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

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

How to fetch n records at a time from a FM and then fetch next n records

I have a report program which is calling a function module . This function module returns all the records from a table. As the table has millions of records, it cant be returned at a time. How can we return N records from a function module and then return Next n records .The Function module and the report program are in different system .
Thanks in Advance.

Use open cursor and fetch cursor.
Check the program as in SAP Help.
DATA: BEGIN OF count_line,
 carrid TYPE spfli-carrid,
 count TYPE i,
 END OF count_line,
 spfli_tab TYPE TABLE OF spfli.
DATA: dbcur1 TYPE cursor,
 dbcur2 TYPE cursor.
OPEN CURSOR dbcur1 FOR
SELECT carrid count(*) AS count
 FROM spfli
 GROUP BY carrid
 ORDER BY carrid.
OPEN CURSOR dbcur2 FOR
SELECT *
 FROM spfli
 ORDER BY carrid.
DO.
FETCH NEXT CURSOR dbcur1 INTO count_line.
IF sy-subrc <> 0.
 EXIT.
ENDIF.
FETCH NEXT CURSOR dbcur2
 INTO TABLE spfli_tab PACKAGE SIZE count_line-count.
ENDDO.
CLOSE CURSOR: dbcur1,
 dbcur2.

DB Tools Fetch Next Recordset

I am having trouble iterating through the set of recordsets returned from a query that returns multiple tables. I am using the DB Tools Fetch Next Recordset.vi in a loop to iterate through recordsets until they have all been processed. One problem I have is that there is no indication that you have iterated past the end of recordsets. DB Tools Fetch Next Recordset does not produce an eof type indication like you get when iterating through records in a recordset.
My code is attached:
1. Open a database and execute a query that returns more than 1 table (SELECT * FROM tblA SELECT * FROM tblB)
2. Fetch the current recorset data and store in array.
3. Use DB Tools Fetch Next Recordset to move to the next recordset.
Question: What is the stop condition to test for?
Errors propogate through to the close vi which reports:
Error 97 occurred at Rec Get Recordset Properties (R).vi->Rec Fetch Recordset Data (R).vi->Untitled 1
Possible reason(s):
Unknown System Error in Rec Get Recordset Properties (R).vi->Rec Fetch Recordset Data (R).vi->Untitled 1
Any help or example for navigating recordsets?
Thanks,

Iterate recordsets3.png ‏21 KB

Hi,
I have a sql query in labview 2011 and i receive a lot of recordsets from it, i can group all records in arrays but i have the same error at the last cycle (i think is normal because it lost each recordset when i use fetch next recorset so the last cycle is consider like EOF and BOF at the same time) but i have other issues, when i tried to free the connection it appear error code 1045 about Rec Destroy and using the execution trace toolkit there are a lot of References Leak, i think maybe one per cycle.
My results are the expected but i have this problems.
I did a very simple example to reproduce my problems, it can use any sql db connection because it doesnt query colunms or data and presents the same things.
Thanks for your time

"Fetch Next from" very slow

Hi all ~ There is a cursor inside a store proc. and at the middle of the loop, became extreamly slow..
and I look into "sysprocesses"
"Fetch Next from cursor_name" SUDDENLY uses huge logical read.~~~~
I am using SQL 2008 R2 SP2 .
Anyone meet this kind of case before ?

Cursor invalidation WITHOUT DDL statements

Hi, all.
The db is 11.2.0.3 on a linux machine.
As we know, ddl statements on database objects cause cursror invalidation.
A number of cursor invalidation WITHOUT ddl statements means that shared pool is too small?
The following is a part of AWR report.
Library Hit % is near to 100%, but I can find a number of cursor invalidation from v$sql view.
What could cause cursor invalidation except ddl statements?
Instance Efficiency Percentages (Target 100%)
Buffer Nowait %: 100.00 Redo NoWait %: 99.99
Buffer Hit %: 99.39 In-memory Sort %: 100.00

That could cause reloads, but not invalidations.
A possible cause of invalidations on your system could be that the number of child cursors for a parent has become too large.
The following is a part of AWR report.
Library Hit % is near to 100%, but I can find a number of cursor invalidation from v$sql view.The library cache portion of the AWR would be the relevant bit if you think you have a problem with invalidations.
The instance efficiency is virtually useless at the best of times,http://jonathanlewis.wordpress.com/2006/12/27/analysing-statspack-2/ it's irrelevant in this case.

