Unlike MySQL, SQL Server doesn’t have a built-in function for this but you can still simulate it by using CROSS APPLY and FOR XML PATH('')

SELECT  a.Code, 
        SUBSTRING(d.[Name],1, LEN(d.[Name]) - 1) AddressList
FROM    
        (
            SELECT DISTINCT Code
            FROM TableA
        ) a
        CROSS APPLY
        (
            SELECT [Name] + ', ' 
            FROM TableA AS B 
            WHERE A.[Code] = B.[Code] 
            FOR XML PATH('')
        ) D ([Name]) ;
