[dba-SQLServer] List of fields in a table

I need to get a list of fields in a table in any database I want, in a stored procedure.  I have 
found this:

select COLUMN_NAME from INFORMATION_SCHEMA.COLUMNS where TABLE_NAME = 'tblOrderData'

but that only appears to work if you execute that from a query in the target database, whereas my 
stored procedure needs to take the database and table name as parameters and go get the list.

How can I get a list of fields in any table in any database, from a stored procedure saved in a 
"library" database?
