I need to fine tune a query
Hi All,
I need to fine tune my select query . I am giving a sample query which is model of my Query .
Sample Tables: Employee, Manager, Department
Select a.employee_name,a.employee_age,decode(a.employee_status,'Y','Promoted','Still in Progress'), NVL(b.employee_details , 0),c.department_name from employee a, manager b , department c where a.employee_id =b.employee_id(+) and a.employee_id = c.employee_id(+) and c.department_status in ('Y',A') order by a.employee_joining_date
This is a sample query. In my query which should be fine tune has lot of decode and nvl functions. This query is passed to oracle as string from Java .It takes 2 seconds but it should be taking only fraction of seconds..
What shall i do?
Shall i create materialise views or a function in oracle with return value as sys_refucursor to Java code. does function based index should be used in where clause only. If so what should i do to minimise decode and nvl functions.Please help me

where a.employee_id =b.employee_id(+) and a.employee_id = c.employee_id(+) and c.department_status
in ('Y',A') order by a.employee_joining_date I'm wondering why an "employee_details" field is 0 - doesn't make much sense to me.
Also, the (+) syntax is deprecated - use standard ANSI join syntax instead (Mr. Google is your friend).
This is a sample query. In my query which should be fine tune has lot of decode and nvl functions.
This query is passed to oracle as string from Java .It takes 2 seconds but it should be taking only fraction of seconds..Why should it take only a fraction of a second? How do you know this for a fact? TKProf should be
able to tell you what's happening.

Read some performance books on Oracle - you don't mention your version of Oracle
or your OS, so it's difficult to help with that.
Christopher Lawson's book is an excellent and very readable into to Oracle performance.
Also, Oracle Performance 101 - as well as anything by Tom Kyte. More advanced stuff is
available from Jonathan Lewis and Christian Antognini. Also, take a look at the FAQ for
this group (as recommended by the other poster) and don't forget the docco*
or (short version) RTFM*.

Hi...
SELECT
a.id, a.fname, a.lname
FROM
a inner join b ON a.id = b.id
WHERE
a.del_status = 'N' AND a.type = 2
GROUP BY
a.id, a.name, a.lname
if i run this Query it take s one sec
SELECT
a.id, a.fname, a.lname
FROM
a inner join b ON a.id = b.id
WHERE
a.del_status = 'N' AND a.type = 2 and b.status =1
GROUP BY
a.id, a.name, a.lname
if i add status it takes 7 Min
i cant found the reason
this is the explain plan for second query

Thanks,Hi
If you have an index on the b.id then Oracle does not have to read the actual data in the first query.
But when you refer to status, then Oracle will have to retrieve the row and check that field.
pls. supply BOTH explain plans

I am running the following query. This is being run for every row that is being loaded. I figured that this is taking the most time
select distinct h.PRNT_PROD_GRP_ID, h.CHILD_PROD_GRP_ID, pg.PROD_GRP_REPORTING_NM, pg.PROD_GRP_ID, pg.PROD_GRP_TYP_ID
from PROD_GRP_HCHY_OUTBD h, PROD_GRP pg
where pg.PROD_GRP_ID = h.PRNT_PROD_GRP_ID and
pg.PROD_GRP_ID in (select c.PROD_GRP_ID from prod_grp p, prod_grp c, PROD_GRP_HCHY_OUTBD hy, (select h.PRNT_PROD_GRP_ID, h.CHILD_PROD_GRP_ID, level LVLID, PROD_GRP_HCHY_OUTBD_ID from PROD_GRP_HCHY_OUTBD h where h.PROD_MKT_ID in (select pga.PROD_GRP_ID from APLCTN_SYS aps, APLCTN a, PROD_GRP_APLCTN pga where aps.APLCTN_SYS_Cd = 'ETMS' AND aps.APLCTN_SYS_ID = a.APLCTN_SYS_ID and a.APLCTN_ID = pga.APLCTN_ID) start with h.PRNT_PROD_GRP_ID in (select pga.PROD_GRP_ID from APLCTN_SYS aps, APLCTN a, PROD_GRP_APLCTN pga where aps.APLCTN_SYS_Cd = 'ETMS' AND aps.APLCTN_SYS_ID = a.APLCTN_SYS_ID and a.APLCTN_ID = pga.APLCTN_ID) connect by h.PRNT_PROD_GRP_ID = prior h.CHILD_PROD_GRP_ID) TREE where p.prod_grp_id = TREE.PRNT_PROD_GRP_ID and c.prod_grp_id = TREE.CHILD_PROD_GRP_ID and hy.PROD_GRP_HCHY_OUTBD_ID = TREE.PROD_GRP_HCHY_OUTBD_ID) connect by prior h.PRNT_PROD_GRP_ID = h.CHILD_PROD_GRP_ID start with h.CHILD_PROD_GRP_ID = 7650 order by pg.PROD_GRP_TYP_ID;hey nick,
this is the query that is run by Tibco (middleware).
we are trying to extract this data from the data store and load into a target database.
this query generates a tree of parent - child rows that belong to a particular criteria.
everytime the parent is fetched for a particular child, we need to make sure that the parent falls in that criteria and hence the many (in) queries.
hope this helps -
HI....
I'm using this block statement it takes more than 15 min .. the cursor query returns 20000 rec is any other way to update this ....pls give solution for this
declare
cursor c1 is select m_id from mem where del_status='N' and exists(select 1 from mem_alb where ma_id =mem_id) and exists (select 1 from mem_us where mu_m_id=m_id and MU_USED =0);
begin
for idx in c1 loop
update mem_us set (MUL_PUSED , MU_USED) =(select sum(1),sum(m_size) from mem_alb,mem_alb_poto where map_ma_id=ma_id and ma_m_id=idx.m_id and map_del_status=0 and mal_del_status=0) where mu_m_id=idx.m_id;
end loop;
end;Hello
Well, I'm in dire need of a double espresso so apologies if I've missed something, but I think that this is logically equivalent:
update
mem_us upd
set
(MUL_PUSED , MU_USED) =(select
sum(1),
sum(m_size)
from
mem_alb,
mem_alb_poto
where
map_ma_id=ma_id
and
ma_m_id=upd.m_id
and
map_del_status=0
and
mal_del_status=0
where
upd.del_status='N'
and
exists( select
1
from
mem_alb
where
ma_id =upd.m_id
and
exists( select
1
from
mem_us
where
mu_m_id=upd.m_id
and
MU_USED =0
);HTH

