v2' -- Version - varchar(10)
) ,
( 2 , -- BookId - int
'v1' -- Version - varchar(10)
) ,
( 2 , -- BookId - int
'v2' -- Version - varchar(10)
) ,
( 2 , -- BookId - int
'v3' -- Version - varchar(10)
);
SELECT b.Id ,
LTRIM(STUFF(( SELECT ', ' + br1.[Name] AS [text()]
FROM #BookReader br1
WHERE br1.BookId = b.Id
FOR XML PATH('')) ,
1 ,
1 ,
'')) AS Reader ,
LTRIM(STUFF(( SELECT ', ' + Version
FROM #BookVersion bv1
WHERE bv1.BookId = b.Id
FOR XML PATH('')) ,
1 ,
1 ,
'')) AS version
FROM #Book b;
DROP TABLE #Book;
DROP TABLE #BookReader;
DROP TABLE #BookVersion;
परिणाम:
+----+--------------------+-------------+
| Id | Reader | Version |
+----+--------------------+-------------+
| 1 | James | v1, v2 |
| 2 | Stephane, Michael | v1, v2, v3 |
| 3 | NULL | NULL |
| 4 | NULL | NULL |
+----+--------------------+-------------+
