Hi all
There will be no effect in performance if we declare refcurosr with suspicion NOCOPY parameter in a Stored procedure procedure/package?
AFAIK variable refcursor who will make reference to the calling environment will hold just pointer not data and so avoid a NOCOPY effect.
Thank you!!
DS says:
One of my senior team members asked me to NOCOPY in all existing procedures where refcursor is returned as a parameter in my output project.
I told him that this will not add any performance improvement and has no effect.
I did it, because I was forced to do so.
Want to just check and take the advice from here in this forum.
I still have the document (in e-mails and in the procedure itself at the top) all these changes so that the future code-reviewers know EXACTLY why this change has been made and who authorized it. Probably you are asking your "senior" you say the reasons to support the change that they requested; You should document those as well.
Sounds like your "senior" team member is not so superior after all. You can use this as a topic of discussion in your dev group.
See the doc of the PL/SQL language.
http://docs.Oracle.com/CD/B28359_01/AppDev.111/b28370/tuning.htm#i48500
Calls to PL/SQL Tuning subprogramme with NOCOPY hint
By default,
OUTandINOUTparameters are passed by value. The values of aINOUTsettings are copied before the delivery of the subprogramme. During the execution of the subprogramme, temporary variables to maintain the output parameter values. If the subprogram exits normally, these values are copied to the actual parameters. If the subprogram exits with an unhandled exception, the original settings are unchanged.When the parameters represent structures of large data such as collections, records and instances of object types, this reproduction slows down execution and uses memory. In particular, this overload applies to each call to a method of the object: temporary copies are made of all attributes, so that any changes made by the method are only apply if the method ends normally.
To avoid this overload, you can specify the
NOCOPYtrick, which allows the PL/SQL compiler to passOUTandINOUTparameters by reference. If the subprogram exits normally, the action is the same as usual. If the subprogramme leaves at the beginning with an exception, the values ofOUTandINOUTparameters (or the attributes of the object) can still change. To use this technique, check that the subroutine handles all exceptions.Note the reference to the "large data structures. As you already know a REFCURSOR isn't a large data structure, so will not use NOCOPY.
The most important side effect is that, as noted in the last paragraph above, the characteristics of the 'exit' are modified if you use NOCOPY.
Point out that the last clause in your "senior": ENSURE THAT THE subprogram MANAGES all THE EXCEPTIONS.
Normally (i.e. without using NOCOPY) a REFCURSOR lucifera is a parameter OUT will NOT have a value if the procedure stops with an exception if the caller is unable to use it eventually. Maybe this isn't the case if you use NOCOPY.
Generally however, the use of NOCOPY would simply be an amendment unnecessary, but harmless.

execution of the procedure with refcursor as output parameter
Hi I have the package following a procedure with parameter as refcursor OUT.
Here is an example of sample with the same structure with name in the other table, handling exceptions in my dev environment
When I try to execute this procedure with the followig blockCREATE OR REPLACE PACKAGE TEST_PACK IS Type refCursor is REF CURSOR; PROCEDURE TEST_PROC (out_data out refCursor); END; CREATE OR REPLACE PACKAGE BODY TEST_PACK IS Procedure test_proc ( out_data out refCursor ) is -- v_sql varchar2(4000); -- begin v_sql := 'select * from emp'; DBMS_OUTPUT.PUT_LINE ( 'Select Query is: '||v_sql ); open out_data for v_sql; Exception when others then DBMS_OUTPUT.PUT_LINE ( 'Error '|| SQLCODE ||','||SQLERRM ); END; end ;

