Hi.

Execute in sqltrace is for that particular session only whereas in statspack, it's system wide.
A lot of sessions might have executed the same query.

Best regards

        Subject:        Trace versus Statspack data

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

Following SQL Query Shows DIFFERING values 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
