How to performance tune this query
I need some inputs on how to do performance tuning on this query to improve performance.
It takes around 45 secs to run. Is it possible to make any improvements in this by putting hints or writing in another way?
select count(*)
as nCount from A ,
B ,
C
WHERE A.COL1 = B.COL1 AND
A.COl2 <> 'COM' AND
B.COL2 = C.COL1 AND
B.COl3 IS NULL AND
B.COL4 = 'TEST'
This is the query plan:
Operation Object Name Rows Bytes Cost Object Node In/Out PStart PStop
SELECT STATEMENT Optimizer Mode=CHOOSE 1 51
SORT AGGREGATE 1 37
HASH JOIN 48 K 1 M 51
TABLE ACCESS FULL A 68 K 998 K 32
NESTED LOOPS 98 K 2 M 5
TABLE ACCESS BY INDEX ROWID B 142 K 2 M 4
INDEX SKIP SCAN XIF37B 142 K 6
INDEX UNIQUE SCAN XPKC 1 5
Mcka
As well as EXPLAIN PLAN, let us know what proportion of rows are visited by this query. It may be that it is not using a full table scan when it should (or vice versa).
And of course we'd need to know what indexes are available, and how selective they are for the predicated you have in this query ...

Removed the post because of a major logical flaw. Thanks to Boneist for his great idea.
Edited by: user10633418 on Nov 20, 2008 3:21 AMI think I would try rewriting the query to turn the exists clauses into full joins, like:
SELECT mph.MANIF_NBR AS A1,
mph.SHPR_ID AS A5,
mph.MANIF_TYPE AS A4,
mph.LOAD_NBR AS A21,
mph.STAT_CODE AS A7,
mph.CLOSE_DATE AS A10,
mph.SHIP_DATE_TIME AS A24,
mph.UPS_PIKUP_NBR AS A9,
mph.WHSE AS A2,
mph.PIKUP_REC_NBR AS A8,
manh_carr_type_for_manif_nbr(mph.WHSE,mpc.MANIF_NBR) AS A26,
mph.UPS_PLD_UPLOAD_INDIC AS A28,
'PARCELMANIF_CD' AS A29
FROM MANIF_PARCL_HDR mph,
MANIF_PARCL_CARTON mpc,
PARCL_SHPMT ps
WHERE mph.MANIF_NBR = mpc.MANIF_NBR
AND mph.MANIF_NBR = ps.MANIF_NBR
AND mph.WHSE = 'HAN'
AND ps.CD_MASTER_ID IN (1001)
ORDER BY MANIF_PARCL_HDR.MANIF_NBR ASC,
MANIF_PARCL_HDR.MANIF_TYPE ASCand then compare how fast that runs and what the explain plan is, etc. -
How to tune this query for the improve performance ?
Hi All,
How to tune this query for the improve performance ?
select a.claim_number,a.pay_cd,a.claim_occurrence_number,
case
when sum(case

then 0
else (sum(case
when a.payment_status_cd='0'and a.payment_est_amt > 0
then a.payment_est_amt
else 0
end)
- sum(case
when a.payment_status_cd<>'0'
then a.payment_amt
else 0
end))
end as estimate
from ins_claim_payment a
where a.as_of_date between '31-jan-03' and '30-aug-06'
and ( a.data_source = '25' or (a.data_source between '27' and '29'))
and substr(a.pay_cd,1,1) IN ('2','3','4','8','9')

Please help me how to improve the performance of this query further.
Hi All,
Please help me how to improve the performance of this query further.
Thanks.Hi,
this is not your first SQL tuning request in this community -- you really should learn how to obtain performance diagnostics.
The information you posted is not nearly enough to even start troubleshooting the query -- you haven't specified elapsed time, I/O, or the actual number of rows the query returns.
The only piece of information we have is saying that your query executes within a second. If we believe this, then your query doesn't need tuning. If we don't, then we throw it away
and we're left with nothing.
Start by reading this blog post: Kyle Hailey &raquo; Power of DISPLAY_CURSOR
and applying this knowledge to your case.

Thanks in advance.Hi,
Thanks for your reply.
For split the numbers into different rows , we are sending randomly.
It's not constant numbers.We have used bind variables.
For testing purpose I have hard coded the values.
How to do this split without using user defined function.
I am sending the actual query along with execution plan without any hints.