Disadvantages of using REFCURSORs of JDBC
Hello
Normally, I write my SQL inside Java (for example PreparedStatements) statements.
I am studying on the establishment of the PL/SQL Packages, providing the procedures and methods, I can call Java using CallableStatements. I understand the benefits of having a layer/API on the database side.
For example: extract some records in a table. (the PL/SQL function getCustomers returns a REFCURSOR)
-PreparedStatement (select... from... where...)->-> loop ResultSet executeQuery
-CallableStatement ("start?: = getCustomers();") end; ")-> cast getObject() to ResultSet-> loop ResultSet
---
What are the disadvantages of using the CallableStatement (REFCURSOR)?
Thank you, best regards, Stephan>
I was thinking about the extraction of the differences of lines (line single OR multiple rows per round trip to the DB).If I understand correctly, I can set the size of Fetch on a CallableStatement (Oracle), so to get several lines of the REFCURSOR per round trip ticket to the DB.
>
Recovery of data from an Oracle database using cursors: no exceptions.The JDBC layer is what includes the "batch processing" feature that you describe and the feature is independent of the source of the cursor. If you use Oracle extensions, so you can take advantage of automated dosing of Oracle.
Using a REF CURSOR is how preferred and recommended to provide data from the database to an external client.
1. it minimizes dependencies between the DB and the customer. The function/procedure that provides REF CURSOR is the only dependency.
2. it maximizes the security of the data. Responsibility to secure data is based only on the side DB through the function/procedure. It is simply not possible for the Client software to access the data not authorized unless the function/procedure he has. The customer has NO access to the data, except by the REF CURSOR.
3. it maximizes the security of the database. Access to the database itself is easier to control. Customers only need to access an account that has extremely limited privileges: privilege to EXECUTE the function/procedure. Customers should not any table, view, or other privileges to do their job.
4. it minimizes the probability of error by the customer. It is impossible for the client to access the bad table/view or data. Customers don't need to know how to join tables or even know what are the name of the table or where the data resides.
5. it minimizes the knowledge and skills that the client developer needs to do their work. The client developer can focus on their two main issues: 1) what data do I need for my application, 2) what do I do with this data.
6. the risk of 'performance' (or sentence) is if the procedure/function is misspelled or uses wrong written queries to get the data.
In short use a REF CURSOR allows the developer to DB deal with the best way to provide the data and the developer client side withj records how to consume these data.
Use of any solution other than a REF CURSOR should be the EXCEPTION rather than the rule.

Statement of the type of cursor in package/sp

I use the package with sp than using slider as below:

OPEN_CURS_01 RYBB. ORA_PK_TR2. CURS_01;

RYBB. ORA_PK_TR2. () ORA_SP_CUST

EXIT WHEN open_CURS_01% NOTFOUND;
DBMS_OUTPUT. PUT_LINE (TYPE_IN. COL1 | » '|| TYPE_IN. COL2); -/ sample
END LOOP;
END ;}
I need to put TYPE_IN declation of cursor inside the packaging, so the user who will run this pack/sp deals with this structure. How I can do this,
I tried to use < return RYBB. T_COLLECT % rowtype; > in the package but then I get:
Error (122,6): PLS-00455: cursor 'open_CURS_01' cannot be used in a dynamic OPEN SQL statement.
Not sure I can somehow in the BODY and make it available to the user?
Help you enjoy.

