Can I return a record/table of records of proceedings aside Java Server?
I need to get data from a remote service during the execution of a PL/SQL procedure. The first of these calls returns a table, each entry that consists of a number of channels, but the second Gets a master-detail structure, a parent row, and an arbitrary number of records of invoice line.Just to make it interesting the PL/SQL must operate on an existing 8i database, which means that I have to encode any Java JDK 1.1.8 (which should be about 1990 vintage).
The natural way to do this would be to code a java procedure that return an array of records. Unfortunately, I understand that you cannot return a record of PL/SQL returned by a call to jdbc, which suggests that there may be no class in Java or Jave to manage server-side. There is certainly no record type in oracle.sql. *;
Is it possible to return a record or a table of records or as a return value or OUT of a java PL/SQL function procedure parameter and, if not, what is the best way to return data that can be structured in the PL/SQL code?
Oracle 8i shouldn't be so bad - you should still have nested table types, and the ability to use a collection in a select... TABLE... MOUNT the statement and return a refcursor, for example - without doubt the best way to return a set of information from a java client.
However, you can map collections of Oracle to Java arrays using oracle.sql.STRUCT, oracle.sql.ARRAY, oracle.sql.StructDescriptor and oracle.sql.ArrayDescriptor - are they available in the JDK?
Oracle 8.1.7 documentation is always available online:

Can I return a video project 4.0 after I recorded in 9.0?
I need to recover several 4.0 video projects I recorded to 9.0. They will not open in 4.0 now. Can I return them to 4.0?
Nope. It's one of the reasons why I recommend to my books NEVER open an old project of version with a new version of the program. (Cela and the fact that it tends to corrupt the old version of the project and cause a behavior bug.)

HelloI have a requirement of the company, where I need to return a record type (OUT parameter) for environment call based on the given input value.
Suppose that if the value is correct and corresponding record is found in the table then the return values for this key entry. If matching record is found, then return the exception to the calling environment.
To do this, I created an example of test table and populated records.
create table plch_test(dept_id number,dept_name varchar2(50),cost_centre number); insert into plch_test values(10,'SALES',1010); insert into plch_test values(20,'FINANCE',2010); insert into plch_test values(30,'MKTG',3010); SQL> select * from plch_test; DEPT_ID DEPT_NAME COST_CENTRE ---------- -------------------------------------------------- ----------- 10 SALES 1010 20 FINANCE 2010 30 MKTG 3010
I wrote a simple block and gave a valid key dept_id (10 in this case) to display costcentre for this dept_id and dept_name I said tow types of records, one for valid record and another exception
SQL> DECLARE 2 TYPE rec_dept IS RECORD(dept_name varchar2(50),cc number); 3 l_rec_dept rec_dept; 4 TYPE rec_exception IS RECORD(err_code number,error_message varchar2(300)); 5 l_rec_exception rec_exception; 6 BEGIN 7 SELECT dept_name,cost_centre 8 INTO l_rec_dept 9 FROM plch_test 10 where dept_id=10; 11 dbms_output.put_line('DEPT_NAME'||' '||l_rec_dept.dept_name||' '||'COSTCENTRE'||' '||l_rec_dept.cc); 12 EXCEPTION WHEN NO_DATA_FOUND THEN 13 l_rec_exception.err_code:=sqlcode; 14 l_rec_exception.error_message:=sqlerrm; 15 dbms_output.put_line(l_rec_exception.err_code||' '||l_rec_exception.error_message); 16 END; 17 . SQL> / DEPT_NAME SALES COSTCENTRE 1010 PL/SQL procedure successfully completed. SQL>
Now for invalid dept_id and expose the message by using exception record type I stated.
SQL> ed Wrote file afiedt.buf 1 DECLARE 2 TYPE rec_dept IS RECORD(dept_name varchar2(50),cc number); 3 l_rec_dept rec_dept; 4 TYPE rec_exception IS RECORD(err_code number,error_message varchar2(300)); 5 l_rec_exception rec_exception; 6 BEGIN 7 SELECT dept_name,cost_centre 8 INTO l_rec_dept 9 FROM plch_test 10 where dept_id=40; --Invalid --data is not present 11 dbms_output.put_line('DEPT_NAME'||' '||l_rec_dept.dept_name||' '||'COSTCENTRE'||' '||l_rec_dept.cc); 12 EXCEPTION WHEN NO_DATA_FOUND THEN 13 l_rec_exception.err_code:=sqlcode; 14 l_rec_exception.error_message:=sqlerrm; 15 dbms_output.put_line(l_rec_exception.err_code||' '||l_rec_exception.error_message); 16* END; SQL> / 100 ORA-01403: no data found PL/SQL procedure successfully completed.
Now as you can see I need to include this point in a procedure with an input parameter and output must be a record types which will return
rec_dept if it becomes a key input valid or an exception if she meets a key not valid.
CREATE PROCEDURE test_prc IS(p_in_dept_id IN plch_test.dept_id,p_output ?????? DECLARE TYPE rec_dept IS RECORD(dept_name varchar2(50),cc number); l_rec_dept rec_dept; TYPE rec_exception IS RECORD(err_code number,error_message varchar2(300)); l_rec_exception rec_exception; BEGIN BEGIN SELECT dept_name,cost_centre INTO l_rec_dept FROM plch_test where dept_id=p_ind_dept_id; RETURN l_rec_dept; EXCEPTION WHEN NO_DATA_FOUND THEN l_rec_exception.err_code:=sqlcode; l_rec_exception.error_message:=sqlerrm; RETURN l_rec_exception; END; dbms_output.put_line('DEPT_NAME'||' '||l_rec_dept.dept_name||' '||'COSTCENTRE'||' '||l_rec_dept.cc); END;
Hope that the explanation above help in imposes the requirement

