Oracle SQL Select query takes long time than expected.

Hi,
I am facing a problem in SQL select query statement. There is a long time taken in select query from the Database.
The query is as follows.
select /*+rule */ f1.id,f1.fdn,p1.attr_name,p1.attr_value from fdnmappingtable f1,parametertable p1 where p1.id = f1.id and ((f1.object_type ='ne_sub_type.780' )) and ( (f1.id in(select id from fdnmappingtable where fdn like '0=#1#/14=#S0058-3#/17=#S0058-3#/18=#1#/780=#5#%')))order by f1.id asc
This query is taking more than 4 seconds to get the results in a system where the DB is running for more than 1 month.
The same query is taking very few milliseconds (50-100ms) in a system where the DB is freshly installed and the data in the tables are same in both the systems.
Kindly advice what is going wrong??

Select query take long time

Hi All.
When i execute select query from View it takes about 00:00:45:12 sec to pull the data , but when i execute same query in some other system(different database with same table structure) it takes about 00:00:02:05 sec.
1)I have tried by dropped and recreated the index then i tried by exec dbms_stats.gather_table_stats procedure still no luck.
Please help me to understand the reason difference in response time
Thanks

Select query takes long time....

Hi Experts,
I am using a select query in which inspection lot is in another table and order no. is in another table. this select query taking very long time, what is the problem in this query ? Pl. guide us.

and a~aufnr in aufnr1.

hi
instead of using 'move to corresponding of itab' fields use 'into table itab'.....
coz......if u use move to corresponding it will search for all the appropriate fields then it will place u r data........instead of that declare apprpiate internal table and use 'into table itab'.
and one more thing dont use joins ......coz joins will decrease u r performance .....so instead of that use 'for all entries' ....and mention all the key fields in where condition ........

thanks in advance...That may be because your client is displaying only the first few records when you are running the "SELECT *". But when you run "COUNT(*)", the whole records has to be counted.
As already mentined please read teh FAQ to post tuning questions.

Select Query Takes more time

Hi All,
I have cloned KSB1 tcode to custom one as required by business.
Below query takes more time than excepted.
Here V_DB_TABLE = COVP.
Values in Where clause are as follows
OBNJR in ( KSBB010000001224 BT KSBB012157221571)
GJAHR in blank
VERSN in '000'
WRTTP in '04' and '11'
all others are blank
VT_VAR_COND = ( CPUDT BETWEEN '20091201' and '20091208' )
SELECT (VT_FIELDS) INTO CORRESPONDING FIELDS OF GS_COVP_EXT
                    FROM (V_DB_TABLE)
                    WHERE LEDNR = '00'
                    AND   OBJNR IN LR_OBJNR
                    AND   GJAHR IN GR_GJAHR
                    AND   VERSN IN GR_VERSN

                    AND   (VT_VAR_COND).
Checked in table for this condition it has only 92 entries.
But when i execute program takes long time as 3 Hrs.
Could any one help me on this

>1.Dont use SELECT/ENDSELECT instead use INTO TABLE addition .
> 2.Avoid using corresponding addition.create a type and reference it.
> If the select is going for dump beacause of storage limitations ,then use Cursors.
you got three large NOs .... all three recommendations are wrong!
The SE16 test is going in the right direction ... but what was filled. Nobody knows!!!!
Select options:
Did you ever try to trace the SE16? The generic statement has for every field an in-condition!
Without the information what was actually filled, nobody can say something there
are at least 2**n combinations possible!
Use ST05 for SE16 and check actual statement plus explain!

