Need help with Ref Cursor

Dear All,
Version : '11.2.0.2.0'
I have a procedure which gets called from a screen ( on .Net) if use pushes a particular button.
The procedure takes 15 minutes to complete.
My requirement is to intimate the front end(.Net) as soon as the procedures gets called successfully without waiting for its completion as it is going to take 15 mins.
The reason being, the front end will popup a message saying that " The process is going to take long time, A mail will be sent to u after its completion" once it has been intimated that the procedure has been called successfully.
Could you please suggest can i return a cursor to front end without even manipulating the data.
i hope my question is understandable.

It seems to me that your problem is not an Oracle one, but a user interface one.
I'm assuming the slowness of the procedure is due to how long it's taking to query the data, and if you can't speed that up then, to have the procedure return a ref cursor, the connection between the front end and the procedure must be maintained (the process on Oracle must belong to a session, and the front end needs to be connected to that session).
So, you can't have Oracle go off and start a seperate process and then pass back the ref cursor when it's finished, because even though you can spawn off seperate processes such as using DBMS_JOB or DBMS_SCHEDULER, they will run in their own 'session' and the calling code won't keep a hold on any of those sessions... they're effectively stand-alone and seperate.
What you'll have to do is likely get your .net application to spawn off a child process to the main app, that presents the message saying it'll take some time, does the call to Oracle and waits for Oracle to return the resultant ref cursor, which it can then pass back to the main application etc. Due to .net allowing for multi-tasking, that is where the split processing should take place.

Need help about ref cursor using like table

Hi Guys...
I am devloping package function And i need help about cursor
One of my function return sys_refcursor. And the return cursor need to be
join another table in database . I don't have to fetch all rows in cursor
All i need to join ref cursor and another table in sql clause
like below
select a.aa , b.cc form ( ref_cursor ) A, table B
where A.dd = B.dd
I appeciate it in advance

My understanding is that you have a function that returns a refcursor and is called by a java app.
Because this is a commonly used bit of code, you also want to reuse this cursor in other bits of sql and so you want to include it like table in a bit of sql and join that refcursor to other tables.
It's not as easy as you might hope but you can probably achieve this with pipelined functions.
Is it a direction that code should be going down? yes, eventually. I like the idea of pulling commonly used bits of code into a SQL statement especially into the WITH section, provided it could be used efficiently by the CBO.
Is it worth the effort given what you have to do currently to implement it? possibly not.
what else could you do? construct the sql statement independently of the thing that used it and reuse that sql statement rather than the refcursor it returns?

Need Help: Using Ref Cursor in ProC to call a function within a Package

I'm calling a function within a package that is returning a REF CURSOR.
As per the Oracle Pro*C Programmer's Guide, I did the following:
1) declared my cursor with a: EXEC SQL BEGIN DECLARE SECTION and declared the cursor as: SQL_CURSOR my_cursor;
2) I allocated the cursor as: EXEC SQL ALLOCATE :my_cursor;
3) Via a EXEC SQL.....END-EXEC begin block
I called the package function and assign the return value to my cursor
e.g. my_cursor := package.function(:host1, :host2);
Now, the only difference between my code and the example given in the Pro*C Programmer's Guide is that the example calls a PROCEDURE within a package that passes back the REF CURSOR as an OUT host variable.
Whereas, since I am calling a function, the function ASSIGNS the return REF CURSOR in the return value.
If I say my_cursor := package.function(:host1, :host2); I get a message stating, "PLS-00201: identifier MY_CURSOR" must be declared"
If I say :my_cursor := package.function(:host1, :host2); I get a message stating, "ORA-01480: trailing null missing from STR bind value"
I just want to call a package function and assign the return value to a REF CURSOR variable. There must be a way of doing this. I can do this easily in standard PL/SQL. How can this be done in Pro*C ???
Thanks for any help.

