Load text or txt file into a table when a button is clicked by the user

Can anyone please help me,
I have a form where a user comes and uploads a text file(Unicode UTF-8) and clicks a button(Upload) ,
when the button is clicked - it should load the text file data into the database table for the corresponding columns.
Note: in text file columns are sapreted by tab(\t)
& First row of text file contains column names.
& Table name should be that text file name
Can anyone please suggest me a possible solution or an approach.
Thanks,
Rathore

Load CSV file into a table when a button is clicked by the user

Hello,

thanks fro replying.
I have tried your changes but its not working. One more question is that I am having one column which contains commas, when I tried to load the file its failing. I think its the problem with commas. So I have changed the code to use the replace function for that column, then also its not working. Can anyone please suggest a possible approach. Below is my source code for your reference.
DECLARE
v_blob_data BLOB;
v_blob_len NUMBER;
v_position NUMBER;

v_blob_len := dbms_lob.getlength(v_blob_data);

Below is the function which I am using to convert hex to decimal
create or replace function hex_to_decimal( p_hex_str in varchar2 ) return number
is
v_dec number;
v_hex varchar2(16) := '0123456789ABCDEF';
begin
v_dec := 0;
for indx in 1 .. length(p_hex_str)
loop
v_dec := v_dec * 16 + instr(v_hex,upper(substr(p_hex_str,indx,1)))-1;
end loop;
return v_dec;
end hex_to_decimal;

Save data into Z TABLE when save button is clicked on BPS web application

Hi gurus,
Recently i've been working with SEM-BPS and now i have an issue,
I had to modify the BPS layout to show an input field where the user could write a comment, that was done modifying the layout in the transaction SE80 manipulating the BSP application, but now i have to save the content of those fields in a Z table when the SUBMIT event is triggered which save the content of all other standard fields. Before the saved is done i must send a pop up to confirm the action.
The trouble is where and how i must modify the code to achieve that.
Or if there's another way to solve my problem please let me know.
Best regards.
Tony Montes.

Hi Andrey,
Thanks for your time and response.
Let me told you, i was traying to implement what you say in your last post but now i'm facing a new problem,
The way i used to create the new field from HTML for the comment is not correct because the data in the GRIDLAYOUT are paged, so, when i change the page all data that i introduced in the field are ereased and i must save that values before change the page in a kind of buffer or something like that.
so my new question is this, Do you know a right way to add that field to GRIDLAYOUT? and then save this values in a Z table before save al plan data into the infocube.
Sorry for all this questions but ive read a lot of articles and I can't find anything really helpful
I've read some articles what talk about this issue but in IP, sincerely i'm NEW in this topic.
Regards.
Tony Montes.

Loading data from .csv file into existing table

Hi,
I have taken a look at several threads which talk about loading data from .csv file into existing /new table. Also checked out Vikas's application regarding the same. I am trying to explain my requirement with an example.
I have a .csv file and I want the data to be loaded into an existing table. The timesheet table columns are -
timesheet_entry_id,time_worked,timesheet_date,project_key .
The csv columns are :
project,utilization,project_key,timesheet_category,employee,timesheet_date , hours_worked etc.
What I needed to know is that before the csv data is loaded into the timesheet table is there any way of validating the project key ( which is the primary key of the projects table) with the projects table . I need to perform similar validations with other columns like customer_id from customers table. Basically the loading should be done after validating if the data exists in the parent table. Has anyone done this kind of loading through the APEX utility-data load.Or is there another method of accomplishing the same.
Does Vikas's application do what the utility does ( i am assuming that the code being from 2005 the utility was not incorporated in APEX at that time). Any helpful advise is greatly appreciated.
Thanks,
Anjali

Hi Anjali,
Take a look at these threads which might outline different ways to do it -
File Browse, File Upload
Loading CSV file using external table

you can create hidden items in the page to validate previous records before insert data.

