List , I am using Oracle enterprise edition 9.2.0.1.0 on windows.

I was trying to write the equivalent for a rollup , using grouping sets.

This works :
select dept_id, title, sum ( salary ) from s_emp where dept_id < 35 group by grouping sets ( (dept_id , title ) );

This also works :
select dept_id, title, sum ( salary ) from s_emp where dept_id < 35 group by grouping sets ( (dept_id , title ), dept_id );

However this locks up the session , oracle.exe shows a cpu usage of 99% and even a shutdown abort by the sysdba does not work. In fact no new users are able to log in , not even sysdbas.

select dept_id, title, sum ( salary ) from s_emp where dept_id < 35 group by grouping sets ( (dept_id , title ), dept_id, title );

Any ideas ?
