Complex Query - Need Solution
Hello,
I am having trouble in getting the result at the bottom. I have two tables as below. I need Idno,transdt,cycdt,amt from joining two tables.
The criteria is that if the transdt greater than same month of cycdt then we need get the next month cycdt and corresponding amount for that, if it is less than or equal to same months cycdt then get the same months cycdt and amt.
Table1
idno,trandt
12345,04/15/2005
12345,04/22/2005
12345,07/03/2005
12345,09/10/2005
3421,03/05/2005
3421,05/06/2005
3421,07/04/2005
3421,07/15/2005
Table2
idno,cycdt,amt
12345,02/10/2005,15.43
12345,03/13/2005,40.84
12345,04/18/2005,10.10
12345,05/24/2005,13.00
12345,06/16/2005,20.89
12345,07/18/2005,12.12
12345,08/17/2005,10.89
12345,09/17/2005,12.87
12345,10/16/2005,13.89
3421,05/10/2005,15.00
3421,06/11/2005,20.00
3421,07/11/2005,14.15
3421,08/12/2005,15.54
Expected result.
12345,04/15/2005,12345,04/18/2005,10.10
12345,04/22/2005,12345,05/24/2005,13.00
12345,07/03/2005,12345,07/18/2005,12.12
12345,09/10/2005,12345,09/17/2005,12.87

3421,07/15/2005,3421,08/12/2005,15.54
I really appreciate if someone can give a solution for this using a query.
Thanks

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.

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.

JPA: Complex query needed to load object / special processing on store
I have what I think is a tricky situation with an ORM scenario, and I am wondering what I need to do to get JPA to work with this situation:
I have a table that looks like:
key_with_rev_id INTEGER (sequence based, unique pk)
key_id INTEGER (sequence based)
rev_id INTEGER (sequence based, with key_id forms unique index)
del_flag VC(1)
+ various data fields
The object would contain these attributes (preferably):
key_id (as the "unique" id)
max_rev_id (transient, defaults to null)
+ various data attributes
When I load it -- for max_rev_id = null, it should basically do this:
select <data fields> from revved_table
where key_id = <object.key_id>
and rev_id = (select max(rev_id) from revved_table where key_id = <object.key_id>)
and del_flag is null or del_flag = 'N'
The query is a little more complex when max_rev_id is not null, but same idea.
Now then -- when I store the object, whether it is to insert or update, I want it to always insert rows, with the key_with_rev_id and rev_id values from the corresponding sequences. (On insert, it will also use another seq to populate key_id). When I delete, I also want to insert a new row, but set del_flag = 'Y'
Is this too complex for JPA such that it would be a huge hassle, or is there an elegant way to set this up?
My apologies for any unusual terminology in the above -- I am quite new to JPA.
Thanks,
ken clarkDoes anyone have any suggestions as to where to start looking?

Regards,
BMPFirst 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.

1. How to create an explain plan with rowsource statistics for a complex query that include multiple table joins ?
When multiple tables are involved , and the actual number of rows returned is more than what the explain plan tells. How can I find out what change is needed in the stat plan ?
2. Does rowsource statistics gives some kind of understanding of Extended stats ?You can get Row Source Statistics only *after* the SQL has been executed. An Explain Plan midway cannot give you row source statistics.
To get row source statistics either set STATISTICS_LEVEL='ALL' in the session that executes theSQL OR use the Hint "gather_plan_statistics" in the SQL being executed.
Then use dbms_xplan.display_cursor
Hemant K Chitale -
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) ,

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,
CheersThank 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;

EJB-QL--- Complex Query --- Two Entites
hi
Can i write Complex Query in EJB-QL
between two entities...
have any buddy wrote the same....
i badly require the same...
bye
RAJRaj -- OC4J will support EJB-QL soon but not yet. You can look at
Re: Data Integrity
for more details.
Now, as for complex query, you may still be able to do this in the current version through the orion-ejb-jar.xml. You can
include complex SQL there in the finder methods.
What exactly do you need to do?

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

You can combine similar coding and use an OR condition for the parts that are different. I left the 'K' vin comparison in both years for readability.
I was not able to fully test my code but I believe that it will work as is. I hope it helps. If you are happier with the UNION you may want to investigate the WITH clause as you can query a subset of data twice, rather than the full data set.

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
pktmOk, 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 -
Hi,
I'm new in Enterprise javabeans, I have been looking for (almost five days) the
best way to get the result for a complex query. I tried with example Weblogic
BeanManaged. I put the query directly in a method in entityBean class with prepareStatament
and that worked.
But, I have to evaluate the best way to get result with EJB's. So, I think that
I have to evaluate others like containerManaged, in this case I have to define
each entity Bean and relationships and everything, isn't it?
Is there another way to develop it with good results? and fast?
If someone have any good idea to develop a solution with EJB's for this query.
I'm really appreciate it.

