dbms_xmlgen using the pl - sql record type

Hello

I want the pl - sql record type and want to generate xml data. Registration of dbms_xmlgen access pl - sql can type instead of the query?

OR, please let me know any other packet pass pl - sql record type and generate XML data.

Thanks in advance

Registration of dbms_xmlgen access pl - sql can type instead of the query?

Do not think, but you can't go the individual components of record:

SQL> declare
  type rec is record
  (
    a   int,
    b   varchar2 (30)
  );

  r     rec;
  ctx   int;
  x     xmltype;
begin
  r.a := 1;
  r.b := 'Michael';

  ctx := dbms_xmlgen.newcontext ('select :x id, :y name from dual');
  dbms_xmlgen.setbindvalue (ctx, 'x', r.a);
  dbms_xmlgen.setbindvalue (ctx, 'y', r.b);
  x := dbms_xmlgen.getxmltype (ctx);
  dbms_output.put_line (x.getstringval ());
  dbms_xmlgen.closecontext (ctx);
end;

Android APP and Native application using the same push record ID

Hello

We have an Android existing converted app we use for BB10 platform that we are in the process of gradually. Replace this app is an application of BB10 Native with the same name and features.

My question is that I have to get a new record ID to push for the new Native application or can I use the existing production record ID?

Ideally, I would like to migrate my users off the coast of the old version of the application to the new with the least problems for customers.

Thank you

You should be able to use the same ID for this record.

There seems to be a problem with the software. We use the CS6 for Records services and when we try to save the record, part of the record is stored. Usually the recording to be saved as an mp3 file is 70 to 100 KB but recently only 3 KB are recorded. What should I do to fix this?

You may need to reset your preferences of hearing files stored in C:\Users\"username"\AppData\Roaming\Adobe\Audition\5.0. If you rename this folder in 5.0.bak that hearing won't find it when you open the next time if it will recreate a new settings with the default settings folder. See if hearing then works as expected.

Retrieve and display a result set using the dynamic sql?
Hi all

How would display a result set in Oracle using the dynamic SQL? Reason being, the table where I'd retrieve and display the result set is a GLOBAL TEMP TABLE created in a stored procedure. If I try to use the loop as usual, the compiler complains that the table does not exist. This makes sense because the compiler does not recognize the table because it is created dynamically. Here is an example:

create or replace PROCEDURE maketemptab IS
sql_stmt VARCHAR2 (500);
OutputString VARCHAR2 (50);

BEGIN
-create temporary table
sql_stmt: = ' CREATE of TABLE TEMPORARY GLOBAL globtemptab (id NUMBER, col1 VARCHAR2 (50))';
EXECUTE IMMEDIATE sql_stmt;
dbms_output.put_line ('... created table ');

-Insert a row into the temporary table
sql_stmt: = "INSERT INTO globtemptab values (1, 'some data of a test')';"
EXECUTE IMMEDIATE sql_stmt;
dbms_output.put_line ('... inserted row ');

-Insert a row into the temporary table
sql_stmt: = ' INSERT INTO globtemptab values (2, "some more test data");
EXECUTE IMMEDIATE sql_stmt;
dbms_output.put_line ('... inserted row ');

-Select the row on temporary table
sql_stmt: = 'SELECT col1 FROM globtemptab WHERE id = 1';
EXECUTE IMMEDIATE sql_stmt INTO outputstring;
dbms_output.put_line ('... selected line: ' | outputstring);

-drop temporary table
sql_stmt: = 'DROP TABLE globtemptab;
EXECUTE IMMEDIATE sql_stmt;
dbms_output.put_line ('... moved table ');

-display the result set
for tabdata loop (select col1 from globtemptab)
dbms_output.put_line ('... test of recovered data are' | tabdata.col1)
end loop;
end;

In short, how to rewrite the SQL below the comment "to display the result set" using the dynamic sql?