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;

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:
DECLARE

SUMX NUMBER(38);
SUMY NUMBER(38);
Y NUMBER(38) ;
Y1 varchar2(10);
Y2 varchar2(10);
X2 NUMBER(38);
XY NUMBER(38);
SUMXY NUMBER(38);
SUMX2 NUMBER(38);
X_BAR NUMBER(38);
Y_BAR NUMBER(38);
T_SUMY NUMBER(38);
T_SUMX NUMBER(38);
T_SUMXY NUMBER(38);
T_SUMX2 NUMBER(38);
T_XSUMX NUMBER(38);
R1 NUMBER(38);
R2 NUMBER(38);
A NUMBER(38);
z number(38);
B NUMBER(38);
final number(38);

How to fetch records from the database into a combo box?

Hi:
I´m really new with ABLBPM and I´m trying to fetch records from the database to display them into a combo box as valid values for a presentation but I´m using a dynamic method with this code:
for each row in SELECT campo1, campo2 from TABLE
do
solicitudes[] = [row.campo1, row.campo2]
end
return solicitudes
And the debugger says that SQL instructions can be used only in fuctions and procedures that are executed on the server.
Do you know another way to do it?
P.D. Sorry for my terrible english
Greetings

Hi Steve,
Thank you, your idea is perfect, but when I try to run the screenflow where the combo should be filled I get this error:

Why the err Invalid database Connection -CR 11 version in Visual studio 1.1

Hai all,
I am new to using the Crystal report with Visual studio 2003.I am facing Invalid database connection problem. My objective is tyring to upgrade CR 8 to CR11 with VS 1.1 framework(VC++ in .NET 2003).All things like ODBC connection with MS SQL server 2005,generating report going fine with CR8 version but invalid database connection error comes with CR11 version. The configuration details and Code snippet are below for your ref,
Upgrading CR8 to CR11 with VS .NET 2003.
Application framework - VS 1.1 framework
CR                            - 11 Version
DB                            - MS SQL server 2005
Connection                - ODBC
DLL                          - CRPE32 DLL (Version11)
Code snippet:
CODBCDatabase * pDatabase = pApp->GetDatabase();
BOOL bRes;
bRes = ::PELogOnSQLServerWithPrivateInfo(_T("pdsodbc.DLL"), pDatabase->m_hdbc);
Note: pdsodbc dll not found in local and anywhere.But it supports CR 8 but not CR 11.So i downloaded and put it in appropriate place exe path\system32\system and tested.Used and tested p2sodbc dll also but "Invalid DataBase connection" err came.Followed some instruction like changing the Data source name,DSN path,re installing CR 11 version and all but same problem coming.
::PELogOnSQLServerWithPrivateInfo() declation is in the following link
http://www.arcaretentores.com.br/FTP/Format/Report/ProgramF/SEAGAT~1/CRW/DEV/Help/HTML/12a_0708.htm
Thanks in advance

Thanks for your reply
   The API i have given is not available in Crystal report 11.So i tried with the PELogonServer API of version 11.It also failed.
I am unable to understand the suggestions you gave to me 1) The Report Designer Component (RDC)
2) The CR Assemblies for .NET.
Can you give any link that have related samples or articles to implement the above topics please?
Thanks again,

Af:table fetching next range of data

Hi!
I have a table component on jsf page, property RangeSize set to 25(default). Now I want to invoke a method from my managed bean each time when is fetching next range of data of ViewObject(next 25 rows). But how can I invoke this method? Does anybody have such example?
Thanks for answers.
Jdeveloper version: 11.1.2.2.0
Regards, Stanislav

Hi, John!
Ok :)
I have a transient attribute on ViewObject. Now this attribute calculates by groovy expression. (adf.object.applicationModule.method1 invokes on each row). The problem is that this method isn't trivial and it has some common calculations and some specific calculations for current view row. Now I wan to speed up this thing. I wrote a method in manage bean, that does executes logic like on adf.object.applicationModule.method1. But I divided common calculations(now they have performed once) and specific calculations for current view row(now they have performed in cycle). It calculates faster, but only for first 25 rows. When I fetch next 25 rows, this method doesn't invoke. So, I want to invoke this method after fetching next range of data :) With first variant I don't have a problem with calculation after fetching next range of data.
