You either have a SQL problem and this is the incorrect place to ask.

How to know query execution time in sql plus

HI
I want to know the query execution time in sql plus along with statistics
I say set time on ;
set autotrace on ;
select * from view where usr_id='abcd';
if the result is 300 rows it scrolls till all the rows are retrieved and finally gives me execution time as 40 seconds or 1 minute.. (this is after all the records are scrolled )
but when i execute it in toad it gives 350 milli seconds..
i want to see the execution time in sql how to do this
database server 11g and client is 10g
regards
raj

what is the difference between .. the
statistics gathered in sql plus something like this and the one that i get from plan_table in toad?
how to format the execution plan I got in sqlplus in a proper understanding way?

Exact time of SQL query execution.

Hi,
Is there any way to get the exact time of execution of particular SQL query.
Oracle Version : 10.2.0.4.0
OS : Sun OS.
Thx,
Gowin.

In general it's pretty hard.
Look at V$SQLSTAT.ELAPSED_TIME and DBA_HIST_SQLSTAT.ELAPSED_TIME_TOTAL/DELTA (need a license).
It will give you accurate results for a non-parallel query. For parallel queries you'll get a total time spent by all slaves.
Also you can enable tracing either on database or session level and analyze the trace files generated.

Need a Query to Get Execution time of each query in Proc if its running

I am looking for query which give total execution time of individual query running currently ?
we have queries but it will give cumulative time from the start date,
for example - if stored proc has 10 queries , if each query taking 10 seconds it should show me 10 secoond if its running, not from when stored proc execution started , if you have any query please let me know
only for running queries ,

Is this the logic you're after?
DECLARE @timeStamp DATETIME2 = CURRENT_TIMESTAMP, @lapTimeStamp DATETIME2, @x INT = 0
SET @lapTimeStamp = CURRENT_TIMESTAMP
WHILE @x < 10000
BEGIN
SET @x = @x + 1
END
PRINT CAST(DATEDIFF(MS,@TIMESTAMP,CURRENT_TIMESTAMP) AS VARCHAR) + ' milliseconds have elapsed since the begining of the proc. ' + CAST(DATEDIFF(MS,@lapTimeStamp,CURRENT_TIMESTAMP) AS VARCHAR) + ' have elapsed since the last batch'
SET @lapTimeStamp = CURRENT_TIMESTAMP
SET @x = 0
WHILE @x < 10000
BEGIN
SET @x = @x + 1
END
PRINT CAST(DATEDIFF(MS,@TIMESTAMP,CURRENT_TIMESTAMP) AS VARCHAR) + ' milliseconds have elapsed since the begining of the proc. ' + CAST(DATEDIFF(MS,@lapTimeStamp,CURRENT_TIMESTAMP) AS VARCHAR) + ' have elapsed since the last batch'
SET @lapTimeStamp = CURRENT_TIMESTAMP
SET @x = 0
WHILE @x < 10000
BEGIN
SET @x = @x + 1
END
PRINT CAST(DATEDIFF(MS,@TIMESTAMP,CURRENT_TIMESTAMP) AS VARCHAR) + ' milliseconds have elapsed since the begining of the proc. ' + CAST(DATEDIFF(MS,@lapTimeStamp,CURRENT_TIMESTAMP) AS VARCHAR) + ' have elapsed since the last batch'

How to find the execution time of a query?

hi guys,
i need to find the execution time of a query.
i tried finding it in rsrt but couldn find the execution time.
pleasse let me know the way to do it..
regards
sagar

Hi sagar,
If you want to know the frontend time, first of all you need to maitain the BW Statistics. To maintain you have to go the respective target and click on it. Go to the tools, select BW Statistics of infoprovider. It pop ups a window there you find two check boxes 1) WHM and 2) Front end time. Check both.
Now Exe query and close the analyzer. Then go to SE11 table RSDDSTAT. There is one field which displays Frentend time.
OR
Go to STO3 here also you can analys the frontend time.
If you feel useful Assign Pts.

