Is this possible in a single query?????

While I don't think this is possible in a single query, I definately don't have the background the experts here have.
I have a request to identify all shipments in a period/range of periods that have a payment transaction. For those shipments, the user wants a list of all payment transactions and the initial accrual entry listed by period for potentially a large range of periods. The accrual and payment entries are identifed by the same characteristic and a 0Amount key figure contains the values. A couple methods I have tried I have listed in previous threads with either errors or the query blowing up with what appears to be a cartesian product issue.
Anyone done something like this who can provide pointers.
Bill

Hi Bill,
Why dont u use RRI-report to report interface for this Requierment ??
There are lots of threads on RRI ,just follow them and u can satisfy this requirement.
1)Query A for Shipments
2)Query B for Payment Transactions.
Call report B from Report A
1)GOTO RSBBS
2)Create New
3)Sender Query Give the First Query Report A
4)Below sender Query there is Receiver Query  give the RRI query report B (The query which u want to call).Report type should be BEX ,and Target system--Assign the System(Local) and in the report give the Report B.
5)In the Report A check whether in the GOTO -u get the Receiver Query ,i.e Report B.
Hope this help !!!!!!!!!

Possible in a single query ...?

We have one question master table as...
questionnumber number(3),
answer char(1)
And another table candidate_choice table as...
candidatesrno number(6),
questionnumber number(3),
answer char(1),
marks number(5,2)
Candidate entries are stored in candidate_choice table. Now we have to prepare marks sheet. For this we need to compare each candidate's answer with question master table and it it matches, we have to give 1 mark. And if it does not match we have to give -1 marks. And total marks is to be stored in marks column of candidate_choice table.
How can we write single SQL query to do this ?
(we are using Oracle 9i R. 2)
Thanks,
Kiran Shah.

Nice point Kamal. I forget to give one Candidate master table details.
So actually is goes like this...(with little modification in Candidate_choice table)
Table : Candidate master
create table jacademy(
candidatesrno number(6),
name varchar2(100),
Marks number(5,2))
Values
insert into jacademy values(1, 'Kiran Shah', NULL)
insert into jacademy values(2, 'Ramesh Mande', NULL)
insert into jacademy values(3, 'Saseendran', NULL)
question master table as...
create table qmaster(
questionnumber number(3),
answer char(1))
values
insert into qmaster values(1, 'T')
insert into qmaster values(2, 'F')
insert into qmaster values(3, 'T')
And another table candidate_choice table as...
create table candidate_choice(
candidatesrno number(6),
questionnumber number(3),
answer char(1))
values
insert into candidate_choice values(1,1,'T')
insert into candidate_choice values(1,2,'T')
insert into candidate_choice values(1,3,'F')
Now we have to prepare marks sheet. For this we need to compare each candidate's answer with question master table and it it matches, we have to give 1 mark. And if it does not match we have to give -1 marks. And total marks is to be stored in marks column of candidate master table.
Thanks...

Getting result with single query

Hi,
I'm using db 10.2.0.1.0
I have a table emp_shift , with data like below
EmpCode           Shift     Effdate            Default
1                 SHFT1    02-jan-2012          N
1                 SHFT2    04-jan-2012          Y
1                 SHFT3    04-jan-2012          NSo if user inputs EmpCode and Effdate, based on that i've to take the latest record, with default = 'Y' (if any) else default 'N'
Suppose
Case 1 : Input Empcode:1 Date:10-jan-2012
Then i should get the below record
1                 SHFT2    04-jan-2012          YCase 2 : Input Empcode:1 Date:03-jan-2012
Then i should get the below record
1                 SHFT1    02-jan-2012          NI want this result with a single query, is this possible?
Thanks

Hi Thank you both,
I'm trying this process through forms. and my forms version is 6i.
There where i'm trying the query with the cursor, i'm getting error
Encountered the symbol Order when expecting one of the following
.()...and my cursor is
Cursor cur_shft(vemp Varchar2,vdate Varchar2) is Select ESM_SHIFT_TYPE
     from (Select ESM_SHIFT_TYPE from EMPLOYEE_SHIFT_MASTER

               Where rownum=1 ;Whats wrong?

