Need PL SQL Procedure

Hello All,
I like to write a PL SQL Procedure for the below sql statements. I like to pass all values from first sql stmnt to update columns in second sql stmnt based on dund_cc that is selecting from first sql stmnt. Please help me out how can I put together in pl sql procedure.
SELECT Y.DUND_CC, Y.DPPROP, Y.APPNMENT, Y.ALLOTMENT, Y.ALLOCATION, Y.BDGCT FROM ABCDX_TBL Y;
UPDATE POSDGET b SET B.DPPROP = Y.DPPROP, b.APPNMENT = Y.APPNMENT, b.ALLOTMENT = Y.ALLOTMENT,
b.Y.ALLOCATION = Y.ALLOCATION WHERE b.DUND_CC = Y.DUND_CC;
Thanks in Advance!!!

Hi,
You don't need a stored procedure or PL/SQL to do that. You can use a single UPDATE or MERGE statement, like this:
MERGE INTO       posdget     dst
USING   (
           SELECT dund_cc
        ,        dpprop
        ,        appnment
        ,        allotment
        ,        allocation
        ,        bdgct
        FROM        abcdx_tbl
        )               src
ON     (src.dund_cc     - dst.dund_cc)
WHEN MATCHED THEN UPDATE
SET     dst.dpprop     = src.dpprop
,     dst.appnment     = src.appnment
,     dst.allotment     = src.allotment
,     dst.allocation     = src.allocation
;The statement above will also work in PL/SQL, if you have a reason for doing it that way.

Need PL/SQL procedure for file transfer local system to server location

Hi Experts,
The requirement is one file ex: text file,excel file is there in Local system suppose c:newfolder/test.txt.
once run the concurrent program for this particular file in the local system should transfer into server location for the mentioned path.
is it possible to do in PL/SQL or shell script.
can you please share the code.
Thanks

Why is the Oracle database server to be used? For what purpose?
There are standard secure methods for a client to copy a file to a server. Such as sftp and scp. No complex Oracle database server layer needed in-between.
So why do you want to use the Oracle database to act as the copy mechanism for you?
It will only make sense if the local file is copied into the database (as a LOB or securefile) and managed by the database. I fail to see why Oracle should be acting as the go-between for the client file system copy process to the server file system. This introduces another moving part in the copy process. Adds more security issues. Adds more authentication issues. And what for?

Need to wite pl sql procedure for dynamic select statement

Need pl sql procedure for a Dynamic select statement which will drop tables older than 45 days
select 'Drop table'||' ' ||STG_TBL_NAME||'_DTL_STG;' from IG_SESSION_LOG where substr(DTTM_STAMP, 1, 9) < current_date - 45 and INTF_STATUS=0 order by DTTM_STAMP desc;

I used this to subtract any data older than 2 years, adjustments can be made so that it fits for forty five days, you can see how I changed it from the originaln dd-mon-yyyy to a "monyy", this way it doesn't become confused with the Static data in the in Oracle, and call back to the previous year when unnecessary:
TO_NUMBER(TO_CHAR(A.MV_DATE,'YYMM')) >= TO_NUMBER(TO_CHAR(SYSDATE - 365, 'YYMM'))

Setting up a project where ADO only needs to call procedures, no tables?

I am not sure if JDeveloper is the right tool, I'm just trying to prototype something to see if it would work.
Goal: Upload files into an item content region in Oracle Portal.
Using JDeveloper, It is pretty easy to upload file. Once I have the uploaded data, I would think that it would be pretty simple to call Portal APIs to upload_blob and add_item to get the uploaded file in an item content list.
I tried this with ApEx, but the problem being that ApEx was on a different database instance, and trying to pass blob_content over a database link, well, didn't work for me.
The key is a create a quick, simple application that just performs a file upload, then adds the content to Oracle Portal calling portal API's. Giving the end user an admin login to modify page content isn't really a good option. (laughing)
JDeveloper seems to be a good choice for this task, but I am not sure how to setup the ADF components. I need access to calling the pl/sql procedures and API that are in the portal schema.
So does anyone have some guidance on setting up ADF to do this?
Thanks, Ken

