Inserting String data to BLOB column

Hi All
I want to insert String data into BLOB column using DBAdapter - through database procedure.
anybody can help?
Regards
Albin Issac

I have used utl_raw.cast_to_raw('this is only a test')).But for bigger string I get the error as "string literal too long" do we have any similar function for longer string.
Thanks,

Inserting Image into a BLOB column in Oracle9i

Hi,
I am unable to insert image into a BLOB column. I am using Forms 6i REL 2 and Oracle 9i. But I could do it on Oracle 8i with same Forms version.
Same thing is true for CLOB in 9i.
Would you please try with this code?
TABLE
Create table x
(Id number,
Name CLOB,
Pict BLOB);
WHEN-BUTTON-PRESSED trigge
declare
     x varchar2(265);
begin
     x := get_file_name;
     read_image_file (x, 'GIF', 'picture.pict');
end;
Take care,
Tarek

Forms 9i and Oracle 9i work fine together for this case.

Sample insert into table with BLOB column

This is my first opportunity to work with BLOB columns. I was wondering if anyone had some sample code that shows the loading of a blob column and inserted into the table with a blob column.
I have to produce a report (including crlf) and place it into a blob column. The user will download the report at a later time.
Any suggestions / code samples are greatly appreciated!!!!

You can enable string binding in TopLink.
login.useStringBinding(int size);
or you could enable binding in general,
login.bindAllParameters();

Display data from BLOB column.

Hi All,
I want to display data from blob datatype field, which contains HTML and GIF both files.
If I set it's property from file format IMAGE then i get data only gif.
if anybody have answer plz revert back...
awaiting...
Juned

Hi Juned
What I suggest is that you may have overlapping fields. One to show HTML and other to show GIF. You need to add one more column to your table in order identify if the BLOB is GIF or HTML.
In the Format Trigger of each of these two fields, inspect the value of flag column and hide one field if the datatype is not its type.
For instance, if flag field is 0 then hide Image field and show HTML field. If flag field is 1 then show Image field and hide HTML field.

Insert picture in a blob column and show in oracle forms

hi ,
please help me with this
I am trying to insert a picture into a blob column of a table and show that in oracle forms , but not able to do it .
I am using version 10g for both database and forms .
Please tell me how to insert a picture in a blob column that is stored in my 'c:\test' folder
and also how to show that in forms .

To populate the Image Item you have to use the Webutil Client_Read_Image_File() built-in.
here
http://www.oracle.com/webapps/online-help/forms/10g/state?navSetId=_&navId=3&vtTopicFile=f1_help/builtn_r/readimag.html&vtTopicId=
To add an Image Item to your block based on the table that contains the BLOB column, then give this Image Item the BLOB column name.
So that, all you have to do is to execute query on that block.

How to transfer data within blob column to server

Hi,
I have the following requirement where i have a table which has a blob column that holds the files that are attached to a page using front end. I need to fetch these files and import them to server. How do i go about in achieving this?
Any in\puts would be of great help.

Any in\puts would be of great help.Well, if the blob data is stored in columns on the database then it already resides on the server. If you need to save that data as files on the server then it's just a case of writing out the data to a file in the appropriate directory location.
Example code... (untested)...
As sys user:
CREATE OR REPLACE DIRECTORY MY_FILES AS 'c:\myfiles';
GRANT READ,WRITE ON DIRECTORY MY_FILES TO myuser;As myuser:
DECLARE
   -- Data Variables
   v_blob             BLOB;
   v_data_length      NUMBER;
   -- Loop Control Variables
   v_offset           NUMBER := 1;
   v_chunk   CONSTANT NUMBER := 32767; -- maximum chunk size
   -- UTL_FILE variables
   fh                 UTL_FILE.file_type;
BEGIN
   v_blob := ... populate the blob variable here
   v_data_length := DBMS_LOB.getlength (v_blob);
   -- Open the file
   fh := UTL_FILE.fopen ('MY_FILES', 'myfile.dat', 'wb', v_chunk);
   LOOP
      -- Exit when our file offset is bigger than our file
      EXIT WHEN v_offset > v_data_length;
      -- Write the output chunk by chunk
      UTL_FILE.put_raw (fh, DBMS_LOB.SUBSTR (v_blob, v_chunk, v_offset), TRUE);
      -- Increment the offset by the amount written
      v_offset := v_offset + v_chunk;
   END LOOP;
   -- Close the file

