Uploading Data from a Flat file into Oracle Database

Hi,
I am a novice to Java . SO, please bear with me. I have a reqiurement where I have a flat file or excel file from which I need to read the data and insert into Oracle Database. The falt file will exist on the client machine. I have been reading and I see this can be done through I/O Streams. Correct me if I am wrong. I am looking for a sample code to get started. Any Java expert has an answer for it, I will appreciate it.
Thanks

How do I import the data from Excel (.xls) file into Oracle Database table

I have an excel file with 5 columns of 5000 rows.
I have to import 5000 rows of data into my oracle table with
same column names & Data types.
What is the best advise for this ?
Thanks.

You can connect to Oracle from Excel directly. I know you can read data but am not sure if you can export data.
Other option is to import the data into Access.
Create an ODBC connection for Oracle
Use the to connect to Oracle from Access

Uploading the data from a flat file into ztable

Hi,
I have a requirement where I have to upload the data from 2 flat files into 2 z tables(ZRB_HDR,ZRB_ITM).From the 1st flat file only data for few fields have to be uploaded into ztable(ZRB_HRD) .Fromthe 2nd flat file data for all the fields have to me uploaded into ztable(ZRB_ITM). How can I do this?
Regards,
Hema

hi,
declare two internal table with structur of your tables.
your flat files should be .txt files.
now make use of GUI_UPLOAD function module to upload your flatfile into internal tables.
CALL FUNCTION 'GUI_UPLOAD'
    EXPORTING
      filename            = 'c:\file1.txt'
      has_field_separator = 'X'
    TABLES
      data_tab            = itab1
    EXCEPTIONS
      OTHERS              = 1.
use this function twice for two tables.
then loop them individually and make use of insert command.

Uploading Data from a Flat File

Hi
I am trying to Upload data from a Flat File to the MDS. I have a few questions on the Process.
a) XI would be the Interface, and one end would be a file adapter with the Flat File format. On the other end, which Interface should I use - ABA Business Partner In or MDM Business Partner In. I do not understand the differences between them and where should which one be used?
B) At the moment,I want to map the data to standard Object type, Business Partner BUS1006. This also has a staging area already defined in the System. Can I view the data which is imported into the Staging area ? How so ?
C) The struture (or data) that I wish to upload has few fields, and does not map to the BP structure easily. In such a scenario does it make sense to
Create a new Object type
(ii) Create a new Business Partner type with the appropriate fields only ..
What I need to know is if either of these options is feasible and what are the pros & cons of doing this, in terms of effort, skillset & interaction with SAP Development ?
Kindly do reply if you have any answers to these questions.
Regards,
Gaurav

Hi Markus,
Thanks for your inputs.
I have tried uploading some dats from a Flat file to the Business Partner Onject type, BUS1006. I initially got some ABAP Parsing errors on the MDM side, but after correcting that, I find my message triggers a short dump - with the Method SET_OBJECTKEYS, not finding any keys in the BP structure that has been created.
Q1 - How do I get around this problem ? Is it necessary for me to specify Keys in the PartyID node of the Interface ABABusinessPartnerIn. or is it something else ?
Q2 - How is this general process supposed to work? I would assume that for staging, I would get incomplete Master data or data from flat files, which need not neccesarily contain keys. The aim is to use the matching strategies in the CI to identify duplicates and consolidate them.
Thanks in advance for your reply.

Read data from Excel and write into oracle database

Hi
I want to know how can i read data from excel and write into oracle database using java.Kindly help me out to find a solution.
Thanks and Regards
Neeta

Hai,
I am suggesting the solution.
I will try out and let u know soon.
Make a coma separated file from your excel file.
Assuming that your requirement allows to make a csv file.
This file may be passed as an file object to be read by java.Using JDBC you must be able to populate the data base.You can also use String Tokenizer if needed.
You do not want to go via sql Loader?
For reading the excel file itself do you want java?

Error while uploading data from a flat file

Hi All,
I am trying to load data from a flat file to an ODS. The flat file contains a field, say FLAT01, of numerical type(Type Decimal, Length 18, Decimals 2). I have created an infoobject, say ZIO10, with type CURR and currency field, 0CURRENCY. In the transfer rules, I have assigned a constant for 0CURRENCY as the flat file doesn't have any currecy field.
The problem is the flat file doesn't have any value in that field, FLAT01, for some records, infact most of the records. When I try to load it to BW,from applicatin server, it is throwing an error "Contents from field ZIO10 cannot be converted in type CURR ->longtext".
I have debugged the transfer rules and find that the empty value is being represented as '#' and when it is trying to copy it into the CURR type field, it is throwing the error.
Can someone please let me know how to solve it? why is it taking '#' for enpty value? Can't we change that?
Any help would be highly appreciated.
Best Regards,
James.

Hi SS,
I am sorry that I was not clear with my explanation. I have created ZIO10 as a keyfigure with type AMOUNT and the currency as 0CURRENCY.
There is no currency coming in from the flat file so I used a constant in transfer rules to fill 0CURRENCY.
The field which is coming as '#' is FLAT01 which is assigned to ZIO10.
Best Regards,
James.

