Calculating CRC of file in BLOB field

i want to calculate a crc of a file in a BLOB field. Is this possible in PL/SQL (possible via Java stored procedures?).
Does anyone has some experience with this?
thanks

Hi Gert,
I think SYS.dbms_obfuscation_toolkit.MD5 is the right function ?,
but did it not use.

Downloading a file from Database [Blob field]

I am trying to write an application which can upload and download files [Excel, Word etc.] to/from an Oracle 9i database Blob field. I am using Java/JSP for the same.
The upload part works just fine. However, when I try to download the file that I uploaded, I get an error.
A dialog box comes up asking me to Open/Save the file. However, when I try to save it, it says
�Internet Explorer cannot download �..tion=download&planId= testplan from localhost
Internet Explorer was not able to open this Internet Site. The requested site is either unavailable or cannot be found. Please try again later.�
I am using IE 6.0. I tested the same with Firefox browser and was able to download the file.
Can anyone help?
Code:
Following is the code I am using for the same.
/* Code to retrieve from Blob field */
String sqlString = "SELECT PLAN_DOCUMENT_NAME,PLAN_DOCUMENT FROM BRS_PLAN_DESCRIPTION WHERE PLAN_ID = ?";
ps = con.prepareStatement(sqlString);
ps.setString (1,planId);
rs = ps.executeQuery();
while (rs.next()) {
     fileBytes = rs.getBytes("PLAN_DOCUMENT");
     fileName = rs.getString("PLAN_DOCUMENT_NAME");

Hi,
is this problem solved for you, I am also writing the java code to store different files in blob fields in database(db2udb) and allow users to open them through jsp pages. Upload seems to be working fine.....My big problem is only excel files are opened properly in both IE and Firefox. Word files, image files are not getting opened. Any suggestion as what I could be doing wrong....my jsp is kind of similar to the above one...

BLOB fields again...

Hello,
I'm developing an application which has a database table with blob fields. I've had many problems recently with this type of field, the most undesired being that LOV fields doesn't work in pages with BLOB fields.
As a workaround, I've done a second page just to upload the files to the two blob fields. It worked, but now I needed to handle errors with different kind of files and their mime-types. I was happy to see that JHeadstart provided three auxiliary fields to store the filename, size and mime-type. It worked too, it saved all that information correctly, but:
1. When "downloading" the file, apparently the mime-type is not set.
2. Just after the file is uploaded, I can see in the main table that the attributes were saved correctly, but as soon as I close the browser and open a new session, I have errors. I have two blob columns; in the first, it doesn't shows the filename, but the file size, in the second blob column, it doesn't shows the file name, but the blob mime-type!
Does anybody has any similiar problem?
Thanks,
Eduardo

Hello Peter,
Thanks for the confirmation that the BLOB / LOV issue is a bug.
About my another problem with HTTP headers while downloading files from blob fields, you are right, I need to be more specific. In my first try, this "second page" just to upload the files was a simple UIX page, not generated by JHeadstart. I saw this could be a little difficult to handle, so I discarded it.
Now, I created a second VO with the two blob fields and all other attributes read-only, and put it as a group in JHeadstart configuration file to generate the page automatically. I __disabled all multi-row operations__ so the blob fields are rendered in the main table as hyperlinks to be downloaded with their respective filenames set, as it was saved in the database field in the upload.
But in my tests, if I save other files than images, the browser doesn't open it correctly. So I opened the UIX JHeadstart generated page, where I see something like this:
<link destination="DownloadFile.do?pageTimeStamp=ignore&model=TsacContratoUIModel&binding=TsacContratoDocumentoContrato&rowKeyStr=${uix.current.rowKeyStr}&attachment=${TsacContratoDocumentoContratoTamarq}" text="${ui:cond(uix.current.TsacContratoDocumentoContratoTamarq!=null,uix.current.TsacContratoDocumentoContratoTamarq,'DocumentoContrato')}" rendered="${uix.current.TsacContratoDocumentoContrato!=null}"/>
Clearly I can see two things:
1. attachment=${TsacContratoDocumentoContratoTamarq}. I put uix.current inside, as we are in a table, and it worked fine after that.
2. The hyperlink doesn't have the mimeType parameter set, but the respective DownloadFile.do class uses it to set the correct mimeType header. I put it by hand: &mimeType=${uix.current.TsacContratoImagensViewDocumentoContratoMimetype}"
I verified that all the three attributes used to save file information are correct and exists in the VO, in the entity object and in the table, and I've also tested it in the Application Module and also, they save all the information correctly, so I don't think the problem is here, but in the page generation.
Thanks for your help. JHeadstart is a great and very interesting project despite some minor bugs that still exists.

