Complex Query which needs tuning

Hello :
I have a complex query that needs to be tuned. I have little experience in tuning the sql and hence taking the help of your guys.
The Query is as given below:

First thing that i notice in this query is you are Using Distinct as well as Group by.
Your group by will always give you distinct results ,then again why do you need the Distinct?
For example
WITH t AS
     (SELECT 'clm1' col1, 'contract1' col2,10 value
        FROM DUAL
      UNION ALL
      SELECT 'clm1' , 'contract1' ,10 value
        FROM DUAL
      UNION ALL
      SELECT 'clm1', 'contract2',10
        FROM DUAL
      UNION ALL
      SELECT 'clm2', 'contract1',10
        FROM DUAL
      UNION ALL
      SELECT 'clm3', 'contract1',10
        FROM DUAL
      UNION ALL
      SELECT 'clm4', 'contract2',10
        FROM DUAL)
SELECT distinct col1,col2,sum(value) from t
group by col1,col2Is always same as
WITH t AS
     (SELECT 'clm1' col1, 'contract1' col2,10 value
        FROM DUAL
      UNION ALL
      SELECT 'clm1' , 'contract1' ,10 value
        FROM DUAL
      UNION ALL
      SELECT 'clm1', 'contract2',10
        FROM DUAL
      UNION ALL
      SELECT 'clm2', 'contract1',10
        FROM DUAL
      UNION ALL
      SELECT 'clm3', 'contract1',10
        FROM DUAL
      UNION ALL
      SELECT 'clm4', 'contract2',10
        FROM DUAL)
SELECT col1,col2,sum(value) from t
group by col1,col2And also
AND SOL.STATUS_DATE BETWEEN '01-JUN-09' AND '30-JUN-09'It would be best to use a to_date when hard coding your dates.

Complex query advice needed

I have a mysql table that basically represents a log of daily events. I need to be able to get the total number of events for each week in a year. How can I efficiently query the database and tally the toal records for each week in a year, given that my events are recorded daily? Any advice would be much appreciated. Thanks.

Presumably the events have a timestamp.
One possibility (you need to deal with border conditions)
1. Find a function that returns day of the year from a timestamp (dayInYear)
2. Determine offset from beginning of year to 'first week' in year. (Offset)
3. week = (dayInYear(timestamp) - Offset)/7
4. Write a query that does a sum using group by on the week value.

How can i imrove peroformance of complex Query

How can i improve performance of complex Query
which used CASE WHEN , GROUP By Rollup
for example
SELECT CASE WHEN null then a
ELSE b END
FROM (
SELECT a,b,c,..........
FROM table1
UNION ALL
SELECT a,b,c,..........
FROM table2
GROUP BY ROLLUP a,b,c ,............
this query take 18 min to return 180000 record
is there is any way to improve the performance of this query

