WHERE DENSE_RANK > 2 order by myTimestamp DESC, HISTORYID, USER_ID;

and this table is created in some number of different database then i want to delete the not null constraint of "id" column and there is 3 not null constraint in my table and i didnot gave name at the time of creation, so we cant delete it by its name in the script because there will be different name in another database for the same constraint. i want to make a script to delete the not null constraint because it is the part of my script.
how should i get proper information for deleting the constraint. and i used "user_constraints" but it shows same information for the all three "not null" constraint.

I know it's not generally a good idea to delete records but in this case a large number of cases are incorrect and need to be reinserted and this is the quickest way of doing it.

Mine Delete code looks like:
if x.first is not null then
for i in x.first..x.last loop
delete tbl_A where trade_id = x(i).trade_id;
delete tbl_B where trade_id = x(i).trade_id;
[code]...
Where x is the recordset having around 10K records.Is there any way i can run the loop only once rather than one by one for 10K times.
