Function with dynamics cursor.

Hi everybody,
I'm trying to write a function having as argument as SQL query(or a part of it). This SQL query should generate a cusror within the function. All the way would have the generated cusror always the same structure.
CREATE OR REPLACE FUNCTION Calcul_avg(Name_Table VARCHAR) RETURN NUMBER
IS
TYPE Funct_Cursor_Type IS REF CURSOR RETURN Defined_Table%ROWTYPE;
Funct_Cursor Funct_Cursor_Type;
OPEN Funct_Cursor
FOR SELECT ID, NAME FROM Name_Table ;
Return Calcul_avg;
With this function,
I'm getting the error:
PLS-00455: cursor 'FUNCT_CURSOR' cannot be used in dynamic SQL OPEN statement
Thanks for your help!!
Alex

The error message measn what it says. We cannot use a strongly typed cursor with dynamic SQL. This is because the typing is enforced at compile time, whereas the cursor is only assembled at runtime. So we must use weakly typed cursors in this situation.
If you have 9i then you can use an instance of the pre-defined SYS_REFCURSOR. Else
TYPE Funct_Cursor_Type IS REF CURSOR;Cheers, APC

2 functions with one cursor or.. 1 function with 2 cursors?

Hi friends,
I hope you help me to decide is this easy question:
Actually I have 2 functions. Both are the same more or less: Both get data from USERS table. (In the users table there are several columns, I'm interested in "code" and "description")
Function1 have a cursor which obtain data and orders by code,
Function2 have a cursor which obtain data and orders by description.
That's the only difference.
I want to "optimize" the code so I was thinking on creating only a function.
To do the same in one only function I thinked on passing a parameter i.e.: p_ordertype to know which would be the order ("C" for code or "D" for description)
In that function I would have two cursors and I would ask for the parameter to execute one "FOR...." or the other.
The question: Would it be really effective? I think that if I have 2 cursors in a function... I would cosume more memory than if I would only have one cursor.. (because I think data selected from cursors is parsed to memory when you invoke the function, before the 1st instruction after the BEGIN is executed, isn't it?)
Would it be better 2 functions with one cursor each one or... one function with 2 cursors?
Thanks in advance for your opinions.
Jose.

Hi again Todd,
there's a problem with you solution :
Imagine you have the following users:
usercode - userdescr
1 - ALAN
2 - RICHARD
3 - DANI
12 - CHARLIE
20 - BARRY
If we pass a 'C' as p_ordertype (to obtain the list like above, ordered by usercode) , the result would be:
1 - ALAN
12 - CHARLIE
2 - RICHARD
20 - BARRY
3 - DANI
Do you understand what i'm trying to explain?... I hope that... I tried with
ORDER BY DECODE(p_ordertype,'C',usercode,'D',TO_NUMBER(userdescr));
but it doesn't works...
More ideas?

Create function with a cursor in it

I need help to create a function called f_Getfeedesc. I want to use a cursor for Loop. The function will return fees description for any folder.
If a folder has more than one fee description, it will concatenate the fees description.
The select statement I have here returns the following fees description:
CO Residential 3+ Units No Entry Penalty Fee
C of O Initial Fee
CO Residential 3+ Units Initial Fee
However when the function is done if you run it using the folderrsn 99999 the result should look like this:
CO Residential 3+ Units No Entry Penalty Fee / C of O Initial Fee / CO Residential 3+ Units Initial Fee
If the folderrsn has only one fee description the result should just return that one fee description. e.g CO Residential 3+ Units No Entry Penalty Fee
I am using the following tables:
folder table with FOLDERRSN......... NOT NULL NUMBER(10,0) column.
accountbillfee table with FEECODE..........NOT NULL NUMBER(10,0) column.
validaccountfee table with FEECODE........NOT NULL NUMBER(10,0) and FEEDESC............NOT NULL VARCHAR2(80) columns.
SELECT DISTINCT vaf.feedesc
FROM folder f, accountbillfee abf, validaccountfee vaf
WHERE f.folderrsn = abf.folderrsn
AND vaf.feecode = abf.feecode
--And f.folderrsn = argfolderrsn
AND f.folderrsn = 99999 --for a specific folderrsn

