About utl_file

Hi,
I have one excel file as follows;
Insured Policy # Attn to Fax
Spring Industries, Inc. WC-000008-03 Juengermann, Allen (805) 644-1842
I want read only policy # from this file to check the policy number is exists in table or not.
If some body worked on this then please help me.
Thanks in advance.

You have the architecture the wrong way around. An Excel spreadsheet should be the client and not the server.
If the data in Excel is to be shared and used by a number of database users, then that spreadsheet must be moved from Excel into Oracle.
Excel is not a data server that can share spreadsheet data to a number of concurrent users. Oracle is.
If the spreadsheet data is not a "multi-user data set", then Excel is indeed the client. A client that wants to check whether the policy # exist in the database.
In this case you need to write an Excel macro (using VB for Applications?) that opens an ODBC connection to the Oracle server and run a SQL (with bind variables) to determine if the server knows about that policy or not.
UTL_FILE has no role to play in any of this.

1) The problem I faced is that when I perform INSERT sql for the new data, it can be successfully be inserted into both tables TEST_REC_TABLE and TEST_TABLE, but it just does not write to the text file.
2) However, when I just execute the procedure I will get XX for the input data as it is NULL. This XX data will then be seen in TEST_REC_TABLE as "XX" record and Test_Table.txt as "Inserted XX @ 10-01-2014 04:56:06 PM". UTL_FILE did write to textfile so my guess is that it could be due to my poor understanding of logic in the checking of the input data for NULL. Tried but I am still clueless, thanks for pointing out the issue.

> 1) I'm just testing and learning here with trigger insert...
Good. In that case its just a wrong choice that you have decided to write to a file from trigger. Oracle base is a good site. They have examples too. Please check that ORACLE-BASE - Database Triggers Overview.
> 2) How should I do then?
Just create the object one time
CREATE OR REPLACE DIRECTORY FILEDIR AS <path>
The path should be a location in your server where oracle is installed.
> 3) How should I do then? Use this ?

Don't do any thing. Just remove the exception handling. Don't handle unknown exceptions. If at all you want to handle them for logging purpose RAISE it at the end like this.

    raise;
And about exception handling one of the forum member BluShadow has written a nice article PL/SQL 101 : Exception Handling. That would be a nice read.

Line length in UTL_FILE

HI.. sorry for basic question but....
1- I want to create a file from database.
2- The length of lines to append to the file is 1300
3- when I try to close the file or make fflush to the file
(write lines into the file), exception utl_file.write_error
is fired.
4- when the length of the line is 750 (i,e) that's not occurs
WAY???
What is te maximun length for the line to append???
May be concern of Operating System variable??
THANK's and excuseme for my regular english.

1) Read about utl_file.put (tells you the line max)
2) Doc for the rest of UTL_FILE

Extracting XML Data to a flat file

I have an application which is puting an XML string into a field in the database... now my problem is that I have to extract that information and put it in either 1. a flat file, or 2. a seperate table containing a column for each XML attribute... Does anyone know of the best way to approach either solution?
cheers.

And your Oracle version is?
There are many different ways to put something into a file. How about UTL_FILE?http://www.psoug.org/reference/utl_file.html
How to get it out of the table in the first place?
I usually try a SELECT statement. They seem to work.
PS: Databases don't have fields ... table's don't either. Check your verbiage.
Try looking of the word "FIELD" in the Oracle docs. Then try "COLUMN."

Writing from a BLOB to a FIle on the Server

I need to be able to save the data from a BLOB column to an external file on the server, preferably in a temporary directory. Afterwards I will add a header to the file and send to the web client. I believe I know how to add the header. However, everything I have read in DBMS_LOB or UTIL_FILE describes saving a BFILE or CLOB to a BLOB, but not the reverse. Can you save from a BLOB to an external file on the server? The processing must be done on the Server.
I have been able to select TEXT from a VARCHAR column and save to a file on the server but unable to select a BLOB and save to the file.
Thank you for your help,

UTL_FILE would be the correct thing to use, but I seem to recall that it didn't work for binary files. It apparently adds CR LF data into the files when written. I am not sure if this has changed recently or not. You might try posting in the database or PL/SQL forum about UTL_FILE.

HOW TO RETRIEVE A LONG RAW COLUMN FROM A TABLE AND WRITE TO OS FILE

Good evening.
Please how can I read a long raw datatype from a table and insert into an operating system file using PL/SQL.
Thank you.

What does this have to do with LONG RAW? It is about UTL_FILE and not especially great code.
The question is how to retrieve and write LONG RAW and that is quite a different matter.
First you must convert it to BLOB.
http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:13213885403654
Then you can write it out to the file system

Move file/Client_host

Hi all,
I want to move file from client to server using Oracle Apex.
I am using wwv_flow_file table to load the content and drop into the server directory
but i have been instructed not to use this instead use only PL/SQL to do this task.
I know about UTL_FILE.FCOPY but its parameter SRC_LOCATION is a hinderance as its asks for Directory rather than File Path.
Do you guys have any solution if i can get the same functionality of CLIENT_HOST command in APex.

