I have the following table

ShoeID Shoe
1 A
2 B
1 A
1 F
2 C
4 A
4 A
1 C

How can I create a query that concatenates the shoe (without spaces) to one field for each shoeid e.g.
ShoeID Shoe
1 AAFC
2 BC
4 AA

SELECT ShoeID,
(SELECT '' + Shoe FROM table WHERE ShoeID = t.ShoeID FOR XML PATH(''))
FROM (SELECT DISTINCT ShoeID FROM table) t

Hi Visakh,

Thanks for the reply, please could you explain how this query works? I have tried reading about XML path but cannot figure out how the query works

Thanks

The subquery using FOR XML PATH generates a xml string with dummy node name which in effect will give you ling list of shoes. You take distinct of ShoeID as a separate derived table with alias as t and then pass these ids to inner query to get long list of shoes associated to each of the id values
