Report based on Ref Cursor and lock package/table (ORA-04021)

Hi,
I have reports based on Ref Cursor. Report builder and Reports Background Engine make pins for package, which consist of Ref Cursor, and for tables, which is used in package. So I can't grant any privileges on these tables anybody.
For example, after next statement:
GRANT SELECT ON table_name TO user_name
I received the next error:
ORA-04021: timeout occurred while waiting to lock object table_name
Thanks

And if I run the same thing on 10g -- all goes conversely. The first part runs ok, and the second
part reports "ORA-01006: bind variable does not exist" (as it should be, I think). Remember, there
is ONE bind variable in sql, not two. Is it a bug in 8i?
What should we do to avoid this error running the same plsql program code on different Oracle

P.S. Thank you for your invaluable work on this site.

what is the purpose of this query really?
but it would appear to be a bug in 8i (since it should need but one). You will have to work that

Ref cursor and dynamic sql

Hi..
I'm using a ref cursor query to fetch data for a report and works just fine. However i need to use dynamic sql in the query because the columns used in the where condition and for some calculations may change dynamically according to user input from the form that launches the report..
Ideally the query should look like this:
select
a,b,c
from table
where :x = something
and :y = something
and (abs(:x/:y........)
The user should be able to switch between :x and :y
Is there a way to embed dynamic sql in a ref cursor query in Reports 6i?

Hello Nicola,
You can parameterize your ref cursor by putting the query's select statement in a procedure/function (defined in your report, or in the database), and populating it based on arguments accepted by the procedure.
For example, the following procedure accepts a strongly typed ref cursor and populates it with emp table data based on the value of the 'mydept' input parameter:
Procedure emp_refcursor(emp_data IN OUT emp_rc, mydept number) as
Begin
-- Open emp_data for select all columns from emp where deptno = mydept;
Open emp_data for select * from emp where deptno = mydept;
End;
This procedure/function can then be called from the ref cursor query program unit defined in your report's data model, to return the filled ref cursor to Reports.
Thanks,

How to divide resultset of a query in different ref cursors in a package

Hi Oracle Gurus,
I need to create a package which counts the no of rows returned by a select query on multiple tables and according to the returned rowcount inputs the resultset in a ref cursor. Procedure will be called by a .NET program and output param refcursor will be assigned to a data reader which will redirect all the data to an Excel file.
All the above is done. Issue is due to Excel's limit of 64000 rows, if data returned by query is greater than 64K it wont be fit in 1 Excel sheet. So, in order to overcome this limit I need to do some looping in Oracle package which keeps on storing the query results (rows<64K) in different ref cursors so that these refcursors as OUT params can be redirected to separate Excel sheets in C# program.
NOTE : Earlier on I created 2 procedures in the package to fetch rows<64K and another one to fetch rows between 64K and rowcount of the query. My program was calling 2 different procedures to redirect data into 2 diff Excel sheets.
But this fails when query resultset is even greater than 128000 or more and demands 3-4 or even more Excel sheets to be created.
Please help.
Any idea how to do looping in Oracle to accomplish this?

> So, in order to overcome this limit I need to do some looping in Oracle package which keeps on

Huh?
That is saying that "I need to change this road and build it straight through that lake as the road has a curve here".
It surely is a LOT easier to leave the road as is and simply turn the darn steering wheel in the car?
Have the .Net data reader keep a row count of rows read from the ref cursor - and when it reached a pre-set max, have the reader do a "control break"[1] and change to a new worksheet as the destination for writing the rows to.
[1] Google the term if you do not understand this basic concept that was among the very basic program control structures taught back in the 80's.. while I foam at the mouth how today's "wonder kids" turned programmers, that grew up with computers, do not even comprehend the most basic programming logic designs...

Ref Cursor and For Loop

The query below will return values in the form of
bu     seq     eligible
22     2345     Y
22     2345     N
22     1288     N
22     1458     Y
22     1458     N
22     1234     Y
22     1333     N
What I am trying to accomplish is to loop through the records returned.
for each seq if there is a 'N' in the eligible column return no record for that seq
eg seq 2345 has 'Y' and 'N' thus no record should be returned.
seq 1234 has only a 'Y' then return the record
seq 1333 has 'N' so return no record.
How would I accomplish this with a ref Cursor and pass the values to the front end application.

