Can we create internal table from txt file seperated by space?

Hi all,
I have text file abc.txt :
BP1 SAP1
BP123 SAP2
Now I can read this file GUI_UPLOAD FM
But I want to return this as table with two columns and two rows.
First row with two columns: BP1 SAP1
Scond row with two column: BP2 SAP2
I tried using
TYPES:
BEGIN OF i_po_data,
BP(3) TYPE c, " lmax length of the line of the text file
BP_name(10) TYPE c,
END OF i_po_data.
but in this case
First 3 characters will be filled in first column.
But in the second row BP123 , BP1 will be in first column but
'23' will not fit in first column.
How to insert the data in the first column just by space?
so that BP123 can also fit in the second column.
Thanks,
SUSHANT

hi,
if you have declared a variable of length 3 ,then how can you store data in that varaible which is more then 3 in length?
change your varaible length to get required result.

Storing internal table from XML File into DDIC

Hi everybody,
im trying to store an internal table <b>without</b> knowing the content - means the structure (fields)- into th DDIC, but i failed. The code is:
DATA xslt_error TYPE REF TO cx_xslt_exception.
TRY .
perform load_file using 'D:/usr/YTGVF_asXML.xml'    changing itab_XMLResult.
      refresh itab_tableA.
      call transformation id
        source xml itab_XMLResult
        result GREATEST = itab_tableA.
CATCH cx_xslt_exception INTO xslt_error.
DATA: xslt_message type string .
xslt_message = xslt_error->get_text( ).
write xslt_message.
ENDTRY.
form load_file
using    path type localfile
changing tab type table.
data:    s type string,
           filelength type i.
s = path.
refresh tab.
call function 'GUI_UPLOAD'
    exporting filename   = s
               filetype   = 'BIN'
    importing filelength = filelength
    tables     data_tab   = tab
    exceptions others     = 1.
endform.                    "load_file
So, how can i store itab_tableA, without knowing the content (fields) of the table? The XML-File is of type asXML - i guess there should be a solution.
Thanks for all replies!
BG, Jim

Absolutely, I don't see why that would be a problem.
After parsing through the schema or DTD, you would know what the structure of the XML file coming through would be. So it would be basically uploading the file to SAP and then parsing the schema or DTD file, you will come to know the structure of your XML.
And once you know the structure, you can create your <a href="/people/subramanian.venkateswaran2/blog/2004/11/19/dynamic-internal-table internal table</a>, and put the values from the XML file in the same.
Considering my limited knowledge in XML, I am not able to provide information regarding , if there are any function modules/classes which SAP supports to directly read an XML schema/DTD and create a table of that sort. But the above inputs should help you in your way...

Function module to get data into internal table from Excel file sheets

Hi,
I have to upload customers from excel file.
we are donloading customer data excel file sheets.
Customer data in 1 sheet, tax data the other sheet of same excel file, Customer master-Credit data in other sheet of same excel file.
so i have 3-4 sheet in one excel file.
now my requirement is to get the data from excel file into internal table.
is there any function module.
Thanks & Regards

I am sending you the idea with an example how you can upload data from an EXCEL file into an internal table. I am not sure if you can take data from different sheet in the same EXCEL file. I think that this is not possible (try it )
Upload the data into an internal table, like the way that I am describing in the above:
DATA: L_MAX_COL_NB TYPE I.
DATA: l_file_name LIKE RLGRAP-FILENAME.
Just to be sure that is the correct type for the FM.
l_file_name = P_FILE_NAME.
L_MAX_COL_NB = 58. "Maximum nb of colums that the FM can read.
CALL FUNCTION 'ALSM_EXCEL_TO_INTERNAL_TABLE'
       EXPORTING
            FILENAME                = l_file_name
            I_BEGIN_COL             = 1
            I_BEGIN_ROW             = 2
            I_END_COL               = L_MAX_COL_NB
            I_END_ROW               = 9999
       TABLES
            INTERN                  = PT_EXCEL
       EXCEPTIONS
            INCONSISTENT_PARAMETERS = 1
            UPLOAD_OLE              = 2
            OTHERS                  = 3.
IF SY-SUBRC <> 0.
ENDIF.
Now you should upload the data into your own itab. The Function Module will return to you all the an itab
from all fields and columns. Define the structure of the uploading file into SE11 - Data Dictionary. Then read the fieldcatalog of this structure. In the code that I am sending to you, I am insearting an empty line into the internal table and then I am assigning this line into a corresponding field-symbol. Then I am able to change the working area - so and the line of the itab. Propably you could you the statement APPEND INITIAL LINE TO (your_table_name) ASSIGNING <your_field_symbol>, but the example was written in an old SAP version.
FIELD-SYMBOLS:
                 <F_REC> LIKE WA_UPLOAD_FILE,      "working are of the uploading file
                 <F_FIELD> TYPE ANY.
DATA: COLUMN_INT TYPE I,
        C_FIELDNAME(30) TYPE C.
PERFORM GET_FIELDCATOLG TABLES FIELDCAT
                           USING 'ZECO_CHARALAMBOUS_FILE'.
LOOP AT PT_EXCEL.
    AT NEW ROW.
      ASSIGN WA_UPLOAD_FILE TO <F_REC>.
    ENDAT.
    COLUMN_INT = PT_EXCEL-COL.
    READ TABLE FIELDCAT INTO WA_FIELDCAT INDEX COLUMN_INT.
    CONCATENATE '<F_REC>-' WA_FIELDCAT-FIELDNAME INTO C_FIELDNAME.
    ASSIGN (C_FIELDNAME) TO <F_FIELD>.
    <F_FIELD> = PT_EXCEL-VALUE.
    AT END OF ROW.
      APPEND WA_UPLOAD_FILE TO GT_UPLOAD_FILE.
      CLEAR WA_UPLOAD_FILE.
    ENDAT.
ENDLOOP.
With Regards

