Query writing

please help with a query that joins at least four tables together
Thanks
Tokunbo

Please provide more information, such as the table layouts and what ties them together.
for example:
DESC EMP
Name     Null?    Type
ENAME             VARCHAR2(20)
EMPNO             NUMBER
MGR               NUMBER
JOB               VARCHAR2(20)
DEPT_NO           NUMBER
DESC DEPT
Name          Null?    Type
DEPT_NO                NUMBER
DEPT_NAME              VARCHAR2(20)
Here obviously is tie together by dept_no. So a query would be
select d.dept_name, e.ename, e.job
from dept d, emp e
where d.dept_no = e.dept_no
please help with a query that joins at least four tables together
Thanks

Front end query writing.

Hi gurus,
I know about query designer, Bex analyzer, Bex browser and other related topics such as variables, Conditions and exceptions? But i cant understand what's this Front end query writing or Back end data modelling. Will you plz give me detailed description on this topic, how it should be used in real time scenario.
Thanks,
Sameer.

Hi Sameer
If I understand ur question correctly
query designer, Bex analyzer, Bex browser and other related topics such as variables, Conditions and exceptions? all these are for creating queries and used for generating reports. So these come front end side.
And abt Back end data modelling, it is modelling thing we do in Adminstrator work bench(RSA1) i.e creating infoobjects, datatargets etc.,
In real time we will get the data from source system and store it in the data targets and infoobjects we modelled in AWB and then we report on this datatargets.
So this ETL and modelling part becomes back end and Reporting becomes front end.
I think it's clear for u now
Any doubts let me know

Please read the two threads linked to in the FAQ: {message:id=9360003} and post the relevant details they request, so that people can help you better with your issue.
We cannot help if you just say "my query is slow what do I do to fix it" as we cannot see your queries, your data, or any other information we would need to help. If the answer was that simple, it would be built into oracle so that the optimiser would fix it for you.

ORDER BY barcodeis all you need.
If you want the results sorted as below, Then you can use the analytic ROW_NUMBER function:
ORDER BY CASE
                WHEN UPPER (model) IN ('DELL', 'HP')
          THEN ROW_NUMBER () OVER ( PARTITION BY UPPER (model)
                                             ORDER BY      barcode

I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only), and also post the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using (e.g., 11.2.0.2.0).
See the forum FAQ {message:id=9360002}

SQL query writing limit exceeded.

Hi,
My query contains 1700 lines and the report builder query writen provide line maximum line limit is 1615. When i paste the query in SQL area of report builder, Its paste the 1615 lines and remaining lines cutoff.Its provide the facility to type the query but not to paste the query further. According to the Scenario i cant able to create the view.So please tell me how can i handle it.
Thanks.

Does the query really have to be that big?
I suspect a query of that size would be almost impossible to maintain or debug, assuming the performance is ok.
I would suggest that you review the query to see if there are some parts which could be separated out into formula columns, or possibly split the query up - maybe if the report has a number of groups you could break it up that way.
Generally when you hit an issue of this sort it is best to make your code fit the tools rather that the other way round.

Complex query writing.

I have one table for Loan_mst
Below is the data for column name, salary and loan
Here one person can have multiple loan, multiple loan are separted by ,.
Example CAR1, CAR2, HOME1 . There are three loan separated by comma.
name
salary
Loan
robert
1000000
CAR1, CAR2, HOME1
albert
2520000
CAR1, CAR2, HOME2, HOME3
Using query i want to write data like below.
name
salary
New column
robert
1000000
CAR1
robert
1000000
CAR2
robert
1000000
HOME1
albert
2520000
CAR1
albert
2520000
CAR2
albert
2520000
HOME2
albert
2520000
HOME3
Please help me with the sql query.