I have a question for you: Inserting Word document in BLOB column

Hey Experts,
I have found a good info and a sample on how to achieve this on
http://www.sys-con.com/java/source/5-6/code.cfm?Page=76.
declare
f_lob bfile;
b_lob blob;
begin
insert into sam_emp(empno,ename,resume)

return risumi into b_lob;
f_lob := bfilename( 'MY_FILES', 'MyResume.doc' );
dbms_lob.fileopen(f_lob, dbms_lob.file_readonly);
dbms_lob.loadfromfile

dbms_lob.fileclose(f_lob);

I have a jsp project and the users ( on the client side)must be
able to create a word document and send it to the server with an
uplaod servlet. With another servlet or jsp i want to process
this word document in BLOB column using JAVA. The sample above
uses PL/SQL to achieve this. Is there a way i can do this in my
servlet/jsp to do the same thing?
Any hints are welcome!

The option should be visible here: http://support.mozilla.com/en-US/kb/Printing%20a%20web%20page#w_print-window-settings
Print range section - Lets you specify which pages of the current web page are printed:
* Select '''All''' to print everything.
* Select '''Pages''' and enter the range of pages you want to print. For example, selecting "from 1 to 1" prints the first page only.
* Select '''Selection''' to print only the part the page you've highlighted.
Does it work for you?

String search in BLOB column

Hi All!
I have a table that contains text files in a BLOB column. I want to search for an 'input string' in all the text files in the column and replace it with 'replace string'. Is it possible to do this? And if so, how? Please suggest.
Thanking in advance.
Regards,
Deepika.

If the BLOB is smaller than 32767 in length, you can simply:
DECLARE
   p_blob   BLOB := UTL_RAW.cast_to_raw (RPAD ('X', 32767));
BEGIN
   p_blob :=
      UTL_RAW.cast_to_raw (REPLACE (UTL_RAW.cast_to_varchar2 (p_blob),
                                    'X',
                                    'Y'
END;

Inserting XML data into xmltype column

Oracle version: 10.1.0.5
OpenVms Alpha V8.3
1) Tried this and get the error shown below. Removed charset and placed a zero. Same error.
INSERT INTO xml_demo (xml_data) -- column of xmltype
VALUES
xmltype
bfilename('XML_DIR', 'MOL.XML'),
nls_charset_id('AL32UTF8')

ORA-06512: at line 1
2) This PL/SQL block works. However maximum raw size around 32K. The file can be around 100K. May be I can load it into a table of raw and somehow concatnate it to insert. Not sure whether this is possible but I am sure there must me a simple way of doing this.
Subset of the xml file is pasted below.
set serveroutput on size 1000000
DECLARE
file1 bfile;
v_xml XMLType;
len1 number(6);
v_rec1 raw(32000);

len1 := DBMS_LOB.getLength(file1);
v_rec1 := dbms_lob.substr(file1,len1,1);
v_xml := xmltype(UTL_RAW.CAST_TO_VARCHAR2(v_rec1));
INSERT INTO xml_demo (xml_data) VALUES (v_xml);
COMMIT;
DBMS_LOB.fileclose(file1);
exception
when others then
dbms_output.put_LINE (sqlerrm);
DBMS_LOB.fileclose(file1);

CMP to insert CLOB Data in Oracle

I have a CMP which tries to insert CLOB data into Oracle Database using XMLType column. We have tried multiple options
1. Inserting String data into XMLType column - if the value is more than 4000 chars, it gives an error
2. Inserting CLOB Data into XMLType column - Using the OracleCLob option in the deployment descriptor results in a SQLExcepotion Inconsistent datatype expected number found CLOB.
Can anybody provide a solution to this problem?