Without seeing an execution plan of the query it is hard to suggest something useful. Try insert the result of UNION ALL to the temporary table and then perform an aggregation on that table, not a CTE.
Just
SELECT CollectionDate,Bankname,DSLIPS AS DSLIPS,SUM(BN) AS BN,SUM(COINS)AS COINS FROM

SELECT statement takes long time

Hi All,
In the following code, if the T_QMIH-EQUNR contains blank or space values ,SELECT statement takes longer time to acess the data from OBJK table. If it T_QMIH-EQUNR contains values other than blank, performance is good and it fetches data very fast.
Already we have indexes for EQUNR in OBJK table.
Only for blank entries , it takes much time.Can anybody tell why it behaves for balnk entries?
if not T_QMIH[] IS INITIAL.
        SORT T_QMIH BY EQUNR.
        REFRESH T_OBJK.
        SELECT EQUNR OBKNR
          FROM OBJK INTO TABLE T_OBJK
          FOR ALL ENTRIES IN T_QMIH
          WHERE OBJK~TASER = 'SER01' AND
         OBJK~EQUNR = T_QMIH-EQUNR.
Thanks
Ajay

Hi
You can use the field QMIH-QMNUM with OBJK-IHNUM
in QMIH table, EQUNR is not primary key, it will have multiple entries
so to improve the performance use one dummy internal table for QMIH and sort it on EQUNR
delete adjacent duplicates from d_qmih and use the same in for all entries
this will improve the performance.
Also use the fields in sequence of the index and primary keys also in select
if not T_QMIH[] IS INITIAL.
SORT T_QMIH BY EQUNR.
REFRESH T_OBJK.
SELECT EQUNR OBKNR
FROM OBJK INTO TABLE T_OBJK
FOR ALL ENTRIES IN T_QMIH
WHERE IHNUM = T_QMIH-QMNUM
OBJK~TASER = 'SER01' AND
OBJK~EQUNR = T_QMIH-EQUNR.
try this and let me know

You can neglect the second query by pulling the values in first query itself
SELECT a~aufnr
       a~auart
       a~objnr
       a~werks
       b~stat
       b~inact "New Addition
              INTO CORRESPONDING FIELDS OF TABLE itab1
              FROM aufk AS A JOIN jest AS B
              ON a~objnr EQ b~objnr
              WHERE a~aufnr IN s_aufnr
              AND a~auart in s_auart
              AND A~werks IN S_IWERK.
              "AND b~inact EQ ' '. removed.
now the itab1 will consists of inact EQ ' ' and b~stat IN ('I0002','I0340').
try to process the internal table.
Dont know how far it will help you

BEx query selection screen takes long time to popup

Hi,
I have a query which is taking long time to popup the selection screen. I have tried in RSRT the generate report option, the generating report takes 45 to 60 mins. After the report is generated the query selection screen comes up in couple of seconds. The first time I run the query everything its fine but then for the second time the problem comes back again.
The selection screen takes +/- 40 mins to comes up in RSRT and in the portal it times out.
I have run the statistics of the query and according to the statistics report the query takes a lot of time for the following component :
OLAP: Query Gen. 2681,312682
I have removed the query from the cache monitor and after that regenerate the report. But these steps didnu2019t solve my problem.
I made two test queries, in one query I have made the CKFu2019s and RKFu2019s directly at the infoprovider, and dragged and dropped in the KF structure. In the other query I made the CKFu2019s and RKFu2019s in the query KF structure itself. The query where I have the CKFu2019s and RKFu2019s at the infoprovider that query times out, the other query where I put the CKFu2019s and RKFu2019s in the query KF structure doesn't has this performance problem.
What I donu2019t know is why the query is failing when I use RKFu2019s and CKFu2019s from the infoprovider, the other query donu2019t have this problem.
Please advise how to proceed.
Thanks in advance,
Arash

Hi,
Please check the following notes which should be useful.
1387593 - Performance optimization for query change/generation
1416737 - Performance optimization for query change/generation(2)
1396485 - Performance optimization for query check/save
Then please execute the SE38 report ANALYZE_RSZ_TABLES (see notes
1472915, 1506560) and repair/correct the different tables to optmize
the query definition tables.

Amit

Query takes long time for first time

I have a table with 100 million records and another tables with many rows.
When I ran a query - it's takes about 1 minute to complete, but when I ran it again it takes less than 1 second to complete.
Why it is happening?
Thanks,
Tz.

Welcome to the forum.
When you post a question always provide your 4 digit Oracle version. Different versions have different functionality and this can affect your results and the advice you need.
For performance tuning questions see the FAQ (upper right corner of page) for the information needed for tuning requests.

