Number of rows fetch are not same

Question

Hello all,
i am new to sql/plsql
Oracle version 11R2
OS RHL 5.0
i am trying to delete all the rows from parent table as well as from child tables based on some date criteria.
the parent table BE_STATUS contains one column OOC_DT. based on the OOC_DT i am fetching rows from Parent Table BE_STATUS.
other child tables DO NOT have OOCDT column but are having BENO and BEDT WHICH are also in PARENT TABLE BESTATUS.
So i am fetching all be_no,*be_dt* from BE_STATUS based on the column OOC_DT as below
select distinct(count(*)) from be_status where ooc_dt between '31-mar-10' AND '24-dec-10';
(COUNT(*))
65074 and i am creating a temp table based on the above query as
create table temp as select be_no, be_dt from be_status where ooc_dt between '31-mar-10' AND '24-dec-10';
table created.and then i am counting the number of rows in temp table
select distinct(count(*)) from temp;
(COUNT(*))
65074 so there are around 51 child tables which are having the column BE_NO AND BE_DT.
so the total no of rows in temp should be equal to total of all rows in each and every column based on the criteria above.
that is
select distinct(count(*)) from be_penal  where (be_no,be_dt) in (select be_no,be_dt from temp);
(COUNT(*))
        64
select distinct(count(*)) from be_fine  where (be_no,be_dt) in (select be_no,be_dt from temp);
(COUNT(*))
        62
select distinct(count(*)) from be_cash_lic  where (be_no,be_dt) in (select be_no,be_dt from temp);
(COUNT(*))
        23
select distinct(count(*)) from c_cl_be  where (be_no,be_dt) in (select be_no,be_dt from temp);
(COUNT(*))
         2
select distinct(count(*)) from chex where (be_no,be_dt) in (select be_no,be_dt from temp);
(COUNT(*))
         0
select distinct(count(*)) from amend_q where (be_no,be_dt) in (select be_no,be_dt from temp);
(COUNT(*))
         0
select distinct(count(*)) from be_perm  where (be_no,be_dt) in (select be_no,be_dt from temp);
(COUNT(*))
       889
select distinct(count(*)) from exam_instr where (be_no,be_dt) in (select be_no,be_dt from temp);
(COUNT(*))
       690
select distinct(count(*)) from c_rms_mesg  where (be_no,be_dt) in (select be_no,be_dt from temp);
(COUNT(*))
     64982
select distinct(count(*)) from item_duty_fg  where (be_no,be_dt) in (select be_no,be_dt from temp);
(COUNT(*))
    398129
select distinct(count(*)) from a_item_det  where (be_no,be_dt) in (select be_no,be_dt from temp);
(COUNT(*))
     31453
select distinct(count(*)) from item_det  where (be_no,be_dt) in (select be_no,be_dt FROM temp);
(COUNT(*))
    622271 so as u can see that TEMP TABLE contains only *65074* . so the sum of the counts of all the above tables should be *65074* but alone item_det contains
*622271* rows.
am i making any mistake in counting the records individually??
waiting for your usefull reply
thanks and regards

Not quite sure I follow your issue, but one glaringly obvious fault in your coding...
between '31-mar-10' AND '24-dec-10';dates should be treated as dates, not strings, and we left 2 digit years from programming standards waaay back in the 1990's when everyone fixed such issues as part of the millenium bug fixes.
between to_date('31-mar-2010','DD-MON-YYYY') AND to_date('24-dec-2010','DD-MON-YYYY');
