How to extract data from text file to database table

Hi ,
I am trying to upload data in text file to database table using GUI_UPLOAD function .what would be the program for that.
thanks in advance.

Hi,
I don't think you have a standard sap program to upload data from file to database table...
Instead you can create a custom program like this..
DATA: T_FILEDATA(1000) OCCURS 0 WITH HEADER LINE.
DATA: T_ZTABLE LIKE ZTABLE OCCURS 0 WITH HEADER LINE.
CALL FUNCTION 'GUI_UPLOAD'
EXPORTING
    filename                      = 'C:\TEST.TXT'

How to write data to existing file using spool command?

Hi,
I am calling a stored procedure from a shell script. This stored procedure is having a CLOB object as an OUT parameter. How to write the data in CLOB object a existing file which is there in my client system. Below is the shell and sql scripts.

How to read specific lines from a text file using external table or any other method?

Hi,
I have a text file with delimited data, I have to pick only odd number rows and load into a table...
Ex:
row1: 1,2,2,3,3,34,4,4,4,5,5,5,,,5 ( have to load only this row)
row2:   8,9,878,78,657,575,7,5,,,7,7
Hope this is enough..
I am using Oracle 11.2.0 version...
Thanks

There are various ways to do this. I would be inclined to use SQL*Loader. That way you can load it from the client or the server and you can use a SQL*Loader sequence to preserve the row order in the text file. I would load the whole row as a varray into a staging table, then use the TABLE and MOD functions to load the individual numbers from only the odd rows. Please see the demonstration below.
SCOTT@orcl12c> HOST TYPE text_file.csv
1,2,2,3,3,34,4,4,4,5,5,5,,,5
8,9,878,78,657,575,7,5,,,7,7
101,201
102,202

Spool SQl data into text file using dynamic sql

Hi,
I am spooling output data into text file using command
select 'select t.mxname,bo.lxtype,t.mxrev'||chr(10)||'from mx_1234567'||chr(10)||
'where <condition>';
here mxname varchar(128),lxtype(128),mxrev(128) all are of varchar type.I want the output in format
e.g Part|1211121313|A
but due to column width the output,I am getting is with spaces.
"Part then blank spaces |1211121313 then blank spaces |A"
how can I remove these spaces between columns.I used set space 0 but not working.
Thanks in advance.
Your help will be appreciated.

Hi Frank,
I have seen your reply for SET LINE SIZE function. But, I could not be able to understand it.
I am facing similar kind of issue in my present project.
I am trying spool more than 50 columns from a table into flat file. Because of more column lengths in few columns, i am getting space. There are so many columns with the same issue. I want to remove that space.so that, data can fit perfectly in one line in .txt file without any wrap text.
Below is my sample query.sql. Please let me know the syntax. My mail id : [email protected]

How to create and read text file using LabVIEW 7.1 PDA module?

How to create and read text file using LabVIEW 7.1 PDA module? I can not create a text file and read it.
I attach my code here.

File_IO.vi ‏82 KB

Well my acquisition code runs perfect. The problem is reading it. I can't seem to read my data no matter what I do. My data gets saved as a string using the array to string vi but I've read that the string to array vi (which I need to convert back to array to read my data) does not work on the pda. I'm using version 8.0. So I was trying to modify the program posted in this discussion so that it would save data from my DAQ. I did that but I still can't read the data after its saved. I really don't know what else to do. All I need to do is read the data on the pda itself. I can't understand why I'm having such a hard time doing that. I found a possible solution on another discussion that talks about parsing the strings because of the bug in the "string to array" vi. However, that lead me to another problem because for some reason, the array indicators or graphs don't function on the pda. When i build the program to the pda or emulator, the array indicators are faded out on the front panel as if the function is not valid. Does this kind of help give a better picture of what I'm trying to do. Simply read data back. Thanks.

How to read any file using external tables.

Hi folks,
I have written an application that reads a series of csv files using external tables which works fine as long as I specify each file name in the directory i.e.......
CREATE TABLE gb_test
(file_name varchar2(10),
rec_date date
rec_name VARCHAR2(20),
rec_age number,
ORGANIZATION EXTERNAL
TYPE ORACLE_LOADER
DEFAULT DIRECTORY GB_TEST
ACCESS PARAMETERS
RECORDS DELIMITED BY NEWLINE
FIELDS TERMINATED BY ','
LOCATION ('data1.csv','data2.csv','data3.csv','data4.csv')
PARALLEL 5
REJECT LIMIT 20000;
However I have discovered that I may not know the name of the files to be processed prior to the program being run so just want to read any file regardless of it's name (although it will always be a .csv file).
Is there a way to ensure that you don't need to specify the files to be read in the LOCATION part of the syntax.
Thanks in advance.
Graham.