Thank you
Amedeo.
Hello

Try this:
```

   v_col1       VARCHAR2(30);

   sql_stmt := 'CREATE GLOBAL TEMPORARY TABLE globtemptab(id NUMBER, col1 VARCHAR2(50))';
   EXECUTE IMMEDIATE sql_stmt;
   dbms_output.put_line('...table created');

   -- insert row into temp table
   sql_stmt := 'INSERT INTO globtemptab values (1, ''some test data'')';
   EXECUTE IMMEDIATE sql_stmt;
   dbms_output.put_line('...row inserted');

   -- insert row into temp table
   sql_stmt := 'INSERT INTO globtemptab values (2, ''some more test data'')';
   EXECUTE IMMEDIATE sql_stmt;

Hello
Feew suggestions
(1) LONG is an obsolete type so if possible start working on this column change
(2) CLOB will be your favorite type of data on long.
(3) you cannot use RTRIM on long.

Here's a very quick example

drop table h
create table h (x long,y varchar2(100))
select rtrim(x) from h
select rtrim(y) from h

Solution:
[http://www.oracle.com/technology/oramag/code/tips2003/052503.html]

need to better implement the clob data type and

drop table h
create table h (x clob,y varchar2(100))
select  dbms_lob.substr( x, 4000, 1 ) from h
select rtrim(y) from h

See you soon!

Looking for example of the Manager to OBTAIN with the PL/SQL source type

Hello
I currently have a Manager GET job with a running QUERY source type in ADR 3.0. The call returns the number of records (hundreds, or even thousands of 10) in JSON and allows the user to navigate through the results.
The call accepts several parameters that I convey just in the place where the clause of the query in the Manager. Data is retrieved by the beach date (s).
To prevent queries runaway with ranges for a long time, I've implemented a logic in the sql statement to limit the applicant. The applicant requested an error thrown instead. There are other limits that I'm imposing on other entries I need to provide useful errors for example.
I would like to change the call GET use PL/SQL type instead of the type of REQUEST so that I can do validation on entries and send useful return error messages if necessary, however I can't find examples online.
Are there any examples (or alternatives) would be greatly appreciated.
Thank you
Anthony

You can use the Pipelined functions to generate your recordset plsql and then just use a select statement of the function in the pipeline in the service definition.

Creation of XML report using the PL/SQL stored procedure

Hi friends,
I'm working on a report xml with the xml source as a PL/SQL stored procedure.
I mean the fiscal year indicated in the following link to understand the process:
http://orclapp.blogspot.com/2012/02/developing-xml-publisher-report-using.html
In the example shown in the link above, I did not understand the following:
(1) in the following procedure, setting out "retcode" is not used at all.
What is the importance of this parameter.
REPORT PROCEDURE (errbuf OUT VARCHAR2, retcode OUT VARCHAR2, p_product_id in NUMBERS)
(2) after the xml data are prepared and updates 'l_result' variable Clob, what follows
Loop is executed. I am not able to understand why the following loop is required.
LOOP
EXIT WHEN l_length = l_retrieved;
IF (l_length - l_retrieved) < 32000
THEN
SELECT SUBSTR (l_result, l_retrieved + 1) IN l_xmlstr FROM DUAL;
l_retrieved: = l_length;
fnd_file.put_line (fnd_file.output, l_xmlstr);
ON THE OTHER
SELECT SUBSTR (l_result, l_retrieved + 1, l_offset)
IN l_xmlstr
FROM DUAL;
l_retrieved: = l_retrieved + l_offset.
fnd_file.put_line (fnd_file.output, l_xmlstr);
END IF;
END LOOP;
(3) in the example it is not explained how the concurrent program gets the xml data?
I guess that it is written to a file by using the following line of code:
fnd_file.put_line (fnd_file.output, l_xmlstr);
I would be grateful if someone can shed some light in my questions above so that I can well understand the process.
Thanks and greetings
Hawker

Hi 32000 in the code is a 'safe' than 32767 available max mesh, loops is intended to get around the entire thing into pieces that can be managed within the limits of the data type.

BTW; If you are in the following Oracle e-business, you can also use the Oracle reports very simply to create the XML output.

If you have reports developer all you need to do is put raw sql (create XML without any "Fireworks") in the SQL report and then set reporting in XML format in the definition of program in Oracle e-business.

Best regards

SQL mode not built using the default sql DBTYPE

When I have updated the SQL text in the view file PV_PERF_SR_VW in the designer of PeopleSoft, it updates the SQL text in the default DBTYPE value in the PSSQLTEXTDEFN table. But when I build the view, it seems to use the text in 2 DBTYPE SQL to generate the view. So the view does not build as we wish. Someone has experience on this?

