trying to update a column in a table which has 3 columns of 16million rows from column in another table which has 1million rows, there is no relationship between the 2 tables.
Table A has 3 columns of 16million rows, the first two columns have 16million ID numbers, the 3rd colunm is currently NULL.
Table B has 1million Numbers, i need to somehow update column 3 in table A using the numbers in table B, it doesnt how many times each of the 1 million numbers are used but i dont want it to just update every row to the same value.
I am facing some challenge while running update query on newly added column in existing table.
Environment Details
Oracle 9i, version 9.2.0.6
Os Unix Aix 6.1
No of records in table : 12572770
Below are the step i followed.
1. In table testtablename, I have added new column COLUMNNAME29 with datatype VARCHAR2(8).
2. After adding the new column, i executed the update query to populate the data form COLUMNNAME1 to COLUMNNAME29.
3. The query is executed using COLUMNNAME24 in where clause, to drive query in index based.

Problem faced & My analysis
1. The update query is hanging in database, it's not progressing (In single update, approximately 40000 records will get update)
2. No oracle error thrown in alert log or in session where the query being executed.
3. The event for the query is "db file sequential read".
4. When i update the newly added column COLUMNNAME29 with static value "1", the update completed successfully in few seconds.
5. Then i changed the static value to "1111" and executed the update statement, which result to query hanging in database.
6. I tried to update the existing column(COLUMNNAME1) in table with static value "1111", the update completed successfully.
Below are the queries completed successfully
Update Testtablename
Set Columnname29 = '1'
Where Columnname24 >= To_Date('01-12-2002 00:00:00', 'DD-MM-YYYY HH24:MI:SS' )

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 have table test1(id,name) and table test2(id,,name)
Now when I update name column of a row on test1 I want the same value to be updated for the same id in test2.

begin
update test2 set name=new.name where test2.id=id
end

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);

update table1 t1 set t1.column1 = t2.column2
from table2 t2 inner join table3 t3 on t3.column3=t2.column4

I tried read up merge and update, but not really understand how the syntax works in oracle.

While updating a table, is it possible to get the old value of a column. I need to get it inside a PLSQL block and not in a trigger.for example :-
DECLARE
l_amountNUMBER(5) := 0;
BEGIN
UPDATECustTransactions
SETamount = 150
WHEREcust_id = 5412
RETURNING amount INTO l_amount;
DBMS_OUTPUT.PUT_LINE ( 'l_amount= ' || l_amount );
END;
By using the RETURNING clause i am getting the new updated value. I need the old value for some processing. Do i have to explicitly query it before the update stmt? Pls reply.
I am having a table with out a primary key .It also contains data.
My requirement is to add a new column to the table and update the column value with unique and sequential number , starting from 1 to end of rows.
This has to be done without using a sequence.
There is a need for me to UPDATE a DATE column from one date to another. So as an example,
we have TABLE A and Table A has a column (DATE_TO) with date field value off
DATE_TO
31-DEC-99
12-APR-15
15-MAR-16
What I want to do is update '31-DEC-99' to '31-MAR-13' and for it to only effect '31-DEC-99' (the others are fine).

View 2 Replies View RelatedDoes "Update on a Partitioned Column" cause fragmentation ?
See example below :
Suppose I have a table as below that has approx 3 million rows and growing :
1) Table ABC :
file_id number
status_flag varchar2(1)
file_Content clob
date_created date
2) This table is list partitioned on Column "status_flag".
Column "status_flag" can take 3 values "A" or "B" or "C"
3) A file_id can transition from 1 "Status_flag" to another. [ A--> B , C--> B, B-->C, A --> C, etc ]
This means its possible to UPDATE the "status_flag " - the partitioned column.
Question :
-------------
1) Would the movement of rows from 1 partition to another cause fragmentation ?
2) Or Instead, should this be achieved by maintaining 3 tables - 1 each for every "status_Flag" as Table_A, Table_B, Table_C
This would mean that, if file_id 1, changes "status_flag" from 'A' to 'B' :
-- The corresponding row from Table_A will be created in Table_B
--- The same will be deleted from Table_A
This would still cause fragmentation ... with the overhead of Inserting a CLOB column from 1 table to another.
3) How to determine how much percent of the table is fragmented ?
my need is to perform merge - update when id column is matched, but one of others columns not.When id column is not matched then I perform insert.
It works fine for matched or not matched id column.
Commented code is my try to perform check for others columns, The code should not update when all columns match. It should update only when on of columns doesn't match (except id column of course, because it's key column).