Folks, I figured it out. For those who may face this problem in the future you may want to take note for future reference.
Oracle does not allow you to assign the return value of a REF CURSOR from a FUNCTION ( not Procedure - - there is a difference) directly to a host variable. This is the case even if that host variable is declared a CURSOR variable.
The trick is as follows: Declare the REF CURSOR within the PL/SQL BEGIN Block, using the TYPE statement, that will contain the call to the package function. On the call, you then assign the return REF CURSOR value that the function is returning to your REF CURSOR variable declared in the DECLARE section of the EXEC SQL .... END-EXEC PL/SQL Block.
THEN, assign the REF CURSOR variable that was populated from the function call to your HOST cursor varaible. Then fetch this HOST Cursor variable into your Host record structure variable. Then you can deference individual fields as need be within your C or C++ code.
I hope this will help someone facing a deadline crunch. Happy computing !

Need help with loop cursor

Hi,
I'm doing a data conversion and am fairly new to PL/SQL.
I have a cursor and in the loop i have a select statement
which returns ORA-01403(no data found). I need to skip this
row in the cursor and continue with the next.
BEGIN
OPEN cur_fill_split;

FETCH cur_fill_split into S_ASR,S_CLIENT_NO, S_DIRCODE, S_SPLIT_RATE, I_WAYS,

Hi,
I think there r 2 methods, one is by giving begin - end inside the loop as shown below 1st ex:
& the 2nd method is by selecting the record count & then based on that value executing further commands.
I think 2nd method is more safer than the 1st method.
Method 1:
1)
-- ---------------Procedure Begin------------------
BEGIN
OPEN cur_fill_split;
LOOP
FETCH cur_fill_split into S_ASR,S_CLIENT_NO, S_DIRCODE, S_SPLIT_RATE, I_WAYS,
S_BRANCH_NUMBER, S_BRANCH_NAME, S_DIV_NUMBER, S_DIV_NAME, S_ITEMCODE, S_LINE;
EXIT WHEN cur_fill_split%NOTFOUND;
select order_number INTO N_ORDER_NUMBER from order_header
where cmr_number||client_number||dir_number = s_asr||s_client_no||s_dircode;
BEGIN
SELECT SEQ INTO I_SEQ FROM ORDER_DETAIL
WHERE ORDER_NUMBER = N_ORDER_NUMBER
AND LINE_ORDER_NUMBER = TO_NUMBER(S_LINE);
EXCEPTION
WHEN NO_DATA_FOUND THEN
NULL;
END;
END LOOP;
CLOSE cur_fill_split;
END;
-- ---------------Procedure End------------------
Method 2)
By selecting the record count & based on that records, deciding the program control.
-- ---------------Procedure Begin------------------
declare
rec_cnt number := 0;
BEGIN
OPEN cur_fill_split;

FETCH cur_fill_split into S_ASR,S_CLIENT_NO, S_DIRCODE, S_SPLIT_RATE, I_WAYS,

where cmr_number||client_number||dir_number = s_asr||s_client_no||s_dircode;
/* Here we are using cnt variable & checking for
the record count, if count = 0, then it will skip */
select count(*) into rec_cnt from ORDER_DETAIL
WHERE ORDER_NUMBER = N_ORDER_NUMBER

