RDB BLOB problem
Hi.
I have problem writing blob into RDB database table via JDBC driver. I use setBinarySteam() or setBytes() method in PreparedStatement.
If table has NOT NULL constraint on blob-field I'm trying to write JDBC driver throws exception:
java.sql.SQLException: in <rdbjdbcsrv:execute_into>
%RDB-E-INTEG_FAIL, violation of constraint NEW_BLOB_TABLE_NOT_NULL1 caused operation to fail
-RDB-F-ON_DB, on database DKB1:[PRO_DB.MB_DATABASE]MB.RDB;1

But if there is no constraint on this field everyyhing is ok. I'm using thin JDBC-driver.
I don't know what to do.
No, I'm not trying to set null value to this field.
For experiment I created two similar tables. One was created with NOT NULL constraint for blob column and the other one without.
And I execut identical insert-query on both of them. With first table query throws exception. And with second one everything is fine, query inserts correct data into this table.

Hi Joe,
I tried the two things you asked:
1. Setting the initial and max capacity of the Connection Pool to 1 does not make
any further difference, the reselt set is still sometimes empty.
2. If I use the code from the stand-alone application (thus if I get the connection
directly from the driver) than I get a good result: the retrieved result set is,
as far as I can see, always correctly filled.
In addition I tried to cast the Connection to WLConnection and then get the vendor
connection from it, and than to proceed with this connection further on, but this
did not make it any better.

Hi Joe,
thanks for your quick answer to my questions. I red your sugestionsand tried
them out but unfortunately it did not make me come any further in searchfor answer
to this odd problem. Setting the statement cache size to 0 (I've alreadytried
this before your response) did not make any difference at all. Refreshingthe
statement before reuse neighter.
I also tried to make the stand-alone application to go wrong. But nomatter whether
I reuse connection and/or statement or whether I instantiate the newones every
time, the execution of the statement always comes back with a validand filled
ResultSet.
Interesting thing to mention aboout executing the statement withinthe server
is that if I put it in a loop of let say 100 repeats, it succeeds orit fails
all 100 times. Next time i execute this bean method where the loopis situated
it will again succeed or fail all 100 times. It remains consequentwithin the
same loop/bean method. Even if I get the data source and the connectionevery
time again (100 times) it remains consequent. Thi is maybe interestingfinding
but it does not say anything to me. Perhaps you can make some conclusionsout
of it.
Best regards,
Almir.Hmmmmm.... Interesting. The only other thing I can suspect is that the
driver
is not threadsafe... Would you try these two experiments?
1 - Alter the weblogic server to define the pool to have only one connection,
ie: initial capacity = 1 and max capacity = 1. Let me know if the
problem
is still there.
2 - Alter the application code you run in the server to get a connection
directly
from the driver, just like the standalone code.
Let me know...

Hi Almir.
I highly suspect the RDB driver of a bug where re-using a given Prepared
Statement
will sometimes produce an empty result set. Weblogic will cache your
prepared statements
so when you call prepareStatement() we may transparently return you
a
previously-used
statement for the same SQL and arguments.
To prove my theory, please do these two things:
1 - Define your pool's statement cache to be of size zero. This should
make the problem
go away.
2 - In a standalone program, you can create a given PreparedStatement,
and rerun it in
a loop, and see if it ever returns an empty result set. I will showyou
how to include
the code we do to refresh the statement before reuse:
try
Class.forName ("oracle.rdb.jdbc.rdbThin.Driver");
Connection conn = DriverManager.getConnection("jdbc:rdbThin://<database_name>","<user>",
"<pass>");
String sqlStatement = "SELECT TABEL1.COLUMN1, TABEL1.COLUMN2,
TABEL2.COLUMN1
FROM TABEL1, TABEL2 WHERE (TABEL2.COLUMN2= TABEL1.COLUMN3) AND (TABEL2.COLUMN1
= ?)ORDER BY TABEL1.COLUMN1";
PreparedStatement ps = conn.prepareStatement(sqlStatement,
ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
for (int i = 0; i < 100; i++)
ps.setObject(1, new Integer(1));
boolean result = ps.execute();
ResultSet rs = ps.getResultSet();
// check result set here
rs.close();
cleanUpStatementForReUse(ps);
ps.close();
conn.close();
catch (Exception ex)
System.out.println(ex);