When you open the SQL Editor in the App designer to enter your SQL text, there is a drop-down list at the top that you can use to specify the type of DB. It will be by default [Default], but if you expand the list, you can see one or several types of DB appear bold to indicate that SQL database exists. If any SQL database exists for the database you are using, then this prevail all SQL by default when you build the view. If you want to customize the SQL from this point of view, you must first select your database type from the dropdown list and then modify the SQL existing or remove it and then switch back to the default and make your changes.

In your particular case, DBTYPE 2 would indicate that Oracle-specific SQL exists to PV_PERF_SR_VW.

Kind regards

Bob

How can I use the USRP to record a signal using its two RX ports simultaneously?

Hello.

I am trying to record a signal using two antenna cone. The reason that I need two antenna to cover the bandwidth (DC - 6 GHz). a single antenna covers DC - 300 MHz and the other covers 300 MHz to 6 GHz. so I need to use two RX port of USRP at the same time to record the signal. I have two questions:

1. is this all USRP market capable of covering this frequency range?

2. is it possible to use the two RX port at the same time to the signals of the records I described? If this is not the case, how can do?

P.S. I have two NI2920 USRPs and two USRPs N210 in my lab.

Thanks in advance for your time.

Sam.

Hi Sam,

To answer your first question, the USRPs you can reach the bandwidth you want. There is not a USRP, to my knowledge, that can reach this range in a single device.

Also note that you can only use RX convened for two different ports at the same time using LabVIEW and the pilot of the USRP. If you want to use the two lines of RX, you will need to run a session with a single line, close the session and then start a different session for your second RX line.

Code horribly wrong!

Why this approach?

Dynamic SQL is almost NEVER needed in PL/SQL. And if you think it's necessary and taking into account what is displayed as being problems here, you have a 99% chance of being wrong.

This 1% where dynamic SQL is necessary, he will WITH bind variables to create shareable SQL, decrease memory requests, decrease the likelihood of a fragmented shared reel and decrease the burning CPU cycles on hard analysis.

An example below. Your approach is the 1st. One that is slower than the correct approach to 37 (x_!) ...

How to use the pl/sql procedure

Hi all,
How to use pl/sql packages and especially in what situations we are pl/sql, which is the cause of the procedure. Please explain with precision using small example.
Thanks and greetings
RAM

I could tell this at a very high level.

PL/SQL's procedural extension to SQL. SQL (structured query language) has no procedural capacity. They are executed as a stand-alone statement. When you want to generate a process flow with several SQL statement that you need to have a procedural language that could accommodate your SQL. PL/SQL is something similar to Java and Dot Net in this aspect. Said that PL/SQL is Oracle DB. This has some advantages. The most important thing is that when you have your SQL in PL/SQL oracle maintains its reliance on the object. Any database oracle related so you want to build, then you can consider to PL/SQL as the best way to use process flows.

PL/SQL provides various methods such as the PROCEDURE, FUNCTION and the PACKAGE. The only thing that race stands is in its ability to modularize your code. So, using the package you can create process workflows that is modular and easy to understand.

How to import metadata using the Oracle olap connection type

I'm trying to import metadata from MN,

I tried selecting the type of connection as oracle olap
DSN as host: port: sid

Can someone help me on this... :(
Hi Laszlo,

Finally fixed it by using the following URL

Separate values for the pre-treatment and results of the comprehensive review (without using the PL/SQL)

Hi people,
This year was difficult because it does not clearly justify what I want to achieve. The main reason for me to try this approach is to reduce the time of the performance. I have my program works very well, but since it accesses a view for each student, slows down the performance.

Purpose of this report: Show all Dates of examination for students, but only to display the results pre and review of the overall assessment on the first line for students.

Table scripts and INSERT statements:

create table STUDENT_TB(student_id varchar2(4), last_name varchar2(20), first_name varchar2(20), evaluation_date date);
create table EXAM_TB(student_id varchar2(4), exam_date date, result number);
create table EVALUATION_TB(student_id varchar2(4), eval_flag varchar2(1), sampling_date date);

insert into STUDENT_TB values('1001', 'Poppins', 'Mary', to_date('27-SEP-2012', 'DD-MON-YYYY'));
 
insert into EXAM_TB values('1001', to_date('20-APR-2011', 'DD-MON-YYYY'), 30);
insert into EXAM_TB values('1001', to_date('20-MAY-2012', 'DD-MON-YYYY'), 39);
insert into EXAM_TB values('1001', to_date('10-JUL-2012', 'DD-MON-YYYY'), 34);
insert into EXAM_TB values('1001', to_date('10-SEP-2012', 'DD-MON-YYYY'), 39);
insert into EXAM_TB values('1001', to_date('01-DEC-2012', 'DD-MON-YYYY'), 82);
 
