i wrote two queries first one was a static query which looked somthin like this
select sum(qnty)
from table_name
where...
the same query i wrote using EXEC IIMMEDIATE like
stmt:='SELECT*........'
execute immediate stmt into sum using x
somthin like above
now i found that the exec immediate ran a lot more faster than the static query, although it wasnt used in any loop. can somone tell me why performance was enhanced in exec immediate again someone tell me the diff between EXEC immediate and dbms_sql..which is better
