If a HELP COLUMN statement contains a FROM clause, you can reference one or more tables, join indexes, and hash indexes in the same statement, as long as each column name is fully qualified (that is, preceded by the table name in the form “tablename.columnname”).

This does not apply when the referenced object is a data table name or an error table name.
