UTL_FILE

[i]Hi,
Is there a limitation to the size of the file that can be generated by UTL_FILE package, Or the limitation of 32k is for the buffer size? In which case, the data has to be written to the output file before the limit is reached, correct?
How to check if the buffer limit has been reached so that there is no data "loss"
Appreciate your help....
Thanks,
Oracle Fan

Help needed in utl_file

Hi,
I have two groups in data model of my report. I am using utl_file in a formula column of report last group.it's working fine.
but my problem is if customer has more than one invoice lines
then all that lines not comes under only particular customer only at a time.
For example my output is coming like this:
Customer address: 3345 LIMITED-STUDIOS : 00033-45 PARR STREETLIVERPOOLCHESHIRE
Invoice Lines: 0001000402106-JUL-07INV 10.47
Customer address: 3345 LIMITED-STUDIOS : 00033-45 PARR STREETLIVERPOOLCHESHIRE
Invoice Lines: 0001000402713-JUL-07INV 10.77
But I am trying to get output like this:
Customer address: 3345 LIMITED-STUDIOS : 00033-45 PARR STREETLIVERPOOLCHESHIRE
Invoice Lines: 0001000402106-JUL-07INV 10.47
0001000402713-JUL-07INV 10.77
I am using fallowing code in my formula column:
function CF_UTL_FILEFormula return Char is
v_file_data utl_file.file_type;
begin
utl_file.put_line(v_file_data,:SEND_CUSTOMER_NAME:SEND_ADDRESS1:SEND_ADDRESS2:SEND_ADDRESS3:SEND_ADDRESS4:SEND_CITY:SEND_STATE:SEND_COUNTRY_DESC:SEND_POSTAL_CODE);
utl_file.put_line(v_file_data,LN1:CF_LOCATION:C_DELIVERY_DATE:INVOICE_NUMBER:TRX_DATE:c_transaction_type:CD_TRX_AMOUNT);
utl_file.fclose(v_file_data);
end;
Please help me how can I do this?

What's the source of your Summary Column? It's not allowed to choose here the formula column in whcih you reference the summary column back. But another column should work.
As alternativ add a formula column in the upper group with
utl_file.put_line(v_file_data,:SEND_CUSTOMER_NAME:SEND_ADDRESS1:SEND_ADDRESS2:SEND_ADDRESS3:SEND_ADDRESS4:SEND_CITY:SEND_STATE:SEND_COUNTRY_DESC:SEND_POSTAL_CODE);
and remove the same line out of the other formula column.

Problems with moving files to ora directory UTL_FILE.PUT_RAW - ORA-29285

hi,
i'm using apex 4.1
i have a procedure which moves my file from apex_application_files to ORA directory.

If i uncomment UTL_FIle.Fopen statement, the error text will be the path name and file name.
Can anyone advise as to what should be done to resolve this on XE. It worked fine on 8i.
I have runcatproc.sql and utlfile.sql also
regards
kunal

Hi
On 8i you would have set the UTL_DIR_PATH parameter
in the init.ora file. Did you do this for your XE
database? I hope you are referring to the UTL_FILE_DIR parameter. I have set this parameter to value *.
Although the better approach would be to
create a directory object for the file path, an
option which was introduced in 9i..
Can you please elaborate me on this. I tried declaring the create directory statement in the package, but that didnt help. I have already created one through sql command line. How can i use this directory as an alternative to utl_file

How to create/delete files from filesystem using PL/SQL ? UTL_FILE?

Greetings,
I will start by explaining what i intend to do.
I have an application made in APEX. This application will have among other purposes the managment of pdf files which will reside in the filesystem.
I have questioned the person in charge to keep the pdf files in the database and not in the filesystem but without success.
So the pdf files reside in the filesystem and there is a record in a database table about them. A table keeps all info about the pdf, their location , size and name, creation date etc.
The APEX application will have a mecanism to allow the deletion of the pdf files if an administrator decides.
So it should be possible for an administrator to schedule the deletion of all pdf files whoe creation date is older than 2008 for example
So, how can i achieve that?
After some research i foudn about the UTL_FILE package which seems to have it takes to perform the task in issue.
My idea was to have a script in the operating system which runs nightly and reads a file containing all file names of the pdf to be erased.
The file which contains the names of the pdfs to be erased will be generated by the database a few minutes before.
If there are no pds files to be erased than the file containing the names will simply be empty
Are there any other viable solutions out there?
And as for opening/creating the file withn the pdf names, i use:
UTL_FILE.FOPEN (
location IN VARCHAR2,
filename IN VARCHAR2,
open_mode IN VARCHAR2,
max_linesize IN BINARY_INTEGER)
RETURN file_type;
And as for writing lines (a pdf name per line ), i use;
UTL_FILE.PUT_LINE (
file IN FILE_TYPE,
buffer IN VARCHAR2,
autoflush IN BOOLEAN DEFAULT FALSE);
is there a better solution?