Shay,
I will work with the first example link.
The question: What is the correct way to use ADF components if the only thing I want is the ability to call stored procedures. In order to upload files, I would still need at least a view with transient objects that I can use to call the pl/sql procedures.
Thanks for the links! Ken

Need help in writing a tricky sql/PL/Sql Procedure

Hi,
I have a Branch table with just two fields in it node1 and Node2, The table looks like this
node1 | node2
-------|---------
1 | 2
3 | 2
3 | 4
4 | 5
1 | 5
1 | 6
5 | 6
in the above data if you draw lines between node_1 and node_2 you will see that there are 3 different paths to get from 1 to 5, as follows
/--------6-------\
1----------------------5
\2------3-------4/
Now I need to Find all the nodes between 1 and 5 or all the possible paths from node 1 to node 5 in this case I have 3 possible paths they are as follows
1-2-3-4-5
1-3-5
1-5
Now I know if this data was stored in a hierarchical manner I can get the results i want by using CONNECT BY and SYS_CONNECT_BY_PATH.
Is there a way to transform this data into a hierarchcal manner so that I can use the CONNECT BY or can somebody give me an Idea as to how to write a PL/SQL procedure to get the result I want.
Any help will be greatly appreciated

Hi!
1.Create another table Branch1 to hold 'transformed data'.
2.Use the following procedure to insert data into branch1 table.
declare
cursor n is select * from branch;
begin
for nrec in n loop
if nrec.node1 = 5 then
     insert into branch1(node1,node2) values(nrec.node2,nrec.node1);
elsif nrec.node2= 5 then
     insert into branch1(node1,node2) values(nrec.node1,nrec.node2);
else
if      nrec.node2> 5      then
     insert into branch1(node1,node2) values(nrec.node1,nrec.node2);
elsif nrec.node1> 5 then
     insert into branch1(node1,node2) values(nrec.node2,nrec.node1);
elsif (nrec.node1 < nrec.node2 ) then
     insert into branch1(node1,node2) values(nrec.node1,nrec.node2);
else
     insert into branch1(node1,node2) values(nrec.node2,nrec.node1);
end if;
end if;
end loop;
commit;
end;
3.Then execute the following connect by query:
SQL> select lpad(' ',level*2,' ')||node1 from branch1
2 start with node1=1
3 connect by prior node2=node1;
Hope this is satisfactory.
Thanks!

How to call a PL/SQL procedure from a xml Data Template

We have a requirement in which we need to call a pl/sql package.(dot)procedure from a Data Template of XML Publisher.
we have registered a Data Template & a RTF Template in the XML Publisher Responsibility in the Oracle 11.5.10 instance(Front End).
In the Data Query part of the Data Template , we have to get the data from a Custom View.
This view needs to be populated by a PL/SQL procedure.And this procedure needs to be called from this Data Template only.
Can anybody suggest the solution.
Thanks,
Sachin

Call the procecure in the After Parameter Form trigger, which can be scripted in the Data Template.
BTW, there is a specialized XML Publisher forum:
BI Publisher

Execute CDC mappings from a PL/SQL procedure

Hi,
I´m using OWB 11.2.0.2 for Linux. I´ve created some CDC mappings to update cubes with changes coming from other tables and cubes (from the tables that implement those cubes with the relational option). The issues are:
- The CDC mappings run successfully from the OWB (Project Navigator - Start), but I cannot execute them from a procedure in PL/SQL with the following code:
PROCEDURE "PROC_RUNCDCMAPPINGS" IS
--inicializar variables aquí
RetVal NUMBER;
P_ENV WB_RT_MAPAUDIT.WB_RT_NAME_VALUES;
-- ventana principal
BEGIN
RetVal:= BARIK.CDC_LOAD_CUBO_RECARGA.MAIN(P_ENV);
RetVal:= BARIK.CDC_LOAD_CUBO_TOR.MAIN(P_ENV);
RetVal:= BARIK.CDC_LOAD_CUBO_TOAE.MAIN(P_ENV);
RetVal:= BARIK.CDC_LOAD_CUBO_VIAJES.MAIN(P_ENV);
RetVal:= BARIK.CDC_LOAD_CUBO_TICKETINCIDENCIA.MAIN(P_ENV);
RetVal:= BARIK.CDC_LOAD_CUBO_LIQMONEDERO.MAIN(P_ENV);
RetVal:= BARIK.CDC_LOAD_CUBOS_LIQTEMPORALES.MAIN(P_ENV);
COMMIT;
END;
It doesn´t report any error (the value for RetVal after execution is 0), but the cubes are not loaded with changes, and the changes stored in the J$_%tables are not consumed.
Some of the options that may impact in the mappings are:
- All the CDC are of Simple type
- There are more than one subscriber to consume the changes, as for some tables, its changes must feed more than one CDC.
- All the mappings include only one execution unit per mapping.
- The integration/load template is the default: DEFAULT_ORACLE_TARGET_CT
Other question is: As I explained, I need more than one subscriber because same updates must be consumed by different CDC mappings, to load different cubes, but I´ve not been able to assign the subscribers to only the tables associated with them, so all the subscribers are subscribed to all the changes in all the CDC tables, but as many of those subscribers never consume the changes of same tables, in the J$_% tables remains the not consumed records, and I haven´t found the way to purge those tables (other than the delete from J$_), nor to assign the tables with the subscribers (so the subscribers are only subscribed to their interested changes, that will be consumed, so the tables will be emptied after the consumption).
Any help with these problems will be greatly appreciated.
Tell me if more info is needed to clarify the situation.
Best regards,
Ana