Hello,
Do you need the file to be in the database or on the server?
I don't exactly know what you mean with, you can't use the wwv_flow_file table? APEX is build in plsql, so you're using plsql?
If you would use XMLDB you could just drag-drop into a folder of the database.
Regards,
Dimitri

How tor ead blob in oracle

Is there a way to read/extract blob and see contents of it in oracle? Preferabaly using anonymous pl/sql block?

you can read about utl_file here:
http://download.oracle.com/docs/cd/E11882_01/appdev.112/e10577/u_file.htm#ARPLS70896
after that you will use it in a cursor loop over you table.
could you post your table structure and some sample dml?

Instead you use the SqlLoader you can use too the UTL_FILE
package. This package come with oracle and have to be executed
in the ORANT\RDBMS\ . After created this package you can read
and write file from PL/SQL programs. Don't forget it to insert
the parameter in the IntiSid.Ora " utl_file_dir= * " . Read the
documentation about Utl_file .
I prefer Utl_file because you can manage the data before insert
in the Database. But the Sql Loader is too a good toll.

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?
thanks all.

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

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

Oracle Security : what do you think about the following policy violation ?

If you install OEM10, you will be able to see if you violate some security guidelines :
Interresting is revoking UTL_FILE from public, which is critical. Also revoke UTL_TCP and UTL_SMTP. This is going to upset an expert I know...
Take care about the failed login attempts. If you set it to 10 to the default profile, and if your DBSNMP password is NOT the default password, then Oracle will lock your account after node discovery!
In Solaris, you can disable execution of the user stack with the system parameters set noexec_user_stack=1
set noexec_user_stack_log=1. I did not find how to do it on AIX. However, those settings may have side effects.
About the ports, it complains about open ports, even if this is the port oracle listener is using! Simply ignore most of the violations there.
About JAccelerator (NCOMP), it is located on the "companion" CD.
Ok, Waiting for your feedback
Regards
Laurent

Interresting is revoking UTL_FILE from public, which is critical. Also revoke UTL_TCP and UTL_SMTP. This is going to upset an expert I know...Okay, as this is (I think) aimed at me, I'll fall for it ;)
What is the point of revoking UTL_FILE from PUBLIC? Yes I know what you think the point is, but without rights on an Oracle DIRECTORY being able to execute UTL_FILE is useless. Unless of course you're still using the init.ora parameter
UTL_FILE_DIR=*which I sincerely hope you're not.
As for UTL_SMTP and UTL_TCP, I think whether a program is allowed to send e-mail to a given SMTP server is really in the remit of the e-mail adminstrator rather than the DBA.
Look, DBAs are kings of their realm and can set their own rules. The rest of us have to live with them. A couple of years ago I worked a project where I was not allowed access to the USER_DUMP_DEST directory. So every time I generated a TRC file I had to phone up the DBA and a couple of hours later I got an e-mail with an attachment. Secure yes, but not very productive when I was trying to debug a Row Level Security implementation.
I have worked on both sides of the DBA/Developer fence and I understand both sides of the argument. I think it is important for developers to document all the privileges necessary to make their app run. Maybe you don't have a better way of doing that than revoking privileges from PUBLIC. Or maybe you just want to generate additional communication with developers. That's fine. I know sometimes even DBAs get lonely.
Cheers, APC

Writing large xmltype data to UTL_FILE and setting max row per file

Hey Gurus,
I am trying to create a procedure (in Oracle 9i) that writes out xml data I have created into several xml files (file would probably be to large for one xml file output...I am doing this for 270,000 rows of data), setting the max rows to 1000 rows per file. I know one would have to create a looping contsruct to do this but I am just not adept enough in PL/SQL to figure it out at the moment.
So essentially their would be some sort of loop construct and substr process that creates a file after looping through 1000 rows and then continues the count and creates a another file until all 270 xml files are created. Simple enough right...lol? Well I've tried doing this and haven't gotten anywhere. My pl/sql coding skills are too elementary I am guessing. I've only been doing this for about three months and could use the assistance of a more experienced person here.
Here are the particulars...
This is the xmltype view code that I used to create the xml data.
select XMLELEMENT("macess_exp_import_export_file",
XMLELEMENT("file_header",
XMLELEMENT("file_information")),
XMLELEMENT("items",
XMLELEMENT("documents",

XMLELEMENT("external_reference"),
XMLELEMENT("processing_instructions",

))))from macess_import_base WHERE rownum < 270000))))AS result

I also would like to use UTL_FILE to achieve this functionality in the procedure.

UTL_FILE, Extra CRFL's, possible OS interpretation problem.

