Question

Supose I have a table with following kind of data:

Tab(id, myString)
1  A
2  B
3  C
...

I want to a SQL can return all one string for all values in Column myString. So the result I want looks like: “A, B, C”

If I don’t want to use cursor and stored procedure, is it possible sql to get such kind of result?

Answer 1

Declare @tbl table(ID nvarchar(1),[myString] nvarchar(100))
Insert into @tbl values(1,'A'); 
Insert into @tbl values(2,'B'); 
Insert into @tbl values(3,'C'); 
DECLARE @CSVList varchar(100)

SELECT @CSVList = COALESCE(@CSVList + ' , ', '') + 
   [myString]
FROM @tbl


SELECT @CSVList