Hello everybody,
we are developing an application for Bea WebLogic Application Server8.1. This
application uses data from an existing database. This is an OracleRDB 7-1.220
database. Because the WebLogic AS does not include a JDBC driver forthis type
of database we got one from Oracle: RDBJDBC71. I installed this driverand tested
it by using a standalone Java application which executes a number
of
SQL statemens.
This test was satisfying, no problems occured.
Then, in order to use it within the application server, I defined
a
JDBC Connection
Pool in WebLogic with corresponding Data Source. And it worked, ourapplication
could connect with the database and execute the needed transactions.
But after a while we noticed a realy strange problem. When a particularSELECT
SQL stament is executed we expect a list of 6 records as result. Butsometimes
the returned resultset is just empty. I tried this hundreds of times.No error
or exception occurs but sometimes the response is correct and sometimesnot.
In the first place we thought that the JDBC driver was causing thisproblem but
then I executed the same SQL Select statement within a Java stand-aloneapplication
(and not using the Application Server) and the result was correct.Repeating this
hundreds of times did not change the outcome, the given resultset
was
always correct.
I tried reconfigurating the Connection Pool in different ways but
it
did not make
any difference: sometimes it worked and sometimes it didn't.
Here below you can see the code samples of both implementations.
Stand-alone:
try
Class.forName ("oracle.rdb.jdbc.rdbThin.Driver");
Connection conn = DriverManager.getConnection("jdbc:rdbThin://<database_name>","<user>",
"<pass>");
String sqlStatement = "SELECT TABEL1.COLUMN1, TABEL1.COLUMN2,TABEL2.COLUMN1
FROM TABEL1, TABEL2 WHERE (TABEL2.COLUMN2= TABEL1.COLUMN3) AND (TABEL2.COLUMN1
= ?)ORDER BY TABEL1.COLUMN1";
PreparedStatement ps = conn.prepareStatement(sqlStatement,ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
ps.setObject(1, new Integer(1));
boolean result = ps.execute();
ResultSet rs = ps.getResultSet();
// Result set is here always filled!!!!
rs.close();
ps.close();
conn.close();
catch (Exception ex)
System.out.println(ex);
Application server:
try
Context ctx = new InitialContext();
Object object = ctx.lookup(data_store_name);
DataStore ds = (DataStore)object;
Connection conn = ds.getConnection();
String sqlStatement = "SELECT TABEL1.COLUMN1, TABEL1.COLUMN2,TABEL2.COLUMN1
FROM TABEL1, TABEL2 WHERE (TABEL2.COLUMN2= TABEL1.COLUMN3) AND (TABEL2.COLUMN1
= ?)ORDER BY TABEL1.COLUMN1";
PreparedStatement ps = (PreparedStatement)conn.prepareStatement(sqlStatement,
ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
ps.setObject(1, new Integer(1));
boolean result = ps.execute();
ResultSet rs = ps.getResultSet();
// Result set is here sometimes empty !!!!
rs.close();
ps.close();
conn.close();
catch (Exception ex)
System.out.println(ex);
Any sugestions are welcome.
Thanks.
Almir.I have had the same problem as you with sporadic results for queries with RDB Drivers. Were you able to solve it and if so how?

Blob problem (Image storing or Currupted )
AOA!
I am working as a developer in a companey. we made a database for HRMS. In this database there is a table EMPLOYEE with a column PICTURE of type BLOB. We were using oracle 8i initially but when we migrate to oracle 9i, we are facing a problem in image storing. The situation is, database showing ur previously stored images (those have stored in oracle 8i) but when we save a new image in that table or any other table it seams to be saved but cannot retrived. I mean when we issue a query
SELECT EMP_ID FROM EMPLOYEE WHERE PICTURE IS NOT NULL;
It shows the new inserted records too (thats shows us that picture has been inserted) but when we issue query from a forms6i application it didnt show any image. In case of report, when we try to query a record which newly inserted with image, it says some thing like REPORT IS UNABLE TO SHOW IMAGE FORMATE etc.
The situation is for all table and all schema which is indicating us may be it is some thing due to oracle 9i headen technique or due to miss managment by us. we dont have DBA in our companey.
Please help us in this regard. We will be thankfull to you.

