We want to find out difference of data for some tables between current day & previous day. We can use query with minus operation but it will take lot of time since table size is in range from 200 to 500 GB. We have to do this exercise every day.
i have a employee table .i want to find out duplicate name from this table.so i write following query
select empname from employee having count(empname) >1 group by empname
i find the result but problem is how i can find out the same name if it have any space like ramkumar ram kumar both are same but above query did not.give this data. how i can solve it
I have two identical tables with same structure and have some duplicates between those two. Finally I want to combine togather and in a single table and knockout the duplicates.
SQL how can we do this in a simple way? each tables has around millions records.
Is it possible to find the locked objects in hierarchical order. Consider the below example
--Connect to scott schema create table block_session(a NUMBER, b VARCHAR2(100)) / insert into block_session select rownum,rownum*10 from dual connect by level<=10 / COMMIT / GRANT ALL ON block_session to HR / update scott.block_session SET a=10 where b=10 [code]......
Is it possible to get all locked table details in hierarchical order?
i am using oracle 10g. is there a way to find out the over fragmented tables/indexes ,so that reorganizing or rebuilding them will improve sql performajnce?
I have two tables A with columns a.key, a.location_code, a.status and a.first_name and table B with cols b.key, b.location_code, b.status and b.first_name.
I want to find the missing records between the two tables and as well check whether each column is populated correctly. That is if u take a record with id 1 check if loc_code is same in both the tables and if they are different, insert the key and first record column and second record column into a new table. And similarly if there is no record wiht that particular id in the second table, insert the record.
For missing records in the sense for records which are present in A but not in B, am using
Select a.key_no, a.loc_code, b.loc_code from A,B where a.key_no=b.key_no(+) and b.key_no IS NULL
But the problem is I need to put some constraints on the B table like b.status='Married'and b.loc_code='CA'. When am using this condition in the above query, it's throwing me error saying cannot use outer join operator in and or or.And I could not figure out how to check for the columns being populated correctly between the two tables and at the same time check for missing ones
I have to cleanup data from our tables (Production Environment) that contain millions of rows. The question is apart from the solution of the partitioned tables what alternative recommended solution suggests Oracle?
To delete these tables by using a cursor PL/SQL block or to import all the database and in the tables that we want to remove the old rows to use the QUERY option of the data pump utility.
I have used both ways and i have to admit that datapump solution is much much faster than the deletion that suffers from I/O disk.The question again is which method from these two is more reliable and less risky for the health of the database.
I came across an implementation where data from DB2 tables are moved to Oracle tables, for BI solutioning, using some oracle procedures called from MS SQL DTS packages which are scheduled jobs.Just being curious, can this be done using OWB or ODI rather than the above detour. I suppose there are some changes being done in those procedures before the data is being loaded into Oracle tables, can't this be done using OWB/ODI? Can it be scheduled too as jobs using OWB/ODI?
I would like to be able to sort through a schema's tables to find if particular vendor numbers exist. The decode cross tab works fine, except that it needs static data for each table. How can I code a PL/SQL to populate the table_name and give a count for each row? See example below:
col table_name format a15 set numwidth 10 set lines 1000 set pages 50
select b1.table_name, count(case when a.vendor='86444' then 1 else null end) "86444", count(case when a.vendor='86445' then 1 else null end) "86445", count(case when a.vendor='86469' then 1 else null end) "86469", count(case when a.vendor='86470' then 1 else null end) "86470", [code]........
select profilename from PROFILE where user_data like '%DATE_RULE!115%';
Output will be "Test A".Now, this is just a single value from RULES table used to find the data of PROFILE table.I will have to run the query on multiple values of RULES tables to find records containing a string format of sort "DATE_RULE!<rule_no>". How to search on WILD CARDs like these?
how to display the data which is shown below without duplicate records in compid and compname and all policy_id's should be there while excuting this query iam getting this data.

I wonder if there is some tiny technique to trace a duplicity on a block label without committing the records ( Maybe on Validate or new record instance)
I have one procedure to check duplicate but what I remember that there is something very smart provided from oracle to do that.
We are planning to create physical standby database for 4-node RAC primary to a 4-node RAC standby using Active database duplicate with ASM and OMF
1. while using active database duplicate, do we need to set cluster_database=FALSE in spfile clause and create standby,next change it back to TRUE at standby. Or we don't need to touch it. And also do we need to include instance_number parameter 2. We are using OMF, can we use log_file_name_convert parameter in spfile clause of duplicate. Documentation says log_file_name_convert cannot be used if standby is going to have OMF. Because we have 5 groups for each thread, which are on 5 different disk groups. When standby is created all the logs are created in only one disk group pointed by db_create_online_file_dest_1. 3. To enable force logging at primary do we need to shutdown the database?
I'm trying to add edmx file in my project for first time. I want to choose the oracle provider ODP.net but cannot find Oracle in the data source list. I have oracle 11g installed , odp and odt installed and can access it from the solution as well. I saw the Oracle listed under data source when I tried to connect the solution to the database through server explorer. The solution is connected to Oracle database through ODP.
i have setup the OEM-Dataguard in order to duplicate the DB instance from the primary to the standby DB in the standby server.At first I installed oracle server in Server A (Primary) created DB instance of SCT, in archivelog mode and then I install the oracle binary in Server B (standby) and made 2 servers ORACLE_HOME the same and also I installed OEM agents on the 2 servers and registered successfully to the OEM server.
I then used the dataguard to do the initial backup of the DB in server A and but when I specify the standby DB location, it prompt me the following error.
Error
Examine and correct the following error(s), then retry the operation. Remote Operation Error - Internal error occured
