Inserting and updating a BLOB field

Friends I want my application (Oracle is the backend) to look for a character in a BLOB field and then replace it with the desired character.
Can some one give me some example of retrieving and updating a BLOB field

Examples are in Oracle Technet: http://otn.oracle.com/
In this forum I saw also some examples and in your local Oracle Client Installation you find under $ORACLE_HOME$/jdbc/demo/ examples.

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:
<cfset file_mime = Lcase(Right(postedXMLRoot.objname.XmlText, 3))>
<cfif file_mime EQ 'jpg'><cfset file_mime = 'jpeg'></cfif>
<cfset file_mime = 'data:image/' & file_mime & ';base64,'>
<cfset image64 = ImageReadBase64("#file_mime##postedXMLRoot.objbase64.XmlText#")>
<cfset ramfile = "ram://" & postedXMLRoot.objname.XmlText>
<cfimage action="write" source="#image64#" destination="#ramfile#" overwrite="true">
<cffile action="readbinary" file="#ramfile#" variable="image_bin">
<cffile action="delete" file="#ramfile#">
<cfquery name="InsertImage" datasource="#datasource#">
INSERT INTO test_images
image_blob
SELECT
<cfqueryparam value="#image_bin#" cfsqltype="CF_SQL_BLOB">
FROM dual
</cfquery>

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.

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.

Problem with ojdbc14.jar (oracle10g Rel. 2 driver) in updating a BLOB field

Hello All,
Our web application uses oracle10g Release 2 jdbc driver with websphere 5.1.1.4 and oracle 9i. When it tries to update a BLOB field in the database updation is successful but it is updating that field with a null value. So rest of our application fails as this value is becoming null. We use an entity bean to update this table and websphere uses a prepared statement to update this table. Just before setting this BLOB field using setBinaryStream() on prepared statement I am printing to see whether it is null or not as shown in the code snippet below. And it is printing it correctly as non null. But after execution of the prepared statement some how the value stored in database is null.
Is this a known issue with this driver? Does any one know work around or a solution to this? We have 3 BLOB fields in that table. Is that a problem? If we separate these BLOB fields into separate tables will the problem be solved? Any input on this is very much appreciated.
// For column ORIGINAL_CONTENT
byte[] tempbyteArray;
tempbyteArray=(byte[])inputRecord.get(25);
if (tempbyteArray == null) {
System.out.println("DqPageBeanFunctionSet_f9c724af: tempbyteArray NULLLLLLL");
} else {
System.out.println("DqPageBeanFunctionSet_f9c724af: orig tempbyteArray length: " + tempbyteArray.length);
if(tempbyteArray != null) {
pstmt.setBinaryStream(25,new java.io.ByteArrayInputStream(tempbyteArray),tempbyteArray.length);
else pstmt.setNull(25,java.sql.Types.BLOB);
Thanks & Regards,

I have similar problem and I solved it using ojdbc14.jar oracle9i version.

Updating a blob field in access db

hi all
i need to update a blob field (containing images) in an access db
i tried with this code but didn't work:
PreparedStatement ps=c.prepareStatement("UPDATE "+tab_name+" SET "+col+" = ? WHERE "+key+"="+key_val);
                        ps.setBytes(1, rs.getBytes("F_VAL"));anyone could help me?
thanx
sandro

ok, i changed my code in this way:
ResultSet rs2=to.executeQuery("SELECT * FROM TABLE WHERE KEY= 'mykey'");
                            if(rs2.next())
                                Blob blob=rs2.getBlob("F_VAL");
                                InputStream in=blob.getBinaryStream();
                                rs2.updateBinaryStream(col, in, in.available());
                                rs2.updateRow();
                            }and nothing happens, my file in this row isn't updated!!!
if i write
ResultSet rs2=to.executeQuery("SELECT * FROM TABLE WHERE KEY= 'mykey' for update");i get an SQLEXception that tell me that access can't implement this feature
anyone could help me?
it's not possible to update a Blob in access?
thanks

"reproc: Insert and Update failed on" replicated table

Hello, I've published a new publication item on an Oracle Lite Server (9i and mobile server 5.0.2.10).
After inserting records on the server replicated table (Table1), when I try to sync some devices, I have the following error message on the client PDA "reproc Insert and Update failed on " Table1.
If I empty the server table's records, then the client PDA syncs OK.
Can someone refresh me with the cause of this error ?
Thank's in advance.

Hi,
This is my actual requirement.
During the updates i.e update process and delete process, if the filed status is changed to 'O', '0' or ' ' in SAP, then those records in Oracle should be deleted.
if the field status is changed to other than 'O', '0', or ' ' SAP, then those records needs to be updated with the remaining information
How do XI Know that these fields are changed in the SAP table to perform delete ,is some notification required when there is change in SAP Table through proxy ?