Hi,
What you're trying to do is called "string aggregation".
There's an excellent page on AskTom with several general solutions.
I recommend the first one, STRAGG.
Once you have STRAGG installed, you can get the output you want as simply as this:
SELECT    feecode
,         STRAGG (feedesc)
FROM      validaccountfee
GROUP BY feecode;Edited by: Frank Kulash on Sep 13, 2008 2:56 AM

Running a function with a cursor output

Hi All,
It sounds like this should be easy, but I can't get it to work! I'm trying to run or debug a function in JDev. The function simply calls a Java SP that returns a cursor. This all works fine and it runs in SPL Plus with no problems. The problem is that when I try to run it from within JDev I get presented with the PL/SQL block window, and nothing I do will let me view the contents of the cursor returned - mostly I just get errors and the code doesn't run at all.
The default code it generates is:
DECLARE
v_Return NULL;
BEGIN
v_Return := ALISI.POC.POCCALLSP();
-- Modify the code to output the variable
-- DBMS_OUTPUT.PUT_LINE('v_Return = ' || v_Return);
END;
I think this should be modified to say:
DECLARE
v_Return Types.ref_cursor;
BEGIN
v_Return := ALISI.POC.POCCALLSP();
-- Modify the code to output the variable
DBMS_OUTPUT.PUT_LINE('v_Return = ' || v_Return);
END;
But the DBMS_OUTPUT.PUT_LINE is expecting a string, not a cursor, and nothing I've tried (I've tried so many things I can't begin to list them - or remember them) will work.
Can anyone point out the error in my ways? Is it anything to do with the fact that I'm using a function and not a procedure? As you can probably tell I'm new to all this!
Many thanks,
John.

With "simple" variables, we are able to display the output using DBMS_OUTPUT. For composite variables (PL/SQL tables, PL/SQL records, cursors, etc), there's no good way for us to directly display the result. DBMS_OUTPUT.PUT_LINE can only take a "String", or something that can be converted to it, and unlike Java, not everything implements a toString method. We would expect in such cases that the user modify the code as desired to output the data.
That being said, you are actually encountering a bug here. With most datatypes that we can't display directly, we generally get enough information that we generate code that at least compiles and runs. I've logged a bug (3124777) to track this.
(For what it's worth, I've tried this in 9.0.5, only to discover that the functionality has regressed a bit to be even less correct than in 9.0.3.)
After the bug is fixed the output should look like this:
DECLARE
v_Return Types.ref_cursor; -- assuming this is the name of your ref cursor type
BEGIN
v_Return := ALISI.POC.POCCALLSP();
-- Modify the code to output the variable
-- DBMS_OUTPUT.PUT_LINE('v_Return = ' || v_Return);
END;The user would then need to modify the part that displays the output. In this example, it might go something like this:
DECLARE
v_Return Types.ref_cursor; -- assuming this is the name of your ref cursor type
v_Record v_Return%ROWTYPE;
BEGIN
v_Return := ALISI.POC.POCCALLSP();
-- Modify the code to output the variable
LOOP
    FETCH v_Return INTO v_Record;
    EXIT WHEN v_Return%NOTFOUND;
    DBMS_OUTPUT.PUT_LINE (v_Record.employee_id || CHR(9) || v_Record.last_name
      || CHR(9) || v_Record.salary); -- replace with your field names
END LOOP;
END;I hope this helps!

BETWEEN FUNCTION WITH IN A DECODE FUNTION IN A CURSOR

The following below is my query..I have to get the hours,min and seconds from a 'yyyy-mm-dd-24hh.mi.ss' value and check if the time is between 12 am to 6 am , then write it with one value else write an another value..I am trying to use 'BETWEEN' function in decode function but i am getting error.....Can we use BETWEEN function with in decode function or is there any other way
set serveroutput on
declare
cursor cur_dte is select lst_upd_date from EMPLOYESS ;
begin
for i in cur_dte loop
DECODE (substr(trim(i.lst_upd_date),12)) ,between '00.00.00.0000' and '06.00.00.00.0000' ,101,102);
dbms_output.put_line(i.lst_upd_date);
end loop;
end