Hello
Have you considered using

Trying to form complex query - need help

I have a fairly complex query that I need to join the results of to show actual and goal by day. The actuals are an aggregation of records that get put in every day, while the targets are a single entry in range format indicating an active range for which the target applies. I'm working on a query that will put things together by month and I'm running into a snag. Can someone please point out where appropriate naming needs to go to get this to come together?
This one works:
(select DATE_INDEX, SUM(LDS) as TTLLDS, SUM(TONS) as TTLTONS from
    (select DATE_INDEX, VEH_LOC, SUM(LDS) as LDS, SUM(WT) as TONS from
       (select c.DATE_INDEX, c.VEH_LOC, COUNT(j.LOAD_JOB_ID) as LDS,
             CASE WHEN SUM(w.SPOT_WEIGHT) = 0 THEN SUM(j.MAN_SPOT_WT)
                  ELSE SUM(w.SPOT_WEIGHT)
              END as WT
          from TC c, TC_LOAD_JOBS j, LOAD_RATES r, SPOT_WEIGHTS w
         where c.TC_ID = j.TC_ID and j.LOAD_RATE_ID = r.LOAD_RATE_ID
           and c.DATE_INDEX = w.DATE_INDEX and j.LOAD_RATE_ID = w.LOAD_RATE_ID
           and c.VEH_LOC in (select ORG_ID from ORG_ENTITIES where MNG_ORG_ID = 200)
           and c.DATE_INDEX between to_date('08/01/2010','MM/DD/YYYY') and to_date('07/31/2011','MM/DD/YYYY')
         group by c.DATE_INDEX, c.VEH_LOC
        union
        select c.DATE_INDEX, c.VEH_LOC, COUNT(j.JOB_ID) as LDS,
             DECODE(SUM(j.AVG_SPOT_WEIGHT),0,SUM(r.BID_TONS),SUM(j.AVG_SPOT_WEIGHT)) as WT
          from TC_3RDPARTY c, TC_3RDPARTY_JOBS j, LOAD_RATES r
         where c.TC_ID = j.TC_ID and j.LOAD_RATE_ID = r.LOAD_RATE_ID
           and c.DATE_INDEX between to_date('08/01/2010','MM/DD/YYYY') and to_date('07/31/2011','MM/DD/YYYY')
           and j.FACTORY_ID in (select ORG_ID from ORG_ENTITIES where MNG_ORG_ID = 200)
         group by c.DATE_INDEX, c.VEH_LOC)
      group by DATE_INDEX, VEH_LOC)
group by DATE_INDEX)Now I need to add in the following query:
select (u.MACH_TPH_D+u.MACH_TPH_N)/2 as MTPH_TGT, (u.LABOR_TPH_D+u.LABOR_TPH_N)/2 as LTPH_TGT
     from UTIL_TARGET_LOADERS u
    where u.ORG_ID in (select ORG_ID from ORG_ENTITIES where MNG_ORG_ID = 200)The join needs to be based on VEH_LOC and DAY in the form:
   ... WHERE u.ORG_ID = x.VEH_LOC
          AND x.DATE_INDEX between u.START_DATE and NVL(u.END_DATE,sysdate)I had one that worked just fine when only one entity was involved; the complication arises in that this is a division-level report so I have to individually resolve the subordinates and their goals before I can aggregate. This is one of two queries I need to tie together using a WITH clause so I can pivot the whole thing and present it in month-by-month fashion. When I try to tie it together like the query below, I get: invalid relational operator.

          from TC c, TC_LOAD_JOBS j, LOAD_RATES r, SPOT_WEIGHTS w

    where ttls.DATE_INDEX beween u.START_DATE and NVL(u.END_DATE,sysdate)
      and ttls.VEH_LOC = u.ORG_ID
group by ttls.DATE_INDEXI know this is a nested mess, as it has to grab the production from two tables for a range of VEH_LOC values and sum and aggregate by day and VEH_LOC, then I have to try and match that to the targets based on VEH_LOC and day. My final query is to aggregate the whole mess of sums and averages by month.
I'd appreciate it if someone can point me in the right direction.

Figured it out.

NEED HELP IN REDUCING THE LENGTH OF QUERY WHICH IS ATTACHED IN A FILE PL_SQ

Hi Everyone,
THANKS FOR POSTING THE REPLIES FOR MY LAST THREAD. THAT REALLY HELPED. I CAME BACK AGAIN BECAUSE I NEED HELP FROM THIS FORUM IN REDUING THE LENGTH OF MY QUERY WHICH I HAD GIVEN BELOW. i DIDN'T HAD THE CHOICE OF ATTACHING A FILE OF MY DATA HERE.ITS VERY HUGE DATA SO I AM NOT ABLE TO PROVIDE ATLEAST SAMPLE DATA BECAUSE THE COLUMNS ARE OVERLAPPING IF I AM PASTING THE DATA HERE. I HOPE IT WILL BE UNDERSTANDABLE. THE QUERY WHICH I WROTE IS TOO LONG AND TAKING HOURS TOGETHER TO RUN AND DISPLAY RESULT. IT WOULD BE A GREAT FAVOUR TO ME IF ANYONE CAN REDUCE THE LINES IN MY QUERY AND MAKE IT RUN FAST....PLEASE I WAS NOT KNOWING THE WAY HOW TO MAKE IT SHORT. IT HAS MANY LOGICS IN IT... :? PLEASE SUGGEST ME IF THERE IS ANY OPTION FOR ATTACHING A FILE SO THAT I CAN SEND MY SAMPLE DATA...

