Getting blobs from databases

Hi!
Im trying to get a blob from a database and write it to a file, but I just can't get the Blob value, I just recieve the adress. I've tried InputStream and getBytes but none of them does what I want. getBytes where closest but because it requires two inparameters (long pos, int length) and blob.length gives an long i can't figure out how many bytes to get. Anyone got any sugestions?

Agrawal.
I've read through both those pages (even thou i've already managed to make the connection to mysql) and I still can't work around my problem. the method getBytes(), requires two parameters, one that tells it where to start reading and one telling it how long it should read. If I leave one out it will inevitable lead to problems. So I still need to figure out a way to get the length of the blob in a int to make this work. but since the blob.length() method returns a long wich I can't convert I'm stuck!

As this is prototyping, i have downloaded Free As2 client and trying to send files to that client from PI.

Hi Dinesh,
make sure to also configure a report channel (refer to the sample chapter in the SEEBURGER AS2 documentation) in order to receive AS2 MDNs for your sent message. Additionally report channels are needed if the SEEBURGER specific TransmissionReports are requested.
Hope that helps

How to show in a report a pdf blob from database

Hi all
We are working on report 6i and report 10. We have a report wich needs to show a blob field from database that storages a pdf (type application/pdf). OLE2 is deprecated. The pdf blob field must be displayed in a preview and must be printed. In local, it works. When it works on a browser, the pdf blob field is missing. If we load the field into a pdf file, the field is not visible in the browser.
Do not get it to work. How I can implement? Could you give us any example for this?

In local, it works. What do you mean by that exactly? You see the pdf in Reports Builder?
If you just want to show the pdf in a browser (not embedded in a report) it is easy to use mod_plsql. You can have a simple db procedure like this to show any kind of blob:
procedure show_webdoc(io_blob    in out nocopy blob
                     ,i_mimetype in varchar2
                     ,i_filename in varchar2)
is
begin
   if dbms_lob.getlength(io_blob) >0 then
      owa_util.mime_header(nvl(i_mimetype,'application/octet'),false);
      htp.p('Content-length: ' || dbms_lob.getlength(io_blob));
      htp.p('Content-Disposition: inline; filename="'||i_filename|| '"');
      owa_util.http_header_close;
      wpg_docload.download_file(io_blob);
   end if;
end show_webdoc;

Forms 9i: How get image from database?

Hi!
I want to get a image (GIF,JPG, TIFF, etc.) that is stored in database table (as blob) in Image_Item (No Database Block) by Trigger (PL/SQL) way.
In a Block that is database=yes It's OK, the Query do this in automatic.
I know that "select column into block_item from db_table" is not possible.
Thanks!

I have a multi-row block for entry data, so was thinking in a image item (No Database) in the same block for show a GIF when the user entry one code; then I will not need any thing more for show the correct GIF in each row when the user scroll them.
The other way, if I create one block-image_item for each row that is displaying; then I need create a Procedure por Syncronize the data row with the GIF; this mean a lot re-quering when the user is scrolling the rows. This is the reason I searching one Instruccion equivalent to read_image_file (but in place Operating System from database) or dbms_lob.read( ... ) but the target must be a block image item.
Thanks.

Also separate that database code from interface display code.
You should never access the database on the EDT.
See [Doing Swing Right|http://bytes.com/topic/java/insights/853297-doing-swing-right] for more details.
Yes! By the time you are working with Swing and JDBC you should already know how to structure code. If not, then you are not ready for these topics and you've jumped the gun.

Getting response from Database by sending in parameters

Hi,
I am providing parameter which supplies string values to query the database using adapter. I can see the invoke activity sending the string value to the database, but respnse message does not contain anthing.
Can someone please tell me how to retrieve records from database by suplying parmeter value?
Thank You
Anil

hi Anil,
use a simple stored procedure or pl/sql function and specify the input and output parameters. We can send any no of parameters to a function and a function can able to return a value. so you can achieve your requirement using pl/sql functions. Learn about that more.
when you will define ParterLink (using DBAdapter browing databse to select your function ), you shud be able to view one OUT parameter with datatype what you have mentioned earlier in pl/sql function. When you define Invoke for that Parterlink, you should get Invoke Output variable with output variable (having name of that function.)
If you cannot browse the function in your DB Adapter, just make sure that the user you have defined in DB Adapter has enough privileges to access that function.

