I have a table containing BLOB column which stores scanned images. Due to an application error, few extra data was padded with BLOB data and now we want to remove it.
The table count will be near to 10 million rows.
We need to remove data from 161byte to 167byte of the blob data. I tried to do with DBMS_LOB.ERASE.But it will create blank spaces for the removed data. Here we need to reduce the size of BLOB data by 6 bytes by removing data from 161bytes to 167 bytes.
We have table with number as datatype which starts with number 10 like 1056723. Here we need to update the first 2 digits which is 10 to 04.Digit 10 will be always constant across all the data.
select * from temp; id ---------- 1056723
After update, it should be
id ---------- 0456723
What function in pl/sql should be used for achieve the desired results.
I have made an application in forms 6i. Now i want if user can update, or modify the data it will required automatic authentication. Administrator will gives his password then the updation will continue otherwise rollback the transaction.
I have two different database servers where I need to migrate table data from one schema to another schema in batch wise for eg say 100 rows. I used BULK COLLECT with LIMIT. But to access BLOB data from table I have facing errors. What could be other approache to do the same.
here pc_work is a table containing BLOB data in sourse schema. I am fetch data from this table to table t1_test_work using dblink but not working
[ declare type array is table of test_work%ROWTYPE; L_DATA array; cursor C is select * from pc_work@prpctrg; begin open C; LOOP
Since XML-files only contain character data, we could/should store it in a CLOB, rather than a BLOB.
But, One of my friend having a table where a column is defined as bloband came to know that XML data are being stored. I searched for some article with keyword 'How to insert large XML data in BLOB' But did not work.How to store the large xml content in a Blob and How to extract it?
Below is the function code used to extract data from blob column. The function works fine when the blob data length < 2000 bytes. When it is more than, it is throwing an error as below.
Table name: mr_test Columns: id number seo blob

vlanke@tank_db> desc filetable; ID NULL NUMBER(6,0) FILE_CONTENT NULL
I am new to Database field.
- I created a table with 2 columns id (datatype as number) and file_content datatype as BLOB. - My question is under desc filetable; query why does it not show me a data type as BLOB. - create table query does not return any error to me. How do I verify that FILE_CONTENT column has datatype as blob.
I am getting the file using CLIENT_GET_FILE_NAME. I need to read the data from the .xsl file and convert it into blob. The file should not be stored in DB.
I use the oracle 10g database.I am trying to insert and retrive the image.Inserting an image is done.but while retrieving an image iam getting an run time exception in java "java.sql.sqlexception:general error".i am not able to understand this.
The code to insert the image is FileInputStream fi=new FileInputStream(f); int size = fi.available(); System.out.println("j"+size); byte b1[] = new byte[size]; i=fi.read(b1,0,size); System.out.println("i"+i); st.executeUpdate("insert into image1 values('b1',"+k+")"); when i am retrieving the image i tried like this ResultSet rs=st.executeQuery("select imagecolumn from tablename"); here iam getting an exception as i named above.
How can i convert data in NCLOB column to BLOB variable? NCLOB now is tored in UTF16. The data character set is ISO8859P2. Need to keep BLOB at unicode.
I am seeing some trailing characters in the coloumn when we are inserting Blob. I am doing SQLBindParameter with SQL_C_BINARY and SQL_LONGVARBINARY as InputOutputType and ValueType respectively.Do you see any problem in this. I get this problem when I am running Oracle 11 g client on an Windows 2008 Server 64bit.When the same set of query is fired from Windows 2003 Server 32bit with Oracle 10g it works fine and no trailing character gets inserted.
We will create a new instance in our production server, but this time, part of it's table structure has a BLOB data type (re: <column name> blob(3000)). It's our first time to handle this kind of Oracle data type. What would be my estimate size for it's default tablespace?
There is a customer_account table. It is partitioned by Range. In one of the partition, the range value is given wrongly, and irrelevant data sits in that partition.
How can i modify the range partition value and re-arrange the data ?
I am quite a beginner One of trigerred jobs is freezing and I have to reproduce the issue. Thing is about extracion and export data from one table to another (from Rating to Xtexport_table_1).
I want to build query which will fill xtexport_table_1 with values, partialy declared and partialy fetched from Rating tabble.
I figured out that that I have to get rid of all condition statements(IF, WHEN etc ), and just declare variables for some columns and then use a SELECT statement to fetch data.

We are adding support for barcode scanner in one part of our information system. So that the mechanics can add parts to an work orders bill of material themselves using barcode scanner to scan the part and enter the qty.
I can via SQL add a part to the bill of materials and reserve the part. But then the part needs to be issued to make it disappear from the stock.
I have found a table that contains information about the part and the bill of material, it has a column named "QTY ISSUED" I have tried via an update command to set the qty issued = 1 for the reserved part. The table is updated, and via SQL everything looks fine, but the part doesn't disappear from the stock. So my guess is that there is a trigger or function somewhere that I need for this.
I have a database in which a user xxxx is assigned a password 'bbbbb'.I want to change the password to the one which was used before which was 'aaaaa'.But when I change the password it was saying "Password cannot be Reused".So I checked in user profile and found out that password_reuse_time=unlimited and password_reuse_max=5.
So what I did was change the password 6 times to something else(Since it is 5) and then tried changing it to 'aaaaa' but still it is saying "Old password cannot be reused".
I am working on Oracle reports 6i. Just for R&D purpose I have opened REP file in notepad. In the notepad file I could find the queries which are there in the data model.
I did a small addition to the query and saved it in the same location. I tried to open the modified REP file from RWRUN60, but it is throwing me error saying "REP-0110- Unable to open file".
Original Query in data model: SELECT empno, sal, job, hiredate FROM emp;
Modified Query: SELECT empno, sal, job, hiredate FROM emp WHERE deptno in (10,30);
I am using 'Novell Sentinel Log Manager' to collect/fetch logs from my Oracle 11g R2.To enable auditing, first I did following:
login as sys, then SQL> create user testuser identified by "testuser"; SQL> grant connect to testuser SQL> grant dba to sharf SQL> grant CREATE SESSION to testuser; SQL> grant select on v_$session to testuser; SQL> grant select on v_$version to testuser; SQL> grant select on SYS.DBA_AUDIT_TRAIL to testuser; SQL> grant select_catalog_role to testuser; SQL> grant select any dictionary to testuser;
Now logon/logof of user 'testuser' are logged , as well as if testuser drops a table or creates a table, its also logged . but when 'testuser' insert a new record, this information does not logged ;( while I need to know exactly what was added SQL> insert into emp (empid, name, salary) values (10002, 'Ron', 6000)
likewise if 'testuser' modify/update an existing record it also does not logged. SQL> update emp set salary=700 where empid=10001;
which sql statements I have to execute to start auditing 'insert' and 'update', so that I know what was added/inserted and exactly what was updated/ changed/modify by user 'testuser'.
I am using the client system to change the setting and the time zone differs from that of production. Even though the job is scheduled to run at 5 AM it show the start date as 6:30 PM which is the client system time.
