am trying to write a simple sql which would delete data from last n months but it will keep the data for the first of each of those month from current sysdate
e.g
Jan 1 - 30 deletes 2 - 30 keeps data for 1st
Feb 1 - 28 deletes 2 - 28 keeps data for 1st
Mar
Apr Current sysdate

Can I achieve the merge (update-only) and delete in a single SQL statement?
merge into table_4
using
(select table_3.col1 col1,table_3.col2 col2,
from table_1, table_2, table_3
where
[code].....
delete from table_3 where <records identified in the 'using' clause of above merge>;
i.e.
delete from table_3
where (table_3.col1,table_3.col2)
in ( select table_3.col1,table_3.col2,
from table_1, table_2, table_3
where
join conditions.....
other conditions ....
group by table_3.col1, col1,table_3.col2
having count(*) >1 );
What I want is roughly as following :
WITH mywith as ( select table_3.col1,table_3.col2,
from table_1, table_2, table_3
where
join conditions.....
other conditions ....
group by table_3.col1, col1,table_3.col2
having count(*) >1 )
update table_4 set col3='N' where table_4.col1=mywith.col1 and table_4.col2=mywith.col2
delete from table_3 where table_3.col1=mywith.col1 and table_3.col2=mywith.col2;
write a query to delete similar records in particular fields(columns) in different tables.

I have created simple data block by wizard and taken tabular layout 10 rows and 6 columns
i want to generate serial number on first column .....
what need to use..?
I have a table with columns job_id, jan, feb, mar ... , and year
I need to create a select query that will get the data from 18 months ago based on sysdate.
So something like:
Select to_char(add_months(sysdate, -18),'MON') from table1 where job_id = 56947 and year = to_char(add_months(sysdate, -18),'YYYY');
However I need the result of to_char(add_months(sysdate, -18),'MON') to actually act as a column name, not a string result.
In my production Db, I have 3 mount points like /vol1/orcl,/vol2/orcl,/vol3/orcl which contains the datafiles.
I have to create a standby like the same location. how to write the db_file_name_convert parameter?
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 read that chunked transfer encoding will work. But I couldn't find out how this is done.
I am writing following query
SELECT DISTINCT a.list_type_code, a.list_type_name
FROM jls_list_type a, jls_list_control b
WHERE b.jalsa_srl = :jalsa_srl
AND b.list_no != a.list_type_code
ORDER BY list_type_code
I just want to display only those records from JLS_LIST_TYPE which is not present in other table JLS_LIST_CONTROL ... for this i wrote above query but it is not working.
So we need an mechanism to read data from LONG RAW and convert into actual file.

Is it possible to create trigger on the various tables and views exists (i.e. dynamic performance views) in data dictionary, when ever any DML operations performs by Oracle it self?

I want to delete data from say 100 tables without disable the constraints.
Tables having foreign key.. which is giving error if I select table randomly to delete.
I want to know the query which will give me the sequence of all tables based upon dependencies, so that If i delete the data on that sequence, it wont give me child record exists error.
I have a table with around 650,000,000 rows and we need to delete about 60,000,000 rows at the end every month and same amount of rows accumulate throughout the month. The deletion usually takes overnight to delete. We are using 10r2 in IBM AIX. The procedure we are using to delete is:
declare
ln_count number:=0;
begin
for i in (select rowid from table1 where some_id<2012090000)
loop
delete from table1
[code]...
When this procedure is started I mostly see that the session is busy in user i/o wait for db sequencial file read. Will using cursor instead will give better results.
I need to create a stored procedure in Oracle 9i which will automatically delete data one by one from a particular table and then by means of same procedure insert record one by one in same table.

I haved drop a datafile on Primary,and the archived log has transported to Standby,but the datafile is still exist in Standby.
Primary
alter tablespace tps_hxl
drop datafile '/u02/app/oracl/oradata/hxl10.dbf';
We are planning to setup a data guard (Maximum performance configuration ) between two Oracle 9i databases on two different servers.
The archive logs on the primary servers are deleted via a RMAN job bases on a policy , just wondering how I should delete the archive logs that are shipped to the standby.
Is putting a cron job on the standby to delete archive logs that are say 2 days old the proper approach or is there a built in data guard option that would some how allow archive logs that are no longer needed or are two days old deleted automatically.

based on the above result set , for a particular group ,only that op will be retained which comes out in the query . say for example , we have got 1,2,3,'D' for group 1,2,3
now since we have got the D Operation from the above query , i don't need the other two rows .i.e.
(1,2,3,'I');
(1,2,3,'U');
what is the best way to delete the data we don't want retaining the rows we want ,using a single sql statement . Also , for the result set row 7,7,7,T I first need to delete the group containing T operation, and insert two new rows .i.e. 7,7,7,D and 7,7,7,I .

I've just started with the Oracle SQL and come from a heavy MS SQL background and I understand that here are some natural differences in the syntax but I'm stumped as to why the following sql represents a problem:
update MASTERMICODES t1
set t1.TEMPTA = ( select t2.TAFCODE
from TA_FEATURES t2
where t2.FCODE = t1.FCODE
)
It returns Error report:
SQL Error: ORA-01427: single-row subquery returns more than one row
01427. 00000 - "single-row subquery returns more than one row"
*Cause:
*Action:
I want it to return more than one row...in fact I want it to make on all rows that have the same fcode between tables.
using the sql statement in SQL server. I noticed some of the sql syntax are different. My sql statement is as below;
---Select fieldA, Sum(fieldB+fieldC) as fieldD, fieldE, fieldF from TableA group by fieldA, fieldE, fieldF ---
the output will be as below;
fieldA fieldD fieldE fieldF
------ ------------- ------ ------
fieldA fieldB+fieldC fieldE fieldF
However, I need to have the total of no of records displayed for the sql statement and I need it in one sql statement with the one above so that I can display the total no of records along with the information for each field.
