How to convert SQL to PL/ORACLE

Question

Hi All,
I have the MSSQL SQL statement as below:
select column_name
from information_schema.key_column_usage
where constraint_name in ( select constraint_name
from information_schema.table_constraints
where table_name = 'cppuUTMSTATS' and constraint_type = 'PRIMARY KEY' )
order by ordinal_position;
I would like to have the equivalent PL statement for ORACLE.
Please help.
Thanks,
JP

The only possible problem I see is that you're trying
to order with a non selected column, you need that
the order by column is in the select to make it
work.Really?
SQL> select ename, job
  2  from emp
  3  order by empno
  4  ;
ENAME      JOB
SMITH      CLERK
ALLEN      SALESMAN
WARD       SALESMAN
JONES      MANAGER
MARTIN     SALESMAN
BLAKE      MANAGER
CLARK      MANAGER
SCOTT      ANALYST
KING       PRESIDENT
TURNER     SALESMAN
ADAMS      CLERK
JAMES      CLERK
FORD       ANALYST
MILLER     CLERK
14 rows selected.
SQL>I don't have a problem with ordering by columns that aren't selected.
