i have a table with this structure
ID Word description
-------------------------------
1 book a lot of paper
2 book a thing
3 book an amazing thing
4 tv television
i want to convert this table to:
ID Word description
-------------------------------
1 book a lot of paper,a thing,an amazing thing
2 tv television
Note that :
-The maximum number of duplication is six
-I want to have a table without duplicate rows , i want to merge all duplicate rows to one row with all description values.
Thanks for your helps...
You can try this:
SELECT
ROW_NUMBER() OVER(ORDER BY (SELECT NULL)) AS Id,
*
FROM (
SELECT DISTINCT Word,
STUFF((SELECT ',' + description
FROM Your_Table
WHERE Word = T.Word
FOR XML PATH('')), 1, 1, '') AS description
FROM Your_Table T) AS A