Published by: trento on 13 Sep, 2010 14:36Hello
Slider strong Ref (with a return type) cannot be used with dynamic SQL
because the compiler cannot check dynamic SQL return type during compilation.
String ref cursor can be used only with static SQL.
Dynamic SQL can be used only with the low (untyped) cursor variables.You can use static SQL in your procedure, look at this example:
create or replace PACKAGE TEST AS TYPE CURS_01 IS REF CURSOR RETURN SCOTT.EMP%ROWTYPE; Procedure ORA_SP_CUST (EXP_DATE IN date, open_CURS_01 IN OUT CURS_01 ); END TEST; / CREATE OR REPLACE PACKAGE BODY TEST AS PROCEDURE ORA_SP_CUST (EXP_DATE IN DATE, OPEN_CURS_01 IN OUT CURS_01 ) AS BEGIN OPEN OPEN_CURS_01 FOR SELECT * FROM SCOTT.EMP WHERE SCOTT.EMP.HIREDATE = EXP_DATE; END ORA_SP_CUST; END TEST; / VARIABLE CR REFCURSOR; BEGIN test.ORA_SP_CUST (TO_DATE('1981/12/03', 'yyyy/mm/dd'), :cr ); END; / print :cr CR --------------------------------------------------------------------------------------------------------------------------------------------------------------- EMPNO ENAME JOB MGR HIREDATE SAL COMM DEPTNO ---------------------- ---------- --------- ---------------------- ------------------------- ---------------------- ---------------------- ---------------------- 7900 JAMES CLERK 7698 1981/12/03 950 30 7902 FORD ANALYST 7566 1981/12/03 3000 20 -
problem with the collection and refcursor
I have the 'ServerDisconnect2' function below. It should return as 'ref_cursor' on the parameter that is a data container of deleted rows slider, Java developers insist on using this type of data/collection. I don't know how to code to return the values of ID removed as 'ref_cursor '. See commented "open pDeleteList" - sentence, it is commented as does not compile.
Is it possible to convert the variable 'vDeleteList' in ref_cursor?CREATE OR REPLACE PACKAGE oe_ctx AS TYPE gIntegerTable IS TABLE OF INTEGER INDEX BY BINARY_INTEGER; TYPE cursor_type IS REF CURSOR; .... PROCEDURE ServerDisconnect2(pCasinoCode NUMERIC, pCasinoServerCode NUMERIC, pChannelServerCode CurrentLogins.ChannelServerCode%TYPE, pDeleteList OUT cursor_type) IS vDeleteList oe_ctx.gIntegerTable; BEGIN DELETE FROM ( SELECT cl.* FROM CurrentLogins cl, Accounts a WHERE cl.CasinoCode = pCasinoCode AND cl.CasinoServerCode = pCasinoServerCode AND cl.ChannelServerCode = pChannelServerCode AND cl.Code = a.code AND a.Type = 'lplayer' ORDER BY a.code ) RETURNING Code BULK COLLECT INTO vDeleteList; /* OPEN pDeleteList FOR SELECT * FROM TABLE(vDeleteList);*/ COMMIT; END ServerDisconnect2;
So my only solution would be to open the ref_cursor BEFORE delete-clause with the same query delete clause has. But I'm afraid that then after opening the instant cursor after a milliseconds the deletion clause removes different lines and the procedure would be data incorrect in pDeleteList.

Reg. Converting a package in a Ref cursor level slider
Hi guru,.
I need to convert a package-level slider which contains the clause 'FOR UPDATE OF' in a Ref cursor when the query will be dynamically built with the necessary table name and other settings.
Using this slider many Update statement were made with the 'WHERE CURRENT OF' included in this clause.
Now, I've changed my Ref cursor cursor, but when I compile the cursor is dynamic based is not identified, because I get the error message.
Can someone tell me how to implement?
I need only go to dynamic bulding of the whole procedure.
Kind regards
Vijayasekaran.NMaybe you can use around the ROWID. Like this
Say what your actual code.
declare cursor c is select * from t for update of name; lno t.no%type; lname t.name%type; begin open c; loop fetch c into lno, lname; exit when c%notfound; update t set name = lno||lname where current of c; end loop; close c; end; /With refcursor you can do.
declare type rc is ref cursor; c rc; lno t.no%type; lname t.name%type; lrowid rowid; begin open c for 'select rowid rid, t.* from t for update of name'; loop fetch c into lrowid,lno, lname; exit when c%notfound; update t set name = lno||lname where rowid = lrowid; end loop; close c; end; /Published by: Karthick_Arp on December 26, 2008 02:00