Problem is enire output of the query is perfectly fine but in the second row at column effective_start_date insted of 19-NOV-2007 in need a value from another query. there must not be any change in rest of the columns data including first row.
i.e select ORIGINAL_DATE_OF_HIRE from per_all_people_f
where employee_number = '10620'
and rownum < 2
---------------------------OUT PUT----------------------------

Is there is any approach to get this thing.

Thanks,
Chetan
Options:
1) You can use
BCP command to export result to excel
2) Insert into excel by using OPENROWSET
3) Use Import and Export Wizard and provide SQL query as source and Excel as destination

http://www.oracle.com/webfolder/technetwork/tutorials/obe/jdev/obe11jdev/ps1/ejb/ejb.html#t2s1
But above application is based on "Entities based on Tables" but my requirement to build a service based on query which contains multiple tables which means I want to create a generic one...
please let me know what I need to change or please provide any link for docs.

Hi Desmukh,
I want to create a wsdl for complex queries based on ADF fusion applicaiton using EJB3.0 and JPA...!
the link which you provided 'entity with tables' which is restricting for my requirement but I want similar implementation for complex queries :(

Complex query help

Hope someone can help with this.
I have a database structure :
table : photos
Photo_ID (PK)
Title
Orientation
etc
table : keywords
Keyword_ID (PK)
Keyword
Category
table : photokeywords
Photo_ID
Keyword_ID
I have a search page that uses checkboxes allowing users to
search on keywords, that returns any photos which match the
selected keywords.
In the search page the checkboxes are created using an array,
and are displayed as :
//Display the checkbox
echo "<td width=\"2%\">";
echo "<input type=\"checkbox\"
class=\"tickbox_".$row_type."\"";
if (in_array($keyword['Keyword_ID'],$photokeywords)) { echo
" checked"; }
echo " name=\"ckbox[".$keyword['Keyword_ID']."]\"
id=\"ckbox[".$keyword['Keyword_ID']."]\">";
echo "</td>\n";
Someone kindly helped me out some time ago to write a fairly
complex (for me!) query that counts the matches, so enabling the
results to be ordered by the number of matches, ie the most
relevant matches first.
The code for this is :
//db session
mysql_select_db($database_Photolibrary, $Photolibrary);
if (isset($_GET['ckbox'])){
// get profile keys
$ckbox = array_keys($_GET['ckbox']);
// sql string
$sql = 'SELECT *, Count(*) As rank FROM photos, photokeywords
WHERE photos.Photo_ID =
photokeywords.Photo_ID AND photokeywords.Keyword_ID IN(' .
implode(',', $ckbox).') GROUP BY
photos.Photo_ID ORDER BY rank DESC, Title';
$photos = mysql_query($sql) or die(mysql_error());
$row_photos = mysql_fetch_assoc($photos);
@$totalRows = mysql_num_rows($photos);
The page I have is using Tom Muck's pages list and horizontal
looper behaviours to display the results.
Everything works fine except the pages list, where there is
more than one page of results. I've emailed the ever helpful Tom
who has advised me that the query may need to be constructed in DW,
as the Pages List behaviour relies on DW's code to manage the
paging.
So I've gotten as far as the basic query code :
<?php
mysql_select_db($database_Photolibrary, $Photolibrary);
$query_photos = "SELECT *, Count(*) As rank FROM photos,
photokeywords WHERE photos.Photo_ID = photokeywords.Photo_ID AND
photokeywords.Keyword_ID IN(' . implode(',', $ckbox).') GROUP BY
photos.Photo_ID ORDER BY rank DESC, Title";
$photos = mysql_query($query_photos, $Photolibrary) or
die(mysql_error());
$row_photos = mysql_fetch_assoc($photos);
$totalRows_photos = mysql_num_rows($photos);
?>
But am unsure where I need to call the ckbox values,
previously :
if (isset($_GET['ckbox'])){
// get profile keys
$ckbox = array_keys($_GET['ckbox']);
in the DW construction.
I've been playing around with different things in the query's
variables, such as
Name : Keyword_ID
Default value : 1
Run time value : $_GET['ckbox']
but to no avail.
If anyone can help out with this it'd be much appreciated.
Cheers.

