Report using cursors and loop

Hi,
can anybody suggest what kind of report and in what way I have to use if I want to write query using cursors within loops?
Thanks!
Karina.

Hi,
I found the solution. I just rewrite all cursors within one SQL statement and it works.

insert new row
4. I want to achieve this using store procedure.
Please help me how to do looping,how to use cursor and all other necessary thing to achieve this.

DECLARE
   b   NUMBER;
BEGIN
   UPDATE tbl_sale
      SET a = b
    WHERE a = 1;

Why use cursor and for loop?

Hi All
So in general why would we use a cursor and a for loop to do update in a stored procedure?
Why wouldnt we just use a single update statement ?
is there compelling reason for using a cursor and a for loop: I am reading some code from a co-worker that the business logic for the select (set need to be updated) is complex but the update logic is simple (just set a flag to (0 or 1 or 2 or 3 or 4).
But eventually the select come down to a key (row_id) so I re-write it using just a single sql statement.
The size of the main table is about 2.6 to 3million rows
Any thoughts on that??
The code below I just do a google for cursor for update example in case for something to play with
-Thanks for all your input
create table f (a number, b varchar2(10));
insert into f values (5,'five');
insert into f values (6,'six');
insert into f values (7,'seven');
insert into f values (8,'eight');
insert into f values (9,'nine');
commit;
create or replace procedure wco as
cursor c_f is
    select a,b from f where length(b) = 5 for update;
    v_a f.a%type;
    v_b f.b%type;
begin
open c_f;
loop
    fetch c_f into v_a, v_b;
    exit when c_f%notfound;
    update f set a=v_a*v_a where current of c_f;
end loop;
close c_f;

Adding my sixpence...
PL/SQL is not that different from a SQL perspective than any other SQL client language like Java or C# or C/C++. PL/SQL simply integrates the 2 languages a heck of a lot better and far more transparent than the others. But make no mistake in that PL/SQL is also a "client" language from a SQL perspective. The (internal) calls PL/SQL make to the SQL engine, are the same (driver) calls made to the SQL engine when using Java and C and the others.
So why a cursor and loops in PL/SQL? For the same reason you have cursors and loops in all these other SQL client languages. There are the occasion that you need to pull data from the SQL engine into the local language to perform some very funky and complex processing that is not possible using the SQL language.
The danger is using client cursor loop processing as the norm - always pulling rows into the client language and crunching it there. This is not very performant. And pretty much impossible to scale. Developers in this case views the SQL language as a mere I/O interface for reading and writing rows. As they would use the standard file I/O read() and write() interface calls.
Nothing could be further from the truth. SQL is a very advance and sophisticated data processing language. And it will always be faster than having to pull rows to a client language and process them there. However, SQL is not Turing complete. It is not the procedural type language that most other languages we use, are. For that reason there are things that we cannot do in SQL. And that should be the only reason for using the client language, like PL/SQL or the others, to perform row crunching using a client cursor loop.

I am taking a intro course online so I am trying to teach myself this. The most basic rule for designing and writing good Oracle code that will perform and will scale is to use SQL for what it is good at and using PL/SQL for what it is good at. And between the two, SQL is by far superior when it comes to crunching data in the database.
The simple maxim is Maximize SQL. Minimize PL/SQL.
What you want to do with that PL/SQL code can be done using SQL only. And since you are learning SQL and PL/SQL, it is very important that you learn the correct way to do this.
Have a look at Oracle® Database SQL Language Reference guide.
The update syntax supports:
UPDATE <dml_expression_clause>
Where this +<dml_expression_clause>+ is a SELECT statement (aka an in-line view) - that can contain joins.
Simple example. You join tables t1 and t2 to identify the rows in t1 to update. The +<dml_expression_clause>+ will define this join. The actual update part (using the SET clause) will update the relevant rows in t1.
This is also called an updatable view - though the +<dml_expression_clause>+ does not need to use an actual view.
Have a look at AskTom for a discussion on this. Also note that you can also create a view and define an "instead-of" trigger on the view - this particular feature enhances the ability to update DML expressions - but is not a prerequisite.
Note that there can be very significant performance degradation by NOT using an UPDATE on a +<dml_expression_clause>+ and instead coding that manually via PL/SQL.
So do yourself a favour and learn the CORRECT way to resolve the type of UPDATE problem you have.