refcursor out back of a function
Hello...
as the topic of this thread I have indicates wud like to know if it is possible to return an ouput refcursor from a function.coz' a FN can only return a value...
pls help me.
Thank you and best regards,CREATE OR REPLACE FUNCTION PRM_FN_GETHOP ( HOP IN VARCHAR2 , ProcessFor IN VARCHAR2, get_hop_cursor OUT SYS_REFCURSOR) RETURN varchar2 AS v_current_amount number; BEGIN if ProcessFor is null then select PPH_CUR_AMOUNT into v_current_amount from prm_p_hop where PPH_HOP_CODE=HOP; return v_current_amount; else open get_hop_cursor for select PPH_ARR_AMOUNT,PPH_LOP_AMOUNT,PPH_LOPR_AMOUNT from PRM_P_HOP where PPH_HOP_CODE=HOP; RETURN get_hop_cursor; END IF; END PRM_FN_GETHOP;user10422719 wrote:
Hello...of course... they are...!
the fn must have two the HOP and process
By pressing the Fn with a null value for the process... it must perform a select operation that chooses only one record
else... He must select three columns of a record...any thoughts on the use of case?
The function can return only one type of data. If 'a record' is the same structure as the "a record", then you can return to this structure, but if they are different, then the function is expanded wrongly.
If you use a package, you can overload your name of the function so that it recognizes when parameters are passed in and then each of the functions can return different types...

Uninstall software update Apple says error in seller contact package package unstaller
Try to get itunes working to make a backup of my faulty iphone before repair.
First-itunes does not start says error. I'm trying to fix it, who said success but same error when you try to start it.
Then uninstall completely worked. Then reinstall that seemed to be over except for a message "an older version of Apple software update already exists" then he went down and install itunes apparently had not been completed.
Then I try to remove the update from the apple software and executed by an error in the installation program - it says there is an error in the installation and contact the supplier of the installation package. Same error if I run the uninstall command line program.
Try to repair the Apple Software Update of programs & features Control Panel and then try to update iTunes again.
For general advice, see troubleshooting problems with iTunes for Windows updates.
The steps described in the second case are a guide to remove everything related to iTunes and then rebuild what is often a good starting point, unless the symptoms indicate a more specific approach.
Review the other boxes and other support documents list to the bottom of the page, in case one of them applies.
The more information box has direct links with the current and recent if you have problems to download, must revert to an older version or want to try the version of iTunes for Windows (64-bit - for older video cards) as a workaround for problems with installation or operation, or compatibility with third-party software.
Backups of your library and device should be affected by these measures but there are links to backup and recovery advice there.

Content of library photos - necessary Expert Package
I've had my MacBook for about 5 years now and I have an insane amount of Photos stored for the past 14 years, but during that time, my library of Photos being scenes has become a bit of a mess. (I think)
My photo library app itself is very good, but there a total of scatter gun approach to sync my Photos with iTunes (via a cable not iCloud) allows to synchronize some and not others. Now he has decided to not to sync album art by June 2016 for some strange reason.
I think that it has been corrupted and dare I say I have tinkered around with the "package contents" so I need help
What records I should have in the contents of package of Photos? I have the following: -.
Apple TV Photo Cache - I know it's for my Apple TV which is fine
Spare part - no article here
Data - photos contained here, no idea what it is for?
Data.noindex - photos contained here like above?
database
iPhotolock.data
iPod Photo Cache - I know that allows you to synchronize the photos to my iPhone and I deleted before you try and make it work
Masks - no article here
Masters - it's the only place where my original showing in Photos is kept? (14 items)
Plug-Ins - no article here
Previews - curious as to what this is?
Private - no idea what it is for?
ProjectDBversion.plist
Projects.DB
resources - no idea what this? Photos here too
Miniatures - what is - it used to? I had 16 points here, it should not match the masters?
I'd love to get it back to scratch so any ideas and would love someone to answer some of the questions above
You are chasing a dream - you may (0r can't) get the answers to all or part of these but he questions not because you can't fix anything and if you messes with the content library autour probably have corrupted you it
I daresay I could have tinkered around with the "contents of the package.
rather than wasting time on a quest usless you need
1 resolve to stay out of the inside of the library in the future - there is not serviceable by the user
2. now, either restore a working library from before you "tinkered" around
3 - or start over with a new library, then drag each file in master file to the icon in the Dock to import into the new library of Photos