Execution time of a query

Hi,
I am trying to find the execution time of a SQL query.
How to do it?
Regards.
Ashish

>I am trying to find the execution time of a SQL query.
How to do it?
Psuedo code:
time = SystemTime() -- get the current system time
RunSQL() -- run the SQL statement
print( SystemTime()-time ) -- displays the difference in time
Needless to say that this is utterly useless most of the time. The first time a query is run it may be subjected to a hard parse. The second time not. So the exact same SQL will show different execution times. This execution time measurement is useless as it does not tell you anything - except that there was a difference in time.
The first time a query runs it make do a lot of physical I/O to read the data from disk. The second time around, with the data in the db buffer cache, it makes use of logical I/O. There is a significant difference in the execution of the exact same SQL. Again, the measurement of execution is meaningless. It does not tell you anything. One number versus another number. Nothing meaningful to compare.
Fact. The very same SQL will have different execution times.
So what do you hope to gain from measuring it?

Current execution time of sql

Hi Folk
Have Oracle 9i2.
How can i find out the current execution time of a running or an ended sql/query? is there any view like v$session_longops? i will see the query and the time of the query.
Regards

Maybe this example can give you some ideas
Example 1:
SQL> declare
2 start_time timestamp;
3 end_time timestamp;
4 i number;
5 begin
6 select current_timestamp into start_time
7 from dual;
8 select count(1) into i
9 from all_objects;
10 select current_timestamp into end_time
11 from dual;
12 dbms_output.put_line('Query Run Time : '||to_char(end_time-start_time,'HH:MM:SSXFF')||'');
13* end;
SQL> /
Query Run Time : +000000 00:00:01.795964000
PL/SQL procedure successfully completed.
SQL> set timing on
SQL> select count(1)

How to get the execution time of a query

Hi,
Environment: 10.2.0.4.0
Just wondering how I can get the query execution time? I am not interested in the query output nor do I want the statistics, just the execution time?
Any suggestions will be appreciated
Thanks in advance

If you're using SQL*Plus
SQL> set autotrace traceonly
SQL> set timing on
SQL> <<your query here>>SQL*Plus will fetch all the data and then report the query plan, execution statistics, and elapsed time. It will not display the actual data.
SET TIMING ON alone tells SQL*Plus to display the execution time of each SQL statement-- the problem is that it also displays all the data which can skew the results because you're including the time required by SQL*Plus to pipe a bunch of data to the screen.

Feature request - execution time in SQL Developer

I am looking for some feature to detail the execution time of packages/stored procedures/functions. When a package completes execution, lets say, it took longer time than usual ; I would like to know which stored procedures or SQLs within took the longest time. I could trace the session. It will be very helpful if there is a feature on the tool.
Thanks

Look into PL/SQL Profiling. If you are on RDBMS version 11, then profiling command appears in context menu and toolbar.

Query Execution Time for a Query causing ORA-1555

dear Gurus
I have ORA-01555 error , earlier I used the Query Duration mentioned in Alert Log and increased the Undo Retention as I did not find th UnDOBLKS column of v$undostat high for the time of occurence of ORA-01555..
But new ORA-01555 is coming whose query duration exceeds Undo Retention time..
My question -
1. Is it possible to accurately find the query duration time besides the Alert Log file ?

abhishek, as you are using an undo tablespace and have already increased the time that undo data is retained via undo_retention then you might want to consider the following ideas which were useful with 1555 error under manual rbs segment management.
1- Tune the query. The faster a query runs the less likely a 1555 will occur.
2- Look at the processing. If a process was reading and updating the same table while committing frequenctly then the process under manual rbs management would basically create its own 1555 error rather than just being the victum of another process changing data and the rbs data being overlaid while the long running query was still running. With undo management the process could be generating more data than can be held for the undo_retention period but because it is committed Oracle has been told it doesn't really have to keep the data for use rolling back a current transaction so it gets discarded to make room for new changes.
If you find item 2 is true then separating the select from the update will likely eliminate the 1555. You do this by building a driving table that has the keys of the rows to be updated or deleted. Then you use the driver to control accessing the target table.
3- If the cause of the 1555 is or may be delayed block cleanout then select * from the target prior to running the long running query.
Realistically you might need to increase the size of the undo tablespace to hold all the change data and the value of the undo_retention parameter to be longer than the job run time. Which brings up back to option 1. Tune every query in the process so that the job run time is reduced to optimal.

dear mark
Thanks for the excellent advise..I found that the error is coming because of frequent commits..which is item 2 as u righly mentioned ..
I think I need to keep a watch on the queries running , I was just trying to find the execution time for the queries..If there is any way to find the query duration without running a trace ..
