Equi join-same output get from subquery??

Hi,
I written one equi-join query, same ouput can i get from sub query??.
select e.empno,e.ename from emp e,dept d
where e.deptno=d.deptno;
Regards,
Venkat.

Really have no idea what you mean.
If you need those d. columns, just add them to your select list.
There's no subquery here at all.

Equi JOINS vs SUBQUERY

May I know the difference in processing time or execution time when we use the Equi-Join and when we use Suquery in Search criteria.
Plz help, because the query (137 query) which we have written contains Subquery and fetching thousands of records, taking processing time 10 min.
We also altered the query batch with Equi-Joins and it is taking only 5 min. So can we say that Equi-Joins are much faster then Subquery.
Do Reply.
Thank in Advance

In theory, it shouldn't matter. If you are able to figure out how to unnest subquery, the optimiser query transformation engine would likely to be able to do that that as well.

From this example it seems i can't :(
Thx
Alex

For what you are trying to do the simplest solution is to have one socket per "stream" that is the way they are designed to be used.
However, you can multiplex multiple stream over a single socket, but you have do the coding yourself or use a solution which does this for you e.g. JMS. (There is no support at the socket level for this)

Same output type getting triggered twice upon saving the document

Dear SDNers,
I have a shipment Document.
Upon saving it the same Output type gets generated twice. ( in a gap of 1 second)
Clarification needed:
1. Please guide as to where i need to look for the error as to why same output is getting triggered twice simultaneously( gap of 1 second).
2. i have checked in the processing routine associated with it. Is it the right place?
P.S. I had posted another similar thread. Closed it since i felt it lacked clarity.
Regards,
SuryaD.

Hi,
Fetch the data from Nast table for that document number
Check the vstat . if it is 0 then use the below function module.
CALL FUNCTION 'RV_MESSAGE_SET_PROCESS_STATE'.
Then it will update the existing single record for the first time .
Next time on wards you will get the multiple records for te document in the Nast table.
For that you need to change the VSTAT status as per the requirement.
Hope this might solve your problem.

Row should be locked before getting an output stream from an attribute

I have table Worker with photo attribute (its database type is ORDSYS.ORDIMAGE, entity attribute type is OrdImageDomain).
I use standard display and edit renderer for displaying and changing ord-image attribute.
If I add new worker and set him photo, everything is OK.
But if I edit some existing worker and set them photo, while posting to database exception is thrown.
This problem began some time ago, after made some changes (like upgrade JDev, changing some AM configuration properties, and so on...), but I ca't reproduce right behaviour.
I use JDeveloper 9.0.3.2, database is Oracle8i Release 8.1.6.0.0, I tried reserved and stateful AM mode both (the same bad result), pesimistic locking.
Error occures inside Tomcat 4.1.27 and OC4J both.
Does anybody know any hint about this error...?
Than you very much
Jan

Thanks for replay.
Yes, I use JDev wizard generated BC4J JSP app (it was generated inside 9.0.2 and then migrated to 9.0.3).
I changed inside it many things, but I thing no important.
I have for example copying record to history while editing, but when I disable it, the same problem occures.
I changed database - 8.1.7 to 9.2.0.2.0, but the same problem.
Any hint?
Thanks for any comment.

How to get multiple html output file from an xml document via xslt?

Thanks for help

Not a standard feature of XSLT. But Michael Kay's XSLT implementation, SAXON, provides that as an extension. Get it here:

How can I get iCal not to show the same birthday dates from my iCloud

How can I get iCal not to show the same birthday dates from my iCloud?

You don't need them stored locally for a backup. You can manually export your contacts as archive for backup. Also, if you are backing up with Time Machine, you already have a backup. If your hard drive crashed, you would have to rely on your backup or iCloud anyway.
So, if you're comfortable with that, sign out of iCloud. Choose to delete contacts from the computer. When you sign back into iCloud, you should only have iCloud contacts listed in AB. When you open iCal, you should only have one listing for birthdays.
The other alternative is to disable the Birthday c.alendar and create one manually.

Question about creating multiple output files from same query

I have a query like this:
select * from emp;
ename empno deptno
Scott 10001 10
Tiger 10002 10
Hanson 10003 20
Jason 10004 30
I need to create multiple output files in xml format for each dept
example:
emp_dept_10.xml
emp_dept_20.xml
emp_dept_30.xml
each file will have the information for employees in different departmemts.
The reason I need to do this is to avoid executing the same query 200 times for generating the same output for different departments. Please let me know if it is practically possible to do this.
Any input is greatly appreciated.
Thanks a lot!!

You can write a shell script to generate the multiple spools files for the same output. Below script may helps you.
#====================
#!/bin/bash
n=0
while [ $n -le 20 ]
do
n=`expr $n + 1`
sqlplus -s system/manager <<EOF
spool emp_dept_$n.xml
select count(1) from tab;
spool off
EOF
done

Invoice Print and Email from same output type

Hi All,
We want to print invoice and send an email to customer. Can this be acheived using same output type??
If yes, plz guide how can we do this..
I check some queries in forums but they had coding etc. Can we do it with config??
Regards,
Satish.