Creating external table - from a file with multiple field separators

Uploading Dynamically created Internal table form Flat file

I am creating dynamic internal table as follows:
*-create dynamic internal table
CALL METHOD cl_alv_table_create=>create_dynamic_table
    EXPORTING
      it_fieldcatalog = i_fldcat[]
    IMPORTING
      ep_table        = i_modify.
ASSIGN i_modify->* TO <fs_tab>.
The dymamic internal table is created with the given Ztable in the selection screen.
Now the problem is when I try to upload this table <fs_table> using function module Call function 'UPLOAD'.
The first column of flat file is getting updated in Mandt of <fs_table>.
I want to update sy-mandt in MANDT of <fs_table> and the rest of the fields with flat file data.
e.g.
Flat file data:
100 white
101 black
<fs_table> structure is getting uploaded as below
mandt zcode zdesc
100     white
101     black
if the clint is 700
it has to be uploaded as
mandt zcode zdesc
700    100     white
700    101     black
Can someone knows what should be the approach or any other function module to be used ?

Create SQL tables from dbf files

I have hundreds of dbf files that I need to import into SQL Server. I have created a foreach loop container and have a data task within the loop that will import the data. However, it will only work if the tables are already in SQL Server.
These tables may differ depending on versions so I cannot use the Wizard. I know I can do the CREATE TABLE using variables, but how can I get the schema from the dbf file in order to dynamically fill in the columns for the CREATE TABLE statement?

Thanks Arthur. Does anyone have an example? Considering the wizard can extract the column names, there has to be a way to set this up. I am new to SSIS and have not been able to figure out a way to grab at least the column names
via a script.
The wizard may extract the names. Then dump somewhere. Then create a script say in Excel off the column names, but you also need the lengths, datatypes. What is this dbf file? Is it dBase database? Can you open a file in a text editor?
We know nothing at this point still.

NEED HELP... Creating dynamic table from data file...

Hi
I'm writing an application for data visualization. The user can press the "open file" button and a FileChooser window will come up where the user can select any data file. I would like to take that data file and display it as a table with rows and columns. The user needs to be able to select the coliumns to create a graph. I have tried many ways to create a table, but nothing seems to work! Can anyone help me?! I just want to read from the data file and create a spreadsheet type table... I won't know how many rows and columns I'll need in advance, so the table needs to be dynamic!
If you have ANY tips, I'd REALLY appreciated.....

Thank you for your help. I tried to use some of the code in the examples... I'm really new at this, so I'm not sure how to set it up. I added the code, but when I open a file, nothing happens. Here's the code I have so far...

Can we create external table from an existing database table ?

Hi everyone,
As i understand, its possible to create a new table based on an existing table without copying any values from it, using the following command;
CREATE TABLE newtable AS
(SELECT * FROM oldtable WHERE 1=2);
I would like to know whether we can do a similar thing with external tables. That is to create an external table with the same columns as of an existing table.
Thanks in advance for your answers.

You need to clear conception about external table.

Need help at date format while creating External Tables from Flat file

Hi All,
I have a flat file generated from SQL Server 2005. In that generated flat file the date format is in the format as "YYYY-MM-DD HH24:MI:SS.Millisec" like example "2007-09-08 13:32:36.568".
My task is I have to load this flat file data into Oracle database table running on 9i, but its failing at the creation of external table itself because of this date format. The target table in Oracle the date column data type is "date" only not the "TIMESTAMP".
Can any body suggest how to resolve this?
Thanks,
Sankar

Or:
SQL> select cast(to_timestamp('2007-09-08 13:32:36.568',
2 'yyyy-mm-dd hh24:mi:ss.xff') as date) dt
3 from dual;

Insert Data into Table from TXT or CSV file !!!!!

Dear All,
Recently I have started working on APEX. In Oracle Forms, we used to use TEXT_IO for inserting records into tables from txt files. Now I want to do the same thing in apex 3.2. How can I insert data into tables from txt of csv files.
Waiting of your valuable suggestions.
With kind regards,
Yousuf.