How did you run it? Did you use sql*plus, sqldeveloper, some other tool?
What command did you enter?
Using sql*plus you can get an execution plan for the query by
SQL> set serveroutput on
SQL> set autotrace traceonly
SQL> select * from emp;
Execution Plan
Plan hash value: 3956160932

Query takes long time on multiprovider

Hi,
When i execute a query on the multiprovider, it takes very long time. it doesnt show up the results also. It just keep processing. I have executed the report only for one day but still it doesnt show any result. But when i execute on the cube, it executes quickly and shows the result.
Actually i added one more cube to the multiprovider and ten transported that multiprovider to QA and PRD. Transportation went on successfully. After this i am unalbe to execute the reports on that multiprovider. What might be the cause? your help is appreciated.
Thanks
Annie

Hi Annie.......
Checklist for the performance of a Query........from a DOc........
1. If exclusions exist, make sure they exist in the global filter area. Try to remove exclusions by subtracting out inclusions.
2. Use Constant Selection to ignore filters in order to move more filters to the global filter area. (Use ABAPer to test and validate that this ensures better code)
3. Within structures, make sure the filter order exists with the highest level filter first.
4. Check code for all exit variables used in a report.
5. Move Time restrictions to a global filter whenever possible.
6. Within structures, use user exit variables to calculate things like QTD, YTD. This should generate better code than using overlapping restrictions to achieve the same thing. (Use ABAPer to test and validate that this ensures better code).
7. When queries are written on multiproviders, restrict to InfoProvider in global filter whenever possible. MultiProvider (MultiCube) queries require additional database table joins to read data compared to those queries against standard InfoCubes (InfoProviders), and you should therefore hardcode the infoprovider in the global filter whenever possible to eliminate this problem.
8. Move all global calculated and restricted key figures to local as to analyze any filters that can be removed and moved to the global definition in a query. Then you can change the calculated key figure and go back to utilizing the global calculated key figure if desired
9. If Alternative UOM solution is used, turn off query cache.
10. Set read mode of query based on static or dynamic. Reading data during navigation minimizes the impact on the R/3 database and application server resources because only data that the user requires will be retrieved. For queries involving large hierarchies with many nodes, it would be wise to select Read data during navigation and when expanding the hierarchy option to avoid reading data for the hierarchy nodes that are not expanded. Reserve the Read all data mode for special queriesu2014for instance, when a majority of the users need a given query to slice and dice against all dimensions, or when the data is needed for data mining. This mode places heavy demand on database and memory resources and might impact other SAP BW processes and tasks.
11. Turn off formatting and results rows to minimize Frontend time whenever possible.
12. Check for nested hierarchies. Always a bad idea.
13. If u201CDisplay as hierarchyu201D is being used, look for other options to remove it to increase performance.
14. Use Constant Selection instead of SUMCT and SUMGT within formulas.
15. Do review of order of restrictions in formulas. Do as many restrictions as you can before calculations. Try to avoid calculations before restrictions.
16. Check Sequential vs Parallel read on Multiproviders.
17. Turn off warning messages on queries.
18. Check to see if performance improves by removing text display (Use ABAPer to test and validate that this ensures better code).
19. Check to see where currency conversions are happening if they are used.
20. Check aggregation and exception aggregation on calculated key figures. Before aggregation is generally slower and should not be used unless explicitly needed.
21. Avoid Cell Editor use if at all possible.
22. Make sure queries are regenerated in production using RSRT after changes to statistics, consistency changes, or aggregates.
23. Within the free characteristics, filter on the least granular objects first and make sure those come first in the order.
24. Leverage characteristics or navigational attributes rather than hierarchies. Using a hierarchy requires reading temporary hierarchy tables and creates additional overhead compared to characteristics and navigational attributes. Therefore, characteristics or navigational attributes result in significantly better query performance than hierarchies, especially as the size of the hierarchy (e.g., the number of nodes and levels) and the complexity of the selection criteria increase.
25. If hierarchies are used, minimize the number of nodes to include in the query results. Including all nodes in the query results (even the ones that are not needed or blank) slows down the query processing. The u201Cnot assignedu201D nodes in the hierarchy should be filtered out, and you should use a variable to reduce the number of hierarchy nodes selected.
