i want to read from 4 fields of a form, concatenate it and write them into once field and write in one column in database..how to

I am getting data from the table Pt_types. The columns are pt_a, pt_b, pt_c, pt_d.
PURPOSE of the form: the viewer will select the types and press submit.
Next action: To submit the four fields (pt_a, pt_b, pt_c, pt_d.) into the column (pt_eq) in the table problem.
This is done to keep record of the reports entered by the staff. The (problem) table provides information to generate report, for maintainance.

Read data from MDM For Lookup and Flat table using MDM ABAP API

Hi,
I have requriment to read data from MDM from FLAT and Lookup table using MDM ABAP API. My design is like this ,
I have one ITEMS (Main table in MDM) and inside that i have one Lookup flat table ITEM_TYPE , my requriment is to read Item number and its related Item type.
From ABAP.
Please help if any body has any idea.

HI Guys,
I found my solution by myself. Below is the solution , hope this will help others:-
Retrieve data from MDM using MDM ABAP API.
Step- 1. Create structure in SAP with the same name as that of MDM field code for MDM Main table.
Step-2. Create another structure in SAP having all lookup fields of MDM , fieldname in ECC must be same as that of MDM field
code.
Step-3.Create structure in SAP for individual lookup field(Single Field only)   with the same name as MDM Field code.
Step-4.

Can Oracle Portal read data from an access DB and loaded it an Oracle DB?

Hi All.
Does Oracle Portal provides a portlet to read data from an access db so that i can transfer it to my Oracle DB?.
I believe Application Express does that .... Any portlet maybe ...?
Regards, Luis ...!

There are portlets that read from a DB to make reports, you can try to create a form portlet so you can make inputs to the database, no buil-in like you wish, has to be done manually.
greetings.

Urgent help in reading data from oracle

Hi All
I was reading the data from an oracle database table through jdbc and storing them in an ArrayList, since there were around 1000 records and performing the action by iterating through the arrayList
But now the record count has gone up to 200000, so i don't want to store them in the ArrayList rather process them one after the other so that i can save the memory of the ArrayList
What are the best ways of achieving this, do i need to use some tools or anything, please let me know?
Any help would be greatly appreciated.
Thanks
Diana

Reading one record at a time from the database is very very very slow. I suggest keeping it in a large array. Memory is cheap. Read up on 'java -xmx' on how to increase the amount of memory available for java if you think you are running out of memory.
Do you really need all fields in a record and all records?
If still need to process all records, you can fetch a subset of records (say, 10000) and process them, then fetch another subset. Your sql may support fetching a subset but I dont recall the syntax.

I need to read data from a text file and display it in a datagrid.how can this be done..please help

hey ppl
i have a datagrid in my form.i need to read input(fields..sort of a database) from a text file and display its contents in the datagrid.
how can this be done.. and also after every few seconds reading event should be re executed.. and that the contents of the datagrid will keep changing as per the changes in the file...
please help as this is urgent and important.. if possible please provide me with an example code as i am completely new to flex...
thanks.....

It's not possible to read from a file without using classes from the core API*. You'll have to get clarification from your instructor as to which classes are and are not allowed.
[http://java.sun.com/docs/books/tutorial/essential/io/]
*Unless you write a bunch of JNI code to replicate what the java.io classes are doing.

Shell scripts to read data from a text file and to load it into a table

Hi All,
I have a text file consisting of rows and columns as follows,
GEF001 000093625 MKL002510 000001 000000 000000 000000 000000 000000 000001
GEF001 000093625 MKL003604 000001 000000 000000 000000 000000 000000 000001
GEF001 000093625 MKL005675 000001 000000 000000 000000 000000 000000 000001 My requirement is that, i should read the first 3 columns of this file using a shell script and then i have to insert the data into a table consisting of 3 rows in oracle .
the whole application is deployed in unix and that text file comes from mainframe. am working in the unix side of the application and i cant access the data directly from the mainframe. so am required to write a script which reads the data from text file which is placed in certain location and i have to load it to oracle database.
so I can't use SQL * loader.
Please help me something with this...
Thanks in advance.

1. Create a dictionary object in Oracle and assign it to the folder where your file resides
2. Write a little procedure which opens the file in the newly created directory object using ULT_FILE and inside the FOR LOOP and do INSERTs to table you want
3. Create a shell script and call that procedure
You can use the post in my Blog for such issues

Reading data from App Web List and Displaying in HostWeb.

Hi,
Is it possible to read list data from AppWeb and display it on a page in HostWeb?
Any approaches to achieve this?
Regards,
Rivin Jose.

Hi Rivin,
There seems no need to query an app web from host web cause App for SharePoint is designed to work as an “advanced web part” solution, it should work as a separate
component of a SharePoint site which shouldn’t be taken care on the host web side.
If you simply want to display data from app web in the host web, add an App Part into a page in the host web would be the best option for you as what Dan suggests.

How to relate data of tables returned by FM for reading data from ST03N

Hello,
I am using the FM SWNC_COLLECTOR_GET_AGGREGATES to retrieve data displayed in T-Code ST03N into my report.
I am able to get the required data in different tables like Times, Memory, Usertcode, Userworkload, Hitlist_database.
However I am unable to undertand how to relate the data of these different tables, prepare another internal table with only the fields that are required for my report and then display those details.
Like, I want to loop through one of these internal tables, read data from other internal tables and consolidate my required data. But I am unable to understand based on what criteria I can read other internal tables inside a loop of any one of the above said internal tables.
I searched a lot and found many threads and blogs related to ST03N and learnt a lot about this T-code. But I could not find how to relate the data of all these tables.
Request you to please help.
Thanks and Best Regards,
Eswar

Hi,
I see the common fields like TaskType, EntryId. But, I want to make sure that these are the fields that are enough to read the records or is there any other way that I can be sure that I am getting the correct record in my read statement. So my question is specific to the tables returned from the FM SWNC_COLLECTOR_GET_AGGREGATES and not a generic one.
Thank you for your help.
Best Regards,
Eswar.

Read data from E$ table and insert into staging table

Hi all,
I am a new to ODI. I want your help in understanding how to read data from an "E$" table and insert into a staging table.
Scenario:
Two columns in a flat file, employee id and employee name, needs to be loaded into a datastore EMP+. A check constraint is added to allow data with employee names in upper case only to be loaded into the datastore. Check control is set to flow and static. Right click on the datastore, select control and then check. The rows that have violated the check constraint are kept in E$_EMP+ table.
Problem:
Issue is that I want to read the data from the E$_EMP+ table and transform the employee name into uppercase and move the corrected data from E$_EMP+ into EMP+. Please advise me on how to automatically handle "soft" exceptions in ODI.
Thank you

Hi Himanshu,
I have tried the approach you suggested already. That works. However, the scenario I described was very basic. Based on the error logged into the E$_EMP table, I will have to design the interface to apply more business logic before the data is actually merged into the target table.
Before the business logic is applied, I need to read each row from the E$EMP table first and I do not know how to read from E$EMP table.
