I need to move data from non-partinioned table to partitioned. The volume is about 60 millions rows. What is the fastest way to do that? I think about pareller insert and nologging. What do you think about this? May data pump be faster?
View 4 Replies I have a table called Daily_usage (only 1 day data) which contains daily transaction records. After a day I have to move this data to another table named Daily_30days_usage table. this table contained the 30 days data. After 30 days the 31st day data should be deleted from Daily_30days_usage table.
How can I implement this requirement without INSERT statement?
I have imported data into database using sqlloader into flat table. Now I need to move the data from this table to another table. This is production system and I must keep it online. So I decided to make script that will move data in small chunks and commit frequently to avoid waits and table locks.
Regarding the script I have question. I can to the bulk load of rowids. Is it possible to optimize the insert and delete in similar way instead of doing insert/delete in loop for each rowid ?
declare
type t_rowids is table of rowid;
rowids t_rowids;
begin
loop
select rowid bulk collect into rowids from ims_old.values_f2 where rownum < 1000;

Doing this process from code is not an option and MUST happen automatically via triggers.The mutating trigger error can sometimes be avoided: URL....
I am trying to create a trigger which does the following : A flag in the initial able is set to Y. When this happens, the record needs to be inserted into a history table and then DELETED from the calling table.
It must happen in triggers, but I keep getting the mutating error.I have tried to use a Compound trigger, but with no luck and just dont really understand how to get this to work.

I have create Master block and a Detail block.When i am clicking on the Master block, then details records are displaying.But when i m moving from 1st record of detail block to 2nd record of master block, then detail block's data is not not displaying.It just firing the validation of detail block's first field.
when from Detail block (Cursor on the field Mapping code field) clicking on the 2nd records i.e Ord.No. =2 , at that time validation is getting fired.)

There is a requirement to make a table data in a database (eg: HR database) available in another database (eg: EMP database), instead of accessing it using database link. In EMP database(where data needs to be cloned), data will only be queried and no write operation will be done. Data in remote database (eg: HR DATABASE) will be occassionally fully truncated and reinserted. The plan is to do a similar truncate and reinsert of data (from HR database) into EMP database monthly once using dbms scheduler job. So basically data in just one table needs to be cloned in another database.
Question: For this situation, is a regular table or Materialized view the right choice to clone the table in EMP database and why? The table in HR database (remote database) is not very big.

But data from source table and target table is dynamic.Ex:In above code, emp(source) and target table is emp_b are static. But for our scenario is depends on the source table , target would change as below.If source is emp then target is emp_bIf source is emp1 then target is emp_b1 ............
create or replace procedure p(source in varchar2, target in varchar2)

View 2 Replies View Related"All data you create in this tablespace will be encrypted using an AES256 encryption key. You cannot encrypt an existing tablespace. To encrypt data, first create an encrypted tablespace, then use alter table move, CTAS or datapump import to move your data into the encrypted space. Remember to drop the old tablespace BUT not including datafiles. Use an OS schred program to remove the old datafile. If you are on ASM you may use the including datafiles option since you can’t schred files from the OS inside an ASM instance."
But i want to know why we should NOT drop the including datafiles, when dropping tablespace (so 'drop tablespace my_tbs including contents and datafiles'). So what option should we use when dropping tablespace?
Why we should use OS capabilities to remove the datafiles?
What happens if i remove the datafile when i drop the tablespace?

how to insert data in a table by deleting previous entered data and only inserting current data like:
CREATE TABLE test
(
name VARCHAR2(20),
id NUMBER
)
INSERT INTO test VALUES ('aaa',5500);
[code]....
I got two rows. now when I do insert statement I want to delete the previously stored data and only insert the current data like:
INSERT INTO test VALUES ('aaa',8);
INSERT INTO test VALUES ('aaa',9);
it must show aaa,8 and aaa,9 bt not the previous values.
NOTE: we can not do sth like: update set... where id = ... becoz the values are dynamic.
when i press when button pressed trigger, i want first the form will delete all the previous data and then populate the data from the table, that's why i used clear_block first, but this clear_code is not working here. my coding is given below
go_block('show');
clear_block(NO_VALIDATE);
declare
cursor c1 is select *
from qtr_demand order by 1;
begin
[code]..........
I am working on forms 6i. I have one data block based on table EMP.
Datablock-A: Empno, Ename, Sal
I have FIND Screen: Empno, Ename, FIND Button.
I can search the data through FIND Screen and populate data in Datablock A.
I am using below logic to search data through FIND Screen.
When-Button-Pressed(FIND Button): calling 'EXECUTE_QUERY'.
In Pre-query trigger of DatablockA:
copy(:FIND.EMPNO,'BLOCKA.EMPNO');
copy(:FIND.ENAME,'BLOCKA.ENAME');
It's working fine. But below case is failing.
Let us say, if i enter empno 10 (which is not there in database) in FIND Screen --> press FIND Button, it's showing up 'QUERY CAUSED NO RECORDS', Till this point it's working fine;. But after this, if i press CTR+F11 in block A, it's not pulling records. only this case it's not pulling records.
But if i enter something else in FIND Screen, if it returns any data, then if i press CTR+F11,it's pulling all records.
why it's failing to pull records if i try to query data in first case only.

I have written a java code which reads 2 millions of data under a particular column from CSV file and store it into a set. Now there is a table in Oracle database which contains 10 millions of records for that particular column. Now, I want to form a SQL query which select those records under that particular column from the database table which is in CSV file but not in database table. For e.g.
If I consider the CSV file name as employee.csv and it has column called employee_name under which the records are as follows
employee_name
---------------------
Sudip
Kaushik
Joyanta
Soumya
Ritesh
Gautam
And the database table name called cmp_employee and it has column called employee_name under which the records are as follows
employee_name
--------------------
Sudip
Kaushik
Joyanta
Soumen
Souvik
Sahoo
Now, the "SQL Query" should return ---- "Soumya, Ritesh, Gautam" this three names.
I need to import some data from .csv files. There is one file each day, so I want them to be automatically imported into the DB. This is the format it comes in:

DSM,LOD,20120524,01,02,9999AMP02,1.1315700,M,0.6450840,M
DSM,LOD,20120524,01,03,9999AMP02,1.1297880,M,0.6450840,M
I want this data to go into TEMP_TABLE. It then needs to reformatted as it goes from temp_table to my_table:
filename,readingID, field1,field2,date,num1,num2,meterid,read1,m1,read2,m2
so filename is the actual name of the .csv file that this row came from. And reading id is date, num1, num2, meterid combined. And the remaining fields coming from temp_table
This is what I have:
procedure import_data()
begin
TEMPFILENAME CHAR(60)='DSM_2010_Husky_Oil_20120525064122_20120525065011.csv';
create table temp_table
(dsm char(3),lod char(3),usage_date date,he char(2),reading char(2),loc_id char(9),mwh number(15,10),eormmwh char(1),mvar number(15,10),eormmvar char(1));

, which does not work at all.