File to BLOB

Hi everybody.
I'm newbie with Java. How to put file to BLOB field?

Error displaying a jpg file loaded into a table with blob field

This may not be the correct forum for this question, but if it isn't could someone direct me to the correct one.
I have created a table with a blob field in which I have loaded a jpg image. This appeared to work correctly, but when I try to display the image in internet explorer it comes back and tells me that it doesn't recognize the file type. Enclosed is the table create, load, and display pl/sql code. Can anyone tell me what I am doing wrong. Thanks. For the mime/header I used owa_util.mime_header('images/jpg') because my image is a jpg file.
The database is 10g

The url I enter is: http://webdev:7777/tisinfo/tis.tiss0011.Display_Image?p_id=1

Just a little more information. When I enter owa_util.mime_header('image/jpeg') I can't display the file. It just shows up with a red x for the file.
When I enter owa_util.mime_header('image/jpg') it displays the file, but in the format
¿¿¿¿JFIF¿¿-Intel(R) JPEG Library, version [2.0.16.48]¿¿C
This is the way I would expect it to look if I opened it with Notepad, or an application that doesn't recognize jpg files. Can anyone tell me what I am doing wrong?? Thanks.

How to upload size 4k file to oracle BLOB field

hi all, i'm using Oracle 9i, Orcale JDBC thin Driver and ibm websphere to develop a java application.i have used java EJB/CMP to insert images into BLOB field in oracle.
i used byte[] mapping to BLOB.i did it successfully.
however, i'm facing another problem. it is that
when i insert files larger than 4k, there is exception error. it said that the inserted value is too large.
is that the problem of orcale JDBC?
is that any solution to solve this restriction?
it is very urgent, pls help!
thx a lot

Hi Lee
Thanks for ur valuable suggestions. Please give me
more idea i would really thank to u !Which part is giving you troubles?
Oh - and change my suggestion to use setBinaryStream to a suggestion to use setAsciiStream, as I missed the part where you said "text file".
>
Can anybody tell me anyother way how to solv thid
problem
Depending on the size of the text file you could just read the file so you have the contents as a String and use setString (also in the PreparedStatement interface).

Loading class file stored in BLOB field

- I am able to store and retrieve Java files and XML files in and from a BLOB field, but when I store a class file and try and load it using Class Loader, it us unable to load the class. The size of the class file increases by 1 byte when I retrieve it from the database. Is this some security feature by the JVM? Is it not possible to store, retrieve and load a class file from a database table?
Thanks

Hi,
First, I would suggest you use fiddler (http://www.telerik.com/fiddler) to compare these two different client requests, second, please try to use Azure Storage Explorer (http://azurestorageexplorer.codeplex.com/) to do
this instead of the Azure Web Storage Explorer.

Storing a file in a BLOB field in the database through forms

Hi, I want to have a form that lets the user choose a file he has on his client side and load this file into a BLOB field in the database.
I know how to use "GET_FILE_NAME" to get the file, the second part is what I'm having problems with. Do I use an OLE object? How do I initailize it? Or what is the best way to go? Thanks.

How to Convert the content in BLOB field into a PDF file...

You can't convert binary data into character based data.
So very likely this is your problem.

