There is a need for me to UPDATE a DATE column from one date to another. So as an example,
we have TABLE A and Table A has a column (DATE_TO) with date field value off
DATE_TO
31-DEC-99
12-APR-15
15-MAR-16
What I want to do is update '31-DEC-99' to '31-MAR-13' and for it to only effect '31-DEC-99' (the others are fine).
Environment:
Apex 4.2
DB 11gR2
I've started using Apex 4.2(new to Apex). I have built a form based on a table with a date column on it. The form allows update on all fields/columns of the base table. For the date field/column, the goal is to present the user with sysdate on load and update the date with sysdate if the record is changed any of the fields. How can I accomplish this?
I'm trying to work out how to take a table like this:
IDDate
12502-Feb-07
12516-Mar-07
12523-May-07
12524-May-07
12525-May-07
33302-Jan-09
33303-Jan-09
33304-Jan-09
33317-Mar-09
And display the data like this:
IDPeriodPeriod StartPeriod End
125102-Feb-0702-Feb-07
125216-Mar-0716-Mar-07
125323-May-0725-May-07
333102-Jan-0904-Jan-09
333217-Mar-0917-Mar-09
As you can see, it's split the entries into date ranges. If there is a 'lone' date, the 'period start' and the 'period end' are the same date.
I am not able to load complete date along with time in the date column. here is my table desc
DESC STAGE
Name Null Type
----------------------------------
TABLE_NAME NOT NULL VARHCAR(20)
RECORDCOUNT NUMBER
CREATED_DATE NOT NULL DATE
my control file is like this
LOAD DATA
APPEND
INTO TABLE SCOOP.STAGE
FIELDS TERMINATED BY ","
( TABLE_NAME
,RECORDCOUNT
,CREATED_DATE DATE(16) "YYYYMMDDHH:Mi:SS"
)
the data gets loaded, but it appears like this in the table
HIGHSCHOOL3080606-JUN-12
MIDDLESCHOOL8768006-JUN-12
BUT I WANT COMPLETE DATE AND TIME (HH:MI:SS) , HOW CAN I GET IT (THIS IS HOW I WANT 06-JUN-12 11:07:33)
How can we partition a table based on date if it does not have a date column.
Actually I have to compare two tables on daily basis and fetch few rows from those two tables and enter it to a third table.But both these tables does not have a date column.
I am confused if i need to alter those tables and add date column or if there is some way in which i can compare the data from the two tables for that particular day only and not the whole table data.
i have a table with the following description
create table gl_periods(period_name varchar2(10),transactions number (2) );
with the data as :
period_name transactions
------------ --------------
JAN-10 12
FEB-10 12
MAR-10 8
APR-10 23
ADJ_TOM-10 25
MAY-10 37
JUN-10 41
JUL-10 10
PHY_JAY-10 6
AUG-10 14
SEP-10 22
My requirment is to find out the period names and transactions which are in valid date formats and are less than sysdate and the non date formats are adjustments made by different users for their transactions

I have a partitioned table with ~50 million rows that was setup with a number(10) instead of a date column. All the data in the table is ALWATS in this format YYYYMMDD

DAY_DK NUMBER(10) NOT NULL
)

When I use the exchange partition method the parition is able to move the data from "monthly" table to "mth" table.
desc t1.mth; ### my temorary table
Name Null? Type
----------------------------------------- -------- ----------------------------
SEQ_NUM NUMBER(10)
DAY_DK NUMBER(10)
Than when I try to alter my temp table "mth". I get an error table must be empty to change column types.
alter table n546830.mth modify (DAY_DK date);
Next I tried making my temporary table "mth" a date column. When I an the exchange partition command I get the following error:
alter table t1.monthly exchange partition DEC_2012
with table t1.mth without validation;
alter table n546830.monthly exchange partition DEC_2012 with table n546830.mth without validation

