How Data Is Written In Table
Nov 3, 2012
I have a table which contains 2 main columns apart from other columns. These two columns are REC_ID and ENTRY_DATE_TIME.
In this table data is inserted through a data load process using SQL Loader. REC_ID is populated to table through a sequence and ENTRY_DATE_TIME is populated as a sysdate.
select rec_id, to_char(entry_date_time, 'dd-mon-yyyy hh24:mi:ss') entry_date_time from itpcs_grt_oa_tran_rdpk_stock order by 1;
REC_ID ENTRY_DATE_TIME
1 12-oct-2012 07:06:23
2 12-oct-2012 07:06:31
3 12-oct-2012 07:06:35
4 12-oct-2012 07:06:21
5 12-oct-2012 07:06:32
If we see the data, then time for REC_ID 4 is less than REC_ID 3.
Now the question is if REC_ID is populated through a sequence then sequence 3 must have been created before REC_ID 4 and if so then why the ENRTY_DATE_TIME of REC_ID 4 is less than REC_ID 3.
Further to the question, how data is written in tables. What steps are performed by at database level when we any DML(insert) is performed.
My DB Version : Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit

db environment: 11g
recovery catalog: 10g
I am trying to find if there is a way to know how much data has been written on tape on a 'in progress' rman backup. rman session is also connected with recovery catalog.
is there a way to find-out how much data is transferred per rman channel onto tape? what is backup speed we are getting?

I just want to know whether can i create a trigger where the sysdate can be automatically written into a table? for ex: if to_char(sysdate,'HH24:MI:SS') = 18:00:00 then it should be written in a table..?? is there anyother way instead of triggers??

I think there is no limit for number of procedures and functions can be written in a package, but little much confusion.
What is the maximum number of Procedures and Functions can be written in a package? is such type of limit is there or not ?

SQL> CREATE OR REPLACE TRIGGER TRI_COMPL_FEATURES
2 AFTER INSERT OR UPDATE ON COMPLEMENTS FOR EACH ROW
3 DECLARE
4 v_fno NUMBER;
5 v_tab VARCHAR2(30);
6 v_unique_id VARCHAR2(40);
[code]....
Trigger created.When I am trying to insert into complements table it is throwing error as follows:
SQL> insert into complements values(19,NULL,'5',6,7,NULL,'W2023648',NULL,NULL);
insert into complements values(19,NULL,'5',6,7,NULL,'W2023648',NULL,NULL)
*
ERROR at line 1:
ORA-20010: ORA-04091: table TEEMNGWS.COMPLEMENTS is mutating, trigger/function
may not see it
ORA-06512: at "TEEMNGWS.TRI_COMPL_FEATURES", line 19
ORA-04088: error during execution of trigger 'TEEMNGWS.TRI_COMPL_FEATURES'
I can understand that I am trying to perform DML operation(i.e select) on table which trigger is fired.But how can I implement the same logic when AFTER INSERT OR UPDATE trigger is written.

I have encountered ORA-01555 and trying to find what caused the issue.
#UNDO parameters
undo_management AUTO
undo_retention 0
undo_tablespace UNDOTBS1
set pagesize 25
set linesize 120
select inst_id,tuned_undoretention,to_char(begin_time,'MM/DD/YYYY HH24:MI') begin_time,
[code]...
at the end you can see there is one occurance of ORA-555, but no Unexpired or expired blocks were over written .why Oracle didnt try to use them ?

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.

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,20120524,01,01,9999AMP02,1.1262240,M,0.6397380,M
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));
[code]....
, which does not work at all.

Here is my problem, i need to create some files with my own format(let say 5000 records each) from a huge data table (May contain 5 Million records). And i want this creation to be multi threaded.
so how can i form queries efficiently to fetch records like 1..5000 and 5001..10000 and so on. I can form some thing like select * from table where rownum<5000 and not exists ( already fetched records) . but it is not the efficient one.

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.

CREATE TABLE SALESHIST
(
PRODUCT VARCHAR2(30 BYTE),
Q1 VARCHAR2(30),
Q2 VARCHAR2(30),
Q3 VARCHAR2(30),
Q4 VARCHAR2(30)

2 from user_segments
3 where SEGMENT_TYPE='TABLE'

The countries table is missing in user_segments data dictionary view.But I can queries the countries using select statement.
SQL> SELECT * FROM COUNTRIES;
CO COUNTRY_NAME REGION_ID

We need to load data from index by table to table.Below code is working fine.
declare
query varchar2(200);
Type l_emp is TABLE OF emp%rowtype INDEX BY Binary_Integer;
rec_1 l_emp;
begin
[Code]....
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)
as
query varchar2(200);
source varchar2(200);
Type l_emp is TABLE OF emp%rowtype INDEX BY Binary_Integer;
rec_1 l_emp;
[Code]....
Its throwing. How to implement this scenario .