Is a single Query possible for this?

Hi everyone,
I have a requirement to get a list of 10 free (non-assigned) ids from a table. The ids range from say 1-32000. The table contains only the assigned ids. So the idea is - if say we have 15 records already in this table like 2,7,23,4,65,22,665... etc (random, non-repeated, unsorted values), then I need to get the first 10 numbers in the range 1-32000 which are not there in the table e.g. 1,3,4,5,6,8,...etc. One idea is to have a table2 with a single column having values 1-32000 i.e. 32000 rows. Then we can give the query like -
select col1 from table2 where rownum<=10 and col1 not in (select id from table1);
Is there a better way to get this output without having a separate table with 32000 rows? Or, is it possible to form a faster query even with the proposed solution?
Thanks,
Regards

Sanchayan,
Your problem can be solved by a single query.
Try the following query:
(THIS WILL GIVE AN IDEA")
select * from (
select rownum from (select numero from srm_test)
minus
select numero from srm_test)
where rownum < 10
order by 1
YOU WILL GET:
ROWNUM
1
3
6
8
10
11
12
7 rows selected.
The contents of srm_test are:
2, 7, 23, 4, 65, 22, 665, 90, 87, 200, 9, 5
null

Can this be done by just a single query alone ?

hi ,
I have the following data
id , type1 , duration, status
1 a 2 R
1 a 3 R
1 a 2 I
i need to become a single record as follows
id , type total , total_R , total I
1 a 7 4 2
partitition by does not allow where clause
besides 1st creating a table and then update the fields , is this possible in just using 1 query (besides unioning several query for total_R , total_I) ?
pls advise
tks & rgds

select id , case when type like '%I' then sum(time1)
end case total_1
group by id , -- if i do not speciy type it won't
work but what i want is a total over each different
idpls adviseSum should come outside the case statment. Try this
select id , sum(case when type like '%I' then time1 end) total_1
group by id There is no performance difference between case and decode.

I need to generate a still shot from from a video. I would like to accomplish this task using a single application. If this is not possible with my MacBook Pro as purchased from Apple, please recommend which applications I can purchase.

I need to generate a still shot from from a video I made with my camera. I would like to accomplish this task using a single application. If this is not possible with my MacBook Pro as purchased from Apple, please recommend which applications I can purchase that include this feature. Thanks in advance.

For FREE do the following:
When you get to othe part of the video you want a still shot from, put the video on pause.
Take a screen shot: Apple>Shift>4 - which will produce a cross hair so you can manually select which part of the video you want.Check inside either your Applications or Utility folder for an app called Grab. Will do the above with just a single click.
If you still want to purchase software, suggest that you do a Google & MacUpdate search. This way, you can find exactly what you want.

Is it possible to combine 2 different reports in a single Query?

Dear All,
What am I working at?
I produced a Query for Debtors Aged Analysis which mimics the Official SAP B1 8.8 Aging Report.
It ages the outstanding invoices by Posting Date ( RefDate in JDT1)
I also made another Report which ages outstanding amounts by Document Date simply by replacing all RefDate by TaxDate
They give different answers if Posting Date is different from Document Date, e.g a manual invoice dated 5 Jun 2011 is posted on 2 Jul 2011.
What I want to do?
My idea is to produce a SINGLE QUERY which will generate either Aging depending on settings:
    (a) A Debtors Aging by Posting Date
    (b) A Debtors Aging by Document Date
I declare 2 variables:
(a) @refdt is [%1] and represents Posting Date (JDT1 RefDate)
(b) @taxdt is [%2] and represents Document Date (JDT1 TaxDate)
When the Query is run, the foll dialog appears:
Query - Selection Criteria
Posting Date             Equal .......
Document Date            Equal .......
OK   Cancel
We are expected to fill in only 1 date and leave the other blank, and Query will generate the required report .
What is my problem?
Query runs smoothly, but amounts in the Balance column does not get analyzed in the Age brackets: Current / 1 Mth Ago / etc
I think I know where's the problem
I am assuming (wrongly) that if we don't fill one date field, the query returns NULL for that variable. In fact, it appears to return GetDate().
Help
Can anybody help me put the correct commands so that all my balances are correctly analysed in the respective age buckets?
Thanks

