Complexe query
I need some help with a query that is a bit complex. Given the following table:
Nrcrt Name Medie
1 John 8,25
2 Wu 3,25
3 Abe 4,55
4 Willard 6,15
5 Khamis 8,75
6 Ash 9,85
7 Horace 10
8 Mada 6,30
9 Isla 3
10 Kham 9.90
Now I want to select all the data from this table, order by medie, then separate it into groups of 2, it should look something like:
select * from tablename order by medie
but I don't know how to separate it by groups of 2, so it would look something like:
7 Horace 10
10 Kham 9.90
6 Ash 9.85
5 Khamis 8.75
1 John 8.25
8 Mada 6.30
and so on for the rest of the data... any help would be appreciated

@*Frank Kulash*, thanks a lot, exactly what I needed. But I have one more request, if it can be done. It does the grouping in 2, but can I add a generic title for each group? I mean for first group is GROUP 1, then second GROUP 2, and this must be done by the query itself (I refer to the index 1,2,3 and so on)Sure, the column called grp has the values 1, 2, 3, ....
You can use
'GROUP ' || grpto transform that into 'GROUP 1', 'GROUP 2', ...
For example:
WITH got_r_num AS
SELECT nrcrt, name, medie
, ROW_NUMBER () OVER (ORDER BY medie DESC) AS r_num
, CEIL ( ROW_NUMBER () OVER (ORDER BY medie DESC)
/ 2
) AS grp
FROM t
-- WHERE ... -- any filtering goes here
SELECT nrcrt, name, medie
, CASE
WHEN MOD (r_num, 2) = 1
THEN 'GROUP ' || grp
END AS label
FROM got_r_num
GROUP BY GROUPING SETS (
(nrcrt, name, medie, r_num, grp)
, (grp)
ORDER BY grp
, r_num
;With the sample data Sudhakar posted, this produces:
. NRCRT NAME MEDIE LABEL
7 Horace 10 GROUP 1
10 Kham 9.9
6 Ash 9.85 GROUP 2
5 Khamis 8.75
1 John 8.25 GROUP 3
8 Mada 6.3
4 Willard 6.15 GROUP 4
3 Abe 4.55
2 Wu 3.25 GROUP 5

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

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)

Any help will be much appreciated.
iI guess I should use DBMS_SQL.BIND_VARIABLE to bind all variables seperately so not to mess with query1) What is the error you get?
2) If you use bind variables inside a query, you should prefix them with colons, so use :l_cur_year_from etc.
3) Why are you using dbms_sql instead of native dynamic sql and/or ref-cursors?

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.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

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.

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.

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

UNION ALL
SELECT 'clm4', 'contract2',10

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.

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?

Creating a complex query in CR designer
I'm running Crystal Reports XI Release 2 on Windows NT. I have a very complex query and cannot figure out how to make it work in CR. Basically, I've got a table A with fields containing reference codes that may or may not be present. I created a SQL query that imbeds select statements in the select fields (the field names between SELECT and FROM). So, it would read something like SELECT field1, field2, (select Code_Name from REF_Table where REF_Table.code=TableA.code and TableA.code is not null) FROM TableA. That works great in SQL Developer.
In CR, I tried a command field but that produces a cartesian set where I get a line for every record that has the field for each and every record in TableA. No good. I just want the name for the value in the TableA record translated to the name if it is present. Is there a way to do this in CR? I used to be able to edit the SQL directly in CR but now it won't let me do that. Anyone know a better way to solve this kind of problem?I'm not an Oracle guy so I don't know what you can or can't do in PL SQL.
I'm surprised that you are getting different results between SQL Developer and the CR Command. CR should pass the query, exactly as it's written back to the server, same as SQL Dev.
IN T-SQL...If you want to make sure that the sub-query is returning only 1 row, try placing "TOP 1" behind the SELECT.
(select top 1 loc.location_name
from ref_location loc
where loc.location_num=obd.location_num and odb.location_num is not null)
I'm thinking that Oracle doesn't have the the TOP N option but it does have a rownum feature. So maybe...
(SELECT x.location_name
FROM (
select loc.location_name
from ref_location loc
where loc.location_num=obd.location_num and odb.location_num is not null) x
WHERE rownum = 1
ORDER BY rownum)
This is assuming that Oracle allows you to use ORDER BY in a sub-query. T-SQL only allows it if it's used in conjunction with TOP N...
Just a thought,

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

Is it impossible at all to create a materialized view using a complex query (i.e. joins + union)?
Thanks in advance
FabioOkay, childishness aside, it is possible to create materialized views using joins, unions and sub-queries. However, these sorts of complex materialized views have limited refresh options.

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.

Complex Query using findUsers()
I have not run across any posting where the findUsers() or findUsersFiltered() methods were doing anything other than a simple query. Is it possible to do a complex query? For instance, find all users whose status is NOT Deleted. Or all users with a date attribute that is before a given date. Or all users with an attribute value of 'X' OR 'Y'. These are simple SQL queries. I can see how to do a series of simple queries and deal with merging or filtering the results. But wouldn't it be way more efficient to do it in the original query?
If it is possible, can you point me to an example?
Thanks,
