Dbms_lob.LOADFROMFILE()

What are the types, parameters and syntax of this LOADFROMFILE function ??
Tx in advance,
Xavier

This actually a procedure. The information you seek can be found in the "PL/SQL Supplied Packages Reference" guide.

Dbms_lob.loadfromfile help

sorry in advance if this is basic - SQL developer virgin here . . .
Using the examples in this document
http://download-west.oracle.com/docs/cd/B14117_01/appdev.101/b10840/mm_uses.htm
specifically the code:
INSERT INTO soundtable(id, sound) VALUES (1, EMPTY_BLOB());
COMMIT;
DECLARE
f_lob BFILE := BFILENAME('AUDDIR','chimes.wav');
b_lob BLOB;
Lob BLOB;
Length INTEGER;
BEGIN
SELECT sound INTO b_lob FROM soundtable WHERE id=1 FOR UPDATE;
-- Open the LOBs.
dbms_lob.open(f_lob, dbms_lob.file_readonly);
dbms_lob.open(b_lob, dbms_lob.lob_readwrite);
dbms_lob.loadfromfile
(b_lob, f_lob, dbms_lob.getlength(f_lob));
-- Close the LOBs.
dbms_lob.close(b_lob);
dbms_lob.close(f_lob);
COMMIT;
-- Select the LOB:

DBMS_LOB.CLOSE (Lob);
END;
2 questions for anyone who has done this before or has an opinion:
1) In the initial insert -- INSERT INTO soundtable(id, sound) VALUES (1, EMPTY_BLOB()); -- if the value for the column "id" is sequence.next_val I could end up with an "id" of 3012 for example:
so how would I find out what value the "id" is before doing the next step:
SELECT sound INTO b_lob FROM soundtable WHERE id=1 FOR UPDATE;
I would have to do:
SELECT sound INTO b_lob FROM soundtable WHERE id=<whatever_was_generated_by_the_sequence> FOR UPDATE;
and if there are 10 people inserting at about the same time, how the heck am I supposed to know which "id" goes with which content file?
any help is appreciated

You can use the returning clause to store the generated sequence value that was inserted into id into a variable, then reference that variable in the rest of your code, as demonstrated below.

Yes. The column clobcol (in the SELECT in your example) should be set to empty_clob() or already contain a CLOB, before selecting the column value into the local variable. The example in the DBMS_LOB documentation page is misleading as it does not mention this.
Note also that it is best to use dbms_lob.getlength to establish the value for
the amount parameter.
Hope this helps others searching for information on this - I have spent some painful hours working this out!

DBMS_LOB.loadfromfile don't work?

I have a word doc file, I write a stored proc using DBMS_LOB.loadfromfile to load it into a BLOB record.
-the DBMS_LOB.getlength successfully got the length
-but when I use form ole container to show it....the ole container show nothing.
-if I use initialize_container ... it works....why?
my stored proc :-
PROCEDURE XXinsert_file AS
lobd BLOB;
fils BFILE := BFILENAME('UPLOAD', 'A1.TXT');
length integer;
BEGIN
-- update ole_container set ole_content = empty_blob() where container_id = 'CH050100001';
SELECT ole_content INTO lobd FROM ole_container
WHERE container_id = 'CH050100001' for update;
dbms_lob.fileopen(fils, dbms_lob.file_readonly);
length := dbms_lob.getlength(fils);
dbms_lob.loadfromfile(lobd, fils, length);
update ole_container set file_length = length where container_id = 'CH050100001';
dbms_lob.fileclose(fils);
COMMIT;
END XXinsert_file;

Forms wraps files in a larger structure before storing them as blobs. So in Forms you can only read files that were loaded through Forms, and using dbms_lob you can only read files that were loaded through dbms_lob.