Complex query

I am novice in PL/Sql. I need some help in writing a complex query.
I imagine the following table structure.
Type(string) Date(date) count(int)
Given a date range
The query needs to group the records on type and return the record (type and count) which has the max date (its just date, no time is involved) for each group (which is based on type) . If there are more than one records which have the max date then the average count should be returned for that type
i would be glad if someone could give any ideas as to how to go about this query. Thanking you in advance.
regards.

Heres the query ... Forget the period .... wht this query is supposed to do is group on assigned ki for a given date range. then it has to get the value which is for the last record for that Ki in the date range. If there are 2 records which have max date then it should give an average.
e.g
assignedKI / date / value
a 1st may 2008 10
b 2nd may 2008 12
c 1st may 2008 13
a 30 - apr-2008 16
b 4th may 2008 17
a 1st may 2008 20
The query should return
a 1st may 2008 15 (which is the average as there are 2 values for the max date for a)
b 4th may 2008 17
c 1st may 2008 13
the following query doesnot work ....
SELECT
kiv2.assigned_k_i,
kiv2.ki_name,
kiv.period,
max( kiv2.ki_value_date) ,
avg(kiv2.ki_value)
FROM
SELECT
assigned_k_i,
period p1,
TO_CHAR(ki_value_date, period) period,
MAX(ki_value_date) ki_value_date
FROM
v_ki_value,
(select ? period from dual)
WHERE
(status = 'APPROVED' OR status = 'AUTOAPPROVED')
AND ( trunc(to_date(to_char(ki_value_date, 'DD/MM/YYYY'), 'DD/MM/YYYY')) >= ?)
AND ( trunc(to_date(to_char(ki_value_date, 'DD/MM/YYYY'), 'DD/MM/YYYY')) <= ?)
AND (INSTR(?, TO_CHAR(assigned_k_i)) > 0)
GROUP BY
assigned_k_i,
TO_CHAR(ki_value_date, period)
) kiv,
v_ki_value kiv2
WHERE
kiv.assigned_k_i = kiv2.assigned_k_i
AND to_char(kiv.ki_value_date, kiv.p1) = to_char(kiv2.ki_value_date, kiv.p1)
GROUP BY
kiv2.assigned_k_i,
kiv2.ki_name,
kiv.period,
kiv2.ki_value
ORDER BY
kiv2.assigned_k_i

Complex Query in toplink descriptor

I have a complex query with "Order by" and "Max" aggregation function and I am trying to convert it to a named query. I am using toplink descriptor in Jdeveloper 11G.
1. Is it possible to write a named query which returns values from more than two different table?
2. how to specify Max operation in the Toplink descriptor.
Here is my Query
select * from table1 t1 ,table2 t2
where
t1.id = t2.id and
t1.name ='Name' and
t1.status<>'DELETE' and
t2.a_id = (select max(a_id) from table2 t21 where
t21.a_id = t1.id and
group by id)

TopLink supports sub-selects through sub-queries in TopLink Expressions, and through JPQL. I'm not sure on the JDev support though, you may need to use a code customizer or amendment to add the named query.

How to store data from a complex query and only fresh hourly or daily?

We have a report which runs quite slow (1-2 minutes) because the query is quite complicate, so we would like to run this query daily only and store in a table so for those procedures that need to use this complex query as a subquery, can just join to this table directly to get results.
However, I am not sure what kind of object I should use to store data for this complex query. Is data in global temp table only persist within transaction? I need something that can persist the data and be access by procedures.
Any suggestions are welcome,
Cheers

Thank you for your reply. I looked at the materialized view earlier on, but have some difficulties to use it. So I have some questions here:
1.The complex query is not a sum or aggregate functions, it just need to get data from different tables based on different conditions, in this case is it still appropriate to use meterialized view?
2.If it is, I created one, but how to use it in my procedure? From the articles I read, it seems I can't just query from this view directly. So do I need to keep the complex query in my procedure and how the procedure will use the meterialized view instead?
3. I also put the complex query in a normal view, then create a materialized view for this normal view (I expect the data from the complex query will be cache here), then in the procedure I just select * from my_NormalView, but it takes the same time to run even when I set the QUERY_REWRITE_ENABLED to true in the alter session. So I am not sure what else I need to do to make sure the procedure use the materialized view instead of the normal view. Can I query from the Materialized View directly?
Below in the code I copied from one of the article to create the materialized view based on my normal view:
CREATE MATERIALIZED VIEW HK3ControlDB.MW_RIRating
PCTFREE 5 PCTUSED 60
TABLESPACE "USERS"
STORAGE (INITIAL 50K NEXT 50K)
USING INDEX STORAGE (INITIAL 25K NEXT 25K)
REFRESH START WITH ROUND(SYSDATE + 1) + 11/24
NEXT NEXT_DAY(TRUNC(SYSDATE), 'MONDAY') + 15/24
enable query rewrite
AS SELECT * FROM HK3ControlDB.VW_RIRating;