Greetings,
I have read that link above, some questions still though.
I will provide some more information.
-First the database is in a windows server.
The windows server has a virtual drive mounted as z:\ <-- this points to a directory in virtual machine, i can manually access/create/delete files manually,i tested.
-Second utl_file_dir is defined as * , in t that enough to cover mounted drives? ( i can't change the init.ora and reboot the db right now :( gotta wait.. )
Do i explicitly have to define utfl_file_dir = z: ?
-Third haven't had the chance to test it on linux or any other operating system, assuming a virtual unit is mounted successfully and that the issues above are solved i should be able to operate on any mounted drive whatever the os, right?
Best regards

Problem with UTL_FILE (please see my last post on this thread)

Hi all,
I'm trying to get the code (procedures, functions, etc) of my schemas. I've tried it using DBMS_METADATA.GET_DDL but it fails with many objects. Finally, I'm trying to create a procedure to extract the code.
I've created this two procedures:
CREATE OR REPLACE PROCEDURE spool_code (code IN varchar2, propi IN varchar2) is
CURSOR codigo is
select text from dba_source where name = code and owner = propi order by line;
line varchar2(4000);
BEGIN
open codigo;
loop
fetch codigo into line;
exit when codigo%notfound;
dbms_output.put_line(line);
end loop
close;
END;
CREATE OR REPLACE PROCEDURE ext_codigo is
CURSOR objeto is
select object_name, owner from dba_objects where object_type in ('PROCEDURE','FUNCTION','PACKAGE')
and owner not in ('OUTLN','DBSNMP','SYSTEM','SYS','REPADMIN','PERFSTAT','SPOTLIGHT','MONITOR','PRUEBAS','TOAD')
and status='VALID';
nom varchar2(128);
owner varchar2(30);
BEGIN
open objeto;
loop
fetch objeto into nom, owner;
exit when objeto%notfound;
spool_code(nom, owner);
end loop;
close objeto;
END;
And I'm calling from sqlplus to spool it:
SQL> spool Users_code.sql
SQL> exec ext_codigo;
But it don't bring me results...
where is the problem??
Thanks in advance for your support!

Hi,
yes guys, I've set serverout on using the max limit but, always fails with:
ERROR at line 1:
ORA-20000: ORU-10027: buffer overflow, limit of 1000000 bytes
ORA-06512: at "SYS.DBMS_OUTPUT", line 35
ORA-06512: at "SYS.DBMS_OUTPUT", line 198

ORA-06512: at "SYS.SPOOL_CODE", line 15
ORA-06512: at "SYS.EXT_CODIGO", line 17
ORA-06512: at line 1
I'm working with a 9i version trying to extract the code to migrate it to a 11g.
In order to avoid the buffer error, I've decide use the UTL_FILE package but I'm having another problem: my procedure now is this
CREATE OR REPLACE PROCEDURE spool_code (code IN varchar2, propi IN varchar2) is
CURSOR codigo is
select text from dba_source where name = code and owner = propi order by line;
line varchar2(4000);
out_file UTL_FILE.File_Type;
BEGIN
begin
out_file := UTL_FILE.Fopen('/export/home/oracle', 'Users_code.sql', 'w');
exception
when others then
dbms_output.put_line('Error opening file');
end;
open codigo;
loop
fetch codigo into line;
exit when codigo%notfound;
UTL_FILE.Put_Line(out_file, line);
end loop;
close codigo;
UTL_FILE.Fclose(out_file);
END;
The directory exists and the file too but fails with this error:
ERROR at line 1:
**ORA-29282: invalid file ID**
ORA-06512: at "SYS.UTL_FILE", line 714
ORA-06512: at "SYS.SPOOL_CODE", line 23
ORA-06512: at "SYS.EXT_CODIGO", line 17
ORA-06512: at line 1
any idea? about the reason? The file is a text file on the server:
ls -lrt /export/home/oracle/Users_code.sql
-rw-rw-r-- 1 oracle dba 0 Aug 29 14:43 /export/home/oracle/Users_code.sql

Line size in UTL_FILE

Hi,
Can someone please tell me what is the max. number of characters that can be written using UTL_FILE in Oracle 8.1.7?

