View 4 Replies View RelatedI 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?
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

I want to know how to restrict a user(Schema) from deleting the values from a table created in the same schema.
Below is the example.
I have created a table employee in abc schema which has two values.
EMPLOYEE
ABC
XYZ
In the above scenario the abc user can only fire select query on the EMPLOYEE table.
SELECT * FROM EMPLOYEE;
He should not be able to use any other DML commands on that table. If he uses then Insufficient privileges error should be thrown.

i have a tablespace with a datafile of 20g. now by mistake i delete the datafile and then try to delete the tablespace from EM but i got an error which says that data file is not present to delete
Now initially after deleting the file physically so then i check space by applying df -ah at os lvl so it didn't reclaim the space now i try to delete the tablespace from em so it gives me the above error. This might be due to tablespace existence. so how can i reclaim the space.
INSERT /*+ APPEND */
INTO sales_fact
SELECT *
FROM customer_sales_fact_staging
ORDER BY time_wh_id;
COMMIT;
[URL]
Suppose in the above case
SELECT *
FROM customer_sales_fact_staging
ORDER BY time_wh_id;
returns a huge number say more than 10 million or 50 million
will the commit work(one single transaction)
I have a table which has plenty of rows. In production, I would estimate it to be from 30 millions to 300 millions. I need to update on column (flag) in all the rows (created before certain date).Now saying just:
UPDATE MyTable SET flag = 3 WHERE created < to_date('2010-10-08 23:59:59', 'YY-MM-DD HH24:MI:SS');
COMMIT;
Does not seem like a good idea - the commit-buffer would become too big.I will write a PL/SQL script for this. The question is, whether I should:
a) Update each row separately, and commit after every 10000 rows. ( WHERE RowId = [rowId] )
b) Update 10000 rows with set of dates ( WHERE rowId > [some_row_id] AND RowId < [some_row_id_2]
In the latter example the some_row_ids would naturally be fetched. The rowIds come from sequence. So which one would be more effective?I am not too familiar with PL/SQL or Oracle for that matter.

I am having a requirement like below,
Scene 1:
If duplicate records found for SSN,BWE with SAME DATE_CREATED than take the record with HIGHEST DATE_MODIFIED.
Table Structure:

Output needed:
SSN BWE DATE_CREATE DATE_MODIFIED
123 01-JAN-2008 02-JAN-2009 03-JAN-2014
Scene 2:
If duplicate records found for SSN,BWE with different DATE_CREATED than take the record with HIGHEST DATE_CREATED.
Table Structure:
SSN BWE DATE_CREATE DATE_MODIFIED
123 01-JAN-2008 02-JAN-2009 03-JAN-2014

I have a table which has a trigger defined as such on the Main table.
before INSERT OR UPDATE OF USER_NM,COmpany_ID,UPDATED_BY_USER
OR DELETE ON MAIN TABLE OLD AS OLD NEW AS NEW
FOR EACH ROW
When I insert the 1st row (by user Scott)
MAIN TABLE
USER_NM CompnyID UPDATED_BY_USER
----------------------------------------------------------------
ABC1Scott
In the audit table I have this information:
USER_NM CompnyID UPDATED_BY_USER OPERATION_PERFORMED
----------------------------------------------------------------
ABC 1 ScottInsert
When an ADMIN user (other than Scott deletes the above row)
MAIN TABLE:
USER_NM CompnyID UPDATED_BY_USER
----------------------------------------------------------------row deleted....
In the audit table i have 2nd entry as:
USER_NM CompnyID UPDATED_BY_USER OPERATION_PERFORMED
----------------------------------------------------------------
ABC 1 ScottInsert
ABC 1 ScottDELETE
Here the updated_by_user is Scott and not ADMIN, even though I am doing the following in the trigger.
UPDATED_BY_USER := sys_context('USERENV','OS_USER')
I want to show the user who has deleted the record which should be ADMIN.
Since the user deleting may not be the samae as the one who inserted.Any clue?
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.
View 10 Replies View Relatedlooking 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.

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.

*Cause:
*Action:
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 used 'delete input' to delete all the archives backed up.

Although archive in dest1 is getting deleted I am unable to delete those in dest2. how to delete archives in dest2 too.
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;

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.

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.