Hi David,
Thank you for your reply.
These mappings are the mappings needed to update the cubes with the changes detected by the CDC system, they are located under the Mapping Templates folder and I´m using code templates for the control of the loading and the integration (the DEFAULT_ORACLE_TARGET_CT) mapping.
What I need is to execute these mappings within a PL/SQL procedure that will be invoked from different tools.
I´ve done it for regular mappings (not CDC mappings), and it works. The code is the same as for the CDC ones:
PROCEDURE "PROC_RUNLOADMAPPINGS" IS
--inicializar variables aquí
RetVal NUMBER;
P_ENV WB_RT_MAPAUDIT.WB_RT_NAME_VALUES;
-- ventana principal
BEGIN
RetVal:= BARIK.LOAD_CUBO_RECARGA.MAIN(P_ENV);
RetVal:= BARIK.LOAD_CUBO_TOR.MAIN(P_ENV);
RetVal:= BARIK.LOAD_CUBO_TOAE.MAIN(P_ENV);
RetVal:= BARIK.LOAD_CUBO_VIAJES.MAIN(P_ENV);
RetVal:= BARIK.LOAD_CUBO_TICKETINCIDENCIA.MAIN(P_ENV);
COMMIT;
END;
-- End of PROC_RUNLOADMAPPINGS;
,and when I run it, the mappings are executed, but with the CDC ones it doesn´t (even when no error is reported).
I know that they are deployed in the selected agent (in my case the Default_Agent), but when I start them from the OWB, the mapping packages are created in the DB schema, so, I thought that maybe I could invoke them....so what you tell me is that the only way to invoke them is from SQL*Plus? not from a regular PL/SQL procedure?
Thank you very much,
Ana

PL/SQL procedure is 10x slower when running from weblogic

Hi everyone,
we've developed a PL/SQL procedure performing reporting - the original solution was written in Java but due to performance problems we've decided to switch this particular piece to PL/SQL. Everything works fine as long as we execute the procedure from SQL Developer - the batch processing 20000 items finishes in about 80 seconds, which is a serious improvement compared to the previous solution.
But once we call the very same procedure (on exactly the same data) from weblogic, the performance seriously drops - instead of 80 seconds it suddenly runs for about 23 minutes, which is 10x slower. And we don't know why this happens :-(
We've profiled the procedure (in both environments) using DBMS_PROFILER, and we've found that if the procedure is executed from Weblogic, one of the SQL statements runs noticeably slower and consumes about 800 seconds (90% of the total run time) instead of 0.9 second (2% of the total run time), but we're not sure why - in both cases this query is executed 32742-times, giving 24ms vs. 0.03ms in average.
The SQL is
SELECT personId INTO v_personId FROM (
        SELECT personId FROM PersonRelations
        WHERE extPersonId LIKE v_person_prefix || '%'
) WHERE rownum = 1;Basically it returns an ID of the person according to some external ID (or the prefix of the ID). I do understand why this query might be a performance problem (LIKE operator etc.), but I don't understand why this runs quite fast when executed from SQL Developer and 10x slower when executed from Weblogic (exactly the same data, etc.).
Ve're using Oracle 10gR2 with Weblogic 10, running on a separate machine - there are no other intensive tasks, so there's nothing that could interfere with the oracle process. According to the 'top' command, the wait time is below 0.5%, so there should be no serious I/O problems. We've even checked JDBC connection pool settings in Weblogic, but I doubt this issue is related to JDBC (and everything looks fine anyway). The statistics are fresh and the results are quite consistent.
Edited by: user6510516 on 17.7.2009 13:46

