SQL & PL/SQL :: How To Update Data From Backup Table
Nov 4, 2013
I have a table named employee with 10 records. Empid is the primary key and empsal contains salary of the employees. I created backup of this table and name of backup table is empbackup.
Now empsal was updated to empsal*10 in employee table and 10 more records were also inserted in employee table. Now I want to restore the empsal column for 10 employees from empbackup(as initially there were only 10 employees in employee table when empbackup was created) table how can I do that in PL/SQL or Oracle?

How can we update nested table based on index number
I am trying to develop a form consisting of a key block and a single data block. The problem is that the driving table is not the table that needs to be updated.
user wants the following layout:student Advisor ID# name degree major Concentration ID# name The driving table (TABLE A) will supply the first 5 fields. The advisor ID comes from (TABLE B).
The user needs to update the adviser ID# field associated with the student ID# field. The form is to be tabular listing all students. I've seen some info on using procedures to insert, delete, update, query and lock tables, but i'm just not sure if that's what is needed.

How to write an sql queries to update lastyear and currentyear columns with sum of quantities based on itemnum and location in Inventory table
I was trying to update the AGENTS table with the data based on queries. But all the records updates with the same data. I can't understand why.
Write a PL script to populate these columns as follows:
TRAVEL_STATUS is one of three values: GLOBETROTTER: agent has visited five or more different locations in the course of his missions ROVER: agent has visited between one and four locations SLOB: agent has been on no missions.
CONTACTS is the number of targets that share the agent's home location.
some of the tables and columns are agents table: agent_id, location_id targets table: target_id, location_id missions_agents table: agent_id, mission_id missions_targets: target_id, mission_id missions table: mission_id, location_id
My code is
DECLARE status AGENTS.TRAVEL_STATUS%TYPE; contact AGENTS.CONTACTS%TYPE; CURSOR loc_cur IS SELECT a.AGENT_ID id,
I've to do a update activity for data correction. There are about 1 crore records involved in this. I want to keep a log of the activity at least Sales No. so that I can validate my data correction. Main cursor is involved for this. The problem is if I insert each record for sales number in the loop then process will take about double time. So i decided to create a nested table and insert after each session finishes.
I'm talking about session here is. The table I'm updation is partition table. So I can have many sessions and each session updating different table partition. This way there is no lock, better performance. Server has 35 processors so I can at least have 25 sessiions.
I could have used varray for this. But I want to learn nested table also. Problem here is not to take different way to complete this activity but to learn why I'm facing this issue.
CREATE OR REPLACE TYPE OBJ_TXN_LOG AS OBJECT ( SALES_NO VARCHAR2(24) ,sALES_SEQ NUMBER(4) ) ;
Yesterday my colleague noticed that, the complete data (1 year) got missed out from a table and the data is available only from last friday.
And then we restroed the data from the backup.
Now we have been asked to find out who has deleted or truncated the data? But in the database, audit is enabled only to log sys operations. So is there any way to find who ran the delete or truncate command on this DCA_CLA_BATCH table on friday?
SQL> show parameter audit
NAME TYPE VALUE ------------------------------------ -------------------------------- ------------------------------ audit_file_dest string /dborafiles/edcap/edcapd/adump audit_sys_operations boolean TRUE audit_syslog_level string audit_trail string OS
Our client has this scenario:May 23th 4:00 PM a user truncate a critical table. The customer need to recover the data before truncate.
The recover materials list like this: 1. A cold backup of this database at May 1th. 2. The archive log except May 1th ~ May 15th. 3. Every day exp at 00:30 and 12:00.
Is there any way to recover the data before truncate table with these material?
I have a base table (Table A) block with multiple records displayed. I need to track audits to this underlying table in the following way:
If user updates a field in the block I want the pre-changed record's audit fields to be set and I need to create a copy of the record with the changed values. Basically any changes will result in the record being logically deleted, and a copy record created with the newly changed values.
Tried to implement in the block's pre-update trigger which will call a package to directly update Table A then Insert into Table A, then requery the block. Is there a clean and efficient way to do this?
i want to create a trigger that will update a table when there is an insert or update.i can't across this error that i don't even know what it means "table %s.%s is mutating, trigger/function may not see it".
*Cause: A trigger (or a user defined plsql function that is referenced in this statement) attempted to look at (or modify) a table that was in the middle of being modified by the statement which fired it.
*Action: Rewrite the trigger (or function) so it does not read that table.
CREATE OR REPLACE TRIGGER set_date_end BEFORE INSERT OR UPDATE OF issued ON shares_amount FOR EACH ROW DECLARE BEGIN INSERT INTO shares_amount(date_end) VALUES(SYSDATE); END set_date_end; /
I have a column "empno" in EMP table and "deptno" in DEPT table . I want to update both the columns with single UPDATE statement. With out a creation of stored procedure or view(updating it through view).
I have an oracle autoback of controlfile and spfile. I am trying to restore the production database using this backup, into a new server with a different directory structure.
I have completed the following steps in the restore process.
1. Creating a pfile from spfile

3. Then creating a spfile from this pfile
I am stuck on the next step where to rename all the datafiles and tempfile and restore the database. Following is what I did.
After mounting the database in RMAN, tried to run the following.

I am not able to take backup of table which is partitioned.Whenever i start the backup it was hanging with wait event "asynch descriptor resize", so I tried to create another table using original table ( like create table BASE_TABLE AS SELECT * FROM BASE_TABLE), but it is also hanging with same wait event.
creating an sql script that can update info from one table in dbase1 to another table in dbase2 that has the same columns and if possible insert date and time in one column when the synchronized is done?
My scenario is I need to insert into History table when a record is been updated into a tabular form(insert the updated record along with the additional columns Action_by,Action_type(Like Update or delete) and Action Date Into History table i.e History table contains all the records as the main table which is been visible in tabular form along with these additional columns ...Action_by,action_type and action_date.
So now i dont want to create a befor/after update trigger on base table rather i would like to create a generic procedure which will insert the updated record into history table taking the page alias and pade ID as the parameters(GENERIC procedure is nothing but whcih applies to all the tabular forms(Tables) contained int he application ).
I am trying to update columns of Table A with the columns of Table B. Both these tables have 60,000 rows each. I tried this operation using following 2 queries:
Query 1
Update TableA A set (A.col1,A.col2,A.col3)=(select B.col1,B.col2,B.col3 from TableB where A.CODE=B.CODE)
Query 2 Update TableA A set (A.col1,A.col2,A.col3)=(select B.col1,B.col2,B.col3 from TableB where A.CODE=B.CODE) where exists A.code = (select B.code from TableB B where A.code=B.code)
When i execute these two above queries, it keeps executing indefinitely.
I need to take a snapshot of a table before insert or update happens to that table.... in oracle 10g. I am reading the MV docs from oracle and below link..
[URL].......
how MV should be written for this and how to schedule it in dbms_jobs for auto refresh?
assuming that t1 is the table where DML operation are goin to happen so before any insert or update, snapshot has to be taken, and I am assuming that to do this it would look something like this?
create materialized view my_view refresh fast as select * from t1;
i have two databases and created the link between them. I can easily query the data but when i need to update my local records from the remote its showing an error