01-aug-09 | 112 | 1 | 2000
01-aug-09 | 113 | 2 | 900
01-aug-09 | 114 | 3 | 1250

If customer’s balance is increased from last month then mark as ‘Augment’
If customer’s balance is same as last month then mark as ‘Maintain’
If customer’s balance is decreased from last month then mark as ‘Diminish’
Else ‘Left’

Multiple databases in a single query

I need to query multiple databases in a single query.
e.g.
Database d1 contains table t1 with column id
Database d2 contains table t2 with column id
I need a query like
SELECT * FROM t1, t2 WHERE t1.id = t2.id;
is this possible in jdbc? if yes can anyone help with some sample code?
thanks,
Ashish Saraf

It is not possible using the JDBC API to query tables in two or more databases using a single query. The reason is that a JDBC Connection is made to a single data source.
However, some databases support the idea of federations or linked tables. What you do is inside the database manager link or federate a table that is present in another DBMS. Then, pose a single JDBC query to the one DBMS which will have its own table and links to the external tables.
Another approach is to use a special JDBC driver with a built-in integration engine that will perform a query across multiple databases. In effect, the system poses separate queries to the different databases and integrates and joins the data together for you automatically on the client-side. That is much easier than doing it yourself in code, but that is also possible for simple queries.
As part of my research program, we have released a shareware version of the UnityJDBC driver that can query multiple databases using a single SQL query. For more information, see:

All selected 'n' consecutive rows in retrieved in a single query

hello,
I have table T with 50,000 rows
create table T
(student_id number,
class_id number,
quiz_id number,
marks number)
some sample rows like
INSERT INTO T VALUES (1,1, 1, 50);
INSERT INTO T VALUES (2,2, 2, 40);
INSERT INTO T VALUES (3,1, 3, 34);
INSERT INTO T VALUES (1,1, 4, 10);
INSERT INTO T VALUES (1,1, 5, 30);
INSERT INTO T VALUES (1,1, 6, 29);
INSERT INTO T VALUES (3,2, 7, 34);
INSERT INTO T VALUES (3,2, 8, 33);
INSERT INTO T VALUES (3,2, 9, 56);
INSERT INTO T VALUES (1,1, 7, 90);
INSERT INTO T VALUES (2,2, 8, 0,);
INSERT INTO T VALUES (1,1, 8, 80);
INSERT INTO T VALUES (2,2, 8, 65);
INSERT INTO T VALUES (1,1, 9, 34);
INSERT INTO T VALUES (2,2, 9, 11);each student belongs to one class_id. each student participates in many quizes. each quiz has its unique id. each student can appear once in a quiz_id
I am doing the below analysis and query:
1. with below query I am finding which student_id had most marks in any 3 successive quizes (see the 3-1 part below) in the query..
SELECT QUIZ_ID,
      STUDENT_ID,
SUM (MARKS) OVER (PARTITION BY STUDENT_ID ORDER BY QUIZ_ID1
RANGE BETWEEN CURRENT ROW AND (3-1) FOLLOWING) consecMARKS , MARKS   FROM
      (SELECT QUIZ_ID,
        STUDENT_ID,
        MARKS,
      ROW_NUMBER() OVER (PARTITION BY STUDENT_ID ORDER BY T.QUIZ_ID) QUIZ_ID1
      FROM T
      WHERE MARKS IS NOT NULL
      ORDER BY 1
    ORDER BY 3 DESC

