Update AGENTS Table With Data Based On Queries?
Feb 3, 2009
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,
[code].....

[Code]....
Table 2: Inventory
ITEMNUM STORELOC lastyear currentyear
AM1324 AM1 need sum(quantity) here need sum(quantity)
AM1324 AM2 need sum(quantity) here need sum(quantity)
We have to update the last year and current year columns with sum of quantities for each item from matusetrans table based on date at different location in Inventory table.
we had nearly 13,000 records(itemnum's with different location) in inventory table in DB we have to update entire records.
How to write an sql queries to update lastyear and currentyear columns with sum of quantities based on itemnum and location in Inventory table

Here is my problem, i need to create some files with my own format(let say 5000 records each) from a huge data table (May contain 5 Million records). And i want this creation to be multi threaded.
so how can i form queries efficiently to fetch records like 1..5000 and 5001..10000 and so on. I can form some thing like select * from table where rownum<5000 and not exists ( already fetched records) . but it is not the efficient one.

I have two tables lets say TAB_A and TAB_B. I altered table B to include a new column from table A I wrote a merge statement as follows to merge the data
MERGE INTO TAB_AUSING TAB_BON (TAB_A.SECURITYPERSONKEY=TAB_B.SECURITYPERSONKEY)WHEN MATCHED THEN UPDATE SET TAB_A.PPYACCOUNT=TAB_B.PPYACCOUNT;
I know INSERT is for inserting new records UPDATE to my knowledge is to modify currently existing records (loosely) MERGE is one I rarely used, until this particular scenario. The code works perfectly fine, but I was wondering how could I write an update statement? Or in this scenario should I even be using an update statement?

Using Oracle 11g SOE R2...
I used to have two tables to store details of PROPERTIES e.g UNIT_COMMERCIAL , UNIT_RESIDENTIAL. I need to combine both of them into one table called UNIT. I moved the data to the new table, but now I am stuck how to update the values of the child table which called MARKETING.
---
Now, I have two tables:
MARKETING (ID NUMBER PK , OLD_UNIT_ID NUMBER FK ...)
UNIT (NEW_ID NUMBER PK , OLD_UNIT_ID NUMBER ... )
I need to update the value of OLD_UNIT_ID in Marketing table to be equal to NEW_ID in the table of UNIT. As you can see the values of OLD_UNIT_ID in both tables are the same.
I used this statement
update ( SELECT distinct M.UNIT_ID , U.OLD_ID , U.ID FROM MARKETING M INNER JOIN UNIT U ON (M.UNIT_ID = U.OLD_ID)) set unit_id = idBut I got this error:
ORA-01732: data manipulation operation not legal on this view??

2> 60 million recs
update mycustomer set update_time=sysdate-seq_num where seq_num <> 1;

I am working on forms 6i. I have one data block based on table EMP.
Datablock-A: Empno, Ename, Sal
I have FIND Screen: Empno, Ename, FIND Button.
I can search the data through FIND Screen and populate data in Datablock A.
I am using below logic to search data through FIND Screen.
When-Button-Pressed(FIND Button): calling 'EXECUTE_QUERY'.
In Pre-query trigger of DatablockA:
copy(:FIND.EMPNO,'BLOCKA.EMPNO');
copy(:FIND.ENAME,'BLOCKA.ENAME');
It's working fine. But below case is failing.
Let us say, if i enter empno 10 (which is not there in database) in FIND Screen --> press FIND Button, it's showing up 'QUERY CAUSED NO RECORDS', Till this point it's working fine;. But after this, if i press CTR+F11 in block A, it's not pulling records. only this case it's not pulling records.
But if i enter something else in FIND Screen, if it returns any data, then if i press CTR+F11,it's pulling all records.
why it's failing to pull records if i try to query data in first case only.

I have two update queries in the same Proc. One Seems to run just fine, the other I am getting this error:
ORA-01427: single-row subquery returns more than one row
The working Updates' structure is the same as the erroneous one. This works:
UPDATE P0525_STOREROOM_HOLDER H
SET H.STRATIFICATION_ID = (SELECT X.STRATIFICATION_ID
FROM EMISTRATIFICATION_XS X
WHERE H.TOA = X.TOA
AND H.STOREROOM = X.STOREROOM
AND H.NSN = X.NSN
AND X.ASSEMBLY = 'NO REQUIREMENT' );
This one gives me a single-row error:
UPDATE P0525_STOREROOM_HOLDER H
SET H.STRATIFICATION_ID = (SELECT X.STRATIFICATION_ID
FROM EMISTRATIFICATION_XS X
WHERE H.TOA = X.TOA
AND H.STOREROOM = X.STOREROOM
AND H.NSN = X.NSN
AND X.ASSEMBLY = 'ABOVE ALLOWANCE'
AND H.NSN_QUANTITY > 0);
I have run a check on the data and there doesn't appear to be any duplicate values in the second update... Both Updates are supposed to be updating record sets not a single row (i.e. the stratification_id where the criteria matches...