Error while trying to store PDF in Oracle's BLOB field

Hi folks!
I'm having problems while trying to store PDF file in a BLOB field of an Oracle table
This is the message code:
Exception in thread "main" java.sql.SQLException: Data size bigger than max size for this type: 169894

This is the piece of code i'm using:
Assuming conn = conection to Oracle 10g Database ( it's working )
String miProcedimientoAlmacenado = "{ call package_name.update_client(?,?, ?) }";
CallableStatement miComando = conn.prepareCall(miProcedimientoAlmacenado);
miComando.setString(1,miClienteID ); //first parameter : IN
               //second parameter : IN
File miPDF = new File(pathPDF + "//" + miClienteID + ".pdf");
byte[] bodyIn = readFully(miPDF); //readFully procedure is shown below
miComando.setBytes(2, bodyIn); //THIS IS THE LINE WHERE THE ERROR IS PRODUCED
          //3rd parameter: OUT
miComando.registerOutParameter(3, java.sql.Types.VARCHAR);
miComando.execute();
private static byte[] readFully(File miPDF) throws FileNotFoundException, IOException {
FileInputStream fis = new FileInputStream(miPDF);
byte[] tmp = new byte[1024];
byte[] data = null;
int sz, len = 0;
while ((sz = fis.read(tmp)) != -1) {
if (data == null) {
len = sz;
data = tmp;
} else {
byte[] narr;
int nlen;
nlen = len + sz;
narr = new byte[nlen];
System.arraycopy(data, 0, narr, 0, len);
System.arraycopy(tmp, 0, narr, len, sz);
data = narr;
len = nlen;
if (len != data.length) {
byte[] narr = new byte[len];
System.arraycopy(data, 0, narr, 0, len);
data = narr;
return data;
}//fin readFully
This approach indicates that the PDF file is converted into an array of bytes, then is stored as binary in the BLOB field.
Thanx in advance, and looking forward for your comments.

You will probably need to use the setBinaryStream() method instead of setBytes().

Retrieve XMLP documents directly from BLOB fields in E1; Tools Release 8.97

Hi,
I want to be able to retrieve XML Publisher reports (PDF, RTF, HTML) directly from the database BLOB fields in EnterpriseOne. Instead of making users manually save each report to get a soft-copy of the report, I wanted to be able to retrieve the reports from a BLOB field, create a new external file for it, and open the file with the related editor (MS Word, Adobe, IE, etc.).
We are on Oracle 10g, and I was able to get a file populated with some BLOB data for a particular RTF file. However, when I try to open the file in MS Word, all I get is junk.
Does anyone know if JDE stores these documents differently into BLOB fields than standard?
Here is the code I used using PL/SQL...
DECLARE
xmlstr BLOB;
warn VARCHAR2(400);
v_file Utl_File.file_type;
line_buf RAW(32767);
maxbufsize BINARY_INTEGER := 32767;
amount BINARY_INTEGER;
offset BINARY_INTEGER;
dir varchar2(50) := 'XMLP_DIR';
filename varchar2(50) := 'JPARK_TEST.rtf';
bsize NUMBER;
BEGIN
v_file := utl_file.fopen(dir,filename,'wb',maxbufsize);
SELECT xorpdxpblb INTO xmlstr FROM sy812.F95631 WHERE xorpdorgud = '2115630440008e-SMNQTWZCFI-YEKRWCIOUA';

bsize := dbms_lob.getLength(xmlstr);
dbms_output.put_line(bsize);

offset := 1;
WHILE (offset<bsize) LOOP
DBMS_LOB.read(xmlstr,amount,offset,line_buf);
utl_file.put_raw(v_file,line_buf, TRUE);
offset := offset+amount;
--utl_file.fflush(v_file);
--Dbms_Output.put_line(offset);
END LOOP;
utl_file.fclose(v_file);
EXCEPTION
WHEN OTHERS THEN
UTL_FILE.FCLOSE_ALL;
DBMS_OUTPUT.PUT_LINE('WHEN OTHERS');
dbms_output.put_line(substr(sqlerrm,1,254));
END;

the database and blob fields are identical. In the 11i (eBusiness suite) we would store this information in fnd_lobs.

