Optimize a query
i have query which is taking too much time(54 min) .the main reason of getting slow is that table is too huge.
INSERT INTO Table1 (Col1,Col2,Col3,Col4,Col5,Col6)
(SELECT DISTINCT "Col1","Col2","Col3","Col4","Col5","Col6"
FROM Table2
WHERE "Col6">0 AND "Col1"<9999 AND "paraDate">
(SELECT collDate FROM Table3 WHERE "Col1"=Col1))
UNION
(SELECT DISTINCT "Col1","Col2","Col3","Col4","Col5","Col6"
FROM Table10
WHERE "Col6">0 AND "Col1"<9999 AND "paraDate">
(SELECT colDate FROM Table3 WHERE "Col1"=Col1))
UNION
(SELECT "Col1","Col2","Col3","Col4","Col5","Col6"
FROM Table4
WHERE "Col6">0 AND "Col1"<9999
MINUS
SELECT Col1,Col2,Col3,Col4,Col5,Col6
FROM Table5)
UNION
(SELECT "Col1","Col2","Col3","Col4","Col5","Col6"
FROM Table6
WHERE "Col6">0 AND "Col1"<9999
MINUS
SELECT Col1,Col2,Col3,Col4,Col5,Col6
FROM Table7)
UNION
(SELECT a."Col1",a."Col2",a."Col3",a."Col4",a."Col5",a."Col6"
FROM Table8 a, Table9 b
WHERE a."Col6">0 AND a."Col1"<9999
AND a."Col1"=b.Col1
AND a."Col2"=b.Col2
AND a."Col3"=b.Col3
AND a."Col4"=b.Col4
AND a."Col5"=b.Col5
AND a."Col6"=b.Col6)
i want to optimize it.
Hi,
Firstly, I would say/ask, can you use "UNION ALL" instead of "UNION". Basically you are taking union of 5-6 queries which will try to take only unique values. It is a costly operation. If you do not expect to get same values of col1, col2.....col6 from Table2,10,4,5,6,7,8,9, then use UNION ALL, it will save some good time. In short, understand the difference between UNION and UNION ALL and apply it here, if possible.
I guess, you have changed the original/actual table and column names before posting the query on the forum for anonymity, which is fair enough. But as we have no idea about the indexes on various tables, it is very difficult to comment.

Help needed to optimize the query
Help needed to optimize the query:
The requirement is to select the record with max eff_date from HIST_TBL and that max eff_date should be > = '01-Jan-2007'.
This is having high cost and taking around 15mins to execute.
Can anyone help to fine-tune this??
SELECT c.H_SEC,
c.S_PAID,
c.H_PAID,
table_c.EFF_DATE
FROM MTCH_TBL c
LEFT OUTER JOIN
(SELECT b.SEC_ALIAS,
b.EFF_DATE,
b.INSTANCE
FROM HIST_TBL b
WHERE b.EFF_DATE =
(SELECT MAX (b2.EFF_DATE)
FROM HIST_TBL b2
WHERE b.SEC_ALIAS = b2.SEC_ALIAS
AND b.INSTANCE =
b2.INSTANCE
AND b2.EFF_DATE >= '01-Jan-2007')
OR b.EFF_DATE IS NULL) table_c
ON table_c.SEC_ALIAS=c.H_SEC
AND table_c.INSTANCE = 100;To start with, I would avoid scanning HIST_TBL twice.
Try this
select c.h_sec
, c.s_paid
, c.h_paid
, table_c.eff_date
from mtch_tbl c
left
join (
select sec_alias

or eff_date is null
where eff_date = max_eff_date
or eff_date is null
) table_c
on table_c.sec_alias = c.h_sec

Hi,
This below query is taking more than 1hour. So I want to optimize this query.Any suggestion is appriciated.
In Table customer_details total number of records are 40,000. Among which custno with id='J' are 7000.

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

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. -
How does XDB optimize XML Query?
I found the query speed of XDB is much slower than Berkeley XML DB.
How does XDB optimize XML Query?
Are there any documents on this subject?
And can XDB create indices on XMLType ( e.g. the index on element/attribute value and/or structure index)? if yes, how to do that?lezhou had a valid question and asked about:
"I found the query speed of XDB is much slower than Berkeley XML DB"
"How does XDB optimize XML Query?"
These point to a "XML DB Concepts Guide", which does not yet exist.
The procedures are explained, the methods are explained. If you enable event tracing as described in the XMLDB Developers Guide 10gR2, you will see statements in your trace file which will tell you more about the XML DB architecture (and therefor you can deduct performance impact) then the manual will reveal.
An other example:
The xdbconfig.xsd file is neatly explained - in regards of http-port-etc
But not what the implecations are if you alter one of the other ones (the not explained parameters).
If you know the architecture (GROUND LEVEL), you can give an correct answer to the initial question "I found the query speed of XDB is much slower than Berkeley XML DB. How does XDB optimize XML Query?"
The balanced tree index is constructed the same way (on the same theory) in Oracle, DB2, but apparantly X is faster because in with the same buildup/architecture/databasestructure for both products, with the same data, with the same X --> value Y is beter constructed and delivers a better performance.
apples = apples
oracle xmldb = berkeley xmldb --> how can i test the o.apples=b.apples and that under these circumstances o.apples are faster ;-)
THEREFOR:
"I have to disagree a little bit...("It speaks about all these in detail").
Still waiting for the XMLDB Concepts Guide / Administrators Guide / Performance Guide. -
Hi..
The below select query is causing performance issue in production , it is taking much time.
Please suggest how to optimize it .