Why are you storing multiple value in the column LOAN. That not the correct way to design you table. Your table is in violation of 1NF. 1NF states the column value must be atomic.
Said that your requirement can be achieved like this.
SQL> with t

4 select 'robert' name, 1000000 salary, 'CAR1, CAR2, HOME1' loan

Credit Memo and AR Invoice Query

Hi Everyone,
I'm fairly new to query writing and need to write a query that would list all of the credit memos and invoices. I was able to write the following query that pulls just the AR Invoice info. How do I also pull the AR Credit Memo info?
SELECT T0.[CardCode], T0.[DocNum], T0.[DocDate], T1.[Quantity], T1.[ItemCode], T1.[PriceBefDi], T1.[StockPrice] FROM OINV T0 INNER JOIN INV1 T1 ON T0.DocEntry = T1.DocEntry ORDER BY T0.[CardCode], T0.[DocNum]
When using the generator it does not link the tables together in any fashion. I tried to just add the ORIN and RIN1 tables to it (as I can just have them listed below the invoices), but SAP appears to just lock up and I end up closing the application.
I searched the forum as well and found that there is a link between the two and it is:
RIN1.BaseEntry = OINV.DocEntry
and
INV1.TrgetEntry = ORIN.DocEntry
However, when I try to add these joins to the query, it ends up showing a credit memo for every single line, and I know that is not correct. I know there are different types of joins, so perhaps I'm using the wrong join or something?
I appreciate anybody's help.
Thank you,
Amanda

Hi Amanda,
Try this one:
SELECT T0.CardCode, T0.DocNum, T0.DocDate, T1.Quantity, T1.ItemCode, T1.PriceBefDi,
T1.StockPrice FROM OINV T0 INNER JOIN INV1 T1 ON T0.DocEntry = T1.DocEntry
UNION ALL
SELECT T0.CardCode, T0.DocNum, T0.DocDate, T1.Quantity, T1.ItemCode, T1.PriceBefDi,
T1.StockPrice FROM ORIN T0 INNER JOIN RIN1 T1 ON T0.DocEntry = T1.DocEntry
ORDER BY T0.CardCode, T0.DocNum
Thanks,

Using structure in query

How can i use a structure into a query (writing code)? In some documents (SO, PO, etc.), some fields are into a structure. How can i use that field into a query?
Thank you.

Hi Was
You may use it like

Bex3.5 query to Business Objects

Hello experts.
Can anyone tell me on the possibilities of porting the Bex 3.5 queries directly to Business Objects.
This is without upgrading to BI 7.0 queries.
Thanks
Mrinalini

Hi Mrinalini,
I am agree with Shiva for data up gradation in BOE You can use webi. XI 3.1 and SAP BEX .
Best performance optimizations are done on both SAP BW backend on SP5 and on BOXI 3.1 on Service pack 2 Fixpack 2.1.
For Web Intelligence, Crystal Reports) even if you have built them with the Query Designer 3.5. in BEX Query analyzer who support BOE 3.1 , You can use your stuff for best Query writing , design for the same !!

Query generation basic documentation

Dear Friends,
Is there any documentation for query writing.
Ex.
How to use inner join , why?
what is T0 (normally we observed in query)
Syntax and its use.
Overall, i want fundamentals of making query.
Regards,
MAhesh.

Hi,
The document u r looking for might not be available in sap documents but u can better search for sql tutorials.
As far as u asked about T0 , its nothing else but just a alias name used for the first table used in a query.
I.E.
if we want a report using two tables then either we can write
select ordr.docnum,ordr.docdate,rdr1.itemcode from ordr innerjoin Rdr1 on ordr.docentry= rdr1.docentry
or else u can replace ordr with T0 Nd rdr1 with T1
and the query wud look like
Select T0.docnum,T0.docdate,T1.itemcode from ordr T0 innerjoin Rdr1 T1 on T0.DocEntry = T1.DocEntry .
and as u asked about the basic syntax
then a simple query format is
Select columnname from tablename where 'specify ur conditions'
Hope this might be helpful to u .
Thanks

Install Oracle 10g with Toad 9.1

Hi All,
I am a novice in database(SQL,PLSQL) programming and hence want to learn and practise very deeply in detail for which i want to install Oracle 10g client with Toad 9.1.So need your advise on the process.
(a)Do i need to download entire Oracle Enterprise Edition Installation for Vista? I have read in one of the forums that downloading only the Oracle Client is enough?
Can you please advise me?
(b)I already have the TOAD 9.1 setup with me which i can install.But,i do not know that how will i use TOAD interface and connect to the oracle database.
(c)Also,any sample script/database with some tables that i can use for learning complex SQL query writing would be very helpful.In brief-any project that i can work on in building all the requirements by writing SQL which simulates real time scenarios of SQL development.
Please help me ,i am struggling.
Thanks
