Thanks in advance!Your question is unclear.
BLOB = large object storage for Binary data.
CSV = Character seperated values, representing character based data.
Download = terminology for transferring files or data from the internet to a local client computer.
So, questions...
Why are you storing character data in a binary datatype?
What do you mean by "download"?
and as an aside...
Why are you using such an outdated and unsupported version of Oracle? Get it upgraded.

How to extract information in cells of a mult-column list box?

I have multi column list box. At run time this listbox allow me to select entire row (this is fine), how to extract the data from each cell along the selected row? It seems to me that the Multi column Listbox (MCL) is merely a 1D array (I guess index of this 1D array corresponds to row index of the MCL and value of the element corresponds to column index of MCL.)

To extract cell values of the selected row, you can create a property node for the MCL. From this property node, choose "Item Names". This is a 2D array containing all cell values. Index this array with the MCL terminal. Note that you must choose the scalar data type for the MCL. To choose the scalar data type, right click on the MCL and go to "Selection Mode"->"Data Type"->"Scalar".
See attachment written with LabVIEW 6.
I hope it will help you.

How to generate a .pdf output for a BLOB column?

Hi friends,
(Forms 6i)
I have a .pdf into a blob column and I want to show that .pdf as my report output...
Example-> The report only have this query:
select myblob_ column
from mytable
the column in database has the .pdf ... but when I execute the report, it only appears some information when I put the item to show as Text... But obviously it's not the ofriginal pdf...
If I try to put as OLE2 doesn't appear either anything and if I try to put it as an Image, it appears a message error.
Any ideas?
Thanks.

How can I open different binary files from BLOB column ?

If we store some type of binary file (XLS, DOC, PDF, EML and so on, not only pictures) in BLOB column how can I show the different contents? We use designer and forms 9i with PL/SQL.
How can I copy the files from BLOB to file in a directory or how can I pass BLOB's content to the proper application directly to open it?

The mime type is just a string as explained above (e.g. application/pdf...). There are lot of samples here and on metalink.
E.g. add a column mime_type varchar(30) to your blob table. Create a procedure similar to the following:
PROCEDURE getblob
(P_FILE IN VARCHAR2
IS
vblob blob;
vmime_type myblobs.mime_type%type;
length number;
begin
     select document, mime_type into vblob,vmime_type from myblobs where docname = p_file;
     length := dbms_lob.getlength(vblob);
     if length = 0 or vblob is null then
     htp.p('Document not available yet.');
     else
     owa_util.mime_header(vmime_type);
     htp.p('Content-Length: ' || dbms_lob.getlength(vblob));
     owa_util.http_header_close;
     wpg_docload.download_file(vblob);
     end if;
exception
     when others then
     htp.p(sqlerrm);
END;
Create a DAD on your application server (refer to documentation on how to create a DAD).
Display the blob from forms (e.g. on a when-button-pressed trigger):
web.show_document('http://myserver:port/DAD/getblob?p_file=myfilename','_blank');
For storing blobs in a directory on your db server take a look at the dbms_lob package.
For storing blobs in a directory on your app server take a look at WebUtil available on OTN.

How to know exact size of table with blob column

I have a table with one BLOB column. I ran this query.
select bytes/1024/1024 from user_segments where segment_name='GMSSP_REQUEST_TEMP_FILES'
(user_segments is a view)
it gave me 0.125
It means size of table is 0.125. I have uploaded 3 files to this table. Each of them is of 5 mb. After that I check size of table. but result was same. i.e 0.125.
Can any body tell me how to know exact amount of space consumed by files. I am expecting following result
size should be (5+5+5+0.125)MB
Any help is appreciated.
Thanks.

How can I insert a image into a BLOB column in a table?

I am using forms6i against a 10gR2 database and I have one table with a BLOB column and I try to insert a image into this column. I get ORA-01461 error.
The curious case is that in another table with a BLOB column it works very fine.
What happens with the first table? How can I avoid the error?
Thanks in advance.

How to get the File-Type from a BLOB-Column

Hi all,
I have the database table with the BLOB-Column. In this column are Word/Pdf/Excel/... files can be stored.
Now I want to open these Files from Webforms.
I can download the file from database to the client and then open the file with client_ole2.CREATE_OBJ('Word.Application');
But I can not be sure that the file is a Word-Document.
How can I know which application is saved in the BLOB-column?
Regards

Hi Francois,
thank you.
Unfortunatelly I do not know the interMedia functions. Can you send me an example with interMedia?
I am working with your solution with WEBUTIL_HOST.blocking.
But when I do not give the extension for the file, in that the BLOB will be temporary stored, I get to see the Windows "Select Program..." window. When I select Word or anything else then the file will be opened, but the locking does not working.
Any ideas?
Regards

When inserting into less than 4000 bytes, it is inserting without any issues. If i am inserting more than that, it is throwing
error like this ORA-01460: unimplemented or unreasonable conversion requested.
Can anybody guide me how to do this or link.
Thanks in advance.

Before, I have not worked with BLOB column, so I don't know much about its using. Currently, I am using direct

with this BLOB column. I am able to insert into table, if the inserted file is less than 4000 bytes. If it is more than that,
I am getting that problem.

