Question

My SQL Server view

SELECT     
   geo.HyperLinks.CatID, geo.Tags.Tag, geo.HyperLinks.HyperLinksID
FROM
   geo.HyperLinks LEFT OUTER JOIN
       geo.Tags INNER JOIN
       geo.TagsList ON geo.Tags.TagID = geo.TagsList.TagID ON geo.HyperLinks.HyperLinksID = geo.TagsList.HyperLinksID WHERE HyperLinksID = 1

returns these…

HyperLinksID CatID Tags
1            2     Sport
1            2     Tennis
1            2     Golf

How should I modify the above to have results like

HyperLinksID CatID TagsInOneRowSeperatedWithSpaceCharacter
1            2     Sport Tennis Golf

UPDATE: As Brad suggested I came up here…

DECLARE @TagList varchar(100)
SELECT @TagList = COALESCE(@TagList + ', ', '') + CAST(TagID AS nvarchar(100))
FROM TagsList
WHERE HyperLinksID = 1
SELECT @TagList

Now the result looks like

HyperLinksID CatID TagsInOneRowSeperatedWithSpaceCharacter
1            2     ID_OF_Sport ID_OF_Tennis ID_OF_Golf

And of course I have to combine the contents from the@TagList variable and the original SELECT statement…

Which means that I’ll have to wait for the holy SO bounty 🙁

If SQL, try this post:

Concatenating Row Values

If you want to try your hand at CLR code, there are examples of creating a custom aggregate function for concatenation, again, for MS SQL.

This post is pretty exhaustive with lots of ways to accomplish your goal.
