We are doing Interest processing on a SET of 10,000 Bank A/cs

SQL Query :-

select <field names>,rowid into :b0,:b1,... from TBA_ENTITY_INTEREST_TBL
where (entity_id=:b105 and entity_type=:b106) for update of <same (above) field names> nowait;  

Above SQL Query Shows DIFFERING values (taken concurrently) for:- "Execute" from SQL_TRACE = 2584
"Executions" from Statspack report = 10,000  

Qs. What is the reason for this?  

SQL_TRACE :-   call count cpu elapsed disk query current rows
------- ------ -------- ---------- ---------- ---------- ----------

---

Parse 1 0.00 0.00 0 0 0 0
Execute 2584 0.55 0.55 0 10475 2783 0
Fetch 2584 0.50 0.51 0 0 0 2584
------- ------ -------- ---------- ---------- ---------- ----------

---

total 5169 1.05 1.06 0 10475 2783 2584    

Statspack :-

                                                     CPU      Elapsd

select TO_CHAR(accrued_upto_date_cr,'DD-MM-YYYY HH24:MI:SS') ,TO

_CHAR(accrued_upto_date_dr,'DD-MM-YYYY HH24:MI:SS') ,TO_CHAR(las
t_accrual_run_date_cr,'DD-MM-YYYY HH24:MI:SS') ,TO_CHAR(last_acc
rual_run_date_dr,'DD-MM-YYYY HH24:MI:SS') ,TO_CHAR(booked_upto_d

ate_cr,'DD-MM-YYYY HH24:MI:SS') ,TO_CHAR(booked_upto_date_dr,'DD  

NOTE - Actual SQL Query partly visible above too in statspack Output

Will provide any data needed

Thanks