Perhaps I should have been more specific; I wanted to know how many characters can PUT_LINE or PUT function take at one time to write. Well, in 8.1.7, it is only 1000 characters on UNIX platform. Though it is not mentioned anywhere so I am not sure if this is OS limitation. However I had to do a lot of trial and error before e finding this out. Hope this would help people on the forum.
Thanks guys for your help. I know I can always count on you all.
Here is the sample code. In this, although, I had defined a buffer of 4000, but it consistently gave me 'WRITE_ERROR' for PUT_LINE or PUT function, until I reduced the buffer size used with these functions to 1000. Alternatively now I will use PUT function recursively and add NEW_LINE character after the entire buffer is read.
declare
vstr varchar(4000);
file_handle UTL_FILE.FILE_TYPE;
begin
select rpad('Testiing',990,'xyz') into vstr from dual;
file_handle := UTL_FILE.FOPEN ('/usr/users/cornwas/workplace', 'a.txt', 'w');
for i in 1..20 loop
UTL_FILE.PUT_LINE(file_handle, vstr);
UTL_FILE.FFLUSH(file_handle);
end loop;
UTL_FILE.FCLOSE(file_handle);

Producing text file from PL/SQL procedure (UTL_FILE)?

Hi,
I need to produce a text file from a PL/SQL procedure. My output should be a little over 38K records and my query has 70 fields. I'd like to separate the fields by pipe delimiters in the text file. I can either concatenate all 70 fields into one variable for each record or send all 70 fields over with a pipe, whichever is easier. It looks like I can't spool within PL/SQL but UTL_FILE might be an option from what I'm reading. Does anyone have any good, simple example(s) to produce a text file using this package in calling multiple fields from a LOOP? Our os is UNIX and db is Oracle 9i.
Also, I've read that UTL_FILE has a record output of 1,023 bytes. Is this for each record line or the whole file size? I belive the max # of characters for each line wouldn't exceed 500 characters. The 38K rows I have for the data set would be well over 1MB. If this is the case, is there a work around to produce a larger text file?
Any suggestions and/or examples would be greatly appreciated.
Thanks,
Eric

Assuming the goal is to create a text file on the database server, you can use UTL_FILE here. Each line can be 1023 characters, but you can have as many lines as you'd like.
Tom Kyte has an example here

How do I use UTL_FILE to insert a large number of fields to a file?

Hi
I am trying to use UTL_FILE for the first time in a Stored Procedure. I need to run a complex query to select 50 fields from various tables. I need these to be inserted into one line in the output file for all rows. Is this possible? My procedure so far is like the following
CREATE OR REPLACE PROCEDURE PROC_TEST IS
output_file UTL_FILE.FILE_TYPE;
BEGIN
FOR query in (SELECT FIELD1, FIELD2, ..........FIELD50)
FROM TABLE A, TABLE B
WHERE A.ID = B.ID
ETC
LOOP
UTL_FILE.PUT_LINE(output_file, <put all 50 fields for all records into file> );
END LOOP;
UTL_FILE.FCLOSE (output_file);
EXCEPTION
WHEN NO_DATA_FOUND THEN
NULL;
WHEN OTHERS THEN
UTL_FILE.FCLOSE_ALL;
RAISE;
END PROC_TEST;
Do I need to define 'query' (after the FOR) anywhere, also please advise with how I put all of the fields into the file.
Thanks
GB

Thanks Steve,
I have the UTL_FILE working fine now.
I have other queries to run and conditions to apply in the same procedure, and I need to schedule via Enterprise Manager, therefore using UTL_FILE in a procedure seemed the best option. I looked up Data-pump but this seems to be an 11g feature, and we are still on 10g therefore I will not be able to use it.
Thanks for your help.

How to read a specific value or a portion of text using utl_file.

hi,
I have a small requirement which goes as follows. I have a text file which is a resultof the sql query and it contains 16 columns as PIPE delimited text . I am using the UTL_FILE package concept to read the data. In general when we use the UTL_FILE.GET_LINE we read the entire line of text. But i need to read the 10th column of the query or the PIPE delimited text .
Please advice.
My query goes something like this:
declare
f utl_file.file_type;
s long;
c number := 0;
begin
f := utl_file.fopen('ABC_EXTRACTS','sample1.txt','R');
loop
utl_file.get_line(f,s);
insert into s values (s);
c := c + 1;
end loop;
exception
when NO_DATA_FOUND then
utl_file.fclose(f);
dbms_output.put_line('No. of rows inserted : ' || c);
end;

Why don't you use varchar2 instead of long data type. I doubt you can read a portion from a file using utl_file but after doing the fetch you can do substring over the varchar2 variable and retrieve just the 10th column.
sample sql:
If your DB is 10g or higher, you can use the below regular expression to retrieve value based on your need.
PRAZY@11gR1> select regexp_substr('111|222|333|444|555|666|777|888|999|000|aaa|bbb|','[^|]+',1,10) from dual;
REG
000
Elapsed: 00:00:00.00Btwn, if the text file has fixed number of columns at all time, why don't you use a external table instead?

Prazy

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.

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.

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.

Hello,
What exactly are you trying to do? Here I got 2 examples for you , replace with your directory name and pick right option for 'a' (append) or 'w' (write) or 'R' (read).
To read from a directory_ . This will read an existing file 'customer.txt" from the directory
{code}
CREATE OR REPLACE PROCEDURE .file_upload

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