Thanks in advance.Thanks for your response.
Sorry for violating formatting. Since I am not aware of the format options in new environment.
I have created functional based index on SUBSTR(ACTION_TYPE, 1, 8).
The cost got reduced some what.But still the query is taking 40 minutes.
The following predicate it is returning 58296618 rows.
NOTE is not null
and NOTE2 is not null
and ACTION_TYPE is not null
LTC_SKU_UNIT is a view.
The following query is used for creating this view.
SELECT unit.VK_UNIT,
unit.MODEL,
unit.CLASS,
unit.LOB,
unit.LAST_UPDATE_DATE,
unit.DESCRIPTION
FROM LTC_GLOBAL.LTC_SKU_UNIT unit;
The following indexes are created on the LTC_GLOBAL.LTC_SKU_UNIT table.
CREATE INDEX LTC_GLOBAL.LTC_SKU_UNIT_IDX_CLASS ON LTC_GLOBAL.LTC_SKU_UNIT(CLASS)
CREATE INDEX LTC_GLOBAL.LTC_SKU_UNIT_IDX_MODEL ON LTC_GLOBAL.LTC_SKU_UNIT(MODEL)
CREATE INDEX LTC_GLOBAL.LTC_SKU_UNIT_IDX_UPDATE_DATE ON LTC_GLOBAL.LTC_SKU_UNIT(LAST_UPDATE_DATE)
CREATE UNIQUE INDEX LTC_GLOBAL.LTC_SKU_UNIT_PK ON LTC_GLOBAL.LTC_SKU_UNIT(VK_UNIT, MODEL, CLASS)
Is there any way to rewrite the query to improve the performance. Any suggestions to improve the performance.
Please help me.
Thanks in advance. -

Also
http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:1547006324238
may be of some benefit.
This all assumes that the function call is what is actually causing you problems (perhaps a bad assumption). You should be running a trace (TKPROF or AWR or something) to get an idea of why this query is actually causing you problems.
Also, as you are new to the forum, please read the FAQ so you learn things like using the tags to preserve the formatting of your code like i did above. -
Fine tunning the query which uses /*+ USE_CONCAT */ table hint
Some of the queries in our application uses the /*+ USE_CONCAT */ table hint which takes huge time for the execution in Oracle database.when we fire the below query in 250Million production database it takes approx.3min for the execution.
Because of this we are facing a performance issue in the application.
Below is the sample query :
SELECT /*+ USE_CONCAT */ * FROM DI_MATCH_KEY WHERE NORM_COUNTRY_CD = 'US'
AND ((( NORM_CONAME_KEY1 ='WILM I' OR NORM_CONAME_KEY2 = 'WILM I' OR NORM_CONAME_KEY23 = 'WILM I'
OR NORM_CONAME_KEYFIRST ='WILLIAM' ) AND NORM_STATE_PROVINCE = 'CA' ) OR NORM_ADDR_KEY2 = 'CALMN 12 3 OSAI')
Regarding the indexes almost for all the columns combination for the above sql index already created in table.
Your suggestions will be appreciated
Thanks,

Hi,
I am having below two queries. 2nd query is taking more time & it gives time out error. Can anybody tell how to fine tune below query. Thanks.
1st Query.
SELECT EKETEBELN EKETEBELP EKETETENR EKETEINDT