insert into evaluation_tb values('1001', null, to_date('22-APR-2011', 'DD-MON-YYYY'));
insert into evaluation_tb values('1001', 'N', to_date('20-JUL-2012', 'DD-MON-YYYY'));
insert into EVALUATION_TB values('1001', 'Y', to_date('10-DEC-2012', 'DD-MON-YYYY'));

Desired output:

SID     Last Name   First Name   Evaluation Date    Exam Date   Results   Order   Pre Evaluation   Overall Evaluation   Accept?
===============================================================================================================================
1001     Poppins         Mary      27-SEP-12         20-APR-11     30       1           N                       Y            Y
1001     Poppins         Mary      27-SEP-12         20-MAY-12     39       2
1001     Poppins         Mary      27-SEP-12         10-JUL-12     34       3
1001     Poppins         Mary      27-SEP-12         10-SEP-12     39       4
1001     Poppins         Mary      27-SEP-12         01-DEC-12     82       5

Business rules:
The Pre, global assessment and accept it? fields are derived. The area of the pre assessment is derived from the EVALUATION_TBtable. Its the value of eval_flag where sampling_date < = evaluation_date.
In our example, the pre assessment should be an "n" while the overall assessment must be a 'Y '. The priority is Y-> N-> Null. The Accept flag is set to a 'Y' If a meadow at overall results past of N to Y or a NULL of Y value.

I have to return all the lines for the student that show the results of the reviews SQL is the following:
I need to join the view EVALUATION_TB. Simply join them of course would be a resulting vector product in 15 files that I don't want. I tried online (subqueries) but I failed again. Any help would be great!
I created the column ord_num to maybe help using only this folder to display the results of the assessment.

select x.student_id, x.last_name, x.first_name, x.evaluation_date,
       m.exam_date, m.result,
       dense_rank() over (partition by x.student_id order by m.exam_date) ord_num
from
(
  select  s.student_id, s.last_name, s.first_name, s.evaluation_date
  from    student_tb s
) x, exam_tb m
where x.student_id = m.student_id (+);

SID     Last Name   First Name   Evaluation Date    Exam Date   Results   Order
===============================================================================

1001     Poppins     Mary     27-SEP-12     20-APR-11     30     1
1001     Poppins     Mary     27-SEP-12     20-MAY-12     39     2
1001     Poppins     Mary     27-SEP-12     10-JUL-12     34     3
1001     Poppins     Mary     27-SEP-12     10-SEP-12     39     4
1001     Poppins     Mary     27-SEP-12     01-DEC-12     82     5

Thank you!

Hi Roxyrollers,

Please check your insert statements before posting. They have syntax errors.

The following query is to give you the desired result:

with pre_eval as
(
   select e.student_id
        , max(e.eval_flag) keep(dense_rank last order by e.sampling_date) eval_flag
     from evaluation_tb e join student_tb s
          on e.student_id=s.student_id
             and e.sampling_date <= s.evaluation_date
   group by e.student_id
)
,all_eval as
(
   select e.student_id
        , max(e.eval_flag) keep(dense_rank last order by e.sampling_date) eval_flag
     from evaluation_tb e join student_tb s
          on e.student_id=s.student_id
   group by e.student_id
)
, data_with_rank AS
(
   select s.student_id, s.last_name, s.first_name, s.evaluation_date
        , m.exam_date, m.result
        , dense_rank() over (partition by s.student_id order by m.exam_date) ord_num
     from student_tb s
          left outer join exam_tb m
          on (s.student_id = m.student_id)
)
select s.student_id, s.last_name, s.first_name, s.evaluation_date
     , s.exam_date, s.result
     , e.eval_flag as pre_eval
     , a.eval_flag as overall_eval
     , case when a.eval_flag='Y' and e.eval_flag!='Y' then 'Y' end accept
  from data_with_rank s
       left outer join pre_eval e
          on (s.student_id = e.student_id and s.ord_num=1)
       left outer join all_eval a
          on (s.student_id = a.student_id and s.ord_num=1)
order by s.student_id, s.exam_date;

STUDENT_ID LAST_NAME            FIRST_NAME           EVALUATION_DATE EXAM_DATE     RESULT PRE_EVAL OVERALL_EVAL ACCEPT
---------- -------------------- -------------------- --------------- --------- ---------- -------- ------------ ------

1001       Poppins              Mary                 27-SEP-12       20-MAY-12         39
1001       Poppins              Mary                 27-SEP-12       10-JUL-12         34
1001       Poppins              Mary                 27-SEP-12       10-SEP-12         39
1001       Poppins              Mary                 27-SEP-12       01-DEC-12         82

However, is not clear to me why the assessment are related only to the first line in the query.
The evaluation_tb table is in fact related to student_id and I expect to be connected all lines.

I've actually linked subqueries pre_eval and all_eval only in line with rank = 1 but I don't understand if that's correct according to business requirements.

Kind regards.
Al