First of all. If you are in PL/SQL then CASE is just a more colmplex expression then IF THEN ELSE. I usually prefere If then else, but for some rare cases.
The other issue is that you convert a datetime value into a string. This is wrong. it opens up all possible kinds of cenversion bugs. Stay with date or timestamp as long as possible.
The solution depends a little upon the datatype of your lst_upd_date column.
Here is a pl/sql solution assuming it is DATE.
The TRUNC function can be used to reduce a datetime to a day or to an hour.
declare
   cursor cur_dte is select lst_upd_date from employees ;
begin
   for i in cur_dte loop
     if trunc(i.lst_upd_date,'HH') between trunc(i.lst_upd_date) and trunc(i.lst_upd_date)+6/24 then
        dbms_output.put_line(to_char(i.lst_upd_date,'DD-MON-YYYY HH24:MI:SS'));
     end if;
   end loop;
end;
/But a pure SQL solution is much better.
Here is how you implement it using CASE in SQL.
example using pure sql
select e.*,
        case when trunc(e.lst_upd_date,'HH')
               between trunc(e.lst_upd_date) and trunc(e.lst_upd_date)+6/24
        then 101
        else 102
        end as "early_morning_check"
from employees e;And if it is a timestamp column then you could use the EXTRACT function.
select e.*,
        case when to_number(extract(hour from e.lst_upd_date))
               between 0 and 6
        then 101
        else 102
        end as "early_morning_check"
from employees e;You might want to consider if date values like 06:45:00 should be included or not.

Parallel piplelined function not parallelizing with ref cursor

RDBMS 11.2.0.3
I have a function with the following signature

pipelined
parallel_enable ( partition p_source by any )

f.out_213     280399
f.out_230     286834
f.out_70     289549But when I use a refcursor, it does not run in parallel
declare
rc sys_refcursor;
begin
open rc for 'select /*+ parallel(i 4) */ c1||chr(9)||c2 from mytable i';

loop
    dbms_output.put_line(rec.file_name || chr(9) || rec.num_records );
end loop;
end;
f.out_914     1133016Is this an expected behavior or am I doing something wrong? How can I use the function when the client returns the SQL statement as a character string

How to create a procedure function with a return value of ref cursor?

Can anybody provide a sample about how to create a procedure function with a return value of REF CURSOR?
I heard if I can create a function to return a ref cursor, I can use VB to read its recordset.
Thanks a lot.

Will a new MotherBoard cure Blank Screen with blinking cursor?

Stuck with Blank Screen with blinking cursor; ESC key couldn’t bring up Startup Menu; OS is not loading
Product Name: HP G62 237 CA Notebook PC
Short description of the problems:
--- Press ESC key couldn’t bring up Startup Menu when booting up
--- Blank screen with blinking cursor thereafter
--- Stuck here forever and OS is not loading
DETAILED INFORMATION:

System BOARD ID: 1484
Product #: WQ767UA#ABC
Product Config ID: 049C110000202710000020000
Problem History:
--- Used to have frequent BSOD (got fixed later because of faulty RAM that I suspected)
--- Window couldn’t be loaded
--- Window Repair and HP Recovery were tried but not functioning
--- OEM Hard Drive was then removed & formatted few times by using other computer
--- Hard Drive was then tested by other computer; it can be installed Win XP & Win 7
--- So, Hard Drive was eliminated from the suspect list
--- Replaced with other good RAM from other computers & put back the OEM Hard Drive to my HP G62; everything worked fine, such as: able to reinstall Win 7; listening to music files; got Internet to download latest BIOS from HP support site; connected to my 42 inched TV as my monitor; and even smoothly updated the BIOS from v.17 to v.37!
--- Also, able to receive Window Updates from the Internet; and seemed that all problems were nicely solved
--- Once I believe my system got stabilized; I went back to test the 2 supposedly problematic RAM to see whether they were both faulty or not, then the whole thing has turned around! Completely screwed me up until this moment …
--- After put back the problematic RAM, Window couldn’t be loaded …
--- With a few error messages… such as,
--- The file is possibly corrupt. The file header checksum does not match the computed checksum;
--- After the next reboot… an unexpected screen message showed up:

