Fetch API cursor

Hi,
The sql service is reporting the following query running more 100k execution per minutes- fetch api_cursor 000000018.
How can I diagnose, which queries are being requested from my database.
i tried executing the following query:
SELECT c.session_id, c.properties, c.creation_time, c.is_open, t.text
FROM sys.dm_exec_cursors (53) c
CROSS APPLY sys.dm_exec_sql_text (c.sql_handle) t
I get the following response error from sql - The user does not have permission to perform this action.
any further guide would be very helpful. Thanks

To use dm_exec_sql_text you need VIEW SERVER STATE permissions.
See http://msdn.microsoft.com/en-us/library/ms181929.aspx?ppud=4
Even if you are thinking to use DBCC inputbuffer
Permissions default to members of the sysadmin fixed server role only, who can see any SPID. Other users can see any SPID they own.

Hi alma,
Plz u dnt wrt babytalk rr SMS-language -> mi! Becoz mi don lejk dat.
I suppose that your data block "forecast_result" are based on the table of the same name. Otherwise this may be the cause of some of your trouble.
Your code would properly work better like this:

Fetch next cursor/ invalid database interruption

Hi Experts,
I would appreciate your help for the following problem:
I am trying to develope something like that:
OPEN CURSOR ... WITH HOLD
loop at ...
         FETCH ... PACKAGE SIZE ... into lt_names
         insert table ZZ_XXXX ... from lt_names
         commit work
endloop.
in the second loop, the FETCH dumps raising the runtime error "Invalid interruption of a database selection"
Runtime Error          DBIF_RSQL_INVALID_CURSOR
Exception              CX_SY_OPEN_SQL_DB
The cursor is opened "with hold".
Does anybody know, why does it dump?
Cheers
marmsg

Hi Thomas,
I have four entires in a custom z-table. During FETCH Statements, I use, PACKET SIZE, of 2.
Rough code is as follows:
OPEN CURSOR WITH HOLD w_dbcur1 FOR
SELECT * FROM ztable.
WHILE sy-subrc = 0.
FETCH NEXT CURSOR w_dbcur1 INTO TABLE i_notes PACKAGE SIZE p_pack. "Here packet size is of 2
IF sy-subrc = 0.
Calling some X BAPI Function module.
Calling BAPI_TRANSACTION_COMMIT Function module.
ENDIF.
ENDWHILE.
CLOSE CURSOR w_dbcur1.
Here the problem is, if I give packet size as 30,000, then program is working fine. If I am giving packet size as 2, which less than 4 entries in the table, The program dumps either at first execution of FETCH NEXT CURSOR statement or at the second time of FETCH NEXT CURSOR. Can you provide exact solution for this, and not the links please. Rewards will be provided.
Thanks,
Vijayanand.

Fetch Next Cursor Short Dumps

Hello All,
 I have the following code which short dumps after losing its cursor position.
OPEN CURSOR WITH HOLD dbcur FOR
 select * from ekpo where bukrs in s_bukrs2.
 do.
 FETCH NEXT CURSOR dbcur INTO table iekpo package size pkgsize.
 if sy-subrc <> 0.
 close cursor dbcur.
 exit.
 else.
 perform ouput_to_text_file.
 refresh: iekpo.
 endif.
 enddo.
I have millions of records to be extracted and simple select to an internal table causes memory problems. Thus I need to extract a chunk of records write them to a text file, then get the next chunk.
Any suggestions?
Thank you,
Jerry

GUI Download probably causes problem, writing to a dataset on app server might not cause the problem, maybe you want to try.
Regarding the select, here is some pseudo code outlining what I mean:
clear wa_ekpo.
do.
select * from ekpo into table lt_ekpo up to 10,000 rows
 where ebeln > wa_ekpo-ebeln or ( ebeln = wa_ekpo-ebeln and ebelp > wa_ekpo-ebelp )
 order by primary key.
if sy-subrc ne 0.
 exit.
endif.
download lt_ekpo (appending to existing file)
l_lines = lines( lt_ekpo ).
read table lt_ekpo into wa_ekpo index l_lines.
enddo.
Will run for a while, but should not dump out

Fetching from cursor

Hello all.
How can i enforce the sql+ start fetching first cursor field by
one field intervals?
My sql+ starts fetch from the second item by 2 records intervals,
so the 4th record is the next one to fetched after the second.
best regards
yosi sarid.