The setup is quite simple - the database is running on a dedicated database server (development only). Generally there are no 'intensive' tasks running on this machine, especially not when the procedure I'm talking about was executed. The application server (weblogic 10) is running on different machine so it does not interfere with the database (in this case it was my own workstation).
No, the procedure is not called 20000x - we have a table with batch of records we need to process, with a given flag (say processed=0). The procedure reads them using a cursor and processes the records one-by-one. By 'processing' I mean computing some sums, updating other table, etc. and finally switching the record to processed=1. I.e. the procedure looks like this:
CREATE PROCEDURE process_records IS
    v_record records_to_process%ROWTYPE;
BEGIN
     OPEN records_to_process;
     LOOP
          FETCH records_to_process INTO v_record;
          EXIT WHEN records_to_process%NOTFOUND;
          -- process the record (update table A, insert a record into B, delete from C, query table D ....)
          -- and finally mark the row as 'processed=1'
     END LOOP;
     CLOSE records_to_process;
END process_records;The procedure is actually part of a package and the cursor 'records_to_process' is defined in the body. One of the queries executed in the procedure is the SELECT mentioned above (the one that jumps from 2% to 90%).
So the only thing we actually do in Weblogic is
CallableStatement cstmt = connection.prepareCall("{call ProcessPkg.process_records}");
cstmt.execute();and that's it - there is only one call to the JDBC, so the network overhead shouldn't be a problem.
There are 20000 rows we use for testing - we just update them to 'processed=0' (and clear some of the other tables). So actually each run uses exactly the same data, same code paths and produces the very same results. Yet when executed from SQL developer it takes 80 seconds and when executed from Weblogic it takes 800 seconds :-(
The only difference I've just noticed is that when using SQL Developer, we're using PL/SQL notation, i.e. "BEGIN ProcessPkg.process_records; END;" instead of "{call }" but I guess that's irrelevant. And yet another difference - weblogic uses JDBC from 10gR2, while the SQL Developer is bundled with JDBC from 11g.

How do I delete cascade with a PL/SQL procedure?

This script will create a PL/SQL procedure that deletes cascade. This is a post to contribute to the Oracle community. Take the code as is and test it before you use it in production. Make sure this is what you want.
Procedure Delete Cascade (prc_delete_cascade)
Description
=============
The principle is very simple. The procedure uses a table called TO_BE_DELETED to keep a list of records to be deleted. This
table keeps the table name and the rowid of those records that need to be deleted. The procedure also uses a function called
DELETE_BOTT_ROW which takes one record of the table and tries to delete it. If the deletion fails with a foreign key constraint
violation, the function parses the SQL error message (SQLERRM) to get the name of the constraint. With the name of the constraint,
the function finds the name of the child table, all the child records that have references to the parent table primary or unique key,
and the parent key primary or unique key column name. Once the child records of the failed delete are identified, the function takes their table name and rowids
and records them into the TO_BE_DELETED table by inserting records of their table name and their rowids. Al the records inserted also contain the level (which
is 1 for the original records, 2 for child records, 3 for granchild records, etc.) and the sequence number of the order in wich they
are recorded. This way, when the function picks up a record to be deleted, it takes the one with the highest level and the highest
inserted sequence, or the "bottom" record. Once all the child records of the failed delete are appended to the TO_BE_DELETED table, it calls itself
recursevely, and the function takes the record at the "bottom" of the table and tries to delete it. If it succeeds, it calls
itself recursevely to delete the next record. If it fails, it goes and finds the child records as described before and once they are
inserted into the TO_BE_DELETED table, it calls itself again recursevely to try to delete again the "bottom" record. All records
that are successfully deleted are flagged as deleted usig the flag_del column so they are not pickt up again. Once all the (parent,
child, grandchild, etc.) records are deleted, the procedure ends without commiting, giving the option to the user to commit or
rollback deletions. The table TO_BE_DELETED is, at the end of the procedure, a list of all the records that were deleted, including their table names
and the order in with they were deleted. The user then can review its content and decide to commit or rollback.
Restrictions
============
1. Single tables only. The procedure only takes one table name and a WHERE clause to identified the records to be deleted.
2. Single columns only. Ther procedure only works with single-column primary, unique and foreign key constraints.
3. Single schema only.
4. Unpredictable results with circular references.