Hola/Hello Yosemarlyn,
You can utilize EJB 2.0 CMP to model the query that you specified. You
would model
the business domain as CMP Entity beans and then specify the various
relationships
among them. You actually may get an increase in performance by utilizing
CMP/CMR
in WebLogic due to the new features such as relationship caching, optimistic
concurrency
strategy support, etc. Utilizing these features will drastically reduce
the number
of SQL Joins (and overall hits to the database, due to caching). Below
are various
links for learning more:

Complex query design suggestions
Hi, I should first of all point out I'm new to pl/sql and struggling a bit so any help you can provide is really appreciated.
I have the requirements for a complex query the conditions of which are as follows
Four tables involved
ProductGroups, Products, Stock, StockMovements
Query requirements psudeocode (broken into bits to make things easier)
/* CODE */
Select distinct products
where productgroup.group between 'a' and 'z'
And stock.location = 'x'
And stock.qty > 0
For each product
_myDate = currentdate - 1 year
stkMvt= Select * from StockMovements where product = product
If(select count(*) from stkMvt where code = 'A' and type = 'A' and source = 'A' and stkMvt.date > _myDate) > 0)
-- exclude row / move next product
End If
If (select count(*) from stkMvt where code = 'B' and type = 'B' and source = 'B' and stkMvt.date> _myDate) > 0)
-- exclude row / move next product
End If
If (select count(*) from stkMvt where code = 'C' and type = 'C' and source = 'C' and Qty > 0 and stkMvt.date> _myDate) > 0)
-- exclude row / move next product
End If
If (select max(stkMvt.date) from stkMvt where code = 'D' and type = 'D' and source = 'D' < _myDate)
If ( select max(stkMvt.date) from stkMvt where ((code = 'E' and type = 'E' and source 'E')
Or (code = 'F' and type = 'F' and source = 'F')
Or (code = 'G' and type = 'G' and source = 'G')) > _myDate )
-- exclude row / move next product
End If
End If
-- Get the fields to return
Qty1 = Select coalesce(sum(qty),0) from stkMvt where code = 'H' and type = 'H' and source = 'H'
Qty2 = Select coalesce(sum(qty),0) from stkMvt where code = 'I' and type = 'I' and source = 'I'
Qty3 = Select coalesce(sum(qty),0) from stkMvt where code = 'J' and type = 'J' and source = 'J' and stkMvt.date between :fromDate and :toDate
LastDate = Select max(stkMvt.Date) from stkMvt
StkQty = Select Qty from Stock where product = product
AllQty = Select AllQty from Stock where product = product
FreeQty = StkQty - AllQty
Value = Select value from Stock
Select group, product , Qty1, Qty2, Qty3, LastDate, StkQty, AllQty, FreeQty, Value INTO table/cursor
Loop
Return table / cursor
/* CODE END */
Any guidance about the best way to achieve the above in an SP or Package would be massively helpful,
Thanks in advance
Scott.Agreed, it is a mess and I was looking the other way when it was dumped into my lap to deal with unfortunately. Any pointers in the right direction would really be helping me out.

"STMOV_PERIOD" NUMBER(5,0)
Relationships are as follows
CMGROUP.CMGRP = CMPROD.CMP_GROUP (One to Many)
CMPROD.CMP_PRODUCT = STOCK.STK_PRODUCT (One to Many)
STOCK.STK_LOC = STMOVE.STMOV_LOC (Many to Many)
STOCK.STK_PRODUCT = STMOVE.STMOV_PRODUCT (Many to Many)
As for the requirements well they aren't straightforward but the gist of it is to return a ref cursor to a crystal report from an oracle package. The ref cursor is to contain the following
select products that are
1) In stock
2) For a specific location
3) In a range of product groups
4) That either have a manual stock receipt movement within the last 12 months
5) Or do not have the following stock movement within the last 12 months
a. PO Receipt
b. WO Receipt
c. Stock Acquisition Receipt
Of the results I need to
1) Display the group
2) Display the product
3) Sum the Qty of WO Receipts from the 1st of the month (13 Months Ago) until today
4) Sum the Qty of PO Receipts from the 1st of the month (13 Months Ago) until today
5) Sum the Qty of Stock Transfers from the 1st of the month (13 Months Ago) until today
6) Display the most recent stock movement date
7) Display the current stock quantity
8) Display the allocated stock quantity
9) Display the available stock quantity
10) Display the stock value
Movement code definitions as follows
