SQL Server - Add Row items as String with Comma Separated Values

Introduction:

In this article I will explain how to add row values as string with comma separated in SQL server.

Description:

In previous articles I explained Exception handling in SQL Server, SQL Query to read xml data file, SQL Query to get latest unique records by date, difference between function and stored procedures, joins in SQL Server, substring function in SQL server and many articles relating to SQL server. Now I will explain how to add row values as string with comma separated in SQL Server.

Here I will explain with one example for that I have one table UserDetails like as shown below

Now I want bind the username row values into single row with comma separated values like as shown below

If we want to concatenate one column row values into single row we need to write query like this

DECLARE @name NVARCHAR(MAX) SELECT @name = COALESCE(@name + ',', '') + UserName FROM UserDetails SELECT UserNames = @name

If you observe above query I used function COALESCE it returns the first non-null expression among its arguments.

We can concatenate rows in another way also

Another way

If we want to concatenate rows of column we can write query like as shown below

DECLARE @name NVARCHAR(MAX) SET @name='' SELECT @name = @name +','+UserName  FROM UserDetails SET @name = Substring(@name, 2, (len(@name))) SELECT @name as UserNames
