SQL & PL/SQL :: How To Update Multiple Records
May 6, 2010
I have a table formatted like this
ID|First Name|Second Name
1|X|X
2|X|X
3|X|X
4|X|X
and I want to insert First Name and Second Name records using the ID as the reference. The new data is currently in a .csv file, but I could put them in another table if that's easier.
ID|First Name|Second Name
1|Adam|Adamson
2|Ben|Benson
3|Chris|Christophers
4|Dave|Davidson
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.

for example my source is
emp_name sal
abhi 2000

is
begin
open p_cursor for
select sal into p_sal from emp;
if sal<2000 then
update emp set sal= sal+200;

end;
and i have called the procedure using following codes
set serveroutput on
declare
p_sal emp.sal%type;
v_cursor sys_refcursor;
begin
upt_sal(p_sal,v_cursor);
fetch v_cursor into p_sal;
dbms_output.put_line(p_sal);

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,
[code].....

I have a small requirement...
Create table temp_a (source_code varchar2(100), target_code varchar2(1000));
Insert into temp_a values ('1','002.0 AND 002.9');
Insert into temp_a values ('2','729.90 AND 079.99 AND 002.9');
Output :
1 002.0
1 002.9
2 729.90
2 079.99
2 002.9
So, once we get the output, it needs to be joined to another table. I did Google search, but most of them are retuning collections / arrays as output. Not sure how I join the collection with the table.
create or replace function splits
(
p_list varchar2,
p_del varchar2
) return split_tbl pipelined
is
l_idx pls_integer;
[code].......

I'm looking to create a STORED PROCEDURE to do the following per v1...but I seem to misunderstanding some ORACLE concept(s) as when called in a PLSQL window I'm getting an ORA-01422 message when using the V2 syntax.
Ideally I want this code called from VB, but for the moment I'm trying to get it to work when called from the PLSQL Developer toolkit. Am I trying the wrong concept? per previous posts my background is MSSQL, but I've used Oracle SQL from approx 2 years (at a SQL level) only.
v1
create procedure myabc
as
begin
SELECT custNAME
FROM MYCUSTOMER
[code]....

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 .

I'd want to select multiple records in my multi-record block. I'd also want to do that with checkboxes. When the user clicks on a particular checkbox, that should be selected and whatever record the user wants to check it should be added to selected records.

how to save multiple records at once i did coding like this:
declare
cnt number;
l_rec number;
f_rec number;
begin
cnt := 0;
go_block('aan');
last_record;
l_rec := :system.cursor_record;
first_record;
[code]....
but this works as saving the last record only, not saving the all records.

I have a form with two data blocks, one parent, one child block.
The parent is holds mineral lease info while the child holds the mineral owner info, such as addresses and phone numbers. One owner can be in the owner block multiple times (different owner types). The form only displays one owner at a time.
We have a separate master owner table which holds owner address. (We set it up this way because we get electronic info from mineral companies that we have to load each year).
As you tab through the owner block, it checks the FEIN against the master table and pulls updated address info from the master table.
I have a problem in which if an owner is on the lease multiple times, when you tab through the first instance, it pulls in the new address info, but when you go to the next instance, it won't update. If you requery, it seems that the first update actually updated all the owner records on that lease. How can I turn this off?

I have a situation where there are multiple records for a join criteria. I am trying to find a way to update a particular column for all the records returned by the join criteria. Example :
Table A
id number
1 1000
2 2000
3 3000
4 4000
Table B
id number
1 9999
1 9999
1 9999
1 9999
1 9999
1 9999
2 8888
2 8888
3 6666
3 6666
Result after update:
Table B
id number
1 1000
1 1000
1 1000
1 1000
1 1000
1 1000
2 2000
2 2000
3 3000
3 3000
update query ? When I use a update statement with where exists it errors out because the query returns more than one row for the join condition.

I have a service that executes a pl/sql function (legacy app) to delete records from multiple tables. This function works fine in development, and has worked fine in production until about a week ago. I'm not a DB guy but the DB guys are trying to say this is an application issue. That may be, be the "insuff privileges" really leads me to believe otherwise.
What is causing this type of Oracle error? Permissions between dev and prod are the same, yet it works in dev but not prod.
ORA-29876: failed in the execution of the ODCIINDEXDELETE routine
ORA-20000: Oracle Text error:
DRG-50857: oracle error in textindexmethods.ODCIIndexDelete
ORA-20000: Oracle Text error:

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);
[code]....
get the result using a single update statement.