Dont reply to above mantioned email my actual email account is [email protected]I think that both your SQL is wrong and your intended use is wrong. According to the SQL reference, the following seems to be a simplified definition that seems to match what you're trying to do. UPDATE <table> SET <column> = <expr>. So PROPERTIES should be a <table> of some kind and X should be a <column> of that table. This changes your PreparedStatement to *"UPDATE PROPERTIES SET X = ? WHERE NAME = ?"* Then you can do ps.setBlob(1, b) and ps.setString(2, ...). Because your statement is DML you must do ps.executeUpdate(). So your code might look something like this.
Blob b = ...;
String x = ...;
ps = c.prepareStatement("UPDATE PROPERTIES SET X = ? WHERE NAME = ?");
ps.setBlob(1, b);
ps.setString(2, x);
int i = ps.executeUpdate();
The executeUpdate() returns the row count (i.e. number of rows) of your DML statement. Try that and see if it helps. -

Hi All,
i have a problem with BLOB data type. i just create a base table block thru wizard. i have one BLOB field in my table. i use GET_FILE_NAME and READ_IMAGE_FILE to store image in base table block field and press commit. it shows 1 transaction completed. when i query record it cannot shows any record. i checked it from SQL/PLUS, it shows no record in table (select count(*) from mytable) . when i use LONG RAW type its work. i'm using ORACLE 9i database and forms 6i rel 2.
plz tell me what i can do in this regard.
Thanks in advance
ShakeelHello there,
i have created a table(with 3 columns) one blob column, i commit one record as you have said and i saved it.
(i) The sql don't display
(ii) On forms it is showing
(iii) i have set item property (image), if you set any other accept except image or oracle defined then it will not display.
with best regards,

Hello,
The problem that i have is that i want to insert a file residing in the network into the oracle database into a blob field and again read it from the database and show it ie either insert it into a file directly and then open it using the correct editor or open it directly. I am using java along with it but i am basically stuck on the database side.
I am sending the code which i have written till date
i basically need to know
1)the syntax i am using to interact with the database is right ie where is the error in the code
2)provided that is ok whether my overall code is on the right track.
The error message i am getting:
java.sql.exe:ORA-06550 line col22
PLS 00302: Component GETCHUNKSIZE must be declared
ORA-06550 line1 col 7

System.out.println(ex.toString());You are probably better off using BLOBs rather than BFILEs. The main reason for this is that with BLOBs data integrity between file and its meta data in the database are managed and protected by the RDBMS. BFILEs are useful for legacy systems where the files already exist in some form of meaningful and managed structure that needs to be preserved.
There is a down side to BLOBs and that is performance - BLOBs are relatively slow to load into the database. However, its not too bad and the performance of extracting BLOBs out from the database is quite reasonable the bottleneck is more likely to be your LAN.
In order to use BLOBs it is important to have the right class libraries involved. For BLOBs you must use the classes12.zip (supplied with the database) for JDBC2 support and furthermore put this class high up the list of class libraries if you do not you may find that your code compiles but raises a runtime exception about invalid data types; this is because the wrong definition of the Blob class is being picked up.
Assuming that you are using BLOBs then the following describes the techniques for storing files as BLOBs in an Oracle database.
LOADING BLOBS
Assuming that you have a table with a BLOB column in it then to load a BLOB you must first create the record containing the BLOB by inserting a row into your table with the value of the BLOB column set to EMPTY_BLOB( ) (PL/SQL built in):
INSERT INTO tablex( col1, col2, colBLOB )
VALUES( val1, val2, EMPTY_BLOB() )
Then you must row lock this record and obtain the LOB locator for the BLOB just created:
stmt = connection.createStatement();
query = "SELECT colBLOB FROM tablex WHERE ... FOR UPDATE OF colBLOB";
ResultSet lockLOBSet = stmt.executeQuery(query);
At this point you should be able to use lockLOBSet.getBlob(1) to create a binary stream to load the BLOB directly into the database. Under Java Developer 2 I could never get this to work and havent tried since with Java Developer 3. Instead I used the PL/SQL DBMS_LOB package and did it using JDBC; this assumes that the file has been loaded into a buffer binaryFile and note that the maximum chunk size that dbms_lob.write can be called with is 32K:
blobLoc = lockLOBSet.getBlob(1);
while(amountWritten < fileSize)
if ((amountWritten + writeAmount) <= fileSize)
writeAmount = 32000;
else
writeAmount = fileSize - amountWritten;
System.arraycopy(binaryFile, amountWritten, buffer, 0, writeAmount);
CallableStatement cstmt =
connection.prepareCall("{call dbms_lob.write(?, ?, ?, ?)}");
cstmt.setBlob(1, blobLoc);
cstmt.setLong(2, writeAmount);
cstmt.setLong(3, amountWritten + 1);
cstmt.setBytes(4, buffer);
cstmt.execute();
cstmt.close();
amountWritten = amountWritten + writeAmount;
EXTRACTING BLOBS
Binary streams do work when it comes to reading BLOBs out of the database so things are a whole lot simpler probably worth trying it with loading BLOBs now as well.
ResultSet queryLOBSet = statement.executeQuery(query);
if(queryLOBSet.next())
lobSize = queryLOBSet.getInt(1);
blobLoc = queryLOBSet.getBlob(2);
BufferedInputStream bi;
blobBuffer = new byte[lobSize];
bi = new BufferedInputStream(blobLoc.getBinaryStream());
amountRead = bi.read(blobBuffer);
bi.close();

Hi All,
i upload an image from asp to blob field,but i can't display the image in asp.
while i write an image from vb to blob ,i can display the image.
i have read the sample code Use interMedia with OO4O and Microsoft IIS to load and retrieve rich content in InterMedia sample. the code have the same problem.
i don't know what to do.
help me.