--- After that, OS was not loading …
--- Press ESC key couldn’t bring up the Startup Menu during boot up
--- Blank screen with blinking cursor thereafter and seems stuck here forever
Procedures performed for troubleshooting:
Tried hard reset for more than 5 times (removed battery, AC adapter disconnected and then hold down the Power button for more than 60 secs) and tried reseating memory too; same result with Blank Screen with blinking cursor after each reboot.
Connected to an external monitor [Fn + F4/F5] to see whether there was any display, nothing has showed on the external monitor, it seemed that no connection established between the two.
Finally, took the long journey to follow the Service and Maintenance Guide of HP G62 to remove the CMOS battery for well over 15 minutes and put it back. But the result was again disappointed. Tried 4 times already. The latest error message is:
The CMOS checksum is invalid. The CMOS will be reset to the default configuration and will be rebooted. Please check your BIOS Setup options to see if they change.
CMOS Reset (502)
ENTER – Reboot the system
After this message, the same Blank Screen with blinking cursor came back. And pressing the ESC key couldn’t bring up Startup Menu when booting up …
Note: the fan is still running; the Power button is functioning but seems stuck here forever!
I’ve already carefully read this HP Support document titled “HP BIOS Application Selected is Corrupt or Missing”:
http://h10010.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&dlc=en&docname=c01443485#N144
If really is the BIOS problems, then I will have the difficulties of updating a Window-based BIOS when I couldn’t even load Window!
(Note: Boot from USB has no point because right now I couldn’t change the boot sequence because the various “Startup Menu” options are not showing up!)
Secondly, I am still stuck with the Blank Screen with a blinking cursor after I passed the first screen of “Press the ESC key for Startup Menu” when re-booted again!
Thirdly, I have formatted my Hard Drive more than 3 times during the last few days for testing; I don’t have the OEM pre-loaded Win 7 with me anyone … and I don’t think I have the UEFI installed previously on my system. I did try hold down the Win Key + B with the most updated BIOS in the attached USB …, it came back with the same blank screen with a cursor blinking after reboot.
Note: the Blank Screen I’m experiencing right now is not completely black, in fact, there is background light from behind the screen and on each reboot, I can see the HP logo and the left corner message of: “Press ESC key for Startup Menu” … So, I suppose that my computer screen is not physically broken at least.
Requests:
Please explain to me that what are the problem areas and the root causes if is possible?
What steps or other tests can be done to make it work again?
Do you think replacing the entire MotherBoard can cure the Blank Screen with blinking cursor?
[Warranty: expired! I am the original purchaser & the end-user of this HP G62; acquired 2 years ago directly from a trustworthy source: staples (in Canada). Would HP Support still willing to service it for an extra charge?]
Thanks in advance for any suggestion and idea!

In mail, I am having trouble with my cursor. It doesn't "land" where I think I'm putting it. It usually "lands" somewhere below where I "click" it to be.

In Mail, I am having trouble with my cursor. When making revisions to what I have already typed, the cursor doesn't "land" where I "click" it to be. It seems to land somewhere below the spot I click on. It seems to have a mind of its own.

Database selection with Invalid Cursor error in RSDRI_INFOPROV_READ

Hi Everyone.
I am using RSDRI_INFOPROV_READ Function module for reading data from a multiprovider.
Logic of the code is as following
while <more data>
CALL RSDRI_INFOPROV_READ reading data in E_T_DATA
Append lines of E_T_DATA to EO_T_DATA.
If total lines of data in EO_T_DATA > 200000
<save EO_T_DATA in a file using GUI_DOWNLOAD>
<clear EO_T_DATA>
EndIF
EndWhile.
As soon as number of record exceed 200000 first file is saved, but after that next data call results in error.
Error says "Database selection with invalid cursor".
I suspect that this because of call to FM GUI_DOWNLOAD. While calling this FM after RSDRI_INFOPROV_READ causes system to commit and again the cursor is tried to open in next call casuing it to fail.
But it is imperative for me to save data in file at regular intervals as data volume is huge.
Any pointers in this direction will be helpful.

Pipelined Function with execute immediate

Hello Experts,
I have created a Pipe lined function with execute immediate, due to below requirement;
1) Columns in where clause is passed dynamically.
2) I want to know the data stored into above dynamic columns.
3) I want to use it in report, so I don't want to insert it into a table.
I have created a TYPE, then through execute immediate i have got the query and result of that query will be stored in TYPE.
But when calling the function i am getting
ORA-00932: inconsistent datatypes: expected - got -
Below is my function and type, let me know i am going wrong, and is my logic correct.

