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.
My oracle version is oracle 9i
I need to commit after every 2000 records.Currently am using the below statement without using the loop.how to do this?
do i need to use rownum?

a project I'm working on. I normally work in SQL Server, so I'm a little stuck on this one.
I have a temp table (tmp_stack) with four columns:
Floor [varchar]
Unit [varchar]
Block [number]
BlockStart [number]
BlockEnd [number]
BlockStart and BlockEnd are currently NULL. What I need to do is loop through the table for each Floor and update BlockStart and BlockEnd for each Unit depending on how many blocks they use and how many have been used by prior units on that floor.
For example:
There are three units on Floor #1: 1A, 1B, and 1C.
1A = 5 blocks
1B = 3 blocks
1C = 2 blocks
For 1A, BlockStart should = 1 and BlockEnd should = 5
For 1B, BlockStart should = 6 and BlockEnd should = 8
For 1C, BlockStart should = 9 and BlockEnd should = 10
And everything should reset back to the beginning on successive floors.
In T-SQL, I would use a cursor, and I assume I need to do the same kind of thing in Oracle, but I can't figure out the syntax.
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,

CREATE TABLE "SCOTT"."SEATALLOTMENT"

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

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.

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.
How do I loop through a Input parameter (varchar_table) and pass the input value to a select query.

1. How do I define temp_tbl and is it a best practice to use temporary table - if not what is the best method to do the same.
I wrote the following block :
set serveroutput on
declare
rec employees%rowtype;
cur SYS_REFCURSOR;
begin
open cur for 'select * from employees where rownum<:a' using 4;
for i in cur
[code]....
It gave errors if we execute is as such, but worked when I commented out the for loop and instead de-commented the simple loop. Does that mean that FOR cannot be used to loop through the records of a ref cursor ?
Can this be optimized, in dev and Ist we didn't realize since 1000 rows were there, but in PERF since 2 mil rows are there this is taking a long time,
SET SERVEROUTPUT ON
DECLARE
counter number := 0;
CURSOR insertValues IS select roleid, productcode, functioncode, typecode, restrictiontype, value1 from restrictions where actionmode = 'INSERT';
[code]...
can this be done in a single update since Selects /Updates are happening on same table
I can't seem to get away from writing php scripts to handle the update. I want to learn to use procedures more. What I have is a table like this:
courses(
id number(16) pk,
Division_title varchar2(100),
department_title varchar2(100)
I also have a temp table where I upload updated data into from time to time it looks like this
load_updates_courses(
id number(16) pk,
div_desc varchar2(100),
dep_desc varchar2(100)
)
Currently when I need to update the courses table, I write a php script to do the update. But what I really would like to do is write a procedure I could call to handle this.
I figured I need to loop over the recordsets in the update tables then do a update but I can't figure out how to get started with the plsql.
here i m giving the code

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?