Interesting.
I see a few areas where this could be useful. Elimiating specific test records from a Test DB for example.
Some comments:
<li>Since this is a recursive logic you must add a stop criteria. In this case I would add a max iteration variable. If that one is reached, raise an error message and let the procedure stop with that error.</li>
<li>The when others exception at the end should be removed completely</li>
<li>The when others exception in the middle should be replaced by a specific exception that handles the -2292 error</li>
<li>A list of tables where no record should be deleted could be usefull. If the logic would encounter such a table, it should also stop. This would be to prevent that data from some system critical tables could be deleted per accident.</li>
<li>The reference from the FK constraint to the PK constraint should include the table name and if possible the owner (as long as you use user_* views the owner is always the same. But we could extend this to the ALL_* views). I never met a system where different tables have the identical FK constraint names, however just make this fool proof.</li>

Link to PL/SQL procedure using a Template Manager template.

Hi,
I need to link a portal application report (report from SQL query) to a SQL procedure that uses a template manager template. The PL/SQL procedure requires parameters. I'm not be able to create a link based on a PL/SQL procedure. The only solution I found is to setup a link to a Form based on that procedure. But the form is only used to call the PL/SQL procedure by clicking the submit button and redirect to the template.
Another question:
Is it planed to support dynamic links based on column conditions?
I'm using Portal release 3.0.7.6.2.
thanks in advance
Jens

Jens,
You may want to search the Oracle9iAS Portal Applications forum. It may have the answer you are looking for. This forum is for questions related to the Portal Development Kit.
Thanks,

Get the report list in a PL/SQL procedure

Hi to all,
I need to get the list of the personal report of a specified user in a PL/SQL procedure, is this possible?
My procedure should delete not "standard" report of a specified portal user.
Then i must have the list of all user's reports and after do my delete logic.
Jhon Dhon

Jhon -
It sounds to me that what you want to do is have a list that is generated based upon the identification of an individual. You can do this a number of ways, but I think you would want to write a straight query to accomplish this rather than a PL/SQL procedure. A query to accomplish what you're looking to do would look something like this:
SELECT
person_name,
person_id_number,
other info you need to see in the output
FROM
table_name (that contains the info you need to see)
WHERE
conditional clauses to obtain only data you wish to see
AND :p_person_id = table_name.person_id_number
The AND clause line will return the employee the user wishes to see based upon that person's ID number. This information is asked for in a parameter form before the report is run. The :p_person_id is referred to as a bind variable. You can read more about this on Metalink or OTN.
HTH,

Creating page items from pl/sql procedure and using them on a page

I have a page containing 2 select lists (P21_DEPARTMENTS and P21_DATE). Originally I added them as items that were "select list with submits". The problem is that based on the clearance level of the currently logged on user I only wanted the P21_DEPARTMENTS to be a select list if the user was an administrator. If however the user is not an admin then I want the page to have a hidden form field called P21_DEPARTMENTS that stores the user's department and has a label item that has the department name.
There is also a report region that generates a table based on the department selected from the select list (if the user is an admin) or the value stored in the hidden form field if the user is not.
My problem is that I cannot have both those items on the same page and use the HTML built-in authentication to determine which item should be rendered because I need to use the same ID for both items so that the stored procedure in my report region doesn't break. HTML does not permit items to share the same ID.
I tried to circumvent the problem by creating a stored procedure that performs all of the item rendering in the procedure and uses "htp.p()" to output all of my HTML code. This solution would allow me to pass a parameter into the procedure informing me as to whether or not the user is an administrator. If the user is an administrator the procedure would use a conditional statement and render a select list. If not, the hidden form field and label option would be used instead.
I finally got the stored procedure working perfectly. Now I am encountering the most bizarre thing. Since the "select list with submit" was not working (I used the same code that gets generated when I created other items using htmlDB's GUI) I decided to use a JavaScript function instead that gets triggered by the onChange event. I send along the value that is currently selected in the select list and in the function I set:
location.href='http://www.myoraclesite.com/pls/htmldb/f?p=111:21:729740000000000000::NO::P21_DEPARTMENTS:1';
In theory this should work. The problem is that it doesn't. The page reloads and the P21_DEPARTMENTS select list is not pre-selected.
The only thing I can think of is that when htmlDB generates page items that you've created with it's own admin tool it assigns some internal guid or something as opposed to when someone tries to generate dynamic page items of their own from a pl/sql procedure it's like the application doesn't even know they exist.
Any help would be GREATLY appreciated.
My only other solution would be to create a totally separate page (one for admin and another for non-admin). I would really like to avoid this.
Thanks in advance.