ERROR at line 1:
ORA-14097: column type or size mismatch in ALTER TABLE EXCHANGE PARTITION
Method I can use to convert a number(10) to date column and keep the information in a table. Note, I don't care about HH:MM:SS as I never had that information to begin with and would be happy to set that part of the date column to all zeroes "00:00:00"
I was wondering how can I do below statement in oracle
update table1 t1 set t1.column1 = t2.column2
from table2 t2 inner join table3 t3 on t3.column3=t2.column4
where t3.column5 is null
I tried read up merge and update, but not really understand how the syntax works in oracle.
As all of you know, In the Apex, when you create a form with report in the page, you are able to insert and edit data. But when you edit the data, the data will be modified in the same row. In other word, you loose the old data.
What I need to do is: I have revised_num field and production_date field. I want to create a form with report and insert and edit data as is in the apex and insert 0 to the revised num until production date is null. But when production date is not null, then from that point, I want to insert data to another row and modify revised num to 1. and I want the revised num be incremented by 1 each time the user modifies the data after the production date is not null.I don't know where I should start.
When I try to update a date column with this:
UPDATE
event_request
SET
REQ_EVENT_DATE = TO_CHAR(REQ_EVENT_DATE - INTERVAL '1' HOUR, 'yyyy-mm-dd hh24:mi')
WHERE
eventID=123
Oracle returns this error:
ERROR at line 4:ORA-01861: literal does not match format string
where line 4 is REQ_EVENT_DATE = TO_CHAR(REQ_EVENT_DATE - INTERVAL '1' HOUR, 'yyyy-mm-dd hh24:mi').The REQ_EVENT_DATE field was originally populated with this stripped down query:
$date = '2007-12-25 08:35'; INSERT INTO (REQ_EVENT_DATE) VALUES (to_date('$date', 'yyyy-mm-dd hh24:mi'));
So - what is wrong with the UPDATE query?

i have creatd view,in which i need to show the entry of year in column wise,though the data is in row /record wise.By iteration i can manipulate the year in decode function like " (DECODE(a.Year,(select distinct max(year)-1 from BI_BALANCE_SHEET), a.Balance))",but is there any way to chachge the alias name /column name,here is the query
select

While updating a table, is it possible to get the old value of a column. I need to get it inside a PLSQL block and not in a trigger.for example :-
DECLARE
l_amountNUMBER(5) := 0;
BEGIN
UPDATECustTransactions
SETamount = 150
WHEREcust_id = 5412
RETURNING amount INTO l_amount;
DBMS_OUTPUT.PUT_LINE ( 'l_amount= ' || l_amount );
END;
By using the RETURNING clause i am getting the new updated value. I need the old value for some processing. Do i have to explicitly query it before the update stmt? Pls reply.
I am having a table with out a primary key .It also contains data.
My requirement is to add a new column to the table and update the column value with unique and sequential number , starting from 1 to end of rows.
This has to be done without using a sequence.

View 2 Replies View RelatedDoes "Update on a Partitioned Column" cause fragmentation ?
See example below :
Suppose I have a table as below that has approx 3 million rows and growing :
1) Table ABC :
file_id number
status_flag varchar2(1)
file_Content clob
date_created date
2) This table is list partitioned on Column "status_flag".
Column "status_flag" can take 3 values "A" or "B" or "C"
3) A file_id can transition from 1 "Status_flag" to another. [ A--> B , C--> B, B-->C, A --> C, etc ]
This means its possible to UPDATE the "status_flag " - the partitioned column.
Question :
-------------
1) Would the movement of rows from 1 partition to another cause fragmentation ?
2) Or Instead, should this be achieved by maintaining 3 tables - 1 each for every "status_Flag" as Table_A, Table_B, Table_C
This would mean that, if file_id 1, changes "status_flag" from 'A' to 'B' :
-- The corresponding row from Table_A will be created in Table_B
--- The same will be deleted from Table_A
This would still cause fragmentation ... with the overhead of Inserting a CLOB column from 1 table to another.
3) How to determine how much percent of the table is fragmented ?
my need is to perform merge - update when id column is matched, but one of others columns not.When id column is not matched then I perform insert.
It works fine for matched or not matched id column.
Commented code is my try to perform check for others columns, The code should not update when all columns match. It should update only when on of columns doesn't match (except id column of course, because it's key column).

merge into copy.table1 rr
using
(
select
ID ,

I am encountering an error message while updating a xmltype column using dynamic sql statement. I am using dynamic sql here as the table is not placed in the same schema from where the plsql procedure is invoked. The schema name is passed to the procedure as an argument. I am using below pseudo code for this purpose.
Create procedure myproc(p_schemaname varchar2, p_id number)
is

p_str varchar2(2000);

This is throwing an error 'missing expression' at the line of 'exeute immediate'.
But it works if I run a static sql update by hard coding the schema name in the statement.
