Update AGENTS Table With Data Based On Queries?
Feb 3, 2009I 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;

PL/SQL :: Update Vs Merge - Updating One Table Based On Values In Another
Jun 26, 2013I 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?
PL/SQL :: Update Table Based On The Value Of Another Table
Apr 21, 2013Using 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??

SQL & PL/SQL :: Oracle 10g - Update Records In Target Table Based On Records Coming In From Source
Jun 1, 2010I 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,

SQL & PL/SQL :: Update Query Based On Join Condition
Jun 16, 2011I have two tables. By joining these two tables, I need to update a field in table1.
UPDATE table1
SET table1.FLAG = 'Fixed'
where table2.lastname = table1.lastname
and table2.status in ('fulltime','parttime')
I keep getting error 'table1.lastname' is invalid identifier.
I can't understand the error message. I made sure that the fields exist.
SQL & PL/SQL :: Trigger To Update Table1 Based On Condition Of Values In Table2
Feb 20, 2012I 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]....
Forms :: Insert And Update Directly Into Table From Pre Update Trigger Of Block?
May 14, 2010 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?

SQL & PL/SQL :: Create Trigger That Will Update Table When There Is Insert / Update
May 29, 2012i 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);

Jul 30, 2012I stumbled about some weird 11gR2 behavior (running on AIX).When I performed a join between a table with user based content (parts belonging to an sourcing scope) and a base table (parts available) whereas the parts have to fulfill a special regular expression, it showed that the same query is faster when using outer join than inner join (about 0.7sec vs. 20sec; which makes me believe that regexp_like works wrong when involved in an inner join).
i tried the same statement with a standard like (but not fulfilling the same condition).This time performance was as expected (inner join outperforming outer join).

I can see it, the execution plan for the "inner join" doesn't show so much more costs than the one for the outer (but why at all is does an inner join cost more?) ...The execution plan for both "not like" is the same and (surprisingly ;-) ) similar to "outer-regexp".
I hope sample data are not needed as there would be needed a lot...this is the second time I came across the "plan worse but execution time better" phenomenon.

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;
create materialized view log on my_view;