Return a record which can mean two things is complicated; I'm not an experienced myself pl/sql developer, but this looks like a craft.
The idea of exceptions under Sir Thomas of Kyte, is that any treatment must be stopped; You should RAISE an exception to the appellant so that he can figure out what to do with it. What you are saying, this is an exception, but is not a little, cos it's okay, I'll just keep but I will go back to the appellant in any way, but the appellant shall include this registration type is - would it be a record representing a row of the table, or it might be an exception... yuck.
(a) is it really an exception
(b) what do you do with it? You he could log into a table, you could write to a file, you can display an error message on the screen
But really, it's weird to want to pass an exception as return value.
These are all considerations of design, not really anything to do with the pl/sql language in itself.
But hard, if you send a record type a successful being found, registration-based stick to it and don't use it to return a record; do not try to do double duty with her flipping something else. Just save the message put in a table, or print it to the console, or what you want to do with; but as I said, the most important decision is, is this really an exception. And is based on the data model and the expectations of cleanliness of the data etc.
Think about how you call built-in functions. If you send garbage to a built-in function it does not return successfully, leaving you to figure out whether he succeeded or not by inspecting the return value; It goes kaboom, something bad happened. That's what your function should do if something bad happens, that is to say, if you get an exception, it should probably go kaboom.

fusion of the fields to return 1 record instead of 2 or more
Hi all
New here and maybe above novice in SQL statements, but it's escape me if its even possible.
The problem is that I have tables in the main table is unique id'd records and not dupes, table 2 contains the unique id of 1, but can contain multiple because some areas are the entry like one to multiple and stored values in the form of 2 folders. What I need to be able to do is to shoot that these records back out as 1 Plug and not multiple. Example as follows:
Int table1 ID (INT PK SINGLE) Field1, Field2 int - theres only one ton more fields but not necessary to even put them here
Table2 ID INT, int Field1, Field2 int - once again a ton more is not necessary
Table1:
ID Field1 Field2
1 2 5
2 5 5
Table2
ID Field1 Field2
1 1 3
1-3-3
2-1-1
2-3-1
2 1 2
And so when I do a select and do a left outer join on the ID I'm would get returned 2 records for ID 1 and ID 2 3 records.
Any ideas on how to merge the 2fields Table Select to return only records?
Thank you
StanHi, Stan,
Welcome to the forum!
If you want a row of output for each id. What do you want on this line? After the correct output, want to get sample data you have already posted.
This site normally compresses white space, so if you want to post something when the columns are well aligned, and then type the 6 characters:
{code}
(small letters only, inside curly braces) before and after the section of text formatted to preserve spacing.
You can ask on the aggregation of the string, in which case [this page | http://www.oracle-base.com/articles/10g/StringAggregationTechniques.php] will be helpful.