I believe they work different from imagebuttons. Just crate a page and add an adrotator control to it and read the images from some xml file. I can send you the code. -
A J2EE problem from an International Bank EJB-RDB remapping problem
Background Information:
We are going to deploy a J2EE project with DB2 V7.1 as the backend database server. However, the project is developed using WSED and initially assumed DB2 V.8 will be used as the database server. The inconsistency of DB2 version have us to make some amendments on the project. To simplify the scenario, what we do is to truncate the table/column name with length >18 to 18 defined in all .tblxmi, ... for EJB-RDB mapping. After we rebuild the project and deploy it in WAS 5.1, the following error occured,
CNTR0020E: Non-application exception occurred while processing method "populateSystemCache" on bean "BeanId(eFOSt
0#eFOS-Session.jar#SystemService, null)". Exception data: javax.ejb.TransactionRolledbackLocalException: ; nested exception is: com

at COM.ibm.db2os390.sqlj.jdbc.DB2SQLJConnection.prepareStatement(DB2SQLJConnection.java:1580)
We are sure that we have made all the necessary truncations for the table/column. We discovered that some of the .class file, e.g. SystemBeanFunctionSet_71684028.class, was generated under the directory ../websphere_deploy/DB2UDBOS390_V71_1 after we rebuild the project. Many column names with length >18 were found there, such as ACTUAL_MONTH_END_DATE.
PreparedStatement pstmt = null;
try
pstmt = prepareStatement(connection, "INSERT INTO FAK.SYSTEM (SYSTEM_CODE, ACTIVE_FLAG, SYSTEM_NAME, BUSINESS_DATE, LAST_BUSINESS_DATE, NEXT_BUSINESS_DATE, REGION_CODE, MONTH_FLAG, ACTUAL_MONTH_END_DATE, LOCAL_COMPANY_CODE, LOCAL_BRANCH_CODE, LOCAL_COUNTRY_CODE, LOCAL_CURRENCY_CODE, FUNDING_CURRENCY_CODE) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)");
String tempString = (String)inputRecord.get(0);
May I know what those .class file (with number prefix in the file name)for and how can we solve the problem?
Thanks a lotPut it simply, is there any method using WSED to
deploy the project using DB2 V.7.2 if the project is
assembled using DB2 V8 and no java source is
available ???If you are not making use of any functions specific to DB2 V8 how does it matter for you? The difference only lies in the DataSource configuration or something like that but certainly not on your java code(If you have not done anything specific to V8).Your problem sounds me like as suggested you have an extra/lesser parameters(?) or checkout the parameter that you are passing in is not overflowing any columns. -
Tomcat 4.1 Oracle Blob problem using apache commons DBCP
Hi all,
We are using Tomcat 4.1.12, Java 1.4.x and trying to take advantage of the connection pooling that comes with Tomcat(the apache commons DBCP).
We are connecting to a oracle database.
Works fine for everything EXCEPT Blobs. We have a servlet that serves images from Oracle, that works fine when it doesn't use the connection pooling, but throws an exception when we call the
ERROR: Class:DisplayGraphic Method:processRequest(HttpServletRequest request, Ht
tpServletResponse response)
Exception: org.apache.commons.dbcp.DelegatingResultSet
DataSource ds = (DataSource)ctx.lookup("jdbc/db_connection");
Connection conn = ds.getConnection();
PreparedStatement pstmt = null;
ResultSet rs = null;
pstmt = conn.prepareStatement("SELECT graphic FROM graphics WHERE graphic_id = 1");
rs = pstmt.executeQuery();
if(rs.next())
oracle.sql.BLOB oBlob = ((OracleResultSet) oRS).getBLOB("GRAPHIC");
InputStream oIS = oBlob.getBinaryStream();
... etc etc...
}Any ideas?
Cheers,
Alex.solved the problem.. i was using getBLOB instead of
getBlob
doh..Hi Alex,
your problem is very interesting for me because I have a similar problem and your identical configuration...
the instruction
oracle.slq.BLOB aBlob = ((OracleResultSet)super.mRs).getBLOB("BLOBBONE")
causes this:
java.lang.ClassCastException: org.apache.commons.dbcp.DelegatingResultSet
To resolve this, I changed, in server.xml , the factory
<parameter>
<name>factory</name>
<value>org.apache.commons.dbcp.BasicDataSourceFactory</value>
</parameter>
with:
<parameter>
<name>factory</name>
<value>oracle.jdbc.pool.OracleDataSourceFactory</value>
</parameter>
and magically all works fine...
But the question is... Why doesn't it work with the standard factory???
There is a problem in the CLASSPATH that I don't see?
Any suggestions is welcome!
Thanks in advance!