Getting record from database

hai gys
i have database with date.i want to get the data from database between two dates.
i have not entered entered data for some dates.
now i want query , which will also show the dates (which are left ) with null data in the database
pl. give me query

This is some sample program and still can be tuned for performance.
DECLARE
l_start_date DATE := To_Date('01-JAN-2007','DD-MON-YYYY');
l_end_date DATE := To_Date('31-JAN-2007','DD-MON-YYYY');
l_count NUMBER;
l_cur_date DATE;
l_exist NUMBER;
BEGIN
l_count := l_end_date - l_start_date;
FOR i IN 0..l_count
LOOP
l_cur_date := l_start_date + i;
l_exist := 0;
SELECT Count(1)
INTO l_exist
FROM table_name
WHERE date_column = l_cur_date
AND ROWNUM < 2;
-- Use trunc on dates if required.
IF l_exist = 0 THEN
Dbms_Output.put_line(l_cur_date);

Dowload blobs from Database

I know this is not the best way to store files but I have inherited an old php script which I am converting to CF because php is useless.
Now i have a script to do this in php but can this be achived with CF? It is just a quick fix until I have time to rework the CMS
<?php
if(isset($_GET['id']))
// if id is set then get the file with the id from database
$id    = $_GET['id'];
$query = "SELECT name, type, size, content " .
         "FROM upload WHERE id = '$id'";
$result = mysql_query($query) or die('Error, query failed');
list($name, $type, $size, $content) =                                  mysql_fetch_array($result);
header("Content-length: $size");
header("Content-type: $type");
header("Content-Disposition: attachment; filename=$name");
echo $content;
i
exit;
?>

My php experience is NILL, but applying basic coding experience I believe your CFML will be close to this.
<cfif structKeyExists(url,"id")>
<cfquery datasource="..." name="result">
    SELECT name,type,size,content
    FROM upload
    WHERE id = <cfqueryparam value="#url.id#" cfsqltype="cf_sql_integer">
</cfquery>
<cfheader name="Content-Disposition: atachment; filename=#result.name#">
<cfcontent type="#result.type#" reset="yes">
#result.content#
</cfif>
If any of this content can be binary, then you may also need to use one or more of the toBinary() toBase64(), isBinary(), binaryDecode() or other relevant functions.

Getting Image from database in crystal report

Hi Experts,
I have a user UDF which has Image datatype. I store all the image in C:\Program Files\SAP\SAP Business One\Bitmaps\ folder.Now i have to show this image in my crystal report. When i tried to pick this image from database it gives me only the name of image with extension like abc.jpg . How could i achive this in crystal report.
Thanks and Regards

Hi Om
As you have the location of the image, you can insert it as an OLE object onto the report.
Click on Insert -> OLE Object -> specify the path of the image.
For more information, please refer to Crystal Reports help.

I have my java code for converting the blob to string as below.
String input = (String)getVariableData("*EnhancedBLOBdata*");
Base64Decoder baseDecoder= new Base64Decoder();
try {
byte[] decodedBytes = input.getBytes();
String decoded = new String(decodedBytes);
//String decoded = Base64Decoder.decode(input);
setVariableData("DecodedString", decoded);
catch(Exception ex)
ex.printStackTrace();
The data type of EnhancedBLOBdata is base64Binary.. I also checked with 'string' . Even then i dint get the proper decoded form.
Can anyone help me in using the variable SOURCE_XML coming under the RetrieveRecordForInstanceIdOutputCollection, directly in the line,
String input = (String)getVariableData("*Invoke_Output_Variable....<some format>*");
so that there is no need of assigning to some other variable.. Bcz while assignig i am not sure, the assigned variable contains data in blob format.
Kindly help me in this regard.
Thanks,

I have written java embedding code for converting this BLOB to xml as below
String input = (String)getVariableData("binaryXML");
try
/* *** INITIALLY I TRIED LIKE THIS*** */
//byte[] decodedBytes = Base64Decoder.decode(input.getBytes());
//String decoded = new String(decodedBytes);
//setVariableData("decodedString",decoded);
/* *** MY NEW CODE *** /
String decoded = Base64Decoder.decode(input);
setVariableData("decodedString",decoded);
catch(Exception ex)
ex.printStackTrace();
My Doubt
When I try to write this 'decodedString' to a .txt file, I couldnt find any output there.
<assign name="Assign3">

Can not get data from database

hi all,
    there is a problem , when i write like below :
SELECT * FROM bsis INTO CORRESPONDING FIELDS OF TABLE it_temp
          WHERE bukrs = p_bukrs
            AND hkont = p_hkont.
p_bukrs , p_hkont are all on the selection screen , and p_bukrs = 1200 another is eq blank. i can not find any data , but with the same condition i can find some data in database , when i debeg i found that p_hkont is initial.
    when i write like this :
SELECT * FROM bsis INTO CORRESPONDING FIELDS OF TABLE it_temp
          WHERE bukrs = p_bukrs .
this time i can find the data like the database.
    so , does someone know where the problem is , why i can not get data ?
kind regards
kevin

hi,
if u r using bukrs and hkont as parameters in selection screen then
SELECT * FROM bsis INTO CORRESPONDING FIELDS OF TABLE it_temp
WHERE bukrs = p_bukrs
AND hkont = p_hkont.
this will work.
if u r using then as select-option then the above does n't work.
bcoz select-options work as internal table bcoz of that u have use the query like this
SELECT * FROM bsis INTO CORRESPONDING FIELDS OF TABLE it_temp
WHERE bukrs IN p_bukrs
AND hkont IN p_hkont.