Hi,
could you please show us the where clause of the cursor?
I think you are missing something.
Another fault in your Code is the x_commit_count.
You increment it every time, but you never set it to zero again. So after 100 inserts, it commits after each loopstep.
Is this what you want???
DECLARE
CURSOR c_cursor IS SELECT * FROM TABLE_A@REMOTE, TABLE_B@REMOTE WHERE...
x_commit_count NUMBER := 0;
BEGIN
FOR r_record IN c_cursor LOOP
INSERT INTO LOCAL_TABLE;
x_commit_count := x_commit_count + 1;
IF x_commit_count >= 100 THEN
COMMIT;
ELSE
NULL;
END IF;
END LOOP;
END;

RE: (forte-users) Optimal number of records to fetch fromForte Cursor

Guys,
The behavior (1 fetch of 20000 vs 2 fetches of 10000 each) may also be DBMS
related. There is potentially high overhead in opening a cursor and initially
fetching the result table. I know this covers a great deal DBMS technology
territory here but one explanation is that the same physical pages may have to
be read twice when performing the query in 2 fetches as compared to doing it in
one shot. Physical IO is perhaps the most expensive (vis a vis- resources)
part of a query. Just a thought.

Subject: RE: (forte-users) Optimal number of records to fetch from Forte C
ursor
The reason why a single fetch of 20.000 records performs less then
2 fetches of 10.000 might be related to memory behaviour. Do you
keep the first 10.000 records in memory when you fetch the next
10.000? If not, then a single fetch of 20.000 records requires more
memory then 2 fetches of 10.000. You might have some extra over-
head of Forte requesting additional memory from the OS, garbage
collections just before every request for memory and maybe even
the OS swapping some memory pages to disk.
This behaviour can be controlled by modifying the Minimum memory
and Maximum memory of the partition, as well as the memory chunk
size Forte uses to increment its memory.
Upon partition startup, Forte requests the Minimum memory from the
OS. Whithin this area, the actual memory being used grows, until
it hits the ceiling of this space. This is when the garbage collector
kicks in and removes all unreferenced objects. If this does not suffice
to store the additional data, Forte requests 1 additional chunk of a
predefined size. Now, the same behaviour is repeated in this, slightly
larger piece of memory. Actual memory keeps growing until it hits
the ceiling, upon which the garbage collector removes all unrefer-
enced objects. If the garbage collector reduces the amount of
memory being used to below the original Miminum memory, Forte
will NOT return the additional chunk of memory to the OS. If the
garbage collector fails to free enough memory to store the new data,
Forte will request an additional chunk of memory. This process is
repeated untill the Maximum memory is reached. If the garbage
collector fails to free enough memory at this point, the process
terminates gracelessly (which is what happens sooner or later when
you have a memory leak; something most Forte developpers have
seen once or twice).

Subject: (forte-users) Optimal number of records to fetch from Forte
Cursor
Hello everybody:
I 'd like to ask a very important question.
I opened Forte cursor with approx 1.2 million records, and now I am trying
to figure out the number of records per fetch to obtain
the acceptable performance.
To my surprise, fetching 100 records at once gave me approx 15 percent
performance gain only in comparsion
with fetching records each by each.
I haven't found significant difference in performance fetching 100, 500
or
10.000 records at once.In the same time, fetching 20.000
records at once make a performance approx 20% worse( this fact I cannot
explain).
Does anybody have any experience in how to improve performance fetching
from
Forte cursor with big number of rows ?
Thank you in advance

