You can do it by joining against the table in the inline select. Like this:

SELECT
Table_Name,
ColumnList = SUBSTRING(
(SELECT
‘,’ + ISNULL(Column_Name,”)
FROM INFORMATION_SCHEMA.COLUMNS c
WHERE isc.TABLE_NAME = c.TABLE_NAME
FOR XML PATH(”))
,2,8000)
FROM INFORMATION_SCHEMA.COLUMNS isc
GROUP BY TABLE_NAME

Good Luck, Derek

Nice function, if you want to group this by a specified record, how do you handle this?
for example get all the order item id’s on a row with one Order ID