Import From Folder: How to Extract the File Name in a Custom Column.

Hello All
Here´s what we´re trying to do:
We have a folder with csv files named like this:
Sales_2013-02-05.csv
Sales_2013-02-04.csv
Sales_2013-02-03.csv
Sales_2013-02-02.csv
Sales_2013-02-01.csv
And in the csv files there are the sales columns but not the date column.
So we want to extract the date from the file name.
I´ve tried entering = Source[Name] in a custom column, but it adds a "LIST" link, and on a click on expand, it adds ALL file names from the folder in each row, instead of just the needed one.
If we could get the proper file name in each row (from where they got extracted), we could split the column and get the date from there. But I don´t know how put the filename there properly.
Can you help?

This isn't entirely straightforward, but it's definitely possible. What you need to do is to apply all of your transforms to each individual file instead of the combined files. I do that as follows:
1) Use Folder.Files as generated by the GUI to look at the list of my files.
2) Pick one file and do all the transformations to it that I want to apply to all of the files. Sometimes, this just amounts to letting the autodetection figure out the column names and types.
3) Go into the advanced editor and edit my code so that the transformations from step 2 are applied to all files. This involves creating a new function and then applying that function to the content in each row.
4) Expand the tables created in step 3.
As an example, I have some files with names that match the ones you suggested. After steps 1 + 2, my query looks like the following:
let
    Source = Folder.Files("d:\testdata\files"),
    #"d:\testdata\files\_Sales_2013-02-01 csv" = Source{[#"Folder Path"="d:\testdata\files\",Name="Sales_2013-02-01.csv"]}[Content],
    #"Imported CSV" = Csv.Document(#"d:\testdata\files\_Sales_2013-02-01 csv",null,",",null,1252),
    #"First Row as Header" = Table.PromoteHeaders(#"Imported CSV"),
    #"Changed Type" = Table.TransformColumnTypes(#"First Row as Header",{{"One", Int64.Type}, {"Two", type text}, {"Three", type text}})
in
    #"Changed Type"
For step 3, I need to take steps 3-5 of my query and convert them into a function. As a check, I can apply that function to the same file that I chose in step 2. The result looks like this:
let
    Source = Folder.Files("d:\testdata\files"),
    Loader = (file) =>
        let
            #"Imported CSV" = Csv.Document(file,null,",",null,1252),
            #"First Row as Header" = Table.PromoteHeaders(#"Imported CSV"),
            #"Changed Type" = Table.TransformColumnTypes(#"First Row as Header",{{"One", Int64.Type}, {"Two", type text}, {"Three", type text}})
        in
            #"Changed Type",
    #"d:\testdata\files\_Sales_2013-02-01 csv" = Source{[#"Folder Path"="d:\testdata\files\",Name="Sales_2013-02-01.csv"]}[Content],
    Loaded = Loader(#"d:\testdata\files\_Sales_2013-02-01 csv")
in
    Loaded
Now I apply the same function to all of the rows, transforming the existing "Content" column into a new value:
let
    Source = Folder.Files("d:\testdata\files"),
    Loader = (file) =>
        let
            #"Imported CSV" = Csv.Document(file,null,",",null,1252),
            #"First Row as Header" = Table.PromoteHeaders(#"Imported CSV"),
            #"Changed Type" = Table.TransformColumnTypes(#"First Row as Header",{{"One", Int64.Type}, {"Two", type text}, {"Three", type text}})
        in
            #"Changed Type",
    Transformed = Table.TransformColumns(Source, {"Content", Loader})
in
    Transformed
Finally, I need to expand out the columns in the table, which I can do by clicking on the expand icon next to the Content column header. The resulting query looks like this:
let
    Source = Folder.Files("d:\testdata\files"),
    Loader = (file) =>
        let
            #"Imported CSV" = Csv.Document(file,null,",",null,1252),
            #"First Row as Header" = Table.PromoteHeaders(#"Imported CSV"),
            #"Changed Type" = Table.TransformColumnTypes(#"First Row as Header",{{"One", Int64.Type}, {"Two", type text}, {"Three", type text}})
        in
            #"Changed Type",
    Transformed = Table.TransformColumns(Source, {"Content", Loader}),
    #"Expand Content" = Table.ExpandTableColumn(Transformed, "Content", {"One", "Two", "Three"}, {"Content.One", "Content.Two", "Content.Three"})
in
    #"Expand Content"
From here, you should be able to get to what you want.

How to extract a string value from a varchar column

Please suggest.

make a new temporary table table wirth columns as the same name as TAGS in your XML.
extract the XML in a temporary variable.
pass it to the below proc with the table name created in step1 , it will populate the temporary table with the XML data.