Hi Kieran,
According to your description, you are going to figure out what is the optimal number of records per partition, right? As per my understanding, this number was change by your hardware. The better hardware you have, the more number of records per partition.
The earlier version of the performance guide for SQL Server 2005 Analysis Services Performance Guide stated this:
"In general, the number of records per partition should not exceed 20 million. In addition, the size of a partition should not exceed 250 MB."
Besides, the number of records is not the primary concern here. Rather, the main criterion is manageability and processing performance. Partitions can be processed in parallel, so the more there are the more can be processed at once. However, the more partitions
you have the more things you have to manage. Here is some links which describe the partition optimization

Fetch From Cursor

In my Procedure I want to explicitly open the cursor and fetch from the cursor and again close the cursor
I don’t want to use like this for some testingsomething:
Create procedure kk
Cur out sys_refcursor
As
Open cur for
Select * from table;
End
I need to use like this
Create procedure kk
Cursor c is select * from table; need to return this cursor.
As
How to return that cursor
Thanks

maybe something like:
create or replace procedure get_emp_name as
cursor c1 is
    select * from emp;
vEname emp.ename%type;
begin
open c1;
fetch c1 into vEname;
if c1%notfound then
     exit;
end if;
close c1;
end;
/or
Create procedure get_emp_name as
Cursor c1 is
   select *
     from emp;
begin
for c1_rec in c1 loop
     dbms_output.put_line('Emp Name: '||c1_rec.ename);
end loop;
end;

Fetch from cursor when no records returned

Hi,
I've got the following question / problem?
When I do a fetch from a cursor in my for loop and the cursor returns no record my variable 'r_item' keeps the value of the previous fetched record. Shouldn't it contain null if no record is found and I do a fetch after I closed and opend the cursor? Is there a way the clear the variable before each fetch?
Below you find an example code
CURSOR c_item (itm_id NUMBER) IS
SELECT DISTINCT col1 from table1
WHERE id = itm_id;
r_item c_item%ROWTYPE;
FOR r_get_items IN c_get_items LOOP
IF r_get_items.ENABLE = 'N' THEN
      open c_item(r_get_items.ITMID);
      fetch c_item into r_item;
      close c_item;
      IF r_item.ACCES = 'E' then
           action1
      ELSE
           action2
      END IF;
END IF;
END LOOP; Thanx

OPEN pcursor FOR
SELECT column1,
 column2,
 CURSOR (SELECT column1, column2
 FROM table2
 WHERE <some clauses come here>) icursor1
 FROM table1
 WHERE <some clauses come here>;In a PL/SQL block I would like to execute proc1 and then to fetch from pcursor. This is what I am doing so far:
DECLARE
ldata SYS_REFCURSOR;
larg1 NUMBER := 123;
larg2 NUMBER := 456;
outcolumn1 dbms_sql.Number_Table;
outcolumn2 dbms_sql.Number_Table;
BEGIN
some_package_name.proc1 (ldata, larg1, larg2, ...);
FETCH ldata BULK COLLECT INTO
 outcolumn1, outcolumn2,..., *and here is my problem*;
END;
/How can I rewrite this in order to get the content of icursor1 ?
Thanks a lot!

Firstly ref cursors contain no data they are not result sets but pointers to compiled SQL statements.
Re: OPEN cursor for large query
PL/SQL 101 : Understanding Ref Cursors
Ref cursors are not supposed to be used within PL/SQL or SQL for that matter, though people keep on insisting on doing this for some reason.
http://download.oracle.com/docs/cd/E11882_01/appdev.112/e10472/static.htm#CIHCJBJJ
Purpose of Cursor Variables
You use cursor variables to pass query result sets between PL/SQL stored subprograms and their clients. This is possible because PL/SQL and its clients share a pointer to the work area where the result set is stored.A ref cursor is supposed to be passed back to a procedural client language, such as Java or .Net.
If you want to re-use a SQL statement in multiple other PL/SQL or SQL statements you would use a view.

