I have 2 tables TableA, TableB (FK=TableAid)

I need to create a TableAView with a SINGLE column TableBList, that will list all the child of A seperated by a comma.

Is this possible ? It must me in a View (this is mandatory)

Thanks

its possible. you need to use a recursive CTE for that. see below

ouff seems complex,

can you give a sample of the statement using recursive CTE? to build a list of values seperated by a comma

I'm really lost, I'm really not a dba, i'm a developer.

What do you think about creating a funtion or a SP that will use COALESCE.

My view will then call the function or SP ....

Hi,
this is an examle of getting comma separated values in a column. update the query as per your requirement.

Alos u need not be an SQL Guru 2 use this

declare @table1 table (date datetime,Agrid int,chkId int,name varchar(18) )

insert into @table1 values('01/01/2008',102252271,100061, 'abc')
insert into @table1 values('12/31/2008',102252271,100842, 'Eli OldName')
insert into @table1 values('11-11-2004',102252271,100843, 'Eli OldName') ;

SELECT
CAST
(
(
SELECT name + ', '
FROM @table1
FOR XML PATH ('')
)
AS VARCHAR(MAX)
)