One remark why you should not use the assignment between ref cursor
variables.
(I remembered I saw already such thing in your code).
Technically you can do it but it does not make sense and it can confuse your results.
In the opposite to usual variables, when your assignment copies value
from one variable to another, cursor variables are pointers to the memory.
Because of this when you assign one cursor variable to another you just
duplicate memory pointers. You don't copy result sets. What you do for
one pointer is that you do for another and vice versa. They are the same.
I think the below example is self-explained:
SQL> /* usual variables */
SQL> declare
2   a number;
3   b number;
4 begin
5   a := 1;
6   b := a;
7   a := a + 1;
8   dbms_output.put_line('a = ' || a);
9   dbms_output.put_line('b = ' || b);
10 end;

Restrict access in report based on compnay codes and cost centers

Hi,
We are using a standard report, which is assigend to a Z transaction and assigend to the role.
The report need to be restricted based on the company code and cost center ?
but i could not find any AUTHORITY- CHECK statements in the code ( there is only authority check statement for object G_803J_GJB which has authorization groups and aCTVT field.)
Please let me know what steps need to be followed to restrict the report based on company codes and cost centers.
Thanks for your help in advance.

Thanks all for the quick response.
Steps to be followed:
1) incorporatomg AUTHORITY-CHECK statements for K_KOSTL and F_BKPF_BUK objects in the program.
2) adding the objects as check yes in SU24 for the Z transaction.
and restricting in the role.
The program name is "GP3O4ZGOOF3HA68QMGHF8S7I9ER250".
Please let me know if any more steps need to be followed.
Based on this i have to send a estimate to my client.
Thanks,
Sanketh.

Ref cursors and dynamic sql..

I want to be able to use a fuction that will dynamically create a SQL statement and then open a cursor based on that SQL statement and return a ref to that cursor. To achieve that, I am trying to build the sql statement in a varchar2 variable and using that variable to open the ref cursor as in,
open l_stmt for refcurType;
where refcurType is a strong ref cursor. I am unable to do so because I get an error indication that I can not use strong ref cursor type. But, if I can not use a strong ref cursor, I will not be able to use it to build the report based on the ref cursor because Reports 9i requires strong ref cursors to be used. Does that mean I can not use dynamic sql with Reports 9i ref cursors? Else, how I can do that? Any documentation available?

Philipp,
Thank you for your reply. My requirement is that, sometimes I need to construct a whole query based on some input, and sometimes not. But the output record set would be same and the layout would be more or less same. I thought ref cursor would be ideal. Ofcourse, I could do this without dynamic SQL by writing the SQL multiple times if needed. But, I think dynamic SQL is a proper candidate for this case. Your suggestion to use lexical variable is indeed a good alternative. In effect, if needed, I could generate an entire SQL statement and place in some place holder (like &stmt) and use it as a static SQL query in my data model. In that case, why would one ever need ref cursor in reports? Is one more efficient over the other? My guess is, in the lexical variable case, part of the processing (like parsing) is done on the app server while in a function based ref cursor, the entire process takes place in the DB server and there is probably a better chance for re-use(?)
Thanks,
Murali.

Reports 3.0, Ref Cursor from stored procedure

I have a problem trying to use Ref Cursor as datasource (i.e.
Ref Cursor Query) in Reports 3.0
I have created a stored package with a function which returns
Ref Cursor.
That function just opens the cursor and returns it to the
calling module.
Reports recognizes returned cursor - it creates a group for that
query, with all columns, than I built
a layout model - everything is OK on that stage.
During the execution of that report (from previewer or using
Reports Runtime) I got an error message like that:
REP-0065 Virtual Memory System Error
REP-0200 Cannot allocate enough memory cavaa22
Error's description does not correspond the reality :) - there
is enough virtual & physical memory according to
Task Manager information.
So, that does not work when this package is stored one.
When I create the package on the client side - in Reports -
everything works just fine.
Cursor is opened with a very simple query, selecting records
from the very simple table having only one record.
There is no code written which closes that cursor or fetches the
records.
Client platform: WinNT 4.0 SP3
Oracle Reports: 3.0.5.8.0
Oracle Server: Oracle8 8.0.5.0.0 (and I tried also on Oracle7
7.3.4.3.0)
Thanx.

Sara,
GTT (Global Temporary Tables) in Oracle work a different way compared to SQL Server and Informix. There you can create temporary tables on the fly and drop them on the fly.
Here you should (note, you don't have to, but, best practice says that you should) create the table using the syntax...
create global temporary table.....
Once you create it, even though it looks like persistent table, it's not. It will have it's own individual data PER SESSION . You have two types of GTTs:
ON COMMIT PRESERVE ROWS and ON COMMIT DELETE ROWS (they work in slightly different way).
Look up GTTs here:

Dynamic queries in report builder 6i ( ref cursor query )

Hi everyone,
My requirement is that I want to create a report where the query is dynamic. The dynamic part will be known at runtime as it is being passed via a parameter. My query looks like this :
select * from emp where sal :p1 :p2
Possible values for :p1 are - '>', '<', '>=', '<=', '=', '!='
Possible values for :p2 are - any value entered by the user
I tried creating a query in report builder based on a ref cursor. But it does not allow me to create the query for the ref cursor dynamically. That means I have to hardcode the query in the program.
I tried using place holder columns without success.
Can someone please help me ?
Regards,
Al

Hi,
You can use lexical paramters in the sql query
x - char - parameter
select * from emp &x
you need to pass the value for x in the parameter as
'where sal < 1234'.
Note : Lexical variable should be of char datatype.
This is an alternative to the ref cursors.
This works. Hope this is clear.