if rec_cnt > 0 then
SELECT SEQ INTO I_SEQ FROM ORDER_DETAIL

Need help with OCI8::Cursor object

I'm using ActiveRecord::Base.connection.execute to run a SQL statement against an Oracle schema that is "external" to my Rails database.
I'm building the connection on the fly using connection parameters stored in my Rails database (MySQL).
So far so good...I can create the connection and run the query...I'm getting back an OCI8::Cursor object and that's where I'm stuck.
I need to display the results of the query in a Rails view.
New to Ruby and I'm not sure how to proceed.
Here's what I'm getting back:
#<OCI8::Cursor:0xb76c679c @stmttype=1, @svc=#<OCISvcCtx:0xb76c6c24>, @env=#<OCIEnv:0xb7765928>, @defns=[nil, #<OCIDefine:0xb76c5d10>, #<OCIDefine:0xb76c5cd4>, #<OCIDefine:0xb76c5c5c>, #<OCIDefine:0xb76c5bf8>, #<OCIDefine:0xb76c5bd0>, #<OCIDefine:0xb76c5ba8>, #<OCIDefine:0xb76c5b80>, #<OCIDefine:0xb76c5b58>, #<OCIDefine:0xb76c5b30>, #<OCIDefine:0xb76c5b08>, #<OCIDefine:0xb76c5ae0>, #<OCIDefine:0xb76c5ab8>, #<OCIDefine:0xb76c5a90>, #<OCIDefine:0xb76c5a68>, #<OCIDefine:0xb76c5a40>, #<OCIDefine:0xb76c5a18>, #<OCIDefine:0xb76c59f0>, #<OCIDefine:0xb76c59c8>, #<OCIDefine:0xb76c59a0>, #<OCIDefine:0xb76c5978>, #<OCIDefine:0xb76c5950>, #<OCIDefine:0xb76c5928>, #<OCIDefine:0xb76c5914>, #<OCIDefine:0xb76c58d8>, #<OCIDefine:0xb76c58b0>, #<OCIDefine:0xb76c5888>, #<OCIDefine:0xb76c5860>, #<OCIDefine:0xb76c5838>, #<OCIDefine:0xb76c5810>, #<OCIDefine:0xb76c57e8>, #<OCIDefine:0xb76c57c0>, #<OCIDefine:0xb76c5798>, #<OCIDefine:0xb76c5770>, #<OCIDefine:0xb76c5748>, #<OCIDefine:0xb76c5720>, #<OCIDefine:0xb76c56f8>, #<OCIDefine:0xb76c56d0>, #<OCIDefine:0xb76c56a8>, #<OCIDefine:0xb76c5680>, #<OCIDefine:0xb76c5658>, #<OCIDefine:0xb76c5630>, #<OCIDefine:0xb76c5608>, #<OCIDefine:0xb76c55e0>, #<OCIDefine:0xb76c55b8>, #<OCIDefine:0xb76c5590>, #<OCIDefine:0xb76c5568>, #<OCIDefine:0xb76c5540>, #<OCIDefine:0xb76c5518>, #<OCIDefine:0xb76c54f0>, #<OCIDefine:0xb76c54c8>, #<OCIDefine:0xb76c54a0>], @binds=nil, @ctx=[32, #<Mutex:0xb76c6c38>, nil, 65535], @parms=[#<OCIParam:0xb76c66c0>, #<OCIParam:0xb76c66ac>, #<OCIParam:0xb76c6698>, #<OCIParam:0xb76c6684>, #<OCIParam:0xb76c6670>, #<OCIParam:0xb76c665c>, #<OCIParam:0xb76c6648>, #<OCIParam:0xb76c6634>, #<OCIParam:0xb76c6620>, #<OCIParam:0xb76c65f8>, #<OCIParam:0xb76c65e4>, #<OCIParam:0xb76c65d0>, #<OCIParam:0xb76c65bc>, #<OCIParam:0xb76c65a8>, #<OCIParam:0xb76c6594>, #<OCIParam:0xb76c6580>, #<OCIParam:0xb76c656c>, #<OCIParam:0xb76c6558>, #<OCIParam:0xb76c6544>, #<OCIParam:0xb76c6530>, #<OCIParam:0xb76c651c>, #<OCIParam:0xb76c6508>, #<OCIParam:0xb76c64f4>, #<OCIParam:0xb76c64e0>, #<OCIParam:0xb76c64cc>, #<OCIParam:0xb76c64b8>, #<OCIParam:0xb76c64a4>, #<OCIParam:0xb76c6490>, #<OCIParam:0xb76c647c>, #<OCIParam:0xb76c6418>, #<OCIParam:0xb76c638c>, #<OCIParam:0xb76c62c4>, #<OCIParam:0xb76c61e8>, #<OCIParam:0xb76c6080>, #<OCIParam:0xb76c6058>, #<OCIParam:0xb76c5fcc>, #<OCIParam:0xb76c5fb8>, #<OCIParam:0xb76c5f68>, #<OCIParam:0xb76c5f54>, #<OCIParam:0xb76c5ea0>, #<OCIParam:0xb76c5e64>, #<OCIParam:0xb76c5e14>, #<OCIParam:0xb76c5e00>, #<OCIParam:0xb76c5dec>, #<OCIParam:0xb76c5dd8>, #<OCIParam:0xb76c5dc4>, #<OCIParam:0xb76c5db0>, #<OCIParam:0xb76c5d9c>, #<OCIParam:0xb76c5d88>, #<OCIParam:0xb76c5d74>, #<OCIParam:0xb76c5d60>], @stmt=#<OCIStmt:0xb76c6760>>
My problem is that I simply don't have a firm enough grasp on the basics of Ruby to dissect this thing and get at it's innards.
If someone could drop me a code snippet that shows how to reference the contents of this in my erb file I think I'll be off to the races.

