avoid dynamic SQL

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