Right, I have now completed this, however it's currently only working as SYS as opposed to any user, however here is a detail of the scenario and the steps required in case any of you guys need in the future ......
The problem was I needed to search for csv files on my hard-drive. These files would be stored in a series of directories (a through to z), so I needed a way to read all 26 directories and process all files in these directories.
The problem was, prior to running the program, the user would remove all the files in the directories and insert new ones, but it was never known how many he would decide to do each time.
Solution: I created a table called stock_data_directories as follows ...
create table stock_data_directories(sdd_rec_no number,
sdd_table_name varchar2(50),
sdd_directory_name varchar2(50),
sdd_directory_path varchar2(100));
Then inserted 26 records like ...
insert into stock_data_directories(sdd_rec_no,sdd_table_name,sdd_directory_name,sdd_directory_path)
values(1,'rawdata_a','KPOLLOCKA','C:\KPOLLOCK\A')
insert into stock_data_directories(sdd_rec_no,sdd_table_name,sdd_directory_name,sdd_directory_path)
values(2,'rawdata_b','KPOLLOCKB','C:\KPOLLOCK\B');
etc...etc...
Then created 26 DIRECTORIES E.G.
CREATE OR REPLACE DIRECTORY KPOLLOCKA AS 'C:\KPOLLOCK\A';
CREATE OR REPLACE DIRECTORY KPOLLOCKB AS 'C:\KPOLLOCK\B';
Then created 26 external tables like the following ...
CREATE TABLE rawdata_a
(stock varchar2(1000),
stock_date varchar2(10),
stock_open VARCHAR2(20),
stock_high varchar2(20),
stock_low varchar2(20),
stock_close VARCHAR2(30),
stock_qty varchar2(20) )
ORGANIZATION EXTERNAL
TYPE ORACLE_LOADER
DEFAULT DIRECTORY KPOLLOCKA
ACCESS PARAMETERS
RECORDS DELIMITED BY NEWLINE
FIELDS TERMINATED BY ','
LOCATION ('AA.csv')
PARALLEL 5
REJECT LIMIT 20000
This basically says in directory rawdata_a it currently has 1 file called AA.csv.
Then wrote a procedure as follows ...
procedure p_process_files(pv_return_message OUT varchar2)is
cursor c_get_stock_data_directories is
select distinct sdd_directory_path,
sdd_table_name
from stock_data_directories
order by sdd_table_name;
vv_return_message varchar2(1000);
begin
-- here get the files for each directory
for r_get_stock_directories in c_get_stock_data_directories loop
p_build_external_table(r_get_stock_directories.sdd_directory_path,
     r_get_stock_directories.sdd_table_name,
     vv_return_message);
end loop;
end;
then wrote a procedure called p_build_external_table as follows ...
procedure p_build_external_table(pv_directory_path IN stock_data_directories.sdd_directory_path%type, -- e.g. 'C:\kpollock\A\
pv_table_name IN stock_data_directories.sdd_table_name%type, -- e.g. rawdata_a
pv_return_message OUT varchar2) is
vv_pattern VARCHAR2(1024);
ns VARCHAR2(1024);
vv_file_name varchar2(4000);
vv_start_string varchar2(1) := '''';
vv_end_string varchar2(3) := ''',';
vn_counter number := 0;
vv_err varchar2(2000);
BEGIN
vv_pattern := pv_directory_path||'*';
SYS.DBMS_BACKUP_RESTORE.searchFiles(vv_pattern, ns);
FOR each_file IN (SELECT FNAME_KRBMSFT AS name FROM X$KRBMSFT) LOOP
if each_file.name like '%.CSV' then
vv_file_name := vv_file_name||vv_start_string||substr(each_file.name,instr(each_file.name,'\',1,3)+1)||vv_end_string;
     vn_counter := vn_counter + 1;
end if;
END LOOP;
vv_file_name := substr(vv_file_name,1,length(vv_file_name)-1); -- remove final , from string
execute immediate 'alter table '||pv_table_name||' location('||vv_file_name||')';
pv_return_message := 'Successfully changed '||pv_table_name||' at '||pv_directory_path||' to now have '||to_char(vn_counter)||' directories';
exception
when others then
vv_err := sqlerrm;
pv_return_message := ' Error found updating directories. Error = '||vv_err;
END;
This reads every file in the directory and appends it to a list, so if it finds A.csv and ABC.csv, then using the dynamic sql, it alters the location to now read 'a.csv','abc.csv',
It ignores all other file extentions.