How to view PDF files strored in a BLOB column

Hi all,
I want to display a PDF file, stored in a BLOB column, in a form or through a JavaBean.
But the problem is more complicated then that. I do not want to retrieve the PDF file in the application server that show it through a browser.
Actually, I do not want users to get the entire file, I just want them to see it or print it.
I want, in fact, to display a "stream" of bytes through Oracle Forms. Not a file.
This one, sounded to be a good solution, but actually not. When the file was too big (multiple pages), the application was blocked until the entire file was loaded. And when you try to print it, it wasn't printed right. The advantage of this solution is that it is open-source so we can add methods to connect to the DB, retrieve the content of the BLOB column and displays it without downloading the file.
Here is a good solution. Really good, files are loaded quickly, the rendering is really good and the file is printed perfectly (as it was printed from Adobe Acrobat). The disadvantage of this solution is that it is not open-source and is really expansive.
As you can see, both solutions uses PJC.
So any help, any idea to solve my problem will be highly appreciated.
Thanks to all of you,
Amine
PS : I am using F&R 11gR2

Not entirely. At least we came to the conclusion it doesn't make (much) sense to block the save option of PDFs if you want to allow printing them
Anyway; there is of course another possibilty: you could always write your own java bean PDF reader; there are plenty of java PDF libraries available:
Open Source PDF Libraries in Java
The easiest way would be to choose one which can open a PDF from a URL and render it; I would retrieve the image via mod_plsql using WPG_DOCLOAD and simply use the PDF library to render the PDF. No tempfiles anyway, and if you don't implement it there is also no save button.
cheers

How to batch upload PDF files into database BLOB

Hello.
I have a requirement to batch upload PDF files into BLOB column of an Oracle 8.1.7 table from Forms 6i Web. The content of the blob column (ie. the PDF content) MUST be displayable from all client software (eg. Oracle Web forms, HTML forms, etc.)
Our environment is
Middle-tier is 9iAS on Windows/2000
Database is Oracle 8.1.7.0.0 on VMS
Oracle Web Forms 6i Patch 10
Basically my Oracle web form program will display a list of PDF files to upload and then the user can click on the <Upload> button to do the batch upload. I have experimented the following approaches but with no luck.
1. READ_IMAGE_FILE forms built-in = does NOT work because it cannot read PDF file. I got error FRM-47100: Cannot read image file
2. OCX and OLE form item = cannot use this because it does NOT work on the Web. I got error FRM-41344 OLE object not defined
3. I cannot use DBMS_LOB to do the load because the PDF files are not in the database machine.
4. Metalink Note 1682771.1 (How to upload binary documents back to database blob column from forms). When I used this, I got ORA-6502 during the hextoraw conversion. In using this solution, I have downloaded a bin2hex.exe from the Google site. I've noticed that when I looked at the converted HEX file, each line has the character : (colon) at the beginning of each line. I know the PDF file has been converted correctly to HEX format because when I convert the HEX file back to BIN format using hex2bin.exe, I'm able to display the converted bin file in Acrobat Reader. When I removed the : (colon) in the HEX file, I did NOT get the ORA-6502 error but I CANNOT display the file in Acrobat Reader. It gives an error "corrupted file".
5. upload facility in PL/SQL Web toolkit - I tried to automatically submit the html form (with htp.p) but it does NOT load the contents of the file. I called the URL from Oracle forms using web.show_document. There seems to be issues with Oracle Web forms (JInitiator) and HTML (+ htp.p).
The other options I can think of at this point are:
1. Use SQL*Loader to do the batch upload via SQL*Net connection and use HOST() built-in from Oracle Webforms to execute SQL*Loader from the 9iAS.
2. Write a Visual Basic program that reads a binary file and output the contents of the file into a byte array. Then build a DLL that can be called from Oracle webforms 6i via ORA_FFI. I don't prefer this because it means the solution will only work for Windows.
3. Write a JSP program that streams the PDF file and insert the contents of the PDF file into blob column via JDBC. Call JSP from forms using web.show_document. With this I have to do another connection to the database when I load the file.
4. Maybe I can use dbms_lob by using network file system (NFS) between the application server and VMS. But this will be network resource hungry as far as I know because the network connection has to be kept open.
Please advise. Thank you.
Regards,
Armando

I have downloaded a bin2hex.exe from the Google site.
... each line has the character : (colon) at the
beginning of each line. I'm afraid it isn't a correct utility. I hope you'll find the source code of a correct one at metalink forum:
Doc ID: 368771.996
Type: Forum
Subject: Uploading Binary Files: bin2hex and hex2bin do not reproduce the same file
There is some links to metalink notes and some example about working with BLOB at http://www.tigralen.spb.ru/oracle/blob/index.htm. Maybe it helps. Sorry for my English. If there is any problem with code provided there, let me know by e-mail.

How can we find size of a table having blob columns

I have a problem in which i need to get the size of table that ishaving BLOB column in it.
How to find the size?
for ex: i am having a table DocBlob which is having a BLOB column DocObject. How to get the size of DocBlob table?
Also how one can see the data of the BLOB column. In toad or Pl/Sql dev tool, we can not see anything. here we use to store the images in it. how we can verify that what image or data is stored in these columns??
thanks..

Tables are segments. LOB Segments are segments.
SELECT blocks or bytes FROM user_segments
You can also use dbms_lob.getlength to retrieve the length of a LOB.