Oracle error ORA-01461when trying to insert into an ORACLE BLOB field

I am getting Oracle error ‘ORA-01461: can bind a LONG value only for insert into a LONG column' when trying to insert into an ORACLE BLOB field. The error occurs when trying to insert a large BLOB (JPG), but does not occur when inserting a small (<1K) picture BLOB.(JPG). Any ideas?
BTW, when using a SQL Server datasource using the same code.... everything works with no problems.
ORACLE version is 11.2.0.1
The ORACLE datasource is JDBC using Oracle's JDBC driver ojdbc6.jar v11.2.0.1 (I also have tried ojdbc5.jar v11.2.0.1; ojdbc5.jar v11.2.0.4; and ojdbc6.jar v11.2.0.4 with the same error result.)
Here is my code:

Can't you use "alter index <shema.spatial_index_name> rebuild ONLINE" ? Thanks. I could switch to "rebuild ONLINE" and see if that helps. Are there any potential adverse effects going forward, e.g. significantly longer rebuild than not using the ONLINE keyword, etc? Also wondering if spatial index operations (index type = DOMAIN) obey all the typical things you'd expect with "regular" indexes, e.g. B-TREE, etc.

Can we use BLOB fields (that store images) in Crystal Report ?

I'm developing with ASP.NET, VS.NET 2003.
Using Crystal Report for VS.NET
DataBase: Oracle 10g
I store a BLOB field in a table. This field store images, like jpg files.
The Stored Procedure that I use to fill the report is:
OPEN MyCursor FOR
SELECT MyId , MyImg
FROM MyTable
MyImg is BLOB field
However, when I try to use the stored procedure in Crystal Report at design mode, any field can be displayed and then drag and drop to the report, but MyImg is not possible.
There is an error message:
Details: ADO Error Code: 0x80004005
Source: Microsoft OLE DB Provider for Oracle
Description: Data type is not supported
I'm afraid that is not so easy for me to change DB connector drivers.
My question is:
- Is it possible to use BLOB fields in Cyrstal Reports?
- Or should I convert them previously to something, so they can be displayed in Crystal Report at desing mode ?
- If I should change DB connector drivers, which one should I use and from where should I download it and then install it in my Web Server?
Thank you very much!

Hi,
I dont know much at all about CR, but I do know Microsoft's OLEDB Provider for Oracle doesnt support Blob datatype.. http://support.microsoft.com/kb/q244661/
Oracle's OLEDB provider does though, you can get it as part of the ODAC download on OTN.
Hope that helps,
Greg

Problem with update of BLOB field in a table with compound primary key

Hi,
I've been developing an application in Application Express 3.1.2.00.02 that includes processing of BLOB data in one of the tables (ZPRAVA). Unfortunately, I've come across a strange behaviour when I tried to update value in a BLOB field for an existing record via a DML form process. Insert of a new record including the BLOB value is OK (the binary file uploads upon submiting the form without any problems). I haven't changed the DML process in any way. The form update process used to work perfectly before I'd included the BLOB field. Since than, I keep on getting this error when trying to update the BLOB field:
ORA-20505: Error in DML: p_rowid=3, p_alt_rowid=ID, p_rowid2=CZ000001, p_alt_rowid2=PR_ID. ORA-01008: not all variables bound
Unable to process row of table ZPRAVA.
OK
Some time ago, I've already created another application where I used similar form that operated on a BLOB field without problems. The only, but maybe very important, difference between both the cases is that the first sucessfull one is based on a table with a standard one-column primary key whereas the second (problematic one) uses a table with compound (composite) two-column PK (two varchar2 fields: ID, PR_ID).
In both cases, I've followed this tutorial: [http://www.oracle.com/technology/obe/apex/apex31nf/apex31blob.htm]).
Can anybody confirm my suspicion that Automatic Row Processing (DML) can be used for updating BLOB fields within tables with only single-column primary keys?
Thanks in advance.

Is there a chance that the bug will be included in the next patch?No, this fix will be in the next full version, 3.2.