Can we use both INSERT and UPDATE at the same time in JDBC Receiver

Hi All,
I would like to know is it possible to use both INSERT and UPDATE at the same time in one interface because I have a requirement in which I have to perform both the task.
user send the file which contains both new and old record and I need to save those in MS SQL database.
If the record exist then use UPDATE otherwise use INSERT.
I looked on sdn but didn't find any blog which perform both the things at the same time.
Interface Requirement
FILE -
> PI -
> JDBC(INSERT & UPDATE)
I am thinking to use JDBC Lookup but not sure if it good to use for bulk record.
Can somebody please suggest me something or send me the link of any blog or anything to solve this problem.
Thanks,

Hi ,
          If I have understood properly the scenario properly,you are not performing insert and update together. As you posted
"If the record exist then use UPDATE otherwise use INSERT."
Thus you are performing either an insert or an update which depends on outcome of a search if the records already exist in database or not. Obviously to search the tables you need " select * from ... where ...." query. If your query returns some results you proceed with update since this means there are some old records already in database. If your query returns no rows you proceed with "insert into tablename....." since there are no old records present in database.
Now perhaps the best method to do the searching, taking a decision to insert or update, and finally insert or update operation is to be done by a stored procedure in MS SQL database. A stored procedure is a subroutine available to applications accessing a relational database system. Here the application is PI server.   If you need further help on how to write and call stored procedure in MS SQL you can look into these links
http://www.daniweb.com/web-development/databases/ms-sql/threads/146829
http://www.sqlteam.com/article/stored-procedures-parameters-inserts-and-updates
[ This part you can ignore, Since its not sure that you will face this situation
    Still you might face some problems while your scenario runs. Lets consider this scenario, after the stored procedure searches the database it found no rows. Thus you proceed with an insert operation. If your database table is being accessed by multiple applications (or users) other than yours then it is very well possible that after the search operation completed with a null result, an insert/update operation has been performed by some other application with the same primary key. Now when you are trying to insert another row with same primary key you get an error message like "duplicate entry not possible for same primary key value". Thus you need to be careful in this respect. MS SQL has a feature called "exclusive locks ". Look into these links for more details on the subject
http://msdn.microsoft.com/en-us/library/aa213039(v=sql.80).aspx
http://www.mssqlcity.com/Articles/Adm/SQL70Locks.htm
http://www.faqs.org/docs/ppbook/r27479.htm
http://msdn.microsoft.com/en-US/library/ms187373.aspx

http://www.mollerus.net/tom/blog/2008/03/using_mssqls_nolock_for_faster_queries.html
    There must be other methods to avoid this problem. But the point is you need to be sure that all access to database for insert/update operations are isolated.

Oracle forms 10g,multiple insert and update problem

Hi,
I have tabular form(4 records displayed) with one datablock(based on a view).
After querying the form could not update all the records but only first record value can select from LOV.
I called a procedure in in-insert and on-update
The query is lik this
PACKAGE BODY MAPPING IS
     PROCEDURE INSERT_ROW(EVENT_NAME IN VARCHAR2)
     IS
     BEGIN
          IF (EVENT_NAME = 'ON-INSERT') THEN

               CREATION_DATE,LAST_UPDATED_BY,LAST_UPDATE_DATE,LAST_UPDATE_LOGIN)
               VALUES
               (     :XX_REC_MAPPING.OFFICE_CODE,
                    :XX_REC_MAPPING.COLLECTION_ID,

          ELSIF (EVENT_NAME = 'ON-UPDATE') THEN
          UPDATE     XX_REC_MAPPING
          SET BRANCH_CODE=:XX_REC_MAPPING.OFFICE_CODE,
                    COLLECTION_ID=:XX_REC_MAPPING.COLLECTION_ID,

                    WHERE ROWID=:XX_REC_MAPPING.ROW_ID;
          END IF;
     END INSERT_ROW;
END MAPPING;
Whether the table gets looked or sholud i use some other trigger or loops ?
someone suggest me how to edit this query for multiple update.
Thanks
sat33

I called a procedure in in-insert and on-updateWhy are you writing this code in the first place? If you have a block based on an updatable view, just let Forms do the inserts and updates.
If it's not an updatable view, use instead of triggers on the view.
See this current thread too:

Kindly Regards...

You might be better off combining into your attack the use of user_dependencies. This will tell you what objects e.g., code is dependent on your table and then you can search the source of those modules for inserts and updates into the table. Even then you'll never be sure, especially if dynamic SQL is used as the statement may be pieced together from various bits if strings, as then user_dependencies won't contain the reference.

Not Properly Insert and Update in ODI interfaces

Dear Brothers,
The records are not inserting and updating even the CDC captured in the journal in one of my package. But, stopped and execute again then there is inserts and updates. I am not able to understand where the problem is. Can u suggest regarding the issue.

Dear Bro,
I am capturing CDC using consistent set. I am using (LKM SQL to DB2 UDB). While executing the package, the records are locked and extend window, but there is no inserts and updates into the database. It is throwing error as row index out of range while running the query. The query is running in Source Stage for ex. RTO_STAGE.JV$NUMGEN. query is triggering but records are not properly inserted and updated in the target.
First time i saw in the CDC table, there was some 10 records available while executing no insert and update. Then, i stopped it and execute it again at that time i checked in the CDC table ie., the same table, but there was only 2 records available in CDC the old records were disappeared.
I dont know the exact issue? My colleague is telling may be SNP tables not refreshing. Kindly suggest any solution.