I would love to be able to generate my menus and
various other items in my htmlDB applications in much
the same way I can using ASP, PHP and Cold Fusion.
Users should have the ability to write server-side
code wherever they feel like it. The way htmlDB works
right now I spend more time trying to figure out how
to create simple effects and generate simple
interfaces when I need to be building a portal. Ami - it's important to understand that HTML DB is not like other languages. Thus, trying to force concepts which are common in other languages into HTML DB will often result in more work.
It's definitely worth the time to go over the HTML DB 2-day Developer, which can be found here: http://www.oracle.com/technology/products/database/htmldb/pdf/B14377_01.pdf
I can build a portal using Classic ASP, C#, PHP or Cold
Fusion in like 1/10 of the time that it takes me to
build one using htmlDB. I understand that this is not
meant for the hard-core programmer but no web
programming application in today's day and age should
prevent experts from getting under the hood.And I can build a Portal in HTML DB in 1/10 the time it will take me to do it in any other language. It's like anything else - proficiency comes with practice and work.
As for getting under the hood, there is plenty of places you can do that with HTML DB. Keep in mind that HTML DB itself is an HTML DB application, so the limits on what you can build with HTML DB are virtually limitless.
Sorry for the vent there. After spending the last 2
days trying to figure out how to implement such a
straightforward thing and now being informed that it
can't be done kind of bugged me.I understand your frustration, as I've been there before. My rule for beginners is that if you are writing more than a line or two of code in the first week, you're doing something wrong. Stop, take a break, and then use the ample resources (including searching this forum) to help solve your problem. There are plenty of resources available for you to learn about HTML DB on the HTML DB home page: http://otn.oracle.com/htmldb
Good luck,

Returning Multiple Rows From DBAdapter Calling PL/SQL Procedure

Oracle XE 10g Express Edition
JDeveloper 11.1.1.2.0
WebLogic Server 11g
Guys,
I have a table of orders, which I need to interrogate, and pass back any matching rows which meet certain criteria (e.g. status = 'OPEN').
However, rather than create a DBAdapter using an Operation Type of "Peform an Operation on a Table/Select", I need to use an Operation Type of "Call a Stored Procedure or Function".
I therefore need the procedure to return all the matching rows, rather than a single row.
I have looked at declaring return parameters for the procedure of the following types:
RECORD - is good because it allows me to return the elements of the row with their correct datatypes, but does not meet my needs because it will only support the return of a single row.
VARRAY - good because it can contain many row elements, but not good because it only supports a single row return, and also because all elements of the VARRAY must be of the same data type.
TABLE - good because it can contain many rows, but bad because each row can contain only two elements - the index element and the data element.
I think I could first define a RECORD (to hold a row), and then define a TABLE, with the data element being the RECORD, but I have found JDeveloper very fussy indeed when dealing with 'non-standard' data types in the DBAdapter.
Apologies if I am missing something obvious, but can anyone suggest a way of doing this?
Many thanks in advance.

Hi, I've been able to create process that seems to work. My platform is a but different but I don't think this is important for your question.
Here is the PL/SQL code. Just make Db Adapter for Calling stored procedure and it returns all rows!
Be aware of possible limitations on how manyrows you could return in one select! This can have severe impact on performance.
Succes.
