How to read a tab seperated data from a text file using utl_file

Hi,
How to read a tab seperated data from a text file using utl_file...
I know if we use UTL_FILE.get_line we can read the whole line...but i need to read the tab separated value separately.....
Thanks in advance...

It is then up to you to split that string up (search for split string on this forum for methods) into it's individual components.
If the text file contains a standard structure on each line, i.e. it is a fixed delimited structure, then you could use external tables to read the data instead.

How to read HTML files using UTL_FILE

HI Hareesh,
i have gone through that blog.
i tried it...but i am getting mapping error no receiver determination fond because there are so many excel files.
my data is available on sharedString.xml but also it is in not same order.
i have no clue how to handle this part form the blog.
"This way our mapping will receive all data from the sheet in an XML format. The only thing that's left is to create an XSD file from the XML file we received in order to be able to use it in the mapping and as our Service Interface and we can proceed with mapping. As you can see from the sheet.xml files all the data is placed with column name and row number so it's not that difficult to map it to an table type format using the Message Mapping only (no java, abap mapping required)."

How to append a character using UTL_FILE pkg

A table with student_id, student_name and date_of_join.
create table student(std_id varchar2(10),std_name varchar2(20),std_doj date);I am loading the data from the below flat file using UTL_FILE package
101   ron   04081999
101   ron   01081996
102   ram   05082000
102   ram   12101999
103   fin   06082001
104   gin   07082002
105   gem   08082003I am using a procedure to load the data into table using UTL_FILE package
Students with id's 101 & 102 have two joining dates as they have registered for two courses. In flat file there is no change in std_id but I have to append a character "C" to those who have registered for the second course.
I have to append a character to std_id column. for eg: After loading the result what I am expecting is
std_id          std_name          std_doj
101          ron               04081999

105             gem               08082003          Can you please give me an idea on how to get the above result using UTL_PACKAGE in the procedure?

It has nothing to do with UTL_FILE. In your load procedure you are looping through the file line by line, right? SO you need to :
DECLARE
    prev_std_id number;
BEGIN
    LOOP
      read a line
      parse it into std_id, std_name and std_doj
      IF std_id = prev_std_id
        THEN
          std_id := std_id || 'C';
        ELSE
          prev_std_id := std_id;
      END IF;
      insert row
    END LOOP;
END;SY.

i would like to use ult_file only and also can you let me know to read the text file and place its contents in tmp_emp table?

Are you trying to read the contents of the file into the local variable? Or write the contents of the local variable to the file?
Your text talks about reading the file. And you open the file in read mode. But then you call the UTL_FILE.PUT_LINE method which, as SomeoneElse points out, attempts to write data to the file. Since the file is open in read-only mode, you cannot write to the file.
If the goal is really to read from the file, replace the UTL_FILE.PUT_LINE calls with UTL_FILE.GET_LINE. If the goal is really to write to the file, you'll need to open the file in write mode ('W' rather than 'R' in the FOPEN call).

Can't read text file using UTL_FILE

Hi All,
how can I read notepad file using UTL_FILE package.I have specified the UTL_FILE_DIR in the init.ora file.My objective is to when a button is clicked, the contents of the file will display in a text item.Here is my code written in WHEN_BUTTON_PRESSED trigger.
DECLARE
     file_handle UTL_FILE.FILE_TYPE;
data_line Varchar2(100);
BEGIN
     file_handle := UTL_FILE.FOPEN('E:\vimal','abc.txt','R');
          message('directory created');
     UTL_FILE.GET_LINE(file_handle, data_line);
     :block2.t1 := data_line;
     UTL_FILE.FCLOSE(file_handle);
END;

Why don't you use text_io? Don't forget that UTL_FILE is reading directories from the database point of view. The E drive for the database is a different E then on your client pc. I presume your database is on a different computer. Are you getting any errors?

Error writing data in a flat file using UTL_FILE feature

Hi All,
I have written a package which fetches data from four different cursors and inserts into a temporary table.
Now this temporary table is used to write data in a file using the UTL_FILE feature.
fhandler :=
UTL_FILE.fopen (l_path,'Demand_Transactions_'
|| TO_CHAR (SYSDATE, 'YYYYMMDDHH24MI')
|| '.txt',
'w',
max_linesize => 32767
This table has 62593 records and when it starts writing data into the file from the table it errors out after writing 30045 records with the error - ORA-01722: invalid number.
Can anyome please advise me is it because of the max_linesize => 32767. If not then what can be the possible reason.
Any help in this would be highly appreciated.

