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?
what could be effective data type to store large integer values like, 50,000; 10,000,000 etc.?

I am using oracle 11g express edition.
(1.) We have an Oracle 10g DB.
(2.) We want to store PDFs/MS Word docs inside BLOB column in a table.
(3.) We need to show PDF/MS Word content to the user, without opening the PDFs/MS World like we normally do (i.e. Using PDV reader/ MS Word).
(4.) i.e. We need to use SQL statements and
(a.) Get all contents of the PDF/MS WORD doc.
(b.) Search for specific strings inside these docs in the BLOB columns.
I have a table where user can store images in clob format.Need to convert the same image to blob and store in a dummy table.
I tried using this

I have oracle 11gr2 database on linux os. It's total sga size is 500mb only. Now, if uses wants read the 1gb of data from database, then there is no sufficient memory in buffer cache. so how it will works. the transaction will get successful or it will fail.And i have another doubt, does oracle can read the data from memory only or it can also read directly from disk.

I have encountered some problems in SQL I want to create a table with a bunch of prepared data. For ease of use, I choose to generate a SQL file which contains all the sql clauses used to create the table and insert the data. So all the data can only be inserted to a table using sql clause.
My questions:
1) If data of a column is large (for example, 1 M text), how to insert it using SQL, is there a piecewise method.
2) And how can I insert BLOB data using SQL clause.
What I what is to enclose all the operations in a single SQL file, and when the table is needed, just execute this SQL file.
My requirement is to get primary key column name and there values of a table and store in a stage table
create table easy(id integer, event_rowid integer,txn_rowid integer,txn_name varchar2(200));
begin
for i in 1..5 loop
insert into easy values(i,'777'||i,i||89,'Ris'||i||i);
[code]...
I was able to fetch primary keys and there values for a table and store them in stage table but only 1 record , I am stuck when there are more than 1 record Here is what i tried
SQL> SET serveroutput ON
SQL> DECLARE
2 V_prim_key VARCHAR2(2000);
3 l_tab DBMS_UTILITY.uncl_array;
[code]...
If you look at the above code in the execute immediate where condition i have used id=1, which is 1 records only but if i change id <3 then there will be 2 records and i will get below error ORA-01422: exact fetch returns more than requested number of rows
Other problem if there are 3 primary keys as in above case i am fetching there values 1 by 1 , is there any way if i can fetch those values once in for all data to be stored in stage table in below format
TAB_NAME V_PEIM_KEY V_PRIM_DATA DT

I Have to write a procedure which takes XML data and inserts into some tables.
If the XML format is fixed then i can use extract function for parsing and can insert into the tables.
But the problem is there is not fixed format for the xml.
Are there any built in packages which takes the xml data for parsing..
I have a PL/SQL procedure which gathers data from multiple places as well as calculates some data. I want to store all this in a materialized view.
So, I created an object type (I've shortened the definitions):
CREATE OR REPLACE TYPE mf_record_type AS OBJECT
(identifier VARCHAR2(6),
name VARCHAR2(100));
Then created the table type of the object:
CREATE OR REPLACE TYPE mf_table_type IS TABLE OF mf_record_type;
Then in the stored procedure defined a variable of the table type:
v_mf_record mf_table_type := mf_table_type();
Then I loop and populate the record type:
v_mf_record.EXTEND(1);
v_mf_record(x) := mf_record_type(v_rec.identifier, v_mf_detail.name);
When all that is done I try and create the materialized view:
EXECUTE IMMEDIATE ('CREATE MATERIALIZED VIEW mf_snapshot_mv AS
SELECT * FROM TABLE (CAST (v_mf_record AS mf_table_type))');
ORA-00904: "V_MF_RECORD": invalid identifier
Am I doing something wrong here? Can't I create the materialized view based on something other than a physical table?

how to tune qurey for coulumn wise data saved.because we have to join same table n number of times.for reference go through the following scnarios.
Suppose one table T1 is there and it has two column KEY and VALUE.if we are writing qurey for retriving desire result in row manner we have to join samae table no of times.
KEY Value
agreesWith true
id 1
assessment False
basisForDateOfProgression 1
bestOverallResponse 2
bestOverallUnknownComments data is ok
Qurey:
select * from (
select t.agreesWith from t1 t
)a
[Code]...
In this manner we can join upto bestOverallUnknownComments .so which method we follow to reduce the execution time and performance should be good.
I am facing a problem with utl_http.write_text in my pl/sql application. My requirement is to write data of size>32k. So I used a clob variable in write_text. But still it is showing numeric or value error when the data size is above 8k.

I have a query on , how to view the sample data from a very table which is large in size ( more than 10 million ).
I just need to see some sample data from a large table ( to see what kind of data which is application related ).
My question is :
Select *
from Sample_table
where rownum < 10
is this a Good way to view the sample data ?
I have understanidng that the rownum will be assigined to the rows once all the rows are reteived.
So what is the best way to view ?..I am not sure of any condition to put in the intial time of querying.

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.
I am very new to oracle and SQL.I am trying to create a store proc that will copy 14 day of data into a table and then truncate the original table. When i compile following code....

Scenario:
Our application is using a two instance, one for the live active data and the other for the reports data. We have a process which moves the data from the live instance to reports instance every night. In a single db environment the process is working without any issues. However when we move to the RAC environment the reports db's (insert) in large table get locked and we are unable to insert data to the reports db.
What we are performing is:
Insert into my_table_rpt select * from may_table_live@db_link_to_livedb;
Issues:
my_table_rpt get locked
We have found the workaround by disable locking in destination and subsequent to the insert enable locking
ALTER TABLE my_table_rpt DISABLE TABLE LOCK;
Insert the data to the reports database table
Then
ALTER TABLE my_table_rpt ENABLE TABLE LOCK
Question:
Why does the large destination table (my_table_rpt) get locked in the RAC environment?

I'm using few cursors to update my data and store it back to the same table. But for some reason the cursor seems to be picking obsolete data.
cursor c1
is
select distinct roles
from table1
where flag = '1';
cursor c2
is
select distinct roles
from table1
where flag = '1';
begin
for i in c1
loop
here im updating the roles im picking to to a suffix and role.
update table1
set role = suffix_role
where 'some condition';
end loop;
commit; -- committing so changes are visible for my next cursor.
for j in c2
loop
here im deleting all the roles that are not part of my comparing table.
delete from table1
where role = 'something';
But in my debugging table i see that its deleting roles present as input for first cursor, whereas it should actually pick data with suffix_roles.
I have a Data entry form which is a multirecord block;
Question: for example that form has 10 to 25 fields or columns more than that all the data has been entered, but before committing or saving that form i need to cross check the the data with a select query, whether the data entered is correct or not but before committing, that data it should be posted into that table if i find that one data is entered wrongly then i will modify that and again cross check and save the transaction permanently into the database table?
We have data archive scripts, these scripts move data for a date range to a different table. so the script has two parts first copy data from original table to archive table; and second delete copied rows from the original table. The first part is executing very fast but the deletion is taking too long i.e. around 2-3 hours. The customer analysed the delete query and are saying the script is not using index and is going into full table scan. but the predicate itself is the primary key,More info below