Is there anyway i could tune this query?
note: Ignore the unnecessary brackets. They are system created(apparently by hibernate)

NicholsFrom just blindly looking at this particular query, there doesn't seem any obvious reason why an index couldn't be extended to cover all the columns specified in the where clause.
It might not help too much -> explain plan is required first really before blindly guessing.
Obviously, there's no point having an order by and a rownum (unless you wanted to do the order by before the rownum in an outer select) - I assume this is just a Hibernatism. -

PLEASE IF YOU FIND SOMETHING WRONG.. PLEASE HELP ME.. this query takes me aproximatelly 10 minutes and the database is really small ( with only 200 records on each table )You are querying eight tables, however in any of your OR predicates you're only restricting 3 or 4 of those tables. That means that the remaining 4 or 5 tables are generating cartesian products. (n.b. the cartesian product of 5 tables with 200 rows each results in g 200^5 = 320,000,000,000 rows) Then you casually hide this behind "distinct".
A simple restatement of your requirements looks like this:
Select eopersona.numident
From rscompeten,
rscompet,
rscv,
eopersona
Where LOWER (rscompeten.nombre) LIKE '%caracas%'
AND rscompeten.id = rscompet.idcompeten
AND rscv.id = rscompet.idcv
AND eopersona.id = rscv.idpersona
UNION
Select eopersona.numident
From rscurso ,
rscv,
eopersona
Where LOWER (rscurso.nombre) LIKE '%caracas%'
AND rscv.id = rscurso.idcv
AND eopersona.id = rscv.idpersona
UNION
Select eopersona.numident
From rscurso ,
rscv,
eopersona
Where LOWER (rscurso.lugar) LIKE '%caracas%'
AND rscv.id = rscurso.idcv
AND eopersona.id = rscv.idpersona
UNION
...From there you can eliminate redundancies as desired, but I imagine that the above will perform admirably with the data volumes you describe. -

7 - filter(TO_NUMBER("C"."RESTART_FLAG")=0) It means that Oracle had to do a conversion for you since you aren't using the proper data type in your query.
That would mean IF there is an index on that column, it won't be useable... -
Sql Query Tuning. Please help me to tune this query
Hi All ,
I have this problematic Sql . It is taking huge time to execute. It contains a view CIDV, which i think is the bottleneck.
I have pasted the query below. I will be pasting TKPROF and explain plan for the same. Please advice me to tune this query.

How I can change this query, so I can display the name and scores in one r
How I can change this query, so I can add the ID from the table SPRIDEN