1) Columns in where clause is passed dynamically.No, that's something you've introduced, and is due to poor database design. You appear to have columns on your table called FPD1, FPD2 ... FPD31. The columns do not need to be 'passed dynamically'
2) I want to know the data stored into above dynamic columns.And you can know the data without it being dynamic.
3) I want to use it in report, so I don't want to insert it into a table.That's fine, though there's no reason to use a pipelined function.
You also have an pointless exception handler, which masks any real errors.
I'm not quite sure what the point of your "connect by" is in your query as we don't have your tables or data or know for sure what the expected output is.
However, in terms of handling the 'dynamic' part that you've introduced, then you would be looking at doing something along the following lines, using a static query that requires no poor dynamic code, and no pipelined function...

ESQL/C: Difficulties with DECLARE CURSOR and nested FROM CLAUSE

Hello @All,
i am trying to migrate an old esql-c-Application to Oracle 11g (on 64-Bit-AIX 7.1 - Platform)
PreCompiling is OK, but during runtime the following DECLARE - Statement returns ORA-01001: invalid cursor :
EXEC SQL
DECLARE cur_xyz CURSOR FOR
SELECT vPE, mPE, mZW, COUNT (*)
FROM ( SELECT v.K_PE AS vPE, m.K_PE AS mPE, m.ZW AS mZW, v.VKG
FROM ( SELECT K_NR, K_PE, u3.VKG, POS
FROM u3, r
WHERE u3.K_NR = '999999'
AND u3.LANG = 'F'
AND SUBSTR (PRTCTRL, 5, 1) > '0'
AND u3.VKG = r.VKG ( + )
) v, m
WHERE
v.K_NR = m.K_NR ( + )
AND v.K_PE = m.K_PE ( + )
AND POS is Null
) X
WHERE not EXISTS (SELECT VKG FROM NP WHERE X.VKG = NP.VKG )
GROUP BY vPE, mPE, mZW
ORDER BY vPE
When I run this statement without "EXEC SQL DECLARE cur_xyz CURSOR FOR" in SQL-Developer, there is no problem.
What is my fault? I hope, that I don't have to redesign this.
Thx in advance for anyonce help.

Hey Billy,
I work in a C/C++-Environment under AIX. I allready build a library with with more than x.000 Functions with ESQL-Statements.
Most of them are running.
If I need a CURSOR, I allways use constructs like this:
EXEC SQL DECLARE CursorName [SCROLL]CURSOR FOR
SELECT ...
if (SQLC == 0) {
EXEC SQL OPEN CursorName;
while (SQLC == 0) {
EXEC SQL FETCH ... CursorName INTO :<Structure or Fieldlist>;
EXEC SQL CLOSE CursorName;
At the Moment, I don't work with a cursor-variable in the DECLARE-Section.
In the case i discribed above, it is the first, where the ORA-01001 occurs.
Is it necessary to work with SQL_CURSOR - Variable in all or in special cases?
Thx 4 answers.

Problem with fetch cursor statement

Hi,
I am using FETCH CURSOR statement to fetch the data from a database table with package size. For the fetched records I am doing parallel processing using parallel processing frame work in banking system.
Here the problem is for the first iteration it works fine but when it comes to FETCH NEXT CURSOR in the second iteration , programs gets dumping by saying that 'CURSOR already closed'.
I am not closing the cursor in the program but some how it got closed some where in the standard function module which I used for parallel processing.
I used WITHHOLD also along with FETCH CURSOR but no use. Please let me know how to avoid the cursor to get close.
Below is my code
IF NOT l_tab_product IS INITIAL.
    OPEN CURSOR WITH HOLD lv_cursor FOR
     SELECT contract_int prodint cn_currency mig_grp
          INTO TABLE gt_cont
            FROM bca_contract
            FOR ALL ENTRIES IN l_tab_product
            WHERE prodint = l_tab_product-prodint
            AND   mig_grp IN s_migrp.
    DO.
      FETCH NEXT CURSOR lv_cursor
                        INTO TABLE gt_cont
                             PACKAGE SIZE lv_size.
      IF sy-subrc <> 0.
        CLOSE CURSOR lv_cursor.
        EXIT.
      ELSE.
parallel processing logic
ENDDO.
ENDIF.

Using Withhold will not make sure that the cursor will not get closed because of commits.
SAP Doc says
If the addition WITH HOLD is specified, the database cursor is not closed by a database commit executed using Native SQL. The addition does not have an influence, however, on implicit database commits or on any rollbacks which always close the database cursor.
You have to check the part written in your parallel processing logic.
As Brad said please donot dump your old threads like this.

Function with dynamics cursor.
