SQL & PL/SQL :: Compare Two Tables Having Same Structure In Two Different Servers
Jun 4, 2012
I am working in a reporting project.We have different environments.After migration of data base script from one server to another we always need to crosscheck whether newly added columns have been properly migrated or not.
any database script to address the same thing. Last but not the least we have servers with TNS entries. how we can connect to different server while present in one specific server.
1) Sal_master structure is voc_no varchar2(7),voc_date date
2) sal_detail structure is voc_no varchar2(7),item_code varchar2(10),quantity number(10,2)
3). delivery_master structure is voc_no varchar2(7),voc_date date;
4) delivery_detail structure is voc_no varchar2(7),item_code varchar2(10),quantity number(10,2)
I want to compare these four tables i have insert 10 rows in sal_master and sal_detail tables and 5 transaction in delivery tables how to compares 10 records of sal_master,detail with delivery_master and detail if not exist in delivery_master and detail tables then display only sal_master,detail records for example
Voc_no Sale Qty Deliver Qty Remaining Qty
S000075 10 5 5 if data not found from delivery master and detail then answer must be S000075 10 0 10
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';
i wanted to compare a date in one of my tables to sysdate. I have a table reservation and a field in it is Date Reserved From, i wanted to compare this to sysdate and returned the results
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?
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:
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.)
only these two packages in my server. should i have to install oracleasmlib??
[root@RAC1 ~]# /etc/init.d/oracleasm configure Configuring the Oracle ASM library driver.
This will configure the on-boot properties of the Oracle ASM librarydriver. The following questions will determine whether the driver isloaded on boot and what permissions it will have. The current valueswill be shown in brackets ('[]'). Hitting <ENTER> without typing an answer will keep that current value. Ctrl-C will abort.
Default user to own the driver interface []: oracle Default group to own the driver interface []: dba Start Oracle ASM library driver on boot (y/n) [n]: y Fix permissions of Oracle ASM disks on boot (y/n) [y]: y Writing Oracle ASM library driver configuration: [ OK ] [B]Loading module "oracleasm": Unable to load module "oracleasm" [FAILED][/B]
I don't have this package in my installation cd, when i searched in the web i could not find
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?
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:
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:
I have oracle grid control 10.2, I want to get the list of databases and servers that was configured within the Grid, is there any query that I can use to get it from Grid database?
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

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) ;
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.
Due to some some Network issues . we have planing to move oracle database one domain to another domain changing domain name and IP address of oracle database . if want to change oracle database 10g(10.2.0.5.0) 32 bit windows version what are setting s to change in oracle database.
--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.
How to take table structure in oracle? Actually I got it through this command "SELECT dbms_metadata.get_ddl(a.object_type,a.object_name) FROM user_objects a where object_type != 'PACKAGE BODY'"
any other way to get it? I need like table name field name datatype
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?