I'm not sure why you wouldn't configure two output types. However, you can do this with one output type in a number of ways:
1. Use a speciial function output (transmission medium 8).
This allows you to write ABAP code to anything you want. However, you have to manage print contols on yur own as the special function transmssion medium doesn't allow you to specify these on he condition record.
2. Change the driver program for the print output for the output to send emails.
You would need to handle the email routing on your own because the output records for print are just for printing.

Get all output-soundsignals from the soundcard

I want to display all output-audiosignals from the soundcard. How can I realize that?
So far I tried that with the Java Sound API and the following code:
audioFormat = getAudioFormat();
dataLineInfo = new DataLine.Info(TargetDataLine.class, audioFormat);
targetLine = (TargetDataLine) AudioSystem.getLine(dataLineInfo);
targetLine.open(audioFormat);
targetLine.start();
targetLine.read(dataBuffer, 0, numOfBytes);
private static AudioFormat getAudioFormat(){
float sampleRate = 8000.0F;
int sampleSizeInBits = 16;
int channels = 1;
boolean signed = true;
boolean bigEndian = false;
return new AudioFormat(sampleRate, sampleSizeInBits, channels, signed, bigEndian);
With that I got different results on different computers. Sometimes it displays data
although there isn't any output on my soundcard and on some other computers it displays nothing.
I've already read a lot of tutorials, but they didn't help me.
Thank you.

Help needed on Equi join?

I have 3 views and in that common column datatype is varchar. I have to use equi join to get the data from 3 view.
In 3 views total records are 23668,111,3033
when i wrote the join i am getting the output in lakhs. I don't whether the output is right or not.
Please guide me on this.
Waiting for valuable replies.
Thanks and Regards
Sridhar.

If you're returning more rows than you expect, it means that you have 1 to many or even many to many join.
I would re-write your query this way:
SELECT p.facid, rxs.rxno, rxs.rxbatch,patlname,patfname,InitReview,LabelPrintedOn,packed,PlacedInTote,street1,zip,BatchDescr
FROM Patients p
INNER JOIN rX.dbo.rxs rxs
ON p.facid = rxs.FacID
INNER JOIN rX.dbo.RxBatches Batch
ON p.facid= Batch.FacID
WHERE p.facid in('CRH','LSRX') and Batch.batchdescr LIKE 'STAT%'
I also suggest to add alias to every column in your query. Even if the column belongs to a particular table, adding the alias in front of it will make maintenance of this query much easier. Say, I have no idea if BatchDescr field belongs to the second table
RxBatches or rxS, so I made a guess.

Equi join as well as outer join

Hi all,
I have two table. They have common fields case_id and issuer_id.
I want to retrieve the data from two tables first based on case_id(equi join) and then issuer_id(outer join). The query like this
select t1.case_id,t1.case_name,t2.issuer_name from case t1,issuers t2
where t1.case_id=t2.case_id and t1.issuer_id=t2.issuer_id(+)
The above query displays error
so, My query first gets the data based on equijoin , then i want to apply outer join on that same tables.
plz try to solve the above problem

SQL> create table mycase
2 as
3 select 1 case_id, 'NAME1' case_name, 1 issuer_id from dual union all
4 select 2, 'NAME2', 2 from dual union all
5 select 3, 'NAME3', 3 from dual union all
6 select 4, 'NAME3', 4 from dual
7 /

SQL> create table issuers
2 as
3 select 1 case_id, 1 issuer_id, 'ISSUER1' issuer_name from dual union all
4 select 2, 3, 'ISSUER2' from dual union all
5 select 3, 4, 'ISSUER3' from dual union all
6 select 4, 6, 'ISSUER4' from dual
7 /
Tabel is aangemaakt.
SQL> select t1.case_id,t1.case_name,t2.issuer_name from mycase t1,issuers t2
2 where t1.case_id=t2.case_id and t1.issuer_id=t2.issuer_id(+)
3 /
                               CASE_ID CASE_ ISSUER_
                                     1 NAME1 ISSUER1
1 rij is geselecteerd.The above query doesn't make sense: the outer join predicate says "if I don't find a matching issuer_id, Oracle please make up an entire null issuer record for this one". Then the other predicate says "t1.case_id=t2.case_id" where a null value for t2.case_id will never match t1.case_id and will be excluded from the result set. Effectively you could drop the plus sign in this query to achieve the same result.
Maybe you want the query below?
SQL> select t1.case_id
2       , t1.case_name
3       , case t1.issuer_id
4         when t2.issuer_id then t2.issuer_name
5         else null
6         end issuer_name
7    from mycase t1
8       , issuers t2
9   where t1.case_id = t2.case_id
10 /
                               CASE_ID CASE_ ISSUER_
                                     1 NAME1 ISSUER1
                                     2 NAME2
                                     3 NAME3
                                     4 NAME3
4 rijen zijn geselecteerd.Regards,
Rob.
