PLSQL does not support 'Sum Over Partition'

Question

I have something (and many obvious syntactical variations) like the following which works great in SQLPLUS but not in PLSQL:
select
table1.aField,
table2.bField,
sum (table1.type) over (partition by type)
from
table1, table2
where
aField = something;
PLSQL does not seem to like the "(" in from of the partition keyword.
I get the following PL/SQL error when I attempt to compile:
4/26 PLS-00103: Encountered the symbol "(" when expecting one of the following:
, from

Answer 1

What Oracle version are you running?
Is it Oracle8i?
Begining with Oracle9i, SQL parsers for SQL and PL/SQL were merged togather. Before 9i, many of the new features introduced in SQL were not recognized by the PL/SQL parser.
The following example works as expected on Oracle9i:
SQL> begin
  2    for rec in (select deptno, ename, sum(sal) over (partition by deptno)total  from scott.emp)
  3    loop
  4      dbms_output.put_line(rec.ename||' - '||rec.total) ;
  5    end loop ;
  6  end ;