If you want low level access to Oracle database then you can use ruby-oci8 API directly without using ActiveRecord.
You can read about ruby-oci8 API at http://ruby-oci8.rubyforge.org/en/api.html
But if you want to use ActiveRecord then install and use oracle_enhanced adapter, see http://wiki.github.com/rsim/oracle-enhanced
If you have any questions about oracle_enhanced adapter then probably it is better to ask them in http://groups.google.com/group/oracle-enhanced discussion group.
It is not recommended approach to establish ActiveRecord connection and then use low level ruby-oci8 API.
And if you have some problem then please describe exactly what you are doing and what you would like to achive and then also what error do you get.

Urgen I need help with a cursor

this my cursor, I created it in a button trigger
DECLARE

ins_pru_cod resultado_v.des_pru_codigo%TYPE;
cursor res_cur IS
select mue_id, des_pru_codigo from resultado_v where mue_id = :entrar_muestra.mue_mue_id;

commit;
END LOOP;
CLOSE res_cur;
END;
Something's is wrong because no results were obtained. Please I need yours help

First of all, I have to correct my previous posting : point 2 was wrong, that type of error can't happen in a cursor, probably I was inattentive :-(
That said, if the query works correctly in Sql*Plus, then the only difference I can guess is in fields definitions : how are mue_id and :entrar_muestra.mue_mue_id defined ?
As Frank suggested I'd put a message within the loop to see if and what is read.

Need help with a simple process with FTP Adapter and File Adapter

I am trying out a simple BPEL process that gets a file in opaque mode from a FTP server using a FTP adapter and writes it to the local file system using a File Adapter. However, the file written is always empty (zero bytes). I then tried out the FTPDebatching sample using the same FTP server JNDI name and this work fine surprisingly. I also verified by looking at the FTP server logs that my process actually does hit the FTP server and seems to list the files based on the filtering condition - but it does not issue any GET or RETR commands to actually get the files. I am suspecting that the problem could be in the Receive, Assign or Invoke activities, but I am not able identify what it is.
I can provide additional info such as the contents of my bpel and wsdl files if needed.
Would appreciate if someone can help me with this at the earliest.
Thanks

Need help with interface development

Hi i need help with requirement below with developing interface between or online order system and sap plz lemme know what is bapi i use for creating customer, update and assigining partner id to costumer.
SAP Development
1.     Using standards SAP functional module (with BAPI), create interface that will create/change Ordering party customer in SAP. Following fields are mandatory for customer creation:
     MANDT     Client
     VKORG     Sales organization
     VTWEG     Distribution Channel
     SPART     Division
     KDGRP     Customer Group (= ZORP)
     KUNNR     Customer number
     NAME1     Name 1
     NAME 2     Name 2 (if required)
     SORTL     Search term (short description)
     ZZALTKN     Search term 2 (old customer number)
     LAND1     Country
     ORT01     City
     PSTLZ      Zip Code
     REGIO      Region (state in USA)
     STRAS     Street
     TELF1     Primary telephone number
     TELFX     Primary Fax number
     ZZPRPLANS     Payment Plan
     CCINS     Payment card: Card type
     CCNUM     Payment cards: Card number
     CCDEF     Payment Card: Default Card Indicator
     ZBDGID     Customer Budget ID
     ZHOLD     Budget Hold indicator
     ZZCOSTCENT     Cost Center
2.     Upon successful customer creation system will issues S (success) message that customer has been created.
3.     New ordering party customer created in step ½, will have to be assigned as new partner to its belonging Sold-to/Ship-to customer. Use standard SAP customer functional module in order to perform this partner ID assignment. Partner ID for ordering party should be ZO.
1.7     Enhancement Functionality
Apart from creating a new interface to do the required functionality, the Order Create Interface also has to be changed to accommodate a field to pass the Ordering Party Number on the Order. The technicalities of how we are going to implement the interface will be laid out in the Tech Specs.
Thanks
in advance

Project Server 2013: I am using Project Server Permission Mode and need help with permission assignments?

