Comma Separated List of all columns in the Database (Tablename | Column_names…)

Question

In SQL Server, I would like see Table_Name and all the Columns associated with that Table_Name in a database. So the Output should look like this:

      TABLE_N         


        

Answer 1

select name as TABLE_NAME,
       STUFF(COLUMN_NAME, 1, 1, '') AS COLUMN_NAME
from sys.tables t
CROSS APPLY 
( 
        SELECT 
            ',' + name AS [text()] 
        FROM 
            sys.columns c
        WHERE 
            c.object_id = t.object_id
        FOR XML PATH('') 
    ) o (COLUMN_NAME)
