RE: avoid dynamic SQL

Alex,
 
    What is your current shared pool size?  Also, is it possible for
your developer to close/rollback his efforts so that the space can be
reclaimed.  Say:
 
for i in (... cursor ...)
loop
select formula
into vFormula 
from calculators
where .......
execute immediate 'BEGIN :EXITCODE:='||vFormula||'; Rollback; END;';
end loop;

Subject: avoid dynamic SQL


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