Ref Cursor from PL/SQL Table

I'm building a complex report in which the information cames from a lot of tables and needs complex formatting. I'd like to base my report in a table returned by a stored procedure (like you can do in Forms). Is there any way to convert an PL/SQL table in a Ref Cursor?

Why don't you process the data in procedure and dump into temporary table. And base your report on that temporary table.
it may simplify your report.

Package timeout (ORA-04021)

Hi all,
I am trying to create a package but it throws out an error after long time (I guess 5 to 10 minutes), Any help will be greatly appreciated.
Error message is:
ERROR at line 1:
ORA-04021: timeout occurred while waiting to lock object
null

I had this problem once when I was trying to compile schema in the procedure.
So don't you have some similar problem?
Like the package is currently running or any funny code in the package?
What this does package do?
Maybe provide more information about the package.

Report based on two facts and dimensions

Hello All,
I have a report that comes from two facts say F1 and F2. There are certain conformed dimensions, and certain non conformed dimensions.
Now say Product is a conformed dimension.
Now these fact tables are at a very detail level and have millions of records.
I need a report with F1,F2 and product. F1 can have data for certain products and F2 can have certain products. Now to get all the data without dropping any product... I have done outer join. This is causing performance issue. Is there any other way... that I can design to avoid this...
Also what happens to prompts... if i have product and some other dimensions which are confirmed. It would go to only certain fact... and not pull data when the product doesn't have data for fact F1 and has data for F2. Is there any solutions for this?
Please help...
thanks,
deep

Hi deep,
You have did it right way,giving outer join fetches you all records....there is no other way to get this details.
Let all records be fetched.But take a prompt on product,so when user selects a particular product only the data of that product details are fetched and there wont be any performance issues.
hope helps you.
Cheers,

ORA-12714 error using NVARCHAR2, REF CURSOR and TABLE FUNCTION

Hello,
we have tested this simple script on all the following versions of Oracle: 9.2.0.3, 10.2.0.1.0 , 11.1.0.6.0 - but we got the same error in everyone of these.
CREATE OR REPLACE TYPE Rec_Prova IS OBJECT(
    Id INTEGER,
    NodeValue NVARCHAR2(50)
CREATE OR REPLACE TYPE Tab_Prova IS TABLE OF Rec_Prova;
DECLARE
    CurProva SYS_REFCURSOR;
    varTable Tab_Prova := Tab_Prova();
BEGIN
    OPEN CurProva FOR
        SELECT Id, NodeValue FROM TABLE(CAST(varTable AS Tab_Prova));
END;The error is: "ORA-12714: invalid national character set specified"
We know that changing the type of NodeValue from NVARCHAR2 to NCLOB it works, but the performances are very poor.
Therefore this solution is not acceptable for us.
We also know that if the character set of the database is set to unicode (NLS_NCHAR_CHARACTERSET = AL16UTF16) we can use the VARCHAR2 for store also the unicode characters and the problem is solved. But some of our customers can't change the settings of theirs databases... moreover, in this forum someone says:
"To all dba's who try to change the NLS_CHARACTERSET or NLS_NCHAR_CHARACTERSET by updating props$ . This is NOT supported and WILL corrupt your database. This is one of the best way's to destroy a complete dataset. Oracle Support will TRY to help you out of this but Oracle will NOT warrant that the data can be recoverd or recovered data is correct. Most likely you WILL be asked to do a FULL export and a COMPLETE rebuild of the database."
Is there any workaround except the two that I have mentioned?
Thank you in advance.

ORA-12714: invalid national character set specified
Cause: Only UTF8 and AL16UTF16 are allowed to be used as the national character set
Action: Ensure that the specified national character set is valid
So it looks like that you should change the character set or go for NCLOB (and if you're on version 11, maybe securefiles gives you the performance you want).

Component Qty Requirement report based on the period and vendor

Hi Guru's,
Good day!
I would like to get a report with output parameters finished product(FG), the requiremnts for that FG for given period(lets say month of march), customer for that FG, then componet material requiremnt for that FG in that period.
Input: component material( bought out), vendor, period
output required: FG's for given component material, requirement for that FG in thst period, vendor, requiremnt for componet material for this FG in that period, IF that component material used in two different FG then both details required with splitup.
we checked function modules but we were not able to find the FG by giving component material as input.
Is this possible to get the required output as required or is there any way to find the same.
kindly help if is there any function modules or BAPI's available.
let me know if you require any other information.
Thanks in advance.
Reagrds,
Anand

If you want such report viz in line with parameters of MD04; try for function module given below
MD_STOCK_REQUIREMENTS_LIST_API
This may help you as the output is dynamic unlike MD04. Check if it works
