I have to compare 2 tables on a columns's value.The 2 tables have same column as Regn_no.I just need to have the result in True Or False from a Query if the particular value of Regn_no is found in both the tables.
Temporarily I using a bit different and not good query which is as follows:
select count(*) from tab1 where regn_no in (select regn_no from tab2) and regn_no = 'UP78AN7890';

My tables looks like this:
Desc Table A (account)
Account1_id
Account2_id
name,
empid
Table B (Bill )
BillNo
Advertiserid
agencyid
total vvalue
I need to pick up total value from table B where the unique combination of advertiser-Agency id is the same as the given account1_id -Account2_id combination in table A for each employee id.
In other words my output should be like
Empid | Account_id (should be same as advertiserid)| Account2_id (same as agencyid) | sum(total_value) for this adv-agency combination.....
objective: Get the total value from table B for each unique account1-account2 combination (advertiser-agency in other words) .
I am not sure if I should use a correlated subquery or how to handle the situation....Right now I am just checking the two columns separately like this:
select.......from a,b
where b.advertiser_id = a.account1_id and b.agencyid = b.account2id
Is it correct to do so? I have a feeling that I am missing something if I join them separately like this.

I need to alter a table to check that the data in a column is contained in a similar column in another table.
I have a STORES table and a STORE_REP table. Both tables have a column REP_ID.
I need to add a CHECK constraint into the STORES table to make sure that the info entered into its REP_ID column matches an entry in the STORE_REP table.
Both have a NUMBER(5) data type.
Will it make any difference if the REP_ID column in the STORE_REP table was originally created with a VARCHAR2(5) data type and was later converted to NUMBER(5), while the REP_ID column in the STORES table was created as NUMBER(5) when that table was created?

I want to compare two tables , and delete the common rows from the first table
Here is what i have done :
Create table test1(Test1C1 Number,
Test1C2 varchar2(50));
Create table test2(Test2C1 Number,
Test2C2 varchar2(50));
Insert into test1 values(1,'testdata1');
Insert into test1 values(2,'testdata2');
Insert into test1 values(3,'testdata3');
[code].......
it deletes all the records from Table test1. What should I modify here ? or should I write a different query ?

We have eight servers. One of them is for centeral management. The other seven is for development and test databases. Every night, we start a process which exports database schemas (without data) into the centeral server. An example of the process we run is just like below:
CODEcd /data1/backup
mknod exp_pipe_oracle1 p
compress<exp_pipe_oracle1>dev.dmp.Z&
exp user/****@dev file=exp_pipe_oracle1 owner=schema1,schema2,schema3 statistics=none rows=n log=dev.log
As you can see, we use @dev to connect remote database. But dump file is created in local (centeral) server. We are planning to use datapump instead of classic export in future. But I couldn't find a solution, that could take a database export in a remote server and create dump file in local. I have looked at NETWORK_LINK parameter; but it doesn't seem to work for our case.
Is it possible to backup a remote database with datapump and make it create dumpfile in local? (Of course we can use some solutions such as NFS, but we really not prefer this; if datapump has ability to remotly backup.)

Is the 12c version of the Grid Control only for Oracle Cloud? Not completely sure of exactly what cloud computing is. Looks like a conglomeration of shared resources. Anyway we are converting all of our servers over to vmware virtual machines except the ones we manage in other states. I am upgrading each database to 11 r2 as we convert the servers. Anyway my Grid server is next to convert to a virtual machine. I am using Grid Control 10.2.0.5.0 now. I want to upgrade to the latest version of the Grid control. 12c seems to stress and boast about managing the "Oracle Cloud" to manage regular single node Oracle servers as well as vmware virtual machines?

I wanted to practice dataguard in oracle. I feel that I can practice realistically if I have 2 different servers to do switchovers, building new physical standby database from scratch and shipping the archiving logs from primary to physical standby database, etc., Can I use VMWare software to install 2 different servers and then practice dataguard?

How do I get a list of all servers associated with linked databases?
for example: I have an entry in TNSNAMES.ora:
PTSYS =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = BMSQL2.BEAM.LOCAL)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = PTSYS)
)
)
if I link this database as follows:
create public database link SourceDB --@PTSYS
CONNECT TO sysadm IDENTIFIED BY password
using
'PTSYS';
How can I tell that this database is on the BMSQL2 server?