Use dbms_lob.loadfromfile to handle chinese character

Hello,
I have a database with NLS_LANG=TRADITIONAL CHINESE_HONG KONG.ZHT16BIG5
There is a table with clob type column.
I've tried to use dbms_lob.loadfromfile to load file content into the clob type column.
But the result is that no matter the file is english or chinese character, the column's content will become "monster".
Is there any method to solve this problem ?
Can anyone help ?
Rgds,
Edward

Hi, it's me again.
I just want to share my experience and hope that it can help someone and someone can help me !
I've created a database with UTF8 as my character set.
With session's character set = UTF8, when I tried to use dbms_lob.loadfromfile to load data into clob column from a file with chinese character content. What has been stored is "monster" character. I know that it's because bfile is with binary type and will not do character set conversion when loadfromfile is being used.
I've tried the other way, I use dbms_lob.read to read the file and use utl_raw to convert it to UTF8 character set and store it in a varchar2. It works !
But what I want is to store the chinese character into the clob column.
I've tried to use the following option but still fail :
- convert (it's seems that has no effect)
- utl_raw.translate (it always get oracle error, I've use this as : utl_raw.translate(RAW, 'UTF8', 'UTF8'))
- utl_raw.convert
Hope that some have experience can help me !

DBMS_LOB.LOADFROMFILE ignores new lines

Hi All,
I am using UTL_FILE.put_line for creating a text file. However when i try to load it into a blob, all new lines are ignored and text is displayed in one line.
Any idea about this?

Bill,
this is an Oracle Forms forum and your question is database related. I suggest to try the database forum here on OTN.

FILE_LOAD is a folder on the database server(unix).
I have also tried to give the full path on the unix databse server instead of FILE_LOAD directory but then it gives error ora-22285.
while executing this procedure I am getting the error ora-22288(Invalid file or directory).
But this occurs randomly
For instance i tried to attach a pdf file with the name cross.pdf ,it gave me the above error and when i renamed the file as Cross.pdf it attached successfully.
The error comes whilke executing the statement dbms_lob.fileopen(f_lob,dbms_lob.file_readonly);
Please guide on the above issue.

FILE_LOAD is a folder on the database server(unix).
I have also tried to give the full path on the unix databse server instead of FILE_LOAD directory but then it gives error ora-22285.The first argument to BFILENAME is the name of a directory object, as found in the directory_name column of all_directories. That is not the same thing as a folder name, which is found in the directory_path column of all_directories. Look up [CREATE DIRECTORY|http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/statements_5007.htm#sthref6211] in the SQL Language manual for a description of Oracle's directory objects.
If you have problems with this, post the results of
SELECT *
FROM all_directories;It might also be useful to see the Oracle "CREATE DIRECTORY" command that was used.
As you probably noticed, this site compresses white space by default.

Need help in using dbms_lob.read

I need to upload a file into an Oracle table into a Blob column. The file name along with the file contents are all in one BLOB column.
Once that is done I need to read from the file and extract the file contents and load it into a staging table.
File being uploaded is a *.CSV* file.
E.g. Of the .CSV file is: ABC.csv file and its contents will look like:
1,Hello,Nisha
2,Hi,Ravi
3,Bye, Rahul
Etc…..
Therefore the table containing the BLOB column will contain:
File Creation_date
ABC.csv 09/11/2009
How can I read a file from the BLOB column and upload into a staging table?
Final Staging table should look like:
Record Number Greet Name
1 Hello Nisha
2 Hi Ravi
3 Bye Rahul
I think I am suppose to use dbms_lob.read, but I am not really sure how to use it. If there is any script, kindly mail me the same.
Thanks....