         9          2          11
15 rows selected.With above query, I can play around and find for any 'n' number of consecutive quizes, like marks in 2 consecutives quizes, 3, 4 and so on but for each 'n' value I've to run a seperate query mentioning (2-1) or (3-1) or (4-1) and so on..
since my table is big and there are about 400 quizes so what I want to find out is for each 'n' consecutive quiz (from 1 to 400) which student had most marks for each consecutie 'n' quiz. Like in 1 (consecutive) quiz which student had the highest marks and then 2 conseuctive quiz who had most marks and then in 3 consecutive quiz who had most marks and so on till 400 consecutive quiz who had most marks... rather than running query for each 'n' value seperately i want a single query that can give me a summary of most marks in each n consecutive quizes...
my sample output is:
Nth consecutive quiz     student_id    sum(marks)
1                        1              90
2                        1              170
3                        1              246
4
100
200
300
400                      ?              ?   Is this possible to get the above output from one single query? If there are two or more students with equal most marks for any 'n' conseutive quizes then both should come in the summary.
Hope I have been able to put up my question clearly.

Ramis

How to calculate the area of a large number of polygons in a single query

Hi forum
Is it possible to calculate the area of a large number of polygons in a single query using a combination of SDO_AGGR_UNION and SDO_AREA? So far, I have tried doing something similar to this:
select sdo_geom.sdo_area((
select sdo_aggr_union (   sdoaggrtype(mg.geoloc, 0.005))
from mapv_gravsted_00182 mg
where mg.dblink = 521 or mg.dblink = 94 or mg.dblink = 38 <many many more....>),
0.0005) calc_area from dualThe table MAPV_GRAVSTED_00182 contains 2 fields - geoloc (SDO_GEOMETRY) and dblink (Id field) needed for querying specific polygons.
As far as I can see, I need to first somehow get a single SDO_GEOMETRY object and use this as input for the SDO_AREA function. But I'm not 100% sure, that I'm doing this the right way. This query is very inefficient, and sometimes fails with strange errors like "No more data to read from socket" when executed from SQL Developer. I even tried with the latest JDBC driver from Oracle without much difference.
Would a better approach be to write some kind of stored procedure, that adds up all the single geometries by adding each call to SDO_AREA on each single geometry object - or what is the best approach?
Any advice would be appreciated.
Thanks in advance,
Jacob

Hi
I am now trying to update all my spatial table with SRID's. To do this, I try to drop the spatial index first to recreate it after the update. But for a lot of tables I can't drop the spatial index. Whenever I try to DROP INDEX <spatial index name>, I get this error - anyone know what this means?
Thanks,
Jacob
Error starting at line 2 in command:
drop index BSSYS.STIER_00182_SX
Error report:
SQL Error: ORA-29856: error occurred in the execution of ODCIINDEXDROP routine
ORA-13249: Error in Spatial index: cannot drop sequence BSSYS.MDRS_1424B$
ORA-13249: Stmt-Execute Failure: DROP SEQUENCE BSSYS.MDRS_1424B$

ORA-06512: at "MDSYS.SDO_INDEX_METHOD_10I", line 27
29856. 00000 - "error occurred in the execution of ODCIINDEXDROP routine"
*Cause:    Failed to successfully execute the ODCIIndexDrop routine.
*Action:   Check to see if the routine has been coded correctly.
Edit - just found the answer for this in MetaLink note 241003.1. Apparently there is some internal problem when dropping spatial indexes, some objects gets dropped that shouldn't be. Solution is to manually create the sequence it complains it can't drop, then it works... Weird error.

Can we show 2 queries in a single query ?

Hi experts,
We require an output of a bex query.
But the output is coming in two different queries.
Is it possible to show two queries in a single query ?
Regards,
Nishuv.

Hi Praveen,
We are using bex 3.x. I opened a workbook. in the view toolbar->Toolbars->Control Toolbox.
I clicked on this. A tool box came in the right side of the sheet.
The options which we got here are:
Exit Design mode
Properties
View code
Check box
Text box
Command button
Option button
List box
Combo box
Toogle button spin button
Scrool bar
Label
Image
More controls
Tool bar options.
Here i am not able to see the Analysis grid.
Is there anything more to be done to get this ?
Regards,
Nishuv.

Is this possible in a single query?????
