edit

To obtain the name of a column using a db link in Oracle 11g, you can use the following SQL query:

SELECT COLUMNNAME FROM ALLTABCOLUMNS@DBLINKNAME WHERE TABLENAME = 'TABLENAME' AND COLUMNID = COLUMN_NUMBER;

Replace the following placeholders in the query:

• DBLINKNAME: the name of the database link
• TABLE_NAME: the name of the table you want to get the column name from
• COLUMN_NUMBER: the number of the column you want to get the name for

Execute the query and it will return the name of the column you specified.