DESCRIBE TABLE I_EKET LINES V_ZLINES.
IF V_ZLINES > 0.
2nd Query.
SELECT EKKOEBELN EKKOAEDAT EKKOLIFNR EKPOEBELP EKPO~MATNR

Help in fine tuning this query
My query id this,
select a.event_id,a.document_id
from sample_transaction a
where exists (select 1 from sample_transaction b where b.event_id <> a.event_id and b.document_id = a.document_id );
The execution plan is like this,
SELECT STATEMENT Cost = 5596
FILTER
TABLE ACCESS FULL SAMPLE_TRANSACTION
TABLE ACCESS BY INDEX ROWID SAMPLE_TRANSACTION
INDEX RANGE SCAN I_SAMPLE_TRANSACTION_FK_EVT
There are 6 million records in the table.
How can i fine tune this query so that i get the results
Example is
my table has
EVENT_ID DOCUMENT_ID
100 200
100 200
101 201
102 201
103 203
104 203
105 204
105 204
106 106
My result should be
EVENT_ID DOCUMENT_ID
101 201
102 201
103 203
104 203
nullBased on your select statement, you will bring back every row in sample_transaction where the document is referenced by more than one event. Looking at it another way, the only rows skipped are those where the document is only used by one event.
The full table scan is not necessarilly a problem since Oracle has to check all rows. You may improve performance if you add an index on document_id. That will allow Oracle to do a better query on the EXISTS clause. Remember to rebuild your statistics after adding the index. -
Dear All,
I am using 11g version. The query given below.
Sample Data:
Table1: KEY ( It has 4 million records and DUR_UK column is unique key)
PK
DUR_UK
1
BD|4|J650|01AB|0001LLA|N01005309106|01003014101|0H9ZN|0HB0T|6970189|30748R2|001000
2
BD|506001022502|06076001901|0G1GF|0HB0T|7270478|2035772C91|000100

Table2: Section (It has 12k records)
Column: FVC
Data: OHBOT
In table 1, there are 3 types of order for bold and underlined data. I need to get the PK, JVC from KEY table by JOINING with Section table based on bold and underlined field with FVC column.
I tired with below query but it takes long time and didnt complete. Becoz it go thru 4 million records 3 times.
SELECT A.PK,B.JVC
FROM SECTION B
INNER JOIN KEY A
ON (REGEXP_SUBSTR(A.DUR_UK,'[^|]+',1,9) = B.FVC OR REGEXP_SUBSTR(A.DUR_UK,'[^|]+',1,5) = B.FVC OR REGEXP_SUBSTR(A.DUR_UK,'[^|]+',1,4) = B.FVC;
The output could be like.
PK JVC
1 OHBOT
2 OHBOT
3 OHBOT
Can someone please help me out to fine tune.
ThanksHi,
In a relational database, each column of each row should contain 1 piece of information, not a delimted list of several items. This is so basic to database design that it's called First Normal Form. Relational database are designed to work with data that is in First Normal Form. Your table was not designed to work well, and it seems to be doing exactly what it was designed for. This problem (and many others, no doubt) would be much simpler and much faster if each of the |-delimited items was on a separate row.
If you must use the current design, avoid regular expressions. You don't need all the power of regular expressions in this problem; you can get the results you need faster using less powerful tools, such as LIKE, INSTR and SUBSTR.
Depending on your data and your requirements, you might try something like this:
WITH got_pos AS
SELECT k.pk, k.dur_uk
, s.jvc, s.fvc
, INSTR (k.dur_uk, '|', 1, 3) AS pos3
, INSTR (k.dur_uk, '|', 1, 4) AS pos4
, INSTR (k.dur_uk, '|', 1, 5) AS pos5
, INSTR (k.dur_uk, '|', 1, 8) AS pos8
, INSTR (k.dur_uk, '|', 1, 9) AS pos9
FROM section s
JOIN key k ON k.dur_uk LIKE '%|' || s.fvc || '|%'
SELECT pk, jvc
FROM got_pos
WHERE fvc IN ( SUBSTR (dur_uk, pos3 + 1, pos4 - (pos3 + 1))
, SUBSTR (dur_uk, pos4 + 1, pos5 - (pos4 + 1))
, SUBSTR (dur_uk, pos8 + 1, pos9 - (pos8 + 1))
Of course, without any sample data, I can't test this.
Oracle Text might help with this problem. I don't use it myself, but I believe it allows you to create indexes so that it's faster to find keywords (such as anyhting in section.fvc) anywhere in large strings (such as key.dur_uk). -

This is the Query and the query takes some mins. to run in prod environment.
From the Query plan ,I am not able to get any idea for optimization.
Now,Can you tell me which steps I need to follow to run it faster and which all modifications should be made?
