TSQL query to concatenate and remove common prefix

Hi

How does one compile a single string from the results of an SQL query.

E.g.

Table A
Column: Name
Row 0 : John
Row 1 : Sam
Row 2 : Kate

Resulting SQL query must return a single row with the result as a single string.

E.g.

"John, Sam, Kate"

Note: Using MS SQL 2005

This is what I usually use, just remove the table and add your own:

DECLARE @A
  TABLE ( Name VARCHAR(50) );

INSERT INTO @A ([Name]) VALUES ('John');
INSERT INTO @A ([Name]) VALUES ('Sam');
INSERT INTO @A ([Name]) VALUES ('Kate');

SELECT REPLACE((SELECT [Name] AS [data()]
  FROM @A
   FOR XML PATH('')
     ) , ' ', ', ') [Concatenated]

Should result in:

Concatenated

John, Sam, Kate
