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)

Answer 2

Select TABLE_SCHEMA, TABLE_NAME
    , Stuff(
        (
        Select ', ' + C.COLUMN_NAME
        From INFORMATION_SCHEMA.COLUMNS As C
        Where C.TABLE_SCHEMA = T.TABLE_SCHEMA
            And C.TABLE_NAME = T.TABLE_NAME
        Order By C.ORDINAL_POSITION
        For Xml Path('')
        ), 1, 2, '') As Columns
From INFORMATION_SCHEMA.TABLES As T

As mentioned in comments, the above will include views. If you want to exclude views you can do the following:

Select T.TABLE_SCHEMA, T.TABLE_NAME
    , Stuff(
        (
        Select ', ' + C.COLUMN_NAME
        From INFORMATION_SCHEMA.COLUMNS As C
        Where C.TABLE_SCHEMA = T.TABLE_SCHEMA
            And C.TABLE_NAME = T.TABLE_NAME
        Order By C.ORDINAL_POSITION
        For Xml Path('')
        ), 1, 2, '') As Columns
From INFORMATION_SCHEMA.TABLES As T
    Left Join INFORMATION_SCHEMA.VIEWS As V
        On V.TABLE_SCHEMA = T.TABLE_SCHEMA
            And V.TABLE_NAME = T.TABLE_NAME
Where V.TABLE_NAME Is Null

Answer 3

Since your question mentions 'in a database', rather than use the information schema, I used the database:

select t.name, 
        STUFF ((
            select ',' + c.name
            from TEST_DB.sys.columns c
                join TEST_DB.sys.tables tt on tt.object_id = t.object_id and t.object_id = c.object_id
                join TEST_DB.sys.schemas s on tt.schema_id = s.schema_id
            order by t.name, c.column_id
            for xml path('')), 1, 1, '') as columns
from TEST_DB.sys.tables t
            where t.name = 'PutTableNameHere if you want to filter'

Leave the where clause out for all tables in a specific database.