I 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 thought this was the easy bit in APEX when you just create a form based on a table, with some validations etc. and use it to insert,update data. However on inserting the first record, I get the following error:
is_internal_error: false
ora_sqlcode: 100
ora_sqlerrm: ORA-01403: no data found
[Code]....
The form is based on a table with a primary key and the primary key is populated from an APEX-generated sequence.
I tried recreating the form, but still no good and now I get the no data error even when clicking "RUN" at page level, so the page does not even display.

I have EM Agent 10g installed in its own Oracle Home (c:oracleagent10g) and Oracle 11g installed in its own Oracle Home (c:oracle11.2.0) The Server shows in EM console but the only target is the EM Agent,.. neither the Listener or the Database show under the targets tab in EM. Also, when DBCA is ran and we get to step 4 it shows NO AGENTS FOUND.
Have installed patch: 8825226 and 8968580 for EM Grid Control (Windows 2003 R2 32Bit) And 9138201 for 10g Agent on Server 2008 R2 (64bit)

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.

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.

I'm using few cursors to update my data and store it back to the same table. But for some reason the cursor seems to be picking obsolete data.
cursor c1
is
select distinct roles
from table1
where flag = '1';
cursor c2
is
select distinct roles
from table1
where flag = '1';
begin
for i in c1
loop
here im updating the roles im picking to to a suffix and role.
update table1
set role = suffix_role
where 'some condition';
end loop;
commit; -- committing so changes are visible for my next cursor.
for j in c2
loop
here im deleting all the roles that are not part of my comparing table.
delete from table1
where role = 'something';
But in my debugging table i see that its deleting roles present as input for first cursor, whereas it should actually pick data with suffix_roles.

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)

I have two tables as
Table LEAVE
Column Type Null Description
APP_NO Number(6,0) Not Null PK Leave Application Number
ECN Number(6,0) Not Null FK Employee Code Number
APP_Date Date Not Null Date of Application
From_Date Date Not Null Date from which the leave starts
TO_Date Date Not Null Date upto which the current application leave remains i.e. end of leave applied for date
NO_OF_Days Number(2,0) Not Null Difference between TO_Date and From_date
LEAVE_TYPE VARCHAR2(3) Not Null Can be one of SL, CL, LWP or LTA
Status VARCHAR2(25) Not Null Can be one of Saved, Rejected or Approved
Remark VARCHAR2(100) Nullable Reason to be put if status is rejected
[code]....
What I really want to do is that when a record is inserted in the LEAVES table (an application for leave is submitted by any employee and if it is approved) then I want to update the _USED values of the corresponding LEAVE_TYPE in the LEAVEENTITLE table which holds values of types of leaves entitled to employee.
For example if 3 rows are inserted in the LEAVES table as
INSERT INTO LEAVES (APP_NO,ECN,FROM_DATE,TO_DATE,APP_DATE,NO_OF_DAYS,LEAVE_TYPE,STATUS,REMARK)
(1,1234,'2012-01-01','2012-01-05','2012- 01-01',5,'SL','APPROVED',null);
INSERT INTO LEAVES (APP_NO,ECN,FROM_DATE,TO_DATE,APP_DATE,NO_OF_DAYS,LEAVE_TYPE,STATUS,REMARK)
(2,1235,'2012-01-01','2012-01-05','2012- 01-01',5,'CL','SAVED',null);
INSERT INTO LEAVES (APP_NO,ECN,FROM_DATE,TO_DATE,APP_DATE,NO_OF_DAYS,LEAVE_TYPE,STATUS,REMARK)
(3,1236,'2012-01-01','2012-01-05','2012- 01-01',5,'LTA','REJECTED','Clash with the annual meet, revise dates');
Then the value of SL_USED in the LEAVEENTITLE table of record corresponding to the ECN = 1234 should be updated with +5 and naturally the SL_ UNUSED value of the record should be updated as SL_ENTITLED - SL_USED. For the APP_NO 2 and 3 none of the values in LEAVEENTITLE should be updated as the STATUS is not 'APPROVED'
I tried with the following trigger, but is compiling with a warning (not showing what the warning is)
CREATE OR REPLACE TRIGGER leaveentitle
AFTER INSERT ON LEAVES
FOR EACH ROW
BEGIN
UPDATE LEAVEENTITLE LVE
SET LVE.SL_USED = SL_USED+(CASE
WHEN :NEW.LEAVE_TYPE = 'SL'&& NEW.STATUS='APPROVED'
THEN :NEW.NO_OF_DAYS
SL_UNUSED=SL_ENTITLED - SL_USED
ELSE 0
END),
[code]....
