XSU : Updating records in the table

Hi,
XSU seems to be assuming that the data from the XML doc has to be always INSERTED into the database. Does it not have to UPDATE existing records and INSERT only the NEW RECORDS?
How should this be implemented?
null

A future release is planned to offer this so-called "upsert" functionality, but the current release requires you to know whether you want to insert, update, or delete.
You can use the insert functionality, in combination with an INSTEAD OF INSERT trigger to programmatically handle the "update-if-already-exists" functionality.
See Example 12-17 on page 465 of "Building Oracle XML Applications" for a concrete example of this hand-coded "upsert" functionality.

How to update Records of SAP table from .CSV file

Hi,
I have written a code which takes a data from (,) delimited CSV file and adds it into the Internal table.
Now I want to update the all fields in SAP table with the Internal table.
I want to use Update statement.
Update <table Name> SET <field needs to update> WHERE connditon.
I don't want to iterate through thousand on record in sap table to check the where condition.
Could you please tell me how to do it.

Hi. I thing you will not workaround the iterating of the internal table.
You can pre-load all the records into another internal table
check lt_csv[] is not initial. " important, otherwise next select would read all records of the table
select .... into lt_dbitab for all entries in lt_csv where key-fieds = lt_csv-key_fields...
check sy-subrc eq 0 and lt_dbitab[] is not initial.
then do in-memory update of the it_dbitab
loop at it_dbitab assign <fs>.
read table lt_csv assign <fs_csv> with key ... " lt_csv should be sorted table with key, or you should try to use binary search
if sy-subrc eq 0.
...change required lt_dbitab fields: <fs>-comp = <fs_csv>-comp...
endif.
endloop.
ant then you can do mass-update
update dbtab from table lt_dbitab.
From performance view, this solution should be much faster than iterating lt_csv directly and updating every single database record

How to update records in a table based on user selection..

Hi all,
This time the above doubt is totally based on the logic of coding which I tried a lot but didn't get any solution. so atlast I come to sdn site.
please help..
The requirement is like that I have a table with 6 fields (1 primary key and other are nonkeys). If the user inputs some values in the fields on the screen, then a row will be added in the table. Upto this i have done well. but when the user want to change some value in the existing row of the table my program unable to do so. Because I couldn't get any logic to do that as there are 5 nonkey fields, so if any one field is modified then the respective row should be selected first based on the user selection and then it should be updated.
At this point I could not get any idea as it may take a lots of if conditions (I guess) to reach to that particular row.
Please help..
thanks ,
sekhar

Hi Sekhar,
I am afraid, the whole design of your program is wrong, let me explain
Let us say you have two rows(5 non key fields) that the user wants to update and the data in these five non key fields are identical and in your program you are getting a number(which is the key) using a number range object. So you will have two entries in the table for the same data.
And on the update page when the user enters the non key fields, how will the program know(or for that matter any one of us) which record to pick, if you have two identical books and if asked for a book wouldn't you ask which one among these two do you want?
Possible Solution: Identify a possible key maintaining the integrity of the data, that is a combination of the non key fields which will help you identify a unique row and make these fields as key fields in the table.
A more costly solution(if you do not want to change the non key field keys to key fields) would be to, adding a check(using select statement) to see if the non key fields combination already exists in the Z table before inserting a record into the table.
If yes, throw a message to the user and just update the values in the table, else insert the record.
Another solution would be to, use the non key fields to generate a key(using some logic) and using this instead of the number range object.

Chen

Selecting records in the table control

Hi Friends,
I have the requirement to be displayed in the table control, I got the data displayed in the table control. Now I need to select some of the records from the table control and update in the database. When I am trying to do that i am able to select only one records instead of some number of records. When I try to select the second record the first record which i selected is being unselected. Can any one tell me how to select more than one record in the table control.
Regards,
Line

hello,
to select more then 1 record
1> you need to put CHECK BOX FEILD
or
1> you have to manually use control and select the feilds.

But I am not sure why it is giving an exception as Violation of PRIMARY KEY.
The update method works fine for the same client.
The exception only happens when I am trying to insert a new record.
Please help me to figure out this problem.

If you are absolutely sure that you do not have such a row already in your table, open a case with customer support and reference CR321312. I believe the work-around is to put ld-server-core.jar in your client classpath.
Correction: put ld-server-app.jar in the client classpath

Override the unique record of the table

friends
i am having a record in the table , and always i want the latest value in the table.
the record is with 4 fields.
mandt primary key
numb primary key
username
date
now in the program i read the numb from the ztable and after reading that
i want to update the field with +1 ie override the old record.
I tried with update and modify statement but they are inserting the new record,
i tried the where clause but that is not working.
when i am using modify statement i am using numb+1 , so it is inserting the new record.
How to handle this situation , please advice

Hi,
As Number is primary key, After reading and adding Number then you need to delete the existing latest record and Insert the new record.
For EX
NUM USERNAME
0001 NAREN
0002 SATISH
0003 RAVI
Then last number is 0003 , add 1 then num is 0004.Then delete 0003 RAVI
and add 0004 RAVI
then DATA becomes
NUM USERNAME
0001 NAREN
0002 SATISH
0004 RAVI
Hope this will help you.
Thanks and Regards,

Incomplete Data on report (report does not show all records from the table)

Hello,
I have problem with CR XI, I'm running the same report on the same data with simple select all records from the table (no sorting, no grouping, no filters)
Sometimes report shows me all records sometimes not. Mostly not all records on the report. When report incomplete sometimes it shows different number of records.
I'm using CR XI runtime on Windows Server 2003
Any help appreciated
Thanks!

