Using COALESCE function - concatenate many rows into a single text string output in SQL Server.

The following code is used to concatenate many rows into a single text string with comma separated using SQL Server COALESCE function.

My table format is like this:


I need output like this:

"RAM, GURU, Sundar, Shyam, Inba, Kalai"

I use the following query:

DECLARE @Names VARCHAR(8000)  
SELECT @Names = COALESCE(@Names + ', ', '') + Name FROM People