Greetings,
DISCLAIMER:
I am an oracle noob so if I make a mistake in forum etiquette or have not checked all available documentation or have made an assumption that is incorrect ( or noobish ) or am unaware of a tool better suited to the task I am trying to accomplish..
Please don’t flame me, I am learning. Give me constructive replies and I will learn, I promise.
My environment: 10G XE DB running on Server 2k3. Developing in SQLDEV 1.54
I am attempting to dump the contents of a CLOB to a file on the OS disc. Due to formatting restrictions, the contents of the file written to disc must be EXACTLY the contents of the CLOB, character per-per character, verbatim.
Here is an example anon block that will give you the essentials of the way I am attempting to accomplish this:
DECLARE
l_clob CLOB ;
l_output_file utl_file.file_type;
BEGIN
l_clob := 'Hello my name is George!' || chr(13) || chr(10) ;
l_clob:= l_clob || 'Would you like to play a game?' || chr(13) || chr(10);
l_clob := l_clob || 'It will be fun, I promise..' || chr(13) || chr(10);
dbms_output.put_line( dbms_lob.getlength(l_clob));
l_output_file := utl_file.fopen( TEST_DIR' , 'test.txt' ,'W', max_linesize=> 32767 );
utl_file.put( l_output_file , l_clob );
utl_file.fflush( l_output_file);
utl_file.fclose( l_output_file );
utl_file.fclose_all;
END;
Here you can see where I put a few lines into my clob, I manually append the CRLF using the CHR function, since I cant accurately reproduce a non-printable character in a string value. This is important because the Clob I am attempting to write to disc contains CRLF’s as part of its data, these must be preserved. Also note that I am writing this to the file using utl_file.PUT not PUT_LINE, again, because the disk file must be the clob verbatim, I cant use put_line because it adds a “new line character” at the end of the data it writes.
Ignore the DMBS_OUTPUT line , I will get back to that in a bit.
I execute this bit of code and get a file text.txt. What I expected to see was:
“'Hello my name is George!
Would you like to play a game?
'It will be fun, I promise..”
What I actually got was:

Looking at this in notepad++ we can expose the non-printable chars:
!http://i594.photobucket.com/albums/tt22/GargleSpam/Temp002.jpg!
Using notepad ++ we can see that an extra CR ( CHR(13)) has been pre-pended to the CRLF. We can confirm this is not an artifact of viewing this in notepad by looking at the file size of the output file and comparing it to the size of the clob.
The DBMS_OUTPUT line indicates ( in my test case) clob size of 87 characters. If you take the time to count you will see this is correct. 81 printable characters that we see, and the 6 non-printable chars to accomplish the CRLF’s.
However if we look at the file size:
!http://i594.photobucket.com/albums/tt22/GargleSpam/Temp003.jpg!
So that’s 87 + our 3 “ninja ” CR’s.
For my purposes this is a deal-breaking problem. The contents of my output file must be exactly the contents of my clob, byte for byte. So this extra CR is a big big problem.
Where is it coming from? I started thinking about the “new line character” that the PUT_LINE procedure uses and, had a hunch that perhaps since the DB is OS independent, it might be passing one of the non-printable chars to the OS as “new line” and letting the os worry about what that means on disk. With that in mind I did some further testing:
DECLARE
l_clob CLOB ;
l_output_file utl_file.file_type;
BEGIN
l_clob := 'Incoming lf->'|| chr(10) ;
l_clob:= l_clob || 'Incoming cr->' || chr(13);
clob:= lclob || 'Incoming CRLF->' || chr(13) || chr(10);
l_output_file := utl_file.fopen( TEST_DIR' , 'test.txt' ,'W', max_linesize=> 32767 );
utl_file.put( l_output_file , l_clob );
utl_file.fflush( l_output_file);
utl_file.fclose( l_output_file );
utl_file.fclose_all;
END;
This code results in:
!http://i594.photobucket.com/albums/tt22/GargleSpam/Temp004.jpg!
Looking at this it becomes obvious that the CHR(10) is being written to disc as TWO characters ( CR LF). So my assumption must be correct, that the DB is passing CHR(10) to the OS as “newline” and the OS ( Windows in my case ) is interpreting this as ‘CRLF.’
This makes sense since it seems to be widely known ( though not to me , I am shaky on this part ) that “newline” in unix is just CHR(10), and in windows its CHR(10)||CHR(13).
So I seem to have isolated my problem. Now finally my question.. How to I get around this?
Google searches and searches on this forum yeilded only marginal help, something about passing this file through an FTP server.. ?. The only marginal help was in post # 3298335. Nothing that really answers my question though.
Is there a setting my DBA can set to change this behavior? Is there a different way ( PLSQL) to write the file that might mitigate this? Don’t say put the DB on unix, that’s not an option.
Let me know what you think…

Hi,
Also you should check that the directory name is enclosed between '. TEST_DIR is an Oracle directory object that maps a real directory path in the filesystem (check privileges).
Like:
DECLARE
    l_clob CLOB;
    l_output_file utl_file.file_type;
BEGIN
    l_clob := 'Hello my name is George!' || CHR(13) || CHR(10);
    l_clob := l_clob || 'Would you like to play a game?' || CHR(13) || CHR(10);
    l_clob := l_clob || 'It will be fun, I promise..' || CHR(13) || CHR(10);
    dbms_output.put_line(dbms_lob.getlength(l_clob));
    l_output_file := utl_file.fopen('TEST_DIR', 'test.txt', ' W', max_linesize => 32767);
    utl_file.put(l_output_file, l_clob);
    utl_file.fflush(l_output_file);
    utl_file.fclose(l_output_file);
END;Tip: to post formatted code you must enclose it between {noformat}{noformat} tags (start and end tags are the same).