Uploading data from a xlsx file into an Oracle table

Hi All,
I want to know what would be the best approach and tool to upload the data from an xlsx (excel) sheet into an Oracle table.
Can I use 'sqlldr'?
~Parag

Parag Kalra wrote:
What if the excel sheet is exported from some other third party database and not explicitly generated on Windows? I know if we can export it to excel why can't we also export it to csv but what if that option is also not available.
Also what things do I need to take into account when I export a xlsx file to csv file. I mean I hope in no circumstances there would be a data loss.How about instead of of these "what ifs" and "I hopes" you tell us exactly what you have to work with and describe the real business problem. If you ask the wrong questions, you get the wrong answers.
You "hope" that there would be no data loss? Do you really think Excel would survive as a product, much less be the overwhelming dominant product of its type, if it screwed up something that fundamental? The only thing that will be lost is the formatting meta-data.

Loading data from two flat files into one table

Hi All,
I want to load few fields from one file and few fields from another file and load the data into one table in the database.
For Ex: I have two flat files file1.csv and file2.csv and file1.csv containes 25 columns and file2.csv containes 12 columns, i want to load 20 columns from file1.csv and 7 columns from file2.csv into the table
how to combine the columns from both the files and load them into one table at a time?
Any help is appriciated
Thanks
R.G

Use external tables.
If using Oracle9 or higher connect both your csv with database as separate external tables and load the requited fields in new/requited table.

We don't know the "query on Importing data from Microsoft Excel to Oracle Database (Multiple Data Tables). "
We don't know where you posted said query.
We don't know what "some answer and reference" you received "from the forum."
We don't know what it was that your "Oracle consultant and representative from Oracle Malaysia" said was "impossible".
So on what basis are we supposed to "help or direct" to "to an expert that can help "?

What is the best way to load and convert data from a flat file?

Hi,
I want to load data from a flat file, convert dates, numbers and some fields with custom logic (e.g. 0,1 into N,Y) to the correct format.
The rows where all to_number, to_date and custom conversions succeed should go into table STG_OK. If some conversion fails (due to an illegal format in the flat file), those rows (where the conversion raises some exception) should go into table STG_ERR.
What is the best and easiest way to archive this?
Thanks,
Carsten.

Hi,
thanks for your answers so far!
I gave them a thought and came up with two different alternatives:
Alternative 1
I load the data from the flat file into a staging table using sqlldr. I convert the data to the target format using sqlldr expressions.
The columns of the staging table have the target format (date, number).
The rows that cannot be loaded go into a bad file. I manually load the data from the bad file (without any conversion) into the error table.
Alternative 2
The columns of the staging table are all of type varchar2 regardless of the target format.
I define data rules for all columns that require a later conversion.
I load the data from the flat file into the staging table using external table or sqlldr without any data conversion.
The rows that cannot be loaded go automatically into the error table.
When I read the data from the staging table, I can safely convert it since it is already checked by the rules.
What I dislike in alternative 1 is that I manually have to create a second file and a second mapping (ok, I can automate this using OMB*Plus).
Further, I would prefer using expressions in the mapping for converting the data.
What I dislike in alternative 2 is that I have to create a data rule and a conversion expression and then keep the data rule and the conversion expression in sync (in case of changes of the file format).
I also would prefer to have the data in the staging table in the target format. Well, I might load it into a second staging table with columns having the target format. But that's another mapping and a lot of i/o.
As far as I know I need the data quality option for using data rules, is that true?
Is there another alternative without any of these drawbacks?
Otherwise I think I will go for alternative 1.
Thanks,
Carsten.

Load XML data from UNIX Server Directly into Relational Database Tables

Is there a way I can load data from an XML File into Oracle Tables , without having the Input XML file in some Oracle Server Directory. My XML File resides on UNIX Application server. And I need to directly load the data into Database tables. Without loading them into the Database Directory.
Also I am looking for a solution that would not load my Database much and effect other running processes. Can it be done using SQL Loader ?
Oracle Database Version is : Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production

Thanks for your reply ,
Please would you quote an Example about : 'Load the file into that table using SQL*Loader' (From UNIX Server) Or instance of some existing thread that relates to my situation.
The Size of the File would be about 3 GB. For a similar requirement one of my peers Code which used XMLTABLE and XPATH Approach consumed a lot of resources while running and caused the other Database Applications to slow down. Thus those guys have come up with an approach to :
        Parse XML using a C Code using some STRING Functions => For a CSV or Fixed width .dat file and then use SQL Loader to just load the file into Tables.
        This approach is efficient in terms of Resources and Time(Takes 5 mins). But I am not confident about parsing XML based on String based C Functions.
         Please comment about this approach . Also if possible Suggest the best efficient way of doing this.

Problem in the BDC program to upload the data from a flat file.

Hi,
I am required to write a BDC program to upload the data from a flat file. The conditions are as mentioned below:-
1) Selection Screen will be prompted to user and user needs to provide:- File Path on presentation server (with F4 help for this obligatory parameter) and File Separator e.g. @,#,$,%,... etc(fields in the file will be separated by using this special character) or fields may be separated by tab(tab delimited).
2) Finally after the data is uploaded, following messages need to be displayed:-
a) Total Number of records successfully uploaded.
b) Session Name
c) Number of Sessions created.
Problem is when each record is fetched from flat file, the record needs to be split into individual fields separated by delimiter or in case tab separated, then proceeding in usual manner.
It would be great if you provide me either the logic, pseudocode, or sample code for this BDC program.
Thanks,

Here is an example program, if you require the delimitor to be a TAB, then enter TAB on the selection screen, if you require the delimitor to be a comma, slash, pipe, whatever, then simply enter that value. This example is simply the uploading of the file, not the BDC, I assume that you know what to do once you have the data into the internal table.
