Did you try what was recommended in the SO question? What is your query? What is the result? Do you get an error?

SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME='YourTableName'

Try:

SQL

INSERT INTO dbo.DestinationTable (ColumnName)
SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.Columns
WHERE TABLE_NAME = 'SourceTable'

If I understand the question correctly, you want the list into a single column in a single row. If that is the case, consider the following:

SQL

WITH ColumnnList (List) AS (
   SELECT ';' + c.Column_Name
   FROM INFORMATION_SCHEMA.Columns c
   WHERE c.Table_Name = 'SOURCETABLENAME'
   FOR XML PATH ('')
) 
INSERT INTO TARGETTABLENAME (TARGETCOLUMNNAME)
SELECT SUBSTRING(a.List, 2, 99999)
FROM ColumnnList a

Just remember to change:

SOURCETABLENAME to the name of the table for which to list the columns
TARGETTABLENAME to the name of the table where you want to insert the data
TARGETCOLUMNNAME to the name of the target column in the target table
optionally change the separator to what you wish. I've used semicolon (;)