Hi,
That depends on whether spriden_pidm is unique, and on what you want for results.
Whenever you have a problem, post a little sample data (CREATE TABLE and INSERT statements, relevamnt columns only) for all tables, and the results you want from that data.
If you can illustrate your problem using commonly available tables (such as those in the scott or hr schemas) then you don't have to post any sample data; just post the results you want.
Either way, explain how you get those results from that data.
Always say which version of Oracle you're using.
It looks like you're doing something similiar to the following.
Using the emp and dept tables in the scott schema, produce one row of output per department showing the highest salary in each job, for a given set of jobs:
DEPTNO DNAME LOC JOB_1 SAL_1 JOB_2 SAL_2 JOB_3 SAL_3
20 RESEARCH DALLAS ANALYST 3000 MANAGER 2975 CLERK 1100
10 ACCOUNTING NEW YORK MANAGER 2450 CLERK 1300
30 SALES CHICAGO MANAGER 2850 CLERK 950On each row, the jobs are listed in order by the highest salary.
This seems to be analagous to what you're doing. The roles played by sortest_pidm, sortest_tesc_code and sortest_test_score in your sortest table are played by deptno, job and sal in the emp table. The roles played by spriden_pidm, id and name in your spriden table are played by deptno, dname and loc in the dept table.
It sounds like you already have something like the query below, that produces the correct output, except that it does not include the dname and loc columns from the dept table.
SELECT deptno
, MAX (DECODE (rn, 1, job)) AS job_1
, MAX (DECODE (rn, 1, max_sal)) AS sal_1
, MAX (DECODE (rn, 2, job)) AS job_2
, MAX (DECODE (rn, 2, max_sal)) AS sal_2
, MAX (DECODE (rn, 3, job)) AS job_3
, MAX (DECODE (rn, 3, max_sal)) AS sal_3
FROM (
SELECT deptno
, job
, max_sal
, ROW_NUMBER () OVER ( PARTITION BY deptno
ORDER BY max_sal DESC
) AS rn
FROM (
SELECT e.deptno
, e.job
, MAX (e.sal) AS max_sal
FROM scott.emp e
, scott.dept d
WHERE e.deptno = d.deptno
AND e.job IN ('ANALYST', 'CLERK', 'MANAGER')
GROUP BY e.deptno
, e.job
GROUP BY deptno
;Since dept.deptno is unique, there will only be one dname and one loc for each deptno, so we can change the query by replacing "deptno" with "deptno, dname, loc" throughout the query (except in the join condition, of course):
SELECT deptno, dname, loc -- Changed
, MAX (DECODE (rn, 1, job)) AS job_1
, MAX (DECODE (rn, 1, max_sal)) AS sal_1
, MAX (DECODE (rn, 2, job)) AS job_2
, MAX (DECODE (rn, 2, max_sal)) AS sal_2
, MAX (DECODE (rn, 3, job)) AS job_3
, MAX (DECODE (rn, 3, max_sal)) AS sal_3
FROM (
SELECT deptno, dname, loc -- Changed
, job
, max_sal
, ROW_NUMBER () OVER ( PARTITION BY deptno -- , dname, loc -- Changed
ORDER BY max_sal DESC
) AS rn
FROM (
SELECT e.deptno, d.dname, d.loc -- Changed
, e.job
, MAX (e.sal) AS max_sal
FROM scott.emp e
, scott.dept d
WHERE e.deptno = d.deptno
AND e.job IN ('ANALYST', 'CLERK', 'MANAGER')
GROUP BY e.deptno, d.dname, d.loc -- Changed
, e.job
GROUP BY deptno, dname, loc -- Changed
;Actually, you can keep using just deptno in the analytic PARTITION BY clause. It might be a little more efficient to just use deptno, like I did above, but it won't change the results if you use all 3, if there is only 1 danme and 1 loc per deptno.
By the way, you don't need so many sub-queries. You're using the inner sub-query to compute the MAX, and the outer sub-query to compute rn. Analytic functions are computed after aggregate fucntions, so you can do both in the same sub-query like this:
SELECT deptno, dname, loc
, MAX (DECODE (rn, 1, job)) AS job_1
, MAX (DECODE (rn, 1, max_sal)) AS sal_1
, MAX (DECODE (rn, 2, job)) AS job_2
, MAX (DECODE (rn, 2, max_sal)) AS sal_2
, MAX (DECODE (rn, 3, job)) AS job_3
, MAX (DECODE (rn, 3, max_sal)) AS sal_3
FROM (
SELECT e.deptno, d.dname, d.loc
, e.job
, MAX (e.sal) AS max_sal
, ROW_NUMBER () OVER ( PARTITION BY e.deptno
ORDER BY MAX (sal) DESC
) AS rn
FROM scott.emp e
, scott.dept d
WHERE e.deptno = d.deptno
AND e.job IN ('ANALYST', 'CLERK', 'MANAGER')
GROUP BY e.deptno, d.dname, d.loc
, e.job
GROUP BY deptno, dname, loc
;This will work in Oracle 8.1 and up. In Oracle 11, however, it's better to use the SELECT ... PIVOT feature. -

A conjuction (AND expression) has a higher priority and will be executed (logically) before the disjunction (OR expression)! So your select looks like this

;This might be want you want, but I doubt it very much. Please add parenthesis', to get it working the way it should be.

Hi guys i am beginner , just wanted to know some info , how can i improve this query ..
select *
from tableA A, viewB B,
where A.key = B.key
and a.criteria1 = '111'
and a.criteria2 = some_funtion(a.key)
one more thing should function should be on left side of equal sign.
will a join make it better or something else is needed more than that .952936 wrote:

will a join make it better or something else is needed more than that .If you are a beginner try to learn the ANSI Syntax. This will help you a lot to write better queries.
Your select would look like this in ANSI.
select *
from tableA A
JOIN viewB B ON A.key = B.key
WHERE a.criteria1 = '111'
and a.criteria2 = some_function(a.key);The good thing here is that this separates the typical joining part of the select from the typical filter criteria.
The other syntax very often let you forget one join. Just because there are so many tables and so many filters, that you just don't notice correctly anymore what was join and what not.
If you notice that the number of column is not what you expect, you can easiely modify the query and compare the results.
example A
Remove View B from the query (temporarily comment it out).
select *
from tableA A
--JOIN viewB B ON A.key = B.key
WHERE a.criteria1 = '111'
and a.criteria2 = some_funtion(a.key)
example B
You notice, that values from A are missing. Maybe because there is no matching key in ViewB? Then change the join to an outer join.
select *
from tableA A
LEFT OUTER JOIN viewB B ON A.key = B.key
WHERE a.criteria1 = '111'
and a.criteria2 = some_funtion(a.key)(The outer keyword is optional, left join would be enough). -