Sorry Alexander. I missed the last line where you clearly say it is runtime.
A few more questions:
- Which CR SDK are you using? The Report Designer Component or the CR assemblies for .NET?
- What is the exact version of CR you are using (from help | about)
- What CR Service Pack are you on?
And a troubleshooting suggestion:
Since this works on some machines, it will be a good idea to compare all the runtime (both CR and non CR) being loaded on a working and non working machines.
Download the modules utility from here:

How can I update record in the block that Data Source is PROCEDURE?

I like use Procedure as the Data Source of block.It's very flexible.
Usually I do this only query the record,but now I must update record in the block that Data Source is Procedure.
What next step can I do?Can anyone offer some examples?
This is example, you goto

Using combination of insert into and select to create a new record in the table

Hello:
I'm trying to write a stored procedure that receives a record locator parameter
and then uses this parameter to locate the record and then copy this record
into the table with a few columns changed.
I'll use a sample to clarify my question a bit further
-- Create New Amendment
function create_amendment(p_mipr_number in mipr.mipr_number%TYPE, p_new_amendment_number in mipr.amendment_number%TYPE)
return integer is
new_mipr_id integer;
begin
THIS is causing me grief See comments after this block of code
insert into mipr
(select mipr_id from mipr where mipr_number=p_mipr_number),
(select fsc from mipr where mipr_number=p_mipr_number),
45,
(select price from mipr where mipr_number=p_mipr_number),
practical,
(select part_number from mipr where mipr_number=p_mipr_number);
THe above will work if I say the following
insert into mipr
(select * from mipr where mipr_number=p_mipr_number);
BUt, Of course this isn't what I want to do... I want to duplicate a record and change about 3 or 4 fields .
How do I use a combination of more than one select and hard coded values to insert a new record into the table.
/** Ignore below this is fine... I just put a snippet of a function in here ** The above insert statement is what I need help with
select (mipr_id) into new_mipr_id from mipr where mipr_number=p_mipr_number + amendment_number=(select max(amendment_number) + 1);
return new_mipr_id;
end;
THANK YOU IN ADVANCE!
KT

function create_amendment(p_mipr_number in mipr.mipr_number%TYPE)
return integer is
new_mipr_id integer;
tmp_number number;
tmp_mipr_id integer;
begin
tmp_number :=(select max(amendment_number) from mipr where mipr_number=p_mipr_number);
Question:
tmp_number :=1; works..
tmp_number doesn't work with the select statement?
Obviously I'm a novice! I can't find anything in my book regarding tmp variables... What should I look under is tmp_number a
variable or what? In my Oracle book, variable means something different.
Thanks!

No. of records in the table

Is any system table or a program that gives us the # of records by SAP metadata table name ?.. i have a list of table names & need to know the # of recs in all of them...so can try looking at the larger ones for analysis.. ?

Hi Venugopal,
if you want to know the no of records in a table follow these steps.
1)go to se11 and open the table
2)go to utilities->tablecontents->display
3)click on Number of Entries button which is application tollbar wihtout entering any values in the screen .
you will get the no of records existed in the table
if you want to know the no of records for all the tabels at a time then you have to write a program.follow the code below.
data:cnt type i.
SELECT COUNT(*) FROM mara BYPASSING BUFFER.
cnt = sy-dbcnt.
write:cnt.
you will get the no of records in the table in cnt.

SQL query to get last 10 records in the table?

Hi,
Can anyone tell me the SQL query to get last 10 records in the table?
Thanks!!
MCP

Please, define what "last" means. Sets are unordered by definition, so if you want to retrieve rows from a table in a specific order you need to specify what that order is - e.g. by maintaining a value in a column (or a combination of columns) that you can use in the ORDER BY clause of the SELECT statement.
If, for instance, you kept the time when the row was inserted in a special column (InsertedTime), you could use this in your query like this:
select top (10)
<column list>
from <table or view>
where <restriction(s)>
order by InsertedTime desc;

How to find last inserted record in the table.

Version: Oracle 10g
I have a table called "Manufacture" and 3 columns as mfno,itemname,quantity.
How to find last inserted record in the table "Manufacture".
As i come to know that Rowid is not result perfect results. Please provide your inputs.

How to find last inserted record in the table "Manufacture".Not possible as your data model does not cater for it. That simple.
If there is a need to determine some order or associate some time to an entity, then that should be part of the data model - and a relationship, or one or more attributes are needed to represent that information. Thus your data model in this case is unable to meet your requirements.
If the requirements are valid, fix the data model. In other words - your question has nothing to do with Oracle and nothing to do with rowid, rowscn or other pseudo columns in Oracle. It is a pure data modeling issue. Nothing more.

Updating ztable from the table maintenance

hi,
I want to knw how and where to check , whether the records which user has entered in the table control of new entries screen exists in the ztable table or not . if the same record exists then that record should not go for saving it shd be deleted when it is detected that it exists in the ztable . can any one tell me how . where and what code to be written . so that the duplicate entries are deleted and others entries get appended in the database.
thank you.

Hi
if you have declared some Primary key fields then by default when you enter the records in the Table maintenance using SM30 it will not allow duplicate records with the same key fields
You can check the Table entries in SE16 Tcode
go to Se16 enter table name execute and see the table records