Upload .txt file into Database Table

Hi,
I was wondering if someone could please point me in the right direction. I've been looking around the forum but can't find anything to help me achieve the following.
I would like to be able to upload a .txt file using a webpage. Then store the information inside this file into database tables.
eg. contents of mytextfile.txt:
richard
10 anywhere street, anytown, somewhere
111 222 333 444
joe
9 somestreet, elsewhere
999 888 777 666
peter
214 nearby lane, overhere
555 555 555 555
I would like to insert this data into a table.
eg. table name = CONTACTS
userid = primary key (using sequence)
username = (line 1 - richard, joe, peter)
address = (line 2)
phone_no = (line 3)
As you can see the records will appear 1 at a time and will have a blank line between records. Is there anyway for me to upload a file like this and have it placed into tables?
I have seen http://otn.oracle.com/products/database/htmldb/howtos/howto_file_upload.html but this seems to be for uploading a whole file and downloading the same file, rather than extracting data from the file.
I hope I have managed to explain my problem.
Many thanks,
Richard.

Richard,
HTML DB allows you to upload CSV files via the Data Workshop. That data would then be parsed and inserted into a specific table. Alternatively, if you have your data in an Excel spreadsheet, and it is less than 32k, you can copy & paste the data directly into HTML DB's Data Workshop, which will then parse and import it into the Oracle database.
The one obstacle you may have to overcome is converting your data from the format you outlined to CSV format. Specifically, you would have to make this:
richard
10 anywhere street, anytown, somewhere
111 222 333 444
Look something like this:
"richard","10 anywhere street, anytown, somewhere","111 222 333 444"
Hope this helps,

Hi,
Here are modifications to your vi to do what you are describing. It helps, when trying to work through issues like these on this forum to not start a new thread with each iteration of your question. Those of us that are trying to help can follow it better if you just "Reply" to your previous thread with the new, related question. If the question is for a totally new issue then a new thread is best, but when you are working through the details of essentially the same problem it really helps us follow it if you stay in one thread, and that usually means faster answers.
We also like it if, when an answer helps, you give us a rating (the more stars the better) as it is about all we get out of it!

How can I load a .TXT file into a dynamic text box?

I am sure that many people know how to load a .txt file into
a dynamic text box. But I do not. I want to be able to reference a
txt file from the server into the text box. So that when I change
the text file it changes in the flash movie without even editing
the flash file itself. Thank you.

How to import data from a text file into a table

Hello,
I need help with importing data from a .csv file with comma delimiter into a table.
I've been struggling to figure out how to use the "Import from Files" wizard in Oracle 10g web-base Enterprise Manager.
I have not been able to find a simple instruction on how to use the Wizard.
I have looked at the Oracle Database Utilities - Overview of Oracle Data Pump and the Help on the "Import: Files" page.
Neither one gave me enough instruction to be able to do the import successfully.
Using the "Import from file" wizard, I created a Directory Object using the Create Directory Object button. I Copied the file from which i needed to import the data into the Operating System Directory i had defined in the Create Directory Object page. I chose "Entire files" for the Import type.
Step 1 of 4 is the "Import:Re-Mapping" page, I have no idea what i need to do on this page. All i know i am not tying to import data that was in one schema into a different schema and I am not importing data that was in one tablespace into a different tablespace and i am not R-Mapping datafiles either. I am importing data from a csv file.
For step 2 of 4, "Import:Options" page, I selected the same directory object i had created.
For step 3 of 4, I entered a job name and a description and selected Start Immediately option.
What i noticed going through the wizard, the wizard never asked into which table do i want to import the data.
I submitted the job and I got ORA-31619 invalid dump file error.
I was sure that the wizard was going to fail when it never asked me into which table do i want to import the data.
I tried to use the "imp" utility in command-line window.
After I entered (imp), i was prompted for the username and the password and then the buffer size as soon as i entered the min buffer size I got the following error and the import was terminated:
C:\>imp
Import: Release 10.1.0.2.0 - Production on Fri Jul 9 12:56:11 2004

Import file: EXPDAT.DMP > c:\securParms\securParms.csv
Enter insert buffer size (minimum is 8192) 30720> 8192
IMP-00037: Character set marker unknown
IMP-00000: Import terminated unsuccessfully
Please show me the easiest way to import a text file into a table. How complex could it be to do a simple import into a table using a text file?
We are testing our application against both an Oracle database and a MSSQLServer 2000 database.
I was able to import the data into a table in MSSQLServer database and I can say that anybody with no experience could easily do an export/import in MSSQLServer 2000.
I appreciate if someone could show me how to the import from a file into a table!
Thanks,
Mitra

Not a perfectly framed question. How do you want to load the XML file? Hoping you want to parse the xml file and load it into a table you can do this.
This is the xml file
karthick% cat emp_details.xml

<ENAME>CLARK</ENAME>