Hi
Project Server 2013: I am using Project Server Permission Mode and need help with permission assignments?
How can I change Permissions for the individual users to see specific projects or all projects in project center and to see specific quick launch items?
For Example: if i have 4 users, A, B, C and D. what i want is:
User A can see everything and act as a project manager or Admin.
User B can view all projects in project centre but can change the schedule or resource assignment etc.
User C can only act as approver of projects and can view all projects in project centre.
User D can only view specific projects for which permissions are given.
can i have some expert help in sorting and understanding permission modes... as i was playing with project server mode permissions and can't figure out how to apply the above scenario to set of my user.
Thanks in Advance
Cheers

Hi Ajay,
Please refer to this link for detailed explanations about PS2013 security model.
http://technet.microsoft.com/en-us/library/cc197638(v=office.15).aspx
Actually, it will take a couple of days to explain in detail the security model that is a fundamental and tricky aspect of every PS implementation. But basically, you NEVER set permissions for a single user. You have groups in which your insert users. Groups
define "what users can do". Then you associate groups to a corresponding category. Categories define "what user can see". Thus the association of a group with a category will set "what the user can do on the objects he can see". Then, for more advanced security
level, you can use the RBS that will consist in "branches" in which you'll insert users. Based on those branches, you'll customize categories to fine-tune what user can see (for projects and resources) depending on the RBS branch and level.
I'd advice you to start "playing" in a test environment with the default categories/groups that might probably cover your need.
Concerning your 4 users:
user A : add him to the "administrator" group. Be careful that you're mentionning either project manager or administrator, which are 2 groups/categories with totally different permissions level.
user B : basically can see everything and change everything? it could be in the project manager group, assuming that there are no project visibility restrictions on the category via the RBS.
user C : waht do you mean by "approver"? Workflow approvals? Then it will be the portfolio manager group. Task update or timesheet approval? Then it is another long topic: please refer in the documentation to the "status manager" and "timesheet manager"
concepts. There are not related to the security model. In a few words, the status manager is the owner of the project plan, is defined for each task and approves tasks updates. The timesheet manager is an attribute defined for each resource in its parameters
and approves resource timesheet.
user D : you have to define which permission level must be given to this user. Basically it could be a team member that will see only projects he's in the project team. Note that team member cannot interact with the project plan in another way than submitting
timesheets and/or tasks updates which must be approved.
Once more, those are large and complex subjects that require a deep dive into your business model and tons of tests in a test environment.
Hope this helps.

I think I need help with driver (software) settings for D110a

I think I need help with driver (software) settings for D110a all-in-one
Product: D110a all-in-one
OS: Windows XP Professional
Error messages: None
Changes before problem appeared: None--new installation
The quality of photo images (mostly JPG files) in printouts is awful even though the files display beautifully on the PC screen. I am using
IrfanView software for displaying/printing. As far as I can tell, IrfanView is not the problem.
When I print the same images on a Deskjet 5150 attached to a different PC also running XP Pro and IrfanView, the quality of the printouts is at
least acceptable, Some would probably say good or very good.
It's dificult to explain in words the problem with the printouts. A picture of really pretty vegetables (squashes, tomatoes, watermelon, etc) comes
out much too red. Moreover, the red, which appears shaded on the screen, seems to be all one shade in the D110a printouts.
Something similar happens to a view of a huge tree in full leaf. On screen, there are subtle variations in the "greenness" of the leaves. In the
printout, all green is the same shade. In the same printout, the trunk of the tree is all a single shade of grey. It isn;t even obvious that the
trunk is a round, solid object.
I liken the effect to audio that disappears entirely when you lower the volume and gets clipped into square waves in even moderately loud passages.
I don't know whether the D110a driver software permits adjusting the parameters that appear to be set incorrectly, and if adjustments are possible,
how I would identify which parameters to adjust, how I would access them, or how I would adjust them. I'm hoping that someone can help. Thanks.
I forgot to mention that I have used the diagnostic application and it tells me that there are no problems.

