Help to tune nested query
Hi I have a following type of query which is using inline views .
select a,b,c,d,e,f
from
(select a,b
from (select a,c from t)),
(select c,d
from (select d,c from t1))
What would be best approach to tune these type of queries?
Can we use Global temp Table these queries
-kuldeep
What do you mean by tune. What do you want to do.
select a,b,c,d,e,f
from
(select a,b
from (select a,c from t)),
(select c,d
from (select d,c from t1))you dont have any join condition. you are doing a Cartesian join here. is that what you want to do. this can be very simply writern like this.
select a,b,c,d from t,t1and where does the column e and f come from. if you wnat answers give us the questions properly.
do you have any idea what a global temporary table? what made you think it will help you here?
Karthick.

Please help me.
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. -
I am currently using the query:
SELECT vs.serial_num,
nvl(sum(events), 0) as vs.events,
nvl(get_part_count(vs.fiscal_year, vs.vehicle_type, vs.serial_num), 0) as unique_parts,
nvl((get_part_count(vs.fiscal_year, vs.vehicle_type, vs.serial_num)/total_parts), 0) as percent_unique_parts,
FROM vehicle_stats vs
WHERE vs.vehicle_type = 'truck'
AND vs.fiscal_year = 2000
GROUP BY vs.serial_num
in a stored procedure that returns a ref_cursor to a web application. As you can see I'm calling get_part_count twice, once for the raw number and again for the percentage. Is there a simple way to eliminate one of these calls and still retain the return same cursor?
Thanks in advanceIf you have a primary key for this table, you could try this :
SELECT vs.serial_num,
nvl(sum(events), 0) as vs.events,
nvl(gp.gpc, 0) as unique_parts,
nvl(gp.gpc/total_parts), 0) as percent_unique_parts,
FROM vehicle_stats vs,
(SELECT pk_column, get_part_count(vs.fiscal_year, vs.vehicle_type, vs.serial_num) gpc FROM vehicle_stats) gp
WHERE vs.vehicle_type = 'truck'
AND vs.fiscal_year = 2000
AND vs.pk = gp.pk
GROUP BY vs.serial_num -

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,
Can you please help me tune a query?
I have a dimension table PRODUCT which is having product data with millions of rows and another table (fact table) with more than millions of rows and it is called PRODUCT TRANSACTION.
The PRODUCT TRANSACTION table has multiple rows for a given product with multiple issue dates. EX.
PRODUCT ISSUE DATE
A 10/28/2008
B 11/02/2008
C 05/28/2008
D 06/27/2008
E 07/28/2008
I am doing JOIN between PRODUCT (dimension table) and fact (PRODUCT TRANSACTION TABLE) and just want a minimum of ISSUE DATE (means only one record from fact table for each product in dimension table).
I have written query as
SELECT PRODUCT_ID FROM
PRODUCT_TRANSACTION AS PT
INNER JOIN PRODUCT P ON
P.PRODUCT_ID IN (SELECT PT.PRODUCT_ID FROM
SELECT PT1.PRODUCT_ID, MIN (PT1.ISSUE_DATE) AS MINC
FROM PRODUCT_TRANSACTION PT1
GROUP BY PT1.PRODUCT_ID) B)
This query takes forever. Is there a better way to accomplish this?
Please suggest.Try this:
SELECT
PRODUCT_ID,
min(issue_date) keep(dense_rank first order by issue_date)
FROM
PRODUCT_TRANSACTION
GROUP BY PRODUCT_IDRegards,

reverse(substr(reverse(ms.name),instr(reverse(ms.name),'-')+1)) cluster_name"{code}
This is the same as:
{code}SUBSTR(ms.name, 1, INSTR(ms.name, '-', -1) - 1){code}
{code}select max(to_char(create_datetime,'mm/dd/yyyy')){code}
This will ensure that 2nd December 2008 is counted as being later than 1st December 2009 - is that absolutely correct? Did you not mean this instead?:
{code}SELECT MAX(TRUNC(create_datetime)){code}
{code}
AND dad.device_id = dev.id(+)
AND dev.status_id = ds.id(+)
AND dev.model_id = hm.id(+)
AND dev.id = dp.paired_from_id(+)

{code}
Those outer joins are useless! When you say "outer join tableB to tableA on the join cols and then filter the rows where tableB.some_col = some_value", what you're really saying is "inner join tableB to tableA on the join cols and tableB.some_col = some_value".
If you're wanting to do full outer joins use ANSI join syntax *or* do the outer joins first in a sub-query and then join that to the rest of the tables. -

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?
Thanks.

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 do tune sql query? Can somebody help me in this? Atleast prescribe a reference book.
I am not able understand How to analyze tkproof output.Check out asktom.oracle.com
Lot's of threads on interpreting tkprof output - no simple easy solution here.

Executing nested query contains ORDER BY:Help Needed
I have a database in ORACLE 8.0 enterprise
edition in HP-UX. I am trying to execute the following query
"select * from ( select * from temptable order by value desc) where rownum < 5"
and I am getting the following error
"missing right parenthesis"
This syntax is given in the Oracle user guide
under sql commands section and it is not
working.
Similar query is working on Oracle 8.1 running on Win NT.
Does any body throw some light.
Thanks in advance
-rajYour query works fine in Oracle 8i:
SELECT *
FROM (SELECT *
FROM temptable
ORDER BY value DESC)
WHERE ROWNUM < 5;
However, prior to Oracle 8i, in Oracle 8.0, it is not allowed to have an ORDER BY clause within a nested query. So, in Oracle 8.0, a query like the above cannot work. However, the following, with the ORDER BY clause in the outer query will work:
SELECT *
FROM temptable a
WHERE 5 >=
(SELECT COUNT (*) + 1
FROM temptable b
WHERE b.value > a.value)
ORDER BY a.value DESC;
null

Hi there, I'm busy with a documentary (90min cinema/tv production) since one year. I started with CS06 on a Macbook pro (maverick, 15' 2,8GHZ). Everything was fine and I barely never had a problem - despite the fact that the computer was quiet slow.