Shruti

The error would indicate that you have a character to number conversion going on somewhere but the characters are not numeric so it's failing that conversion.
This doesn't sound like a UTL_FILE issue, but more to do with how you are building up your strings to output to the file.
You would need to show us your code that builds up the lines you are writing out, with details of the datatypes of any of the columns/variables included in that.

Issue while accessing a file using UTL_FILE

Hi,
My requirement is to check for the existence of a file in the file system(apps tier) and then launch a conc program to load the data.
There is a separate DB tier.
I am trying to use UTL_FILE.fopen to indirectly see if the file exists
and then proceed and I am trying to use UTL_FILE.fopen for that.
The file is placed in the apps tier. I have created a directory in the database with the path and using that in the UTL_FILE.FOPEN call.
However I am getting the following error. ORA-29283 - An attempt was made to read from a file or directory that does not exist, or file or directory access was denied by the operating system.
What could be the issue here? Is there anything that I need to do after creating the directory?.
Thanks,
Balaji

/Pl post details of OS, database and EBS versions.
Are the Apps and DB servers physically separate ? If so, the directory on the Apps server where the file resides will have to be visible/updateable to the DB server in order for UTL_FILE to be able to read/write to it.
HTH
Srini/
The apps and db servers are separate. EBS version is 11.5.10.2 and the OS is unix.
How do I make the directory in apps server visible/updateable to the DB server?. I have created a directory in the database with the location of the file in apps tier.
Thanks for your quick reply

Creating Error log files using UTL_FILE package on a remote machine

Database Version: 10g Release2
OS Platform: Sun Solaris
I have been asked to log errors to OS files rather than tables. So, i wanted to use UTL_FILE package. But the client doesn't want to store these files on the same server where the database is running(as specified in UTL_FILE_DIR). Is there a way i could get these files created on a remote machine(client).

I believe what others are suggesting is that your stored procedure continues to log to a table and a separate process be created that runs on the machine you want the file to be created on which reads the log table and writes to a log file.
If that is not an option, can you expose the directory on the remote machine you want to write the file to as a file share that can be mounted by the database server? If you can, you could write errors there using UTL_FILE. However, it would probably be a bad idea. If you're logging an error already, that implies that something has gone wrong. Making an error logging process dependent on a remote server being available and properly mounted with appropriate privileges at the instant the error occurs just creates more sources of failure that would prevent you from logging an error, which would prevent you from being able to debug the problem or even know it existed without a report from a user.

Having problem in recognising file using utl_file package..

Hi,
I am using utl_file utility to read the CSV file, utl_file.fopen function is useed to open file. This fopen function has three input parameters, second parameter is file name. My problem is that, i have to read file on daily basis. File name will be like:- DDMMYYYYHHMISS. Last six characters are for hour minute second of the file generation time. If the name has only DDMMYYYY then I can give the file name like TO_CHAR(SYADATE,'DDMMYYYY'), because on a particular date its same for the whole day. But hours, minutes and seconds will be of the time when the file is generated, it may be different for different days. In this condition how can I standardize the value for file name parameter in fopen function.
Thanks in advance.

Regards,
Vissu.....UTL_FILE just reads data from the file. It has no concept of what could be a "header" or "body" or "records" or "footer" or any other data based concept. If you want to skip lines of a file, you will just need to read them using UTL_FILE and ignore them.

Unable to remove *.log files using utl_file.fremove

Hi,
I want to remove .log files using the below command
I want to remvoe all the *.log files but its remvoing only one .log file
utl_file.fremove(location => dir_name, filename => log_file_name);
Any help will be needful for me

In the documentation for your unknown version of oracle you can view the definition of utl_file.fremove.
Everywhere it states utl_file.fremove removes a file, not 1 or more, and the documentation doesn't discuss the use of wildcards.
It seems like the question could have been prevented by reading docs (which almost no one here does), and you need to use Java to address your requirement.
Personally I wouldn't misuse Oracle to perform O/S tasks.