Can I make a record on the Air of MacMook, etc.. ?
In our master class, we use "Collaborate" for audio visual. Here is a somewhat convoluted series of question for which I couldn't find an answer online.
1. can I I dictate a recording on MacBook Air? When I try to play the record AND dictate, there is no sound. That is, it seems that I can have one or the other, but not both.
2. just behind that, can I make a voice memo to my iPhone? I know that it will be on my MacBook but I encounter the same problem. Is there an "end-around" that would allow me to do this?
3. is there a software that would allow me to do this?
4. is there a way that I could use a splitter microphone cable that allow me to do that?
5. Finally, if I have a 3.5 male cable, it would allow me to dictate (or save) from the iPhone directly on the MacBook Air.
Any help on this maze would be a great help. Also, I'm techno-challenged so a process step by step would also be useful.
Thank you!
I suggest you section in the Apple local store for a discussion with one of the geniuses.
I guess this app is the Blackboard application work?
1: Yes, OS X can record audio. GarageBand from Apple iLife app is commonly used for this and can be effective to record audio and to overlay additional tracks on audio existing. Better get a mic if you can manage that, the microphone has a terrible audio quality. The people of Blue Microphone products with good reputation, as do AudioTechnica and other sellers...
1a: simultaneous record and playback means that you pick up playback during recording if you're not careful. Which means a helmet or another mechanism to keep the isolated audio tracks or a directional microphone with noise cancellation. Headphones are probably preferable here, too. Mikes can and do pick up all kinds of noise, even the most accomplished.
2: Yes, there is an audio recorder app on iOS.
2a: same problem as 1 a - you need to separate the channels to the inputs and outputs.
3: See what GarageBand can do - but it is the registration center and not collaboration - and maybe the products proposed by Rogue Amoeba or Audacity.
4: again, you must separate channels of input and output (and headset), or you get the audio output in return via the input channel.
5: I think technically possible, but you will get the output on the input and sound from the microphone of the iPhone is not very good either.
To save a collaboration and not the typical rather more static recording with GarageBand, the various applications that are people doing podcasting are probably in the arena just for your needs here, especially if they can - as different packages can do, either directly or through the products of Rogue Amoeba - audio capture from several sources. Several people use these tools for audio Messages (for example) or Skype capture of several participants, as part of the capture of content for an audio podcast.
There are various podcasting discussions around, too.

Any suspicion that how create and access pl sql web service returning multiple lines?
I use java not and do not have access to tools such as JDeveloper.
Thank you!
The real problem is that collection types are not supported for the return parameters.
The solution is to wrap the collection into another object.
Here is an example of work based on your settings:
CREATE OR REPLACE TYPE test_rec is OBJECT ( empno number(4) , ename varchar2(10) , hiredate date ); / CREATE OR REPLACE TYPE test_array AS TABLE OF test_rec; / CREATE OR REPLACE TYPE test_array_wrapper is OBJECT ( arr test_array ); / CREATE OR REPLACE PACKAGE test_pkg AS function get_rows(p_deptno in number) return test_array_wrapper; END; / CREATE OR REPLACE PACKAGE BODY test_pkg AS function get_rows(p_deptno in number) return test_array_wrapper is results test_array; begin select test_rec(empno, ename, hiredate) bulk collect into results from scott.emp where deptno = p_deptno; return test_array_wrapper(results); end; END; /
The wsdl is then generated correctly:
SQL> select httpuritype('http://DEV:dev@localhost:8080/orawsv/DEV/TEST_PKG/GET_ROWS?wsdl').getxml() from dual; HTTPURITYPE('HTTP://DEV:DEV@LOCALHOST:8080/ORAWSV/DEV/TEST_PKG/GET_ROWS?WSDL').GETXML() --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

