I am trying to delete the one month data from the table , which contains the end customer sales data.The total data count in the table is 30 crores. And the data of one month is nearly 10 Crores.I am using oracle 10g , The date field to be used in the condition of delete is indexed.
After creating all the tables and the constraints, and inputting data to the table.. i want to delete everything. i try using drop table but it doesn't get rid of the constraints.
looking at my oracle DB schema I see that there are considerable number of tables that appear to be backup(!!) of other tables and don't ask me the reason why would some one create backup/temp tables in production.
All the tables almost occupy 7GB of space and I would like to get ride of them. Before I get ride of them I would like to see when the table was last accessed for any purpose like any DDL/DML statements and any Select statements performed on the temp/backup tables as well. Is this kind of information readily available in any SYS tables or should I write a trigger to get the details going forward.
for one particular employee, he is having multiple records with the same data in the table
EMPNO ENAME JOB SAL DOB ------------------------------------------------------- 1 A X 100 1956 2 B Y 200 1974 1 A X 100 1956 3 C Z 300 1920
[Code]....
like this am having multiple times the duplicates.
I have written the below query to delete the duplicate records. But it is deleting only one record (if we have 5 duplicates it is deleting only 1 ). But I am looking to delete if we have 5 duplicates need to delete 4 duplicates and keep 1 record in the table.
query which am using to delete the duplicates is
DELETE FROM Table1 a WHERE ROWID IN (SELECT MAX(ROWID) FROM Table2 b WHERE a.ID = b.ID);
it is deleting only one row but I want to delete 4 records out of 5 and keep one record.

I have been using MSaccess to do some updating and deleting of data.I have 2 tables, 1 with data, 1 with the criteria to change, 2 colums (FINDWORD and REPLACEWORD).
The main table has lots of data, and the SQL query im using in access looks like this:
UPDATE TABLE1, tblFindReplaceWords SET CleanList.COLUMN-NAME = Replace([TABLE1].[COLUMN-NAME],[tblFindReplaceWords].[FINDWORD],[tblFindReplaceWords].[REPLACEWORD]);
how would I go about doing the same thing in orcale?
Consider tables A,B,C,D,E,F. all are having 100000++ records Tables B,C,D are dependent on table A (with foreign key constraint). When I am deleting records from all tables, table B,C,D are taking max 30-40 seconds while table A is taking 30-40 mins. All tables are having indexes.
Method I have used:
1. Created Temp table
2. then deleted all records from B,C,D,E,F for all records in temp table for limit of 500.
delete from B where exists (select 1 from temp where b.col1=temp.col1);
3. why it is taking too much time for deleting records in table A.
I'm testing a procedure which loads data into my database, and after each test I want to empty some of the tables and reset the sequences. I have this script to do that...
DELETE FROM COM_MERGE; COMMIT; DELETE FROM COM_TITLE; COMMIT; DELETE FROM COM_ISSUE; COMMIT; DELETE FROM COM_PAGE_ELEMENT; COMMIT; DELETE FROM COM_ELEMENT; COMMIT; DELETE FROM COM_STORY_TITLE; COMMIT; BEGIN COM_RESET_SEQUENCES; END;
Today I added the call to the sequences procedure to my script, but I have been using the script to delete from tables for a number of days without problem.However today I am finding that when I run the script it works ok the first couple of times, but when I try running it for a third time, it hangs after the second delete (in other words it stops when it gets to the delete from COM_ISSUE). After this happened the first couple of times I stopped the db and restarted it, then the script was ok twice, but again I'm finding that the script hangs. There is no error message, but the script fails to complete.
I didn't know if it was because originally I had one commit at the end of the script, so I added commits after each delete but that didn't solve it.I am using SQL Developer but I have found the same problem when running the script from SQL Plus.This is the definition of the COM_ISSUE table (just in case the table is the source of the problem).There is only one row in COM_ISSUE.
CREATE TABLE "BILL"."COM_ISSUE" ( "CI_ID" NUMBER NOT NULL ENABLE, "CI_TITLE" NUMBER NOT NULL ENABLE, "CI_DATE" NUMBER NOT NULL ENABLE, "CI_PRICE" NUMBER NOT NULL ENABLE, "CI_PUBLISHER" NUMBER NOT NULL ENABLE, CONSTRAINT "COM_ISSUE_PK" PRIMARY KEY ("CI_ID") USING INDEX PCTFREE 10 INITRANS 2 MAXTRANS 255 COMPUTE STATISTICS STORAGE(INITIAL 65536 [code]....

