Max number of records to hold in explicit cursor

Question

Hi Everyone,
What is the maxmimum number of records that could be holded in
an explicit cursor for manipulation. I need to process millions of records.
Can I hold it in cursors or use temp table to hold those records and
do fixes with volume control.
Thanks

Hi Kishore sorry for the delayed response,
Table1
prim_oid     sec_oid          rel_oid
pp101     cp102          101
pp101     cp103          101
pp102     cp104          101
pp102     cp105          101
Table2
ID     p_oid     b_oid     rel_oid
1     pp101     -51     102
2     pp102     -51     102
3     cp102     52     102
4     cp103     53     102
5     cp104     54     102
6     cp105     54     102
From table1 I get the parent and child recs based on rel_oid=101,
the prim_oid and sec_oid are related to another col in table2 again
with a rel_oid. I need to get all the prim_oid that are linked to -ive b_oid
in table2 whose child sec_oid are linked with +ive b_oid.
In the above case, parent pp101 linked to 2 child cp102 & cp103 and
pp102 linked to 2 child cp104 & cp105. Both pp101 and pp102 are linked
to -ive b_oid (table2), but the children of these parents are linked to +ive b_oids.
But pp101's children are linked to 2 diff b_oid and pp102's childrend are linked
to same b_oid. For my requirement I can only update b_oid of pp102 with that
of its children b_oid whereas cannot update pp101's b_oid as it children are
linked to diff b_oid's.
I've a sql that will return prim_oid, b_oid, sec_oid, b_oid as a record as below
1     pp101     -51     3     cp102     52
1     pp101     -51     4     cp103     53
2     pp102     -51     5     cp104     54
2     pp102     -51     6     cp105     54
with a cursor sql that returns records as above, it would be difficult to process
distinct parent and distinct child. So I've a cursor that returns only the parent
records as below,
1     pp101     -51
2     pp102     -51
and then for each parent I get the distinct child b_oid, if I get only one child
b_oid I update parent else dont. but the problem is table2 has 8 million parent recs
with link to -ve b_oid but child of only 2 million recs have link to only one distinct
b_oid.
If i include volume control in the cursor sql chances are all might returns like
pp101 for which update is not required, so I should not have volume control in
curosr sql which will now return all the 8 million record. (my assumption).
is there any other feasible solution? Thanks