Is it possible to use cursors and zooming in the plotxy function that outputs pictures?

I use the plot multi xy function in my vi that outputs a picture. And I wonder if it is possible to use cursors and zooming with this output picture?
Thanks,
Ogulcan Kaya

Hi Ogulcan,
it is, but not as straightforward as with standard graphs.
As a starting point take a look at the example shipped with LV: Modified Smith Plot with Zooming.vi; you find it in picture examples.
Good luck,

Generate report using CURSORS? - Simple question

Folks,
I'm a real newbie still with PL/SQL so please excuse my ignorance I have a simple report I need to generate. The following SQL statement gets me all my "header" records:
SELECT OHA.ORDER_NUMBER, HEADER_ID, ATT11, ATT12, ATT16
FROM XXXWD.WD_DUPS DUPS, OE_ORDER_HEADERS_ALL OHA
WHERE OHA.ATTRIBUTE11 = DUPS.ATT11
AND OHA.ATTRIBUTE12 = DUPS.ATT12
AND OHA.ATTRIBUTE16 = DUPS.ATT16
AND (OHA.FLOW_STATUS_CODE NOT IN ('CLOSED', 'CANCELLED'))
AND (ATT11 <> 'WESTERN SERVICE')
ORDER BY ATT11, ATT12, ATT16
What I want to do now is have a second script that will display all my detail records. Something like:
SELECT OLA.LINE_NUMBER, OLA.ORDERED_ITEM, OLA.FLOW_STATUS_CODE
FROM OE.ORDER_LINES_ALL OLA
WHERE OLA.HEADER_ID = OHA.HEADER_ID
I expect I'd do this with two cursors, passing the value of my HEADER_ID to my second cursor. But when I've used cursors before, they primarily have been to import data, and manipulate data. But what if I just want to create a report using these?
I essentially want to display my header information, and then any lines below that data (if there is any, there may be a header with no lines).
Can I create a simple report like this with cursors? Any help with this would be IMMENSELY appreciated. I'm really under the gun... :)
Thanks so much!
Steve

Here's one query that will give you everything:
SELECT OHA.ORDER_NUMBER
      ,OHA.HEADER_ID
      ,DUPS.ATT11
      ,DUPS.ATT12
      ,DUPS.ATT16
      ,OLA.LINE_NUMBER
      ,OLA.ORDERED_ITEM
      ,OLA.FLOW_STATUS_CODE
FROM   XXXWD.WD_DUPS        DUPS
      ,OE_ORDER_HEADERS_ALL OHA
      ,OE.ORDER_LINES_ALL   OLA
WHERE OLA.HEADER_ID   = OHA.HEADER_ID
AND    OHA.ATTRIBUTE11 = DUPS.ATT11
AND    OHA.ATTRIBUTE12 = DUPS.ATT12
AND    OHA.ATTRIBUTE16 = DUPS.ATT16
AND    OHA.FLOW_STATUS_CODE NOT IN ('CLOSED', 'CANCELLED')
AND    DUPS.ATT11 <> 'WESTERN SERVICE'
ORDER BY OHA.ORDER_NUMBER
         ,OLA.LINE_NUMBER
         ,DUPS.ATT11
         ,DUPS.ATT12
         ,DUPS.ATT16
;(correction in order by clause)

Learning... cursor and loop... suggestions?