===========================
In the error it is showing that file expense_categories.csv in SOURCE_LOCATION not found but I am 100% sure that file is very much there.
Is anybody face the same issue?
Do we need to configure something before loading data from a flat file from OWB Client?
Any help would higly appreciable.
Regards,
Manmohan Sharma

Hi Detlef / Gowtham,
Now I am able to fetch data from flat files from OWB Server as well as OWB Client.
One way I have achieved as suggested by you
1) Creating location on the OWB Client
2) Samples the files at client
3) Created & Configured external table
4) Copy all flat files on OWB Server
5) Updated the location which I created at the client.
Other way
1) Creating location on the OWB Client
2) Samples the files at client
3) Created & Configured external table
4) Copied flat files on the sever in same drive & directory . like if my all flat files are on C:\data at OWB Client then I copied flat file C:\data on the OWB Server. But this is feasible for Non-Windows.
Hence my problem solved.
Thanks a lot.
Regards,
Manmohan

Can we cleanse and transform data at flat file or external table level?

Hi,
I have some data that I want to cleanse and transform. I don't want to cleanse it after i populate the external table, I want to get done with it at flat file level or while populating the external table. Can we cleanse and transform data at flat file or external table level through Oracle or OWB 11.2? Is it possible to run a conditional load (i.e. having a where clause or if-else-then) for an external table? Can we call oracle functions for an external table at the time of creation?
Thanks in advance.
Regards,
Ann.

Hi Oleg,
Thanks a lot for the clarification. :)
So is there a way that I can clease the data within the text file through Oracle or OWB? I have datatype mismatches in the data and most of my data is getting rejected because of that. The way I can think of, for solving this problem, is to create the external table with all fields with datatype varchar and then cleansing the data. But it doesn't seem very effecient plus it will get very complicated because I have almost 80-90 fields.
Any help?
Thanks and regards,
Ann.

How to delete data from a file using IO package

Hi All,
i am trying to remove some content of the file.
this content is not at starting of file not even at end of file.
can anybody tell me how can i delete number of lines from file using IO package.

iam having some data in text file .ex:in flowrist.txt
12/5/07,500,300,6000 like many set of datas are
there.In these if i want to delete the data based on
the date which i specified.How to do this specific
deletion?You need to open a stream to read in the file and then use the indexOf method provided in the Sting class to check if the line contains the date or whatever String you are looking for, if so then skip that line and store or re-write the lines you wish to keep, as well as some extra lines you may wish to add.
Take a look below at this example found on Google.
http://www.java-tips.org/java-se-tips/java.io/how-to-read-file-in-java.html
The above read a file line by line and prints it to console. You should be able to modify this, instead of using System.out to print the line you should use index of to check the lines for a date/String. Index of return -1 if the String you specify is not in the line you parse.

Problem while downloading data to text file using GUI_DOWNLOAD FM

Hi,
When we download the data using the GUI_DOWNLOAD FM into the text file tab delimeted(table is built dynamically),
Its coming in this format as shown below
Field1 Fileld2 Field3
1 2 3
However I want it in this way
Field1 Fileld2 Field3
1 2 3
Could someone please let me know how to achieve this?

Do something like this:
concatenate field1 field2 field3 into lv_outx "(data of sufficient length, type c)
separated by gc_tab. "Horizontal tab constant created as note above
condense lv_outx no-gaps. "squeeze out extraneous spaces but beware if you have text with spaces...drop the no-gaps.
append lv_outx to my_internal_table. "table with a single field type char, sufficient length
open dataset datasetname...
loop at my_internal_table into ls_internaltabstructure.
transfer internaltabstructure-outx to datasetName [length if needed].
endloop.

Hi,
I think you are collecting data at the same time and as aeastet told building an array will help. the example attached will give you an idea.. Though i am not sure whether this will solve your problem or not.

How to write single line text file

Hi, I need to write a single line text file using oracle forms 10g that's usually quite long 8million+ characters, I looked into utl_file but came accross the single line limit, is there any way to do this either to the client pc or to the server
Thanks

I tried using put_line but i get a ORA-29285: file write error´I´m guessing this is because of the amount of data to be written on a single line
