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...

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.
BillHi 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 !!!!!!!!!

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

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

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 SarafIt 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,

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.

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,
JacobHi
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

*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 ?

Nishuv. -
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
DivyaHi 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 ESM_EMP_CODE = vemp
and ESM_EFF_DATE <= vdate
Order by ESM_EFF_DATE desc,Esm_Default desc)
Where rownum=1 ;Whats wrong? -
I am trying building a ConstituencyMap of electoral
Constituencies each of which a couple of polling stations. I want
to output information containing the Name and Region of each
constituency and also a running total of the votes from each
polling station in that constituency until all polling stations in
that constituency have reported their results. Further more I will
use a query to find out which party won and change the color of the
cell to the parties assigned color.
My question is how do I get all this information in a single
cell. I do not know if I can use multiple query values in the same
logic. For example, my code to show the constituency name and
region is as attached. Being a novice in databases, I would rather
use multiple queries and try to add the results to the cell, but I
do not know if this is possible, I think a single query drawing
information from my multiple table would be the way to go, but this
would be a complex query.
I will appreciate any insight into this. ThanksAs well as Dan's suggestion for "Teach Yourself SQL in 10
Minutes" by
Ben Forta.
You can reference multiple queries. You just have to
reference the
record set data structure yourself, rather then relying on a
shortcut
such as <cfoutput query="aQuery">
A fully qualified record set reference is
queryName.columnName[row] OR
queryName['columnName'][row].
I.E.
<cfquery name="aQry".../>
<cfquery name="bQry".../>
<cfoutput>
#aQry.aColumn[1]# <---> #bQry['bColumn][2]
</cfoutput> -
Is it possible to show single dimension of measure value in Chart
Hi all,
By using BICS connection(BW-Bex Query), developed Application(dashboard) through sap design Studio 1.2 sp01. My requirement is Measure is Purchase OrderValue, and dimensions are x,y,z, and P. When Open application it has to show X-of Purchase Order values in one Chart,Y-of Purchase Order Value in another chart..like we need to show X,Y,Z and P values in different chart. How we can achieve by using single data source.
Thanks
RamHi Tammy,
Thanks for your quick reply. You are right.. we can create multiple views to show separately. but due to performance issue..is it possible to use single view to finish my requirement?
Explanation: i have 4 charts
1 chart: In X-Axis need's to show X-Values and in Y-Axis need's to show PO value
2 chart: In X-Axis need's to show Y-Values and in Y-Axis need's to show PO value
3 chart: In X-Axis need's to show Z-Values and in Y-Axis need's to show PO value
4 chart: In X-Axis need's to show P-Values and in Y-Axis need's to show PO value
here X,Y,Z,P are dimensions(fields).
unable to add image..
Thanks

Query Design Strategies - servicing multiple reports from a single query
I was wondering if anyone knew of any good web resrouces (articles and such) to assist with Query Design Strategies. What I am specifically looking to do is replace multiple reports from the previous system with just views of a single query. So I was looking at grouping the existing reports that we are replacing into queries and creating views for each report.
The catch is that we will only be utilizing web reporting for report distribution, so we need to:
1. Use views as DataProviders to web templates
2. Broadcast views to users as links where they can see that particular view
Is this possible and does anyone have some info on how to do this?Lets say that 10 broadcasted reports all could use the same query but each in a different navigational state.
1. Can you navigate the query and save as a view and then set up a brodacast rule for that view?
2. Can a DataProvider in a web template be a view?
3. Can the BI Launcher iView take a view name in place of a query?

Update or select in a single query
Hi , I want to select or update from a single query. Can I do that ?
I tried Merge into, but it is for Update or Insert.
Can anyone help me please. I do not want to use stored Proc/function.userPrasad wrote:
I want to fire a update or merge statement inside a select SQL. Is there any way to do that ?Just to clarify:
It is possible to UPDATE based on a SELECT condition within SQL, i.e.,
UPDATE table1 t1
SET col1 = new_val
WHERE col2 IN (
SELECT col2
FROM table2 t2
WHERE t1.col1 = t2.col1
AND col1 = old_val);or to MERGE:
MERGE into table1 t1
USING (SELECT * FROM table2) t2
ON (t1.col1 = t2.col1)
WHEN MATCHED...
WHEN NOT MATCHED...Both of those will use a SELECT, and MERGE can UPDATE, INSERT, both or either one, or none.