Edited by: Rob Burbank on Oct 13, 2009 10:49 AMHi Chetan,
I suggest the following to optimize your performance.
- Change the order of the fields (belnr bukrs gjahr awkey blart), so that they're in the same order than showned in SE11 table data definition (you may need to change the order in t_bkpf definiton also).
- Add the client in your select statement.
Something like this:
SELECT bukrs belnr gjahr blart awkey FROM bkpf CLIENT SPECIFIED
INTO TABLE t_bkpf
WHERE mandt = sy-mandt
AND bukrs IN s_bukrs
AND gjahr IN r_year.
Your statement it's very simple. I don't think that there is much more to do.
Hope that helps.
Kind regards.

Hi !!!
Please anybody can help me ?
I have this Stand Alone Procedure:
==========>
declare cursor c1 is
select
A.UNIT,
A.CODE,
A.PREFIX,
A.PART,
A.TYPE_CODE,
B.VALUE
FROM
TABLEA A,
TABLEB B
WHERE
A.UNIT||A.CODE||A.PREFIX||A.PART||A.TYPE_CODE =
B.UNIT||B.CODE||B.PREFIX||B.PART||B.TYPE_CODE
AND A.VALUE != B.VALUE;
VARUNIT TABLEA.UNIT%TYPE;
VARPREFIX TABLEA.PREFIX%TYPE;
VARPART TABLEA.PART%TYPE;
VARTYPE_CODE TABLEA.TYPE_COD%TYPE;
VARVALUE TABLEB.VALUE%TYPE;
BEGIN
OPEN C1;
LOOP;
FETCH C1 INTO VARUNIT,VARPREFIX,VARPART,VARTYPE_CODE,VARVALUE;
EXIT WHEN C1%NOTFOUND;
UPDATE TABLEA
SET VALUE = VARVALUE
WHERE
TABLEA.UNIT||TABLEA.CODE||TABLEA.PREFIX||TABLEA.PART||TABLEA.TYPE_CODE =
VARUNIT||VARCODE||VARPREFIX||VARPART||VARTYPE_CODE;
COMMIT;
END LOOP;
END;
<===============
In tableA i have - 170.000 records and in tableB i have - 30.000.
I need to optimize this procedure, anybody has any idea How i can optimize it ?
Thanks in advanced.
Gerson Belini.Sure,
1) Either make a indexed function
CREATE INDEX TABLEA_N01 ON TABLEA ( Unit || Code || Prefix || Part || Type_Code );
or
2) Make a regular index, and change your query to the below
CREATE INDEX TABLEA_N01 ON TABLEA ( Unit, Code, Prefix, Part, Type_Code );
Even creating an index on some of the fields would most likely help
SELECT A.Unit
, A.Code
, A.Prefix
, A.Part
, A.Type_Code
, B.Value
FROM
TABLEA A
, TABLEB B
WHERE A.Unit = B.Unit
AND A.Code = B.Code
AND A.Prefix = B.Prefix
AND A.Part = B.Part
AND A.Type_Code = B.Type_Code
AND A.Value != B.Value;Good Luck,

How should I optimize this query
Hi
I have following query
SELECT /*+ USE_HASH (bp,rp) */ TO_CHAR (part_name)
FROM base_part bp,risk_assessment_part rp
WHERE bp.part_number = rp.part_number and risk_activity_code = 1
Explain Plan for this is
SELECT STATEMENT Optimizer Mode=CHOOSE
NESTED LOOPS
TABLE ACCESS FULL GQTS6USER.BASE_PART ROWS 4M , BYTES 331M, COST 7731
INDEX UNIQUE SCAN GQTS6USER.XPK_RISK_ASSESSMENT_PART ROWS 1, BYTES 22
Is there any way to optimize qry execution time???Make sure you have indexes on the columns used in join and filter conditions. Gather current statistics. Remove the TO_CHAR. Test the query with and without the hint and compare times and execution plans. Bear in mind the optimizer may choose to ignore a hint if it determines that there is a better plan.

How can I optimize this select query? Basically, how can I factor out the common codes in the query below
(i.e. r.batch_id is null AND r.rpt_type='Child' is a common criteria for the two filter conditions)
SQL:
SELECT DISTINCT rpt_id, rpt_name, emp_id
FROM REPORT r
WHERE r.batch_id is null
AND r.rpt_type='Child'
--filter by BU only
AND (r.BU IN (SELECT BU FROM BUnit WHERE Active='Y'))
--filter by BU/OU combination
OR r.batch_id is null
AND r.rpt_type='Child'
AND (r.BU || ' ' || R.OU IN (SELECT BU || ' ' || OU FROM BUnit WHERE Active='Y'))
Thank you.

How can I optimize this select query? query is already optimized.