Nisha,
Check this example (test) and see if it can be any help. I have utl_file and sqlldr
First Method -- I loaded alert.log successfully and you can imagine how big this file can be (5MB in my test case)
create table t1clob
( clob_text clob);
CREATE OR REPLACE DIRECTORY DIR AS '/path_to_csv_file/;
DECLARE
   clob_data   CLOB;
   clob_file   BFILE;
BEGIN
   INSERT INTO t1clob
   VALUES (EMPTY_CLOB ())
   RETURNING clob_text INTO clob_data;
   clob_file   := BFILENAME ('DIR', ABC.csv');
   DBMS_LOB.fileopen (clob_file);
   DBMS_LOB.loadfromfile (clob_data,
                          clob_file,
                          DBMS_LOB.getlength (clob_file)
   DBMS_LOB.fileclose (clob_file);
   COMMIT;
END;Second Method: Use of Sqlldr
Example of controlfile
LOAD DATA
INFILE alert.log "STR '|\n'"
REPLACE INTO table t1clob
   clob_text char(30000000)
)Hope this helps.

How to insert 10 files from a directory to database,can i use dbms_lob??

Hii
I want to load 10files in my local drive into a table...how to do this.I'm able to do this individually using dbms_lob.loadfromfile and bfil but ,I want to copy all the files i that drive at time to my table...Is there any way to do this..?

Okay... Here is some sample code that will help you store the files in binary format into db tables.
create table t_blob(bid integer, blbdata blob);
select * from t_blob;
create or replace directory ext_tab_dir as 'C:\Oracle\ExtTab_Dir';
grant read, write on directory ext_tab_dir to priya;
declare
      src_file bfile;
      dest_file blob;
      len_file pls_integer;
begin
      src_file:=bfilename('EXT_TAB_DIR','XML.doc');
      insert into t_blob values(1,empty_blob()) returning blbdata into dest_file;
      select blbdata into dest_file
        from t_blob
       where bid=1 for update;
      dbms_lob.fileopen(src_file,dbms_lob.file_readonly);
      len_file:=dbms_lob.getlength(src_file);
      dbms_output.put_line(len_file);
      dbms_lob.loadfromfile(dest_file,src_file,len_file);
      update t_blob
         set blbdata = dest_file
       where bid = 1;
      dbms_lob.fileclose(src_file);
end;
/I haven't used the wrap utility yet, so not much hands on with it. I guess the wrap utility at the OS level. Not sure if it will work at SQL prompt.

Using dbms_lob to load image into table

I am trying to load a set of images from my DB drive into a table. This works fine when I try to load only 1 record. If I try to load more than 1 record, first gets created but I get this error, and it doesn't load the images for the rest of them.
ORA-22297:     warning: Open LOBs exist at transaction commit time
Cause:     An attempt was made to commit a transaction with open LOBs at transaction commit time.
Action:     This is just a warning. The transaction was commited successfully, but any domain or functional indexes on the open LOBs were not updated. You may want to rebuild those indexes.
Am I missing something in the code that's needed?
in_file UTL_FILE.FILE_TYPE;
bf bfile;
b blob;
src_offset integer := 1;
dest_offset integer := 1;
CURSOR get_pics is select id from emp;
BEGIN
FOR x in get_pics LOOP
BEGIN
insert into stu_pic(id,student_picture)
values(x.id,empty_blob()) returning student_picture into b;
l_picture_uploaded := 'Y';
bf := bfilename('INTERFACES',x.student_id || '.' || p_image_type);
dbms_lob.fileopen(bf,dbms_lob.file_readonly);
dbms_lob.open(b,dbms_lob.lob_readwrite);
dbms_lob.loadBlobFromFile(b,bf,dbms_lob.lobmaxsize,dest_offset,src_offset);
dbms_lob.close(b);
dbms_lob.fileclose(bf);
EXCEPTION when dup_val_on_index then null;
END;
END LOOP;
END;

There are two methods you can use.
1. Create an external table with those images(BLOB column) and then use that external table to insert into another table.

DBMS_LOB.close(v_src_blob_locator);
COMMIT;
--id=1 is created with Winter.jpg populated in BLOB_COL and CLOB_COL is empty.
END;Now user this code to create a procedure with parameter and use that in loop.

