Re: avoid dynamic SQL

Alex,

Can you give some examples of the formula, please?
what version are you on? In 11g (and 10.2.0.4 with backport and event [1] ) you can use dbms_shared_pool.purge to purge single sql statements. Maybe that helps? Another method I would try is to handle the cursor of your execute immediate explicite and close it asap afterwards.
But as I have to confess I does not know what really causes the ORA-4031, these are all pure suggestions. 
Can you check what fills up your SGA?

best regards,
 Martin

Hi all
I have some problem with some dynamic sql generated by a package, it is causing ORA-4031 and I have to reboot the instance to get rid of the problem. 

The code does something like

for i in (... cursor ...)
loop
select formula
into vFormula
from calculators
where .......
execute immediate 'BEGIN :EXITCODE:='||vFormula||'; END;';
end loop;

vFormula contains mathematical formulas
The cursor returns around 30000 rows and this is hammering the shared pool 30000 times!
I dont see how can I avoid this dynamic SQL without doing some major changes (how the formulas are stored for example) and wonder if anyone have some idea. 


TIA


Alex