Yousuf
wwv_flow_files is used by APEX to hold uploaded files.
If you incorporate a file browse item on you page, browse for the selected file, then submit the page (having the PL/SQL process described as an on suibmit process) then what I detailed should work.
If you don't need users to have access to this then just go to Home>Utilities>Data Load/Unload in APEX and there is a handy load utility there that does it all for you.
Cheers
Ben

How create temporary table from list of values

Can you anybody advise me how can I create temporary table from list of values? I have list of values and need create temporary table for next use with command JOIN etc.
Thank you for help

NO, you can not create temporary table in oracle on the fly ( Like #Tabels in SQl Server or Sybase ) , you will have to use the GTT i.e Global Temporary Tables
check the following link GTT :
to flush the tables after commit
CREATE GLOBAL TEMPORARY TABLE my_temp_table (
column1 NUMBER,
column2 NUMBER
) ON COMMIT DELETE ROWS;In contrast, the ON COMMIT PRESERVE ROWS clause indicates that rows should be preserved until the end of the session.
so to keep rows in Table after commit
CREATE GLOBAL TEMPORARY TABLE my_temp_table (
column1 NUMBER,
column2 NUMBER
) ON COMMIT PRESERVE ROWS;

Can I create a table in a procedure submitted to job queue?

I have created a package (with AUTHID CURRENT_USER) where some of the procedures create temporary tables to facilitate processing. These procedures run just fine when executed directly from within an anonymous block at the SQL*PLUS level. However, when I submit the procedures to the job queue (via DBMS_JOB.SUBMIT), the job is submitted successfully but fails when run. Investigating the Alert Log shows an error of insufficient privilege on the CREATE TABLE command in the procedure.
QUESTION:
Can I create a table from a procedure running in the Job Queue? If so, then how to get it to work? Does the job run in a different environment that needs Create Table privileges set to my schema?
Thanks for any info you can provide.
John

FYI: Found the problem. In the Administrator's Guide (of course not in the supplied packages documentation about DBMS_JOB) I found:
"How Jobs Execute
SNP background processes execute jobs. To execute a job, the process creates a session to run the job.
When an SNP process runs a job, the job is run in the same environment in which it was submitted and with the owner's default privileges.
When you force a job to run using the procedure DBMS_JOB.RUN, the job is run by your user process. When your user process runs a job, it is run with your default privileges only. Privileges granted to you through roles are unavailable."
And of course we had set up our users to get all privileges through Roles, so CREATE TABLE wasn't one of my DEFAULT PRIVILEGES!
It sure would be nice if Oracle documentation could get its act together and provide ALL information about a topic in a logical place. The effort to find the information about privileges occurred after it took me 1/2 hour to figure out why my submissions were failing - I didn't have the ';' included in the quoted string for the procedure to be called - which I only figured out after looking at the code for DBMS_JOB where it made the note to make sure you include the ';'. Wouldn't it be good to have that MINOR DETAIL mentioned in the description of DBMS_JOB.SUBMIT?????

Uploading data from excel file to a dynamically created internal table

Hi,
I have a requirement where i have to upload data from an excel file into a database table. I would be able to determine the structure of the table only at runtime based on the user input.. so i have created an internal table dynamically.
Could you please tell me if its possible to upload data from an excel file to the dynamically created internal table using any function modules?
I thought of doing this by declaring a generic internal table of one field and then uploading the *.csv file into it and then splitting it based on "," and then assigning it to the field symbol referencing the internal table.. but my file length exceeds 132 characters and i'm only able to get data of lenght 132 char's in my internal table ( generic one).
Could anyone please show me a way around this.
Thanks in advance,
Harsha

How to delete a field from a Dynamically created internal table

Hi friends,
I have got a requirement in which, I will be entering the table name and Excel file from seletion-screen.
based on the Table I have entered in the selection-screen I need to create a dynamic internal table so that I can fill that Execel data into that internal table and later i using BDC i can I can fill the database table using SM30 transaction.
here. my problem is that, When I am creating internal table dynamically, MANDT filed is also getting created in the internal table.
please, help in deleteing the filed MANDT from the internal able.
following is the code which creates the dynamic internal table.
CREATE DATA dy_table TYPE TABLE OF (p_tabname).
assign dy_table->* to <dyn_table>.
please provide, if any sample code is available.
Regards,
Xavier.P

Hi,
You can use this logic,
While creating the Dynamic filed catalog try to avoid MANDT field.
Ex:
*Dynamic creation of a structure
CREATE DATA LP_STRUCT TYPE (V_TABLE).
ASSIGN LP_STRUCT->* TO <FS>.
*Fields Structure
OF_SDESCR ?= CL_ABAP_TYPEDESCR=>DESCRIBE_BY_DATA( <FS> ).
LOOP AT OF_SDESCR->COMPONENTS ASSIGNING <COMPONENTS>.
*Field MANDT not displayed
    IF SY-TABIX = 1 AND <COMPONENTS>-NAME = 'MANDT'.
      CONTINUE. " Next loop
    ENDIF.
*Build Fieldcatalog
    LS_LVC_CAT-FIELDNAME = <COMPONENTS>-NAME.
    LS_LVC_CAT-REF_TABLE = V_TABLE.
    APPEND LS_LVC_CAT TO LT_LVC_CAT.
    CLEAR LS_LVC_CAT.
ENDLOOP.