Hi everyone,
I noticed the following message when network starts on my gateway
Warning: This functionality is deprecated.
Please refer to /etc/rc.conf on how to define a single wired
connection, or use a utility such as netcfg.
Then I realized the way network settings should be written in rc.conf has changed. But I can't figure out how this should be done.
Currently, my set up is the following (old way):
INTERFACES=(eth0 eth1)
eth0="dhcp"
eth1="eth1 192.168.0.10 netmask 255.255.255.0 broadcast 192.168.0.255"
ROUTES=(!gateway)
eth0 is on DHCP because the IP is dynamically assigned my ISP.
eth1 has a fix IP because it's on the LAN side.
No problem to use DHCP on eth0 with the new settings.
But for eth1, I don't know what I am supposed to write for gateway.
Wiki isn't clear on that one either, and it looks like many articles still refer to the old way.
Any guidance appreciated, thanks.
brazzmonkey,
you can't define 2 interfaces the old way (even though I saw some tricky workaround somewhere in the forums).
Use, f.e., netcfg:
Comment your old lines.
In /etc/rc.conf insert:
NETWORKS=(Eth0-dhcp Eth1-static)
DAEMONS=(..... !network @net-profiles ....)
In /etc/network.d create 2 files:
First one is named Eth0-dhcp.
Contents:
CONNECTION="ethernet"
DESCRIPTION="Whatever text"
INTERFACE=eth0
HOSTNAME="your hostname"
IP="dhcp"
DHCP_TIMEOUT=15
Second one is named Eth1-static.
Contents:
CONNECTION='ethernet'
DESCRIPTION='whatver'
INTERFACE='eth1'
HOSTNAME='hname'
IP='static'
ADDR='192.168.0.10'
GATEWAY='192.168.0.1' # your gateway IP
DNS=('192.168.0.1') # your DNS server
The names Eth0-dhcp and Eth1-static are not magic. They just must be the same in rc.conf and in /etc/network.d.
Hope it helps.
mektub
PS: netcfg must be installed.

PLS-00428 Why SELECT must be adorned with REF CURSOR to work?

hello
*"PLS-00428: an INTO clause is expected in this SELECT statement"* - This problem has been resolved. I just want to understand WHY SELECT statements need to be paired with REF CURSOR.
          To reproduce this,
               DECLARE
                    Id1 numeric(19,0);
                    Id2 numeric(19,0);
                    CreateTimestamp date;
               BEGIN
               -- ATTN: You'd either need to select into variable or open cursor!
               select * from SystemUser left join Person on Person.Id = SystemUser.PersonId WHERE Person.PrimaryEmail in ('[email protected]','[email protected]');
               END;
          Solution?
               * In install script:
                    CREATE OR REPLACE PACKAGE types
                    AS
                         TYPE cursorType IS REF CURSOR;
                    END;
               * Then in your query:
                    DECLARE
                         Id1 numeric(19,0);
                         Id2 numeric(19,0);
                         Result_cursor types.cursorType;
                    BEGIN
                    OPEN Result_cursor FOR select * from SystemUser left join Person on Person.Id = SystemUser.PersonId WHERE Person.PrimaryEmail in ('[email protected]','[email protected]');
                    END;
I Googled for reasonable explaination - closest is: http://www.tek-tips.com/viewthread.cfm?qid=1338078&page=34
That in oracle block or procedures are expected to do something and a simple SELECT is not!! (Very counter intuitive). What needs to be done is therefore to put the select output into a ref-cursor to fool oracle so that it thinks the procedure/block is actually doing something. Is this explanation right? Sounds more like an assertion than actually explaining...
Any suggestion please? Thanks!

Opening a cursor (ref cursor or otherwise) is not the same as executing a select statement.
A select statement returns data, so if you are using it inside PL/SQL code it has to return that data into something i.e. a local variable or structure. You can't just select without a place for the data to go.
Opening a cursor issues the query against the database and provides a pointer (the ref cursor), but at that point, no data has been retrieved. The pointer can then be used or passed to some other procedure or code etc. so that it may then fetch the data into a variable or structure as required.
It's not counter-intuitive at all. It's very intuitive.
