How to get primary key column in Oracle?

I need to get the name of the primary key column.

In the input, I only have the table name.

SELECT cols.table_name, cols.column_name, cols.position, cons.status, cons.owner
FROM all_constraints cons, all_cons_columns cols
WHERE cols.table_name = 'TABLE_NAME'
AND cons.constraint_type = 'P'
AND cons.constraint_name = cols.constraint_name
AND cons.owner = cols.owner
ORDER BY cols.table_name, cols.position;

Make sure that 'TABLE_NAME' is in upper case since Oracle stores table names in upper case.