I have a two node RAC on 11.2.0.3. We are using SCAN Listener here. On my node 1, i can connect to the database using tns alias: The alias looks something like:
Prod =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = x1200.prod.com)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = cusms)
(UR = A)
)
)
sqlplus system/actdbasystem@cusms ----- works sucesfully on the prod server. Even the same prod alias copied to second tnsnames.ora in the cluster and run, it works sucesful too. But the issue is, when we copy the same alias onto any other servers and try to connect give's the following error message:
SQL*Plus: Release 11.2.0.3.0 Production on Fri Jul 27 12:37:55 2012
Copyright © 1982, 2011, Oracle. All rights reserved.
ERROR:
ORA-12519: TNS:no appropriate service handler found
[code]...
why is it my connection using sqlplus works locally and not from other servers?

I know how to create a database link between two oracle servers, but problem is that SID is same for both servers, Is there any other way to connect two servers without using only 'SID' ..here are TNSNAMES.ORA FILE i HAVE
D.w=
(DESCRIPTION=
(ADDRESS=
(PROTOCOL = TCP)
(HOST=ff.ffc.pic.com)
(PORT = 1521)
[code].......
Is there any other way rather that this
Create database link a connect to username identified by password using 'SID';
Any alternative like using SID.A.w or how I can differentiate these two SID s.

We are facing space crunch in our 4 development 11i ERP environment servers and decided to reclaim the space . We are having 11.1.0.7 Database . What we observed is, there are many objects present in the recyclebin and we went on to purge the reclybin of MSC user.
SQL>select owner,sum(space)* 8 / 1024/1024 "Size in GB" from dba_recyclebin group by owner order by sum(space) ;
OWNER Size in GB
--------------- ----------
MSC 127.672485
IRCUS 22.5664063
GL 2.98492432
APPS .38079834
XXDII_ESB .192993164
APPLSYS .001159668
TMPBKP .000427246
But even after purging the recycle bin of MSC User , we didn't find any changes in DBA_FREE_SPACE for those tablespaces in which recyclebin objects were present. We would have seen the freed space in dba_free_space.

Our application servers will be running a SELECT which returns zero rows all the time.This SELECT is put into a package and this package will be called by application servers very frequently which is causing unnecessary CPU.
Original query and plan
SQL> SELECT SEGMENT_JOB_ID, SEGMENT_SET_JOB_ID, SEGMENT_ID, TARGET_VERSION
FROM AIMUSER.SEGMENT_JOBS
WHERE SEGMENT_JOB_ID NOT IN
(SELECT SEGMENT_JOB_ID
FROM AIMUSER.SEGMENT_JOBS) 2 3 4 5 ;
[code]....
Which option will be better or do we have other options?They need to pass the column's with zero rows to a ref cursor.

--this for txn details
CREATE TABLE txn_det(
txnid NUMBER PRIMARY KEY,
amount NUMBER,
status varchar2(50),
cust_id NUMBER);
----this for customer details
CREATE TABLE cust_det(
cust_id NUMBER PRIMARY KEY,
cust_name VARCHAR2(50),
cust_acc number(15));
--data to insert for customer table
INSERT INTO cust_det VALUES(101,'Miller','12345');
INSERT INTO cust_det VALUES(201,'Scott','45678');
----data to insert for txn table
INSERT INTO txn_det VALUES('tx0045',123.00,'success',101);
INSERT INTO txn_det VALUES('tx0046',4512.50,'success',101);
insert into txn_det values('tx0049',78.12,'success',101);
INSERT INTO txn_det VALUES('tx0055',123.12,'success',201);
Now THE problem IS cust_det TABLE's cust_id coulmn may contain duplicate.So I thought OF adding THE txn_id COLUMN TO THE cust_det table but I know that encourgaes redundancy.

I have a hierarchy tree i query using connect by. The primary key is the up level to other parts. I need to copy the entire tree structure as a new structure.
This will mean renaming the IDs to new unique ID yet keeping the up levels correct.
i.e.
ID DESC UPLEVEL
1 TOP
2 desc2 1
3 desc3 1
4 desc4 3
5 desc5 4
6 desc6 1so if i coped this i would expect
7 TOP
8 desc2 7
9 desc3 7
10 desc4 9
11 desc5 10
12 desc6 7

We are trying eliminate/minimize the downtime for our application. As part of new code deployments sometimes we need to modify DB Structure also. As it is taking time to backup current DB and apply new DDL, the application is down.
Is there a way to eliminate the downtime, if I can leverage Data Guard, Golden Gate or RAC concepts?
