I need to update more than 1million records in a table. I am using Oracle Warehouse Builder to do this Job. it is taking more than 3 hours still running. I don't have any Indexes on this table.
View 11 RepliesI am trying to update records in the target table based on the records coming in from source. For instance, if the incoming record is present in the target table I would update them in the target else I would simply insert. I have over one million records in my source while my target has 46 million records. The target table is partitioned based on calendar key. I implement this whole logic using Informatica. Looking at the informatica session log I find that the informatica code is perfectly fine but its in the update part it takes long time (more than 5 days to update one million records). find the TARGET TABLE query and the UPDATE query as below.
TARGET TABLE:
CREATE TABLE OPERATIONS.DENIAL_REGRET_FACT
(
CALENDAR_KEY INTEGER NOT NULL,
DAY_TIME_KEY INTEGER NOT NULL,
SITE_KEY NUMBER NOT NULL,
RESERVATION_AGENT_KEY INTEGER NOT NULL,
LOSS_CODE VARCHAR2(30) NOT NULL,
PROP_ID VARCHAR2(5) NOT NULL,

I'm working with Oracle 10g.
I have a table like this;
ID Amount Date
123 5000 Oct-07-2011
123 null Oct-09-2011
124 7000 Oct-14-2011
124 null Oct-17-2011
124 null Oct-24-2011
What I'm trying to do here is loop thruogh the records and update the amount that's null with the previous amount with the same ID.
CREATE TABLE "SCOTT"."SEATALLOTMENT"
("YEAR" NUMBER(4,0),
"COLLEGECODE" CHAR(4 BYTE),
"COURSECODE" CHAR(3 BYTE),
[Code].....
Now i want to UPDATE reducing the AVAILABLE column by 1 in COURSESEATS table based on common columns collegecode,coursecode for a ROW inserted into SEATALLOTMENT table ,i am confused to what approach i have to follow whether its a procedure or a trigger
CASE:
Here in this case as i insert a row with krcl,cse as college code and course code respectively into seatallotment table the available column in courseseat table for the respective row with mentioned common column must become 59 from 60
i have a table in my PD database which have more than 30,000 records .some records in a column say p_code is not tagged with code like '9876543'while other records are tagged in this column with code such as '19022345678'.
Now i want to update these records with tagging 1902 with each one .
Lets take the basic emp table for our Referenece and lets assume that it contains around 60000 Records and all the deptno in that table are Initially 10. Please provide an update statement which would update deptno column of EMP table((based on) order by EMPNO) in for every 120 records incrementing by 1.(DeptNo to be incremented by 1,like 10 ,11 , 12 etc).
First 120 Records deptno should be 10,
Next 120 Records deptno should be 11, and so on.
.

For Last 120 records deptno should be updated with 500.

I have taken all the records in to a cursor. Once after rounding the request of 1st rank and adjusting the values of next rank is done. Trying to round the value for 2nd rank as done for 1st rank. Its not taking the recently updated value(i,e adjusted value in rounding of 1st rank).
This is because of using a cursor having a value which is of old value. Is there any way to handle such scenario's where cursor records gets dynamically updated when a table record is updated.
I have a table formatted like this
ID|First Name|Second Name
1|X|X
2|X|X

I understand how to do individual updates, I want to know how it is possible for me to do this as one query, as I have several thousand records to update.
I want to update a table 8 million records of a table which has 10 millions records, what could be the best strategy if the table has a BLOB column with 600GB worth of data. BLOB itself is 550GB. I am not updating the BLOB column. Usually with non-BLOB data i have tried doing "CREATE TABLE new_table as select <do the update "here"> from old_table;" method .
View 6 Replies View Related 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?
The requirement is I have a table (TAB1), wherein I have 3 columns, ID, LID and STATUS.
The value in ID column = ID_SEQ.NEXTVAL,and LID will be either 0 or 1 and the possible values for STATUS are 'ED','CP', NULL. The ID column is not suppose to have duplicate values, but there is no check on the table for the same.
Someone has updated the existing data and ID column is containing duplicate values. Wherever LID = 0 and STATUS = NULL and if only if ID is duplicated then the ID_SEQ.NEXTVAL has to be assigned to ID field, so that there are no more duplicate values.
CREATE TABLE tab1 (id NUMBER , lid NUMBER, status VARCHAR2(10));
Existing Data
------------------
INSERT INTO tab1 VALUES (1,0, 'ED');
INSERT INTO tab1 VALUES (1,0, 'CP');
INSERT INTO tab1 VALUES (1,0, NULL);
INSERT INTO tab1 VALUES (1,0, NULL);
INSERT INTO tab1 VALUES (1,0, NULL);
INSERT INTO tab1 VALUES (1,0, NULL);

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.
So I wrote this trigger but its not working
create trigger test_trigger after update on test1 for each row
begin
update test2 set name=new.name where test2.id=id
end

I have a table which is updated with new records in each 15minutes from network. In order to get the accurate information I must do some arithmetic calculations on some variables.
For example, if the value for column A is 10 @9.45AM and 15 for @10AM the real result should be 15-10=5 for 10AM; because the values are cumulative so I need to subtract. Similar to this I have same operations for 9 more attributes in my table as well.
In order to handle this I used view and did necessary operations by using joining table like this (table name is Operations lets say and id is Primary Key)
create view ....
...
from Operations current, Operations prev
where current.datetime(+) = prev.datetime - 1 / 96
and current.id = prev.id
When I use this view, the simple select query takes about 15min since I have 25GB record for this table. What can I use instead of this join and solve cumulative values issue?
I want to update / insert records from one user to other user therefore I write this code in my form but it gives me error.

*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.

Oracle 11gI have a large table of 125 million records - t3_universe. This table never gets updated or altered once loaded, but holds data that we receive from a lead company. I need to select records from this large table that fit certain demographic criteria and insert those into a smaller table - T3_Leads - that will be updated with regard to when the lead is mailed and for other relevant information. select records from this 125 million record table to insert into the smaller table.
I have tried a variety of things - views, materialized views, direct insert into smaller table...I think I am probably missing other approaches. My current attempt has been to create a View using the query that selects the records as shown below. Then use a second query that inserts into T3_Leads from this View V_Market. This is very slow. Can I just use an Insert Into T3_Leads with this query - it did not seem to work with the WITH clause? My Index on the large table is t3_universe_composite and includes zip_code, address_key, household_key.
CREATE VIEW V_Market asWITH got_pairs AS ( SELECT /*+ INDEX_FFS(t3_universe t3_universe_composite) */ l.zip_code, l.zip_plus_4, l.p1_givenname, l.surname, l.address, l.city, l.state, l.household_key, l.hh_type as l_hh_type, l.address_key, l.narrowband_income, l.p1_ms, l.p1_gender, l.p1_exact_age, l.p1_personkey, e.hh_type as filler_data, 1.p1_seq_no, l.p2_seq_no , ROW_NUMBER () OVER ( PARTITION BY l.address_key ORDER BY l.hh_verification_date DESC ) AS r_num FROM t3_universe e JOIN t3_universe l ON l.address_key = e.address_key AND l.zip_code = e.zip_code AND l.p1_gender != e.p1_gender