Complex query crashing database!

Hi
Our 10g database runs on Windows 2003 (with 32 GB RAM on server).
Whenever a user is running a particular complex query, the database just crashes suddenly.
In fact, it doesn't write anything in alert log file for any problem.
The user starts the query, it runs for sometime, then suddenly database crashes!
Only way to work there after is to restart the database.
Although I asked the user to not to run that query again but it is generated by some application which may generate similar query again!
So, how I can prevent database from crashing again?
Will creating a resource profile to allocate finite resource help? Problem is since database crashes so suddenly, I can't find any info from log files!
Thanx

The database instance crashes. We have to start the ORACLE.EXE again to up the database.
Here is last few lines of the alert.log

Working with multiple results of a complex query

Hi all!
As I "advance" in learning PL/SQL with oracle, I now get stuck in handling multiple results of a complex query. As far as I know, I cannot use a cursor here, as there is no table where the cursor could point to.
Here is the concept of what I want to do (pseudocode):
foreach result in SELECT * FROM table_1, table_n WHERE key_1 = foreign_key_in_n;
    -- do someting with the resultHere is my attemt, that freezes the browser gui and throws an internal database error:
declare
    type t_stock is record(
            baggage_id baggage.baggage_id%type,
            section_id sections.section_id%type,
            shelf_id    shelves.shelf_id%type
    v_stock t_stock;
    rcnt number(2);
begin
dbms_output.put_line(TO_CHAR(rcnt));
loop
     SELECT COUNT(*) INTO rcnt FROM (
               SELECT baggage.baggage_id, sections.section_id, shelves.shelf_id
               FROM baggage, sections, shelves
               WHERE baggage.baggage_id = sections.contained_baggage_id
                    AND shelves.is_connex_to_section_id = sections.section_id);
     IF rcnt <= 0 THEN
          exit;
     END IF;
     SELECT baggage.baggage_id, sections.section_id, shelves.shelf_id INTO v_stock
     FROM baggage, sections, shelves
     WHERE baggage.baggage_id = sections.contained_baggage_id
          AND shelves.is_connex_to_section_id = sections.section_id
          AND ROWNUM < 2;
     UPDATE sections SET contained_baggage_id = NULL WHERE section_id = v_stock.baggage_id;
     commit; -- do I need that?
end loop;
END;
/So, is there a way to traverse a list of results from a complex query? Maybe without creating a temporary table (or is that the better way?).
regards, Alex
I reformatted the code
pktm

Ok, here are the details:
The tables are used to model kind of a transport system. There are terminals connected with sections that may contain 1 piece of baggage. The baggage is moved by a procedure through a transport system. After each of these "moving steps", I check if the baggage is in front of the shelf it should be in.
[To be honest, the give statement doesn't contain the info, in which shelf the baggage wil bee inserted. That was spared out because of the lack of a working piece of code :)]
But: if we consider the fact, that a baggage is in front of such a shelf in the way, that it should be put in this shelf, then all this makes some sense.
- move baggae through a transport system
- see if you can put baggage into a shelf
In order to "put baggage in a shelf", I need to remove it from the transport section. As the transport system is not normalized, I need to update the section where the baggage was in.
Uhm... yes it's a task that doesn't make too much sense. It seems to be some kind of general spirit in university homework :)
But: the FOR r IN (Statement) lloks good. I'll use that.
And, the ROWNUM < 2 is used to limit the size of the result to 1, there is no need to have a specific ordering. It's just because - afaik - oracle doesn't have a limit clause. I would appreciate your help if you know a better way to do limit resultsets.
best regards, Alex