Different error messages from different env while fetching ref cursor

Hi 
I have a package where i need to call one of the procedure.I this 
procedure i am returning a refcursor as out parameter.Before returning refcursor i 
am doing i am checking a condition if it is satisfied then I am saying return or else 
it will proceed and refcursor is assigned for out parameter.So i am speakig about 
the condition where i am exiting from procedure before refcursor parameter is 
assigned .And later i am tring to fetch from that cursor .So i am getting different 
kinds of errors which i described as follows 
 
 
So If execute that procedure from sqlplus uing 
 
 
var m ref cursor 
DECLARE 
Y NUMBER; 
Z NUMBER; 
A NUMBER; 
BEGIN 
A:=campa.dtl_inq(2,100070875,'R',Y,Z,:M); 
END; 
 
Then if say 
Print m 
It gives 
 
ORA-24338: statement handle not executed 
 
And if i execute this using vb application 
 
I am getting following error 
 
ORA-01023: Cursor context not found (Invalid cursor number) 
 
So i am serching the reason for different errors 
 
Regards 
vamsi krishna 

The error depends on exactly what OCI calls the client software makes in accessing this invalid (null) ref cursor variable.
It would seem that SQL*Plus makes different calls than what your code and Visual Basic does - thus the different error messages returned by the two applications.

SAVE EXCEPTIONS when fetching from cursors by BULK COLLECT possible?

Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit Production
Hello,
I'm using an Cursor's FETCH by BULK COLLECT INTO mydata...
Is it possible to SAVE EXCEPTIONS like with FORALL? Or is there any other possibility to handle exceptions during bulk-fetches?
Regards,
Martin

The cursor's SELECT-statement uses TO_DATE(juldat,'J')-function (for converting an julian date value to DATE), but some rows contain an invalid juldat-value (leading to ORA-01854).
I want to handle this "rows' exceptions" like in FORALL.
But it could also be any other (non-Oracle/self-made) function within "any" BULK instruction raising (un)wanted exceptions... how can I handle these ones?
Martin

Hello All,
If i open a cursor once can i fetch the elements of a cursor n times like above? i see only either one of those procedures are printing the details but not both.
Wonder why as i am passing the same ref cursor to a second procedure.
It's neither throwing me an error saying the elements of ref cursor are already fetched.
Thank you.

You can't see any such thing. That code above won't even compile let alone run.
The 'ref cursor' you are talking about is defined in a standalone procedure 'refcursor1' which does NOTHING but declare some variables that are then NEVER USED.
The other procedures try to use variables that DO NOT EXIST since they are not declared in the procedure that is trying to use them. So those procedures won't compile and even if they did compile and run each execution only does ONE fetch so the anonymous block can't possibly produce multiple rows of output.
I don't know what you claim to be seeing but it certainly isn't anything produced by the code you posted.

NLS Error on Second Fetch from Cursor

Oracle 8i using PRO*C
We have a UNIX (HP) environment (operational account) in which the NLS_LANG was not set for the shell. One of our applications opened a cursor for update and performed its first fetch. After processing it went back to fetch an additional buffer. At this point, the application failed with the following error: "SQLCODE: ORA-01890: NLS error detected". When we set the NLS_LANG enviroment variable this error disappeared.
I need to know what the NLS_LANG enviroment variable is doing and why it is causing the second fetch to fail when it is not set so I can argue with the powers that be to have this paremeter always set for this accounts shell (i.e. globally). No-one really knows what this does here or why it would cause the cursor to fail, and so they are telling us to just set the variable in our own applications shell.
I know the real answer to this is to set it up for the operational (global) shell but...
Thanks in advance,
Bill Rosmus

it is difficult. The main problem is that you can't be sure that the function is called only once for each row.
Why don't you simply run the cursor and the function separatly in pl/sql.
CURSOR myCur IS SELECT myTable1.* FROM myTable1 ;
SUBTYPE myRecType IS myCur%ROWTYPE ;
funcResult varchar2(100); /* use the correct return datatype from your function here */
FOR myRec in myCur LOOP
 BEGIN
 funcResult := myPackage.myFunc(myRec.column1);
 EXCEPTION
 WHEN myPackage.myFunc_Exception THEN
 <... do anything when fetched but function myFunc raised this exception ...>
 END ;
 <...do anything with row currently fetched>
 END LOOP;You even have more control where to handle the exception. Also there is one pl/sql context switch less. Since the function itself is pl/sql it could even be faster to run it in pl/sql then to call it from sql (inside a select).