2.3.0b3 and PointBase Blob problem.
The schema tool generates a BLOB with a maxsize of 1 byte in PointBase for
fields with the "blob" extension. This is of course too small, and results
in a "data right truncation" exception (from PointBase), when an insert is
attempted. The column-length extension element does not affect the BLOB
size. Is there some workaround?
-Maciej SzeflerI'm experiencing some additional problems with PointBase. It seems that the
"drop" action in schema tool does not work correctly (the syntax for
dropping the indexes is incorrect):

The SQL that caused this error is:
DROP INDEX REQUESTJDOIMPL__RESPONSESXJDOX;
DROP INDEX REQUESTJDOIMPL__RESPONSESX_REX;
DROP TABLE REQUESTJDOIMPL__RESPONSESX;
DROP TABLE REQUESTJDOIMPLX;
DELETE FROM JDO_SCHEMA_METADATAX WHERE CLASSNAMEX =

DROP TABLE RESPONSEJDOIMPL__PAYLOADX;
DROP TABLE RESPONSEJDOIMPLX;
DELETE FROM JDO_SCHEMA_METADATAX WHERE CLASSNAMEX =
'com.fs.wf.impl.jdo.ResponseJdoImpl';
This problem is not that big of a deal since dropping the tables drops the
indexes, but the BLOB column creation issue is a big pain because I have to
rewrite the SQL in order to increase the BLOB size.

Hi,
Tough problem it seems.
I have a database with BLOB datatype and various files of various formats like pdf, office, txt.
Most of these files blob are properly displayed using the following PHP script
<?
$conn = OCILogon ("","","");
$sql = "";
$stmt = oci_parse($conn, $sql);
oci_execute($stmt)
or die ("Unable to execute query");
while ($row = oci_fetch_array($stmt)) {
$id = $row['0'];
$blob = $row['1'];
$filename = $row['2'];
header("Content-type: application/octet-stream");
header("Content-disposition: attachment; filename=$filename");
echo "$blob -> readfile()";
OCIlogoff ($conn);
?>
When the display doesn't work, I have the following characters displayed.
JAL Ø 'Oh3Â.
Ä4á Bá Øp | €ÏðH
# a'hÐ !
C# ¸«ýÿ
Ã% Ùt¾a1(TM)Læ"Y'Þq9 Nç"Ùôþ A¡Pè"Z5 Ø¥'€ b H ð /áò m@ - ÂÁÀ ª¾à X£öP 0 'P' ª9oZ%¢vk'~P ²ÞooûÕÞ l# ¤°Ü$/ fÂÃ18l^"J » ±õèÌ8Å--+æaùË<0Ý--
The most probable problem would be the Byte Order Mark problem known from PHP http://bugs.php.net/42312 but I am not sure.
I just don't get it. The enconding of the database is ISO. Why some documents are absolutely fine, why some are not?
Any help would be very much appreciated.
Edited by: user13013984 on 21 avr. 2010 13:10Hi
Thanks for replying. Data storage seems fine, I have a data presentation issue. The binary cannot be read, the file format isn't recognized.
When I try the SQL you submitted I get this :
Erreur SQL : ORA-00932: types de données incohérents : NUMBER attendu ; BINARY obtenu
00932. 00000 - "inconsistent datatypes: expected %s got %s"
For example, some word documents stored as long raw work perfectly fine, some cannot be read. No txt files can be read. Some Excel files work fine, some don't.
There are no Office versions differences between them.
Is there any tool/code capable of reading any long raw datatype? -

GeorgeHi Omar,
Could anyone tell me how to insert a file (say a word doc., or a PDF or a text document) into a column of a table of type BFILE or BLOB. I know that it is possible to map to the physical file on the filesystem thru logical directory creation. But, would like to know how to insert a file into the column and use it later for retireval, string searching, etc. from the queries. Is it thru SQL*Loader? Could u explain me(with example, if poss.) how to do this with the loader utility?
Pls guide me thru this.
Thanks!

Sanjay