DBMS_LOB.FILEOPEN(dir, fname) gives non-existent dir or file error

Hello!
I've been trying to load an image file into the oracle database using the DBMS_LOB loadfromfile procedure. In order to do this, I first have to open the appropriate file which I do using
temp_bfile := bfilename('temp_dir', in_filename);
where in_filename is a string having the appropriate filename. and 'temp_dir' is a directory object created as follows:
CREATE DIRECTORY temp_dir AS 'F:\';
Next when I do a
DBMS_LOB.FILEOPEN(temp_bfile, LOB_READONLY);
I get an exception ORA-22285:non-existent directory or file.
What am I doing wrong? Is the way I've created the directory object correct. I work on an NT machine.
Mona

Not sure if the UTL_FILE package is the same but if you don't set the "utl_file_dir" variable in the INIT.ORA file prior to calling the FOPEN procedure you will get a similiar error. There may be an equivalent parameter for the DBMS_LOB package.

Any feedback would be really appreciated. Thanks.

I assume thats when the ORA-21560: argument 3 is null, invalid, or out of range error occurs. I'm also wondering why and what the other error means saying LOBs are open during transaction commit time. The data is coming from an xml file that is in the following format.
- <NAME>
<FIL_NM>TEST.PDF</FIL_NM>
<VER>2</VER>
<DETAILS>xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxyyyyyyyyyyyyyyyyyyzzzzzzzzzmmmmmmsusssuitttttretc</DETAILS>
</REPORT>
<NAME/>
So what this procedure is doing is opening the pdf and loading the data into the BLOB. I just can't understand what is causing those errors.

DBMS_LOB.WRITEAPPEND - HELP!

Why is my code failing? All I am doing is reading text from an external file (UTL_FILE package) and appending it onto an NCLOB variable, but the WRITEAPPEND to the NCLOB variable is failiing. I know the WRITEAPPEND is failinb because I instrumented the code with DBMS_OUTPUT statement. I get the following error message with the following code:
DECLARE

You can use the returning clause to store the generated sequence value that was inserted into id into a variable, then reference that variable in the rest of your code, as demonstrated below.

1) select 하는 예제
- pro*c 2.2에서 compile하는 경우는 package로 DBMS_LOB package 호출을
encapsulate 해서 사용해야 하고, proc 8.0 이상에서 compile하는 경우
DBMS_LOB package를 직접 호출하는 것이 가능하다.

Nobody can solve this DBMS_LOB problem:

I want to upload text file to ftp server but when i open file mcx.txt which is in e:\middle-east\ssm dmbs_lob.fileopen() function give error. edit e:\middle-east\ssm\mcx.txt; command also open this text file properly.
ORA-22285: non-existent directory or file for FILEOPEN operation
ORA-06512: at "SYS.DBMS_LOB", line 523
ORA-06512: at "SCOTT.FTP", line 128
ORA-06512: at "SCOTT.FTP", line 355
ORA-06512: at line 7
FUNCTION get_local_ascii_data (p_dir IN VARCHAR2,
p_file IN VARCHAR2)
RETURN CLOB IS
l_bfile BFILE;
l_data CLOB;
BEGIN
DBMS_LOB.createtemporary (lob_loc => l_data,
cache => TRUE,
dur => DBMS_LOB.call);
l_bfile := BFILENAME(p_dir, p_file);
DBMS_LOB.fileopen(l_bfile, DBMS_LOB.file_readonly);
DBMS_LOB.loadfromfile(l_data, l_bfile, DBMS_LOB.getlength(l_bfile));
DBMS_LOB.fileclose(l_bfile);
RETURN l_data;
END;

Just for the sake of clarification ... What value are you specifying for p_dir variable?
It should be a directory object created in the database.
It can be created with a command like
CREATE OR REPLACE DIRECTORY BFILE_DIR AS 'e:\middle-east\ssm';
and the user who is going to call the function should have read access on this directory object which can be granted with a command like
grant read on directory BFILE_DIR to FUNCTIONCALLINGUSER;
I hope this helps with what you are trying
Best Regards