As a workaround i'm not deleting the rows, but setting the stored objects to null. At the end of the routine i can truncate the table with the objects since truncating works. I'm not the administrator of the database, therefore i may not change any settings.
Unfortunately i wanted to be able to share Objects between Sessions, which is possible with this workaround (simply don't truncate at the end), but leaves a lot of crap lying around.
How can I delete the duplicate combination of records from the below table.
CREATE TABLE test ( gidNUMBER(10), pidNUMBER(10) ); INSERT INTO test VALUES (10,20); INSERT INTO test VALUES (20,10); INSERT INTO test VALUES (25,46);
[code]....
The condition is if GID = PID and PID = GID then only one combination of these records should be retained. For example Out of 10-20 and 20-10 only one record should be retained.
I have a requirement where i need to retain latest 3 records based on creation date for each customer_id and delete the older records. The customer_ id or contract_number data in the test table are not unique.

I've a primary database and a physical standby.Logs are shipping perfectly from primary to standby.The logs that are applied on the standby are getting stored in a mount point(LINUX-/opt2) which consumes more space(160 GB). Will that be right if I go ahead and delete them?
My rman configurations in primary is:
RMAN> show all;
using target database control file instead of recovery catalog
RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 4; CONFIGURE BACKUP OPTIMIZATION OFF; # default CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default CONFIGURE CONTROLFILE AUTOBACKUP ON;
DELETE FROM sre_t WHERE TO_CHAR(end_dt,'yyyy')<'2000' or TO_CHAR(start_dt)<'yyyy')<'2000';
It's executing for 15 to 20 minutes after that i got the error "session timed out"..The table is having four crore records.The delete statement is deleting 12,00000 records.

Is there any thing that during deleting data from such master table, it is referring to all dependent tables even if dependent data is not present ?
I was importing one schema from Oracle 10g to 11g using traditional import. I imported as a SYS user, so all the objects created in SYS schema. how can I remove these objects and retain only default SYS objects
create table try_x (a number PRIMARY KEY, b NUMBER, c NUMBER, f_text VARCHAR2(10));
insert ALL into try_x values (0,1,1,'abc') into try_x values (1,1,1,'abc') into try_x values (2,1,1,'xyz') into try_x values (3,1,2,'abc') into try_x values (4,1,2,'abc') into try_x values (5,1,2,'abc') into try_x values (6,1,3,'abc') into try_x values (7,1,3,'abc1') into try_x values (8,1,3,'abc2') into try_x values (9,1,3,'abc2') select * from DUAL;
Although a is the PK, records with similar b,c,f_text are considered redundant and I need to delete all occurrences in the table where b, c, d are redundant and leave the unique ones. So I need the result to look like:
a b c f_text ----------------- 0 1 1 abc 2 1 1 xyz 3 1 2 abc 6 1 3 abc 7 1 3 abc1 8 1 3 abc2
I have Oracle 10gR2 database on a windows server, I have scheduled rman backup for this database from Solaris server
set echo onrun { crosscheck archivelog all; backup check logical database plus archivelog; delete noprompt obsolete device type DISK; } exit;
It is deleting the obsolete backup pieces but it is not deleting old archive logs (obsolete archive logs) and it is not even showing old archives as obsolete when I check thru report obsolete