EMPNAME MONTHS SALARY OVER_TIME
------------------------- ---------- -------------------- ----------
KATE 2000 NOVEMBER2014 300
HANS 5000 NOVEMBER2014 100
What I need is:
If the query above returns at least one record, it should display the line ' Yes. We have one or more employees who worked overtime in November2014'
before the documents are printed
Thus, the expected production is
Yes. We have one or more employees who worked overtime at the November2014
EMPNAME MONTHS SALARY OVER_TIME
------------------------- ---------- -------------------- ----------
KATE 2000 NOVEMBER2014 300
HANS 5000 NOVEMBER2014 100
If the query returns no records then usual 'no rows selected' isn't enough
Lothar G.f. says:
In fact, sql * more is no good tool for use considered.
Really? It may be a good reporting tool if you learn to use it as such...
for example
SQL > ttitle left 'Yes. We have one or more employees who worked overtime in November2014.
SQL > select * from emp where empno = 1234;no selected line
SQL > select * from emp where empno = 7788;
Yes. We have one or more employees who worked overtime at the November2014
EMPNO, ENAME, JOB HIREDATE DEPTNO COMM SAL MGR
---------- ---------- --------- ---------- -------------------- ---------- ---------- ----------
7788, SCOTT, ANALYST, 7566 19 APRIL 1987 00:00:00 3000 20This is just a basic example. It is possible to get SQL * more to ask for the required criteria and that the title could adjust according to this criterion, as well as the query building on it also.
However, the OP did not specify SQL * as the reporting tool, so there is little interest providing a complete solution which, until they specify what user interface that they are actually using.

How can I fill the records using the value LOV
Create a form based on the use of the following output Table EMP
Create a database block IE control-> Dept No. block
Create a database block - EMP
Create a LOV to the Dept not according to the dept table.
For the current No. Dept. Complete records of the employees
How can I fill the records using the value LOV?
Thank youHello
Create trigger KEY-LISTVAL for control_block.dept_no with code similar to the following:
IF SHOW_LOV ('LOV_NAME') THEN SET_BLOCK_PROPERTY ('EMP_BLOCK', DEFAULT_WHERE, 'DEPT_NO = ' || :CONTROL_BLOCK.DEPT_NO); GO_BLOCK ('EMP_BLOCK'); EXECUTE_QUERY; END IF;
Hope this helps

I can't write operating records
My hay program mast view some data from a controller. This with an Ethernet connection. I read everything and I can write coils bet I can't write operating records. I hope someone can help? Heir my VI: Rutte
With split or join in the digital numbers / range of data manipulation, you can take two U8 and join them in a single U16 (and vice-versa using split). And you can take two U16 and join them in an only U32.
Take a look at the attached Subvi, I did. It is a wrapper for the Modbus VI functions so that I could use enumerations to read or write specific registers by name and manage the manipulation of data as a result. It may call for a couple of typedef, that I created for my particular application, but that should not prevent you to see the structure and how I did the manipulation of data using the split and join.

Hello Mike,.
Thanks for posting your question on the Forum of the Microsoft community.
I understand that you have problems with a DVD, but I would like to learn more about the issue to provide you with better assistance.
- What do you mean when you say, 'I can't stop recording of data on a DVD?
- You talk about a blank rewritable DVD? It is specific to a particular disc?
- What is the accurate and complete error message when you say, 'this shows that a security error "?
- Are you able to eject the DVD? If so, what happens when you save the data without any disc in the drive?
I suggest you to provide the information identified above to refine the question and provide you with better assistance. Apart from that, you can try the mentioned below of methods based on specified corresponding understanding.
Method 1:
If you mean that the data you record are, by default, saved on the DVD player, then you can change the default save location as detailed below.
- Open libraries.
- Right-click on the Documents folder, and then click Properties.
- Click on restore the default settings.
- Repeat steps 2 and 3 for the musicfiles, photos and videos in the library.
Try to save all the data and check if the number is reproduced.
Method 2:
If you have problems with the specific DVD when inserted into the CD/DVD drive, you can try to let flow the next fixit and check if it helps.