Although I'm looking for non version specific information... Here is what I'm running on.
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
PL/SQL Release 11.2.0.3.0 - Production
CORE    11.2.0.3.0    Production
TNS for Solaris: Version 11.2.0.3.0 - Production
NLSRTL Version 11.2.0.3.0 - Production
I'm trying to figure out the whole relationship and execution of inserting data into a table, manipulating the table and anything else via a procedure using a cursor and a loop.
Sounds simple, but all the examples I find out there all deal with dbms_output.. obviously because it's 'safe'...
So I'm trying to use context that my mind makes quick sense of.
I built a simple table with vehicle makes, with the intention of using exercises to add models, trim levels, engines...pretty much all vehicle specifications.
CREATE TABLE VEH_COMP
MAKE          VARCHAR2(20 BYTE),
MODEL         VARCHAR2(50 BYTE),
TRIM          VARCHAR2(50 BYTE),
ENGINE        VARCHAR2(50 BYTE),
TRANSMISSION VARCHAR2(50 BYTE),
HORSEPOWER    NUMBER,
TORQUE        NUMBER
TABLESPACE USERS
RESULT_CACHE (MODE DEFAULT)
PCTUSED    0
PCTFREE    10
INITRANS   1
MAXTRANS   255
STORAGE    (
            INITIAL          80K
            NEXT             1M
            MINEXTENTS       1
            MAXEXTENTS       UNLIMITED
            PCTINCREASE      0
            BUFFER_POOL      DEFAULT
            FLASH_CACHE      DEFAULT
            CELL_FLASH_CACHE DEFAULT
LOGGING
NOCOMPRESS
NOCACHE
NOPARALLEL
MONITORING;
Next I tried to build a simple sql block to insert a handful of Auto makes into the table... I know this is ugly, and here is where I'm looking for suggestions for improvement.
DECLARE
   CURSOR m1
   IS
   SELECT 'Ford' as make FROM DUAL
UNION ALL
SELECT 'Chevy' FROM DUAL
UNION ALL
SELECT 'Dodge' FROM DUAL
UNION ALL
SELECT 'BMW' FROM DUAL
UNION ALL
SELECT 'Audi' FROM DUAL
UNION ALL
SELECT 'Mercedes' FROM DUAL;
BEGIN
   FOR v_make IN m1
   LOOP
      dbms_output.put_line(v_make.make);
      insert into veh_comp (make) values (v_make.make);
   END LOOP;
END;
Now I'm looking to add models. Like Ford Mustang, Ford Lightning, Chevy Corvette, Chevy Camaro, Dodge Charger, Dodge Challenger, Dodge Viper, BMW M5, BMW M3, BMW M6...
Then I need to add engine sizes... I6, V8
Then I need to add transmission... M6, M5, A5, A6, A8
I'm a little confused as how I should execute this part. Or better yet, I'm sure there is a better way to include it all at once...
I've been looking on line on how to do this and again...only really finding dbms_output.put_line. And I did grasp how I could do something along this lines from using a spool file. But I really want to learn to be more efficient.
What's the best way to do this?
Thanks.

From what I can gather from the code, if I create some example data, you just want a query that does something like...

You already had the iteration part in your query, you just needed the Group number which is achieved using a dense_rank on the result.

Project Stock report using QBEW and QBEWH tables

Dear All,
First of all Happy New Year to all of you.
Here is my question: I want to build a ABAP report for stock situation for project stock. The report demands the stock by closing month. Suppose I run the report for month 11/2010, it should show the closing stock at the end of the month 11/2010.
Now I am using the values from table QBEW for this purpose.But QBEW table shows only current entries. If a material stock is changed or value is changed, it goes into history table QBEWH.
Now problem is that if I try to make sum of QBEW and QBEWH, the stock value is excessive. Now I am not sure which entries I should consider from QBEWH table for this purpose.
Has anybody worked on similar requirement?
Thanks in advance!
Regards,
Mahendra Dighe

Hi,
Please try the report S_P00_07000140 - Inventory and Raw material for special stock report.
Thanks.

I created a Pages document inserting 2 columns using 1) Inspector 2) Layout 3) columns. How do I decrease the height of the column. Have tried to use cursor and drag down the top border, but that does not reset the top border.

Set your columns back to one for the moment. In layout mode, insert a Text box. Place it in the upper left corner of your document, and drag down and right to the size of the container for your two columns. Click inside the Text Box, and now bump up your columns to 2. Your two columns are now contained in this resizable Text Box.

Standard SAP Reporting Using Classes and Characterstics

Hi Experts,
I am currently interested in if there are any options to using classes and characteristics within standard reporting in SAP ECC. I know some reports have the selection critiera and allow for other fields to be added to reports. Does anyone know the reports that use classes and characteristics or have the ability to use them. Any help is appreciated.
Regards,

Consultant 01,
I am not sure of the specifics of your question. The reporting approach depends on the objective of the reports and the business requirements. In general, transaction MC03 can be use to report via classification characteristics. This key figure reporting option covers many classifying attributes.
If you want to report using batch classification and characteristic values, BMBC offers options for reporting on batches. In this case you may use the classification tab of BMBC to enter the batch class for "search with batch class" and/or "search with selection class". The latter allows you to view and/or narrow your search by characteristic values.
I hope that this helps.

Wayne
