यह मानते हुए कि आप अधिक कुशल क्वेरी बनाने के लिए डेटा संरचनाओं को बदलने में असमर्थ हैं, यह काम करेगा:
--Populate sample data
SELECT 1 as key1, 2 as key2 INTO #tbl1
UNION ALL SELECT 1, 5
UNION ALL SELECT 1, 6
UNION ALL SELECT 1, 4
UNION ALL SELECT 1, 8
SELECT 1 as key1, 'Desc short' as shortkeydesc INTO #tbl2
SELECT 1 as key1, 'Desc a' as [description] INTO #tbl3
UNION ALL SELECT 1, 'Desc c'
UNION ALL SELECT 1, 'Desc aa'
UNION ALL SELECT 1, 'Desc tt'
--Combine data into semi-colon separated lists
SELECT
key1
,STUFF(
(
SELECT
';' + CAST(t2.key2 AS VARCHAR(10))
FROM #tbl1 t2
WHERE t2.key1 = tbl1.key1
FOR XML PATH('')
), 1, 1, ''
)
,STUFF(
(
SELECT
';' + tbl2.shortkeydesc
FROM #tbl2 tbl2
WHERE tbl2.key1 = tbl1.key1
FOR XML PATH('')
), 1, 1, ''
)
,STUFF(
(
SELECT
';' + tbl3.[description]
FROM #tbl3 tbl3
WHERE tbl3.key1 = tbl1.key1
FOR XML PATH('')
), 1, 1, ''
)
FROM #tbl1 tbl1
GROUP BY tbl1.key1
