Forms :: How To Get Values From DB Before Update
Feb 11, 2008
I want to know about if I want to store previous values of a table row before updating through Forms, like in Database Trigger where we are referencing old values as :old.etc to get Values Before Update, how I can achieve this in Oracle Forms 6i or above versions.
for example: I made a form Employee to manipulate data by a user, if user update a record I want to store previous values before Commit in trigger Pre-Update with some additional information. I do not want to use a Trigger on that Table.

updating the column values.
Test data:
CREATE TABLE test_at(nr_a NUMBER, nr_id NUMBER) TABLESPACE ECLP_DATA01
INSERT INTO test_att VALUES(90270091,NULL);
INSERT INTO test_att VALUES(90270091,NULL);
[Code].....
I need to update "nr_id" column of test_at table with the values from test_d table. They can be udpated in any order.

I have a table called 'price' and want to update it with a table called 'update'. See workbook in the attachment.
The idea is to update the table 'price' with values from 'update' as long as the values from 'update' are different then the values in 'price' or the value in price with 'enddat' empty is not present in 'update'. you can still follow this...
Example:
Enddat for df_location 4 from 'price' is empty and df_location 4 is not present in 'update' so 'enddat' for this df_location should be filled with any date from 'update' (there is always going to be just one distinct date).
I have tried something like this:
proc sql;
insert into work.price (enddat) where enddat = ''
select (date) where df_location not in (select
df_location from work.update);
;
quit;
Well this obviously doesn't work. I'm trying to pass 2 criteria (when enddat is empty and df_location is not present in 'update') but I'm not sure where to put them...

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?

how can i make this script into a function or procedure which instead of user change the crime_id :=4 or 5 directly it actually can grab the id from a update statment like
UPDATE CRIME_STATUS SET CRIME_STATUS = 'open'
WHERE CRIME_ID = 9;
pick 9 and insert into the above statment so it runs as normal

Updating multiple ROWS with different values using single statement. Requirement is to update one column in a table with the values in the other table.
Say we have 3 tables, CORPORATION,CORPORATE PROFILE and MEMBER.
Each MEMBER has CORPORATE PROFILE which in turn is associated with CORPORATION. Now I need to update MEMBER table with CORPORATION identifier for members who belong to corporations with identifiers say 'ABC' and 'DEF'.
MEMBER table contains column 'CORPIDENTIFIER '. CORPORATEPROFILE table contains MEMBERID and CORPORATIONID,this will associate a member with the corporation. CORPORATION table contains ID and CORPIDENTIFIER.
Using the below query I am getting error,ORA-01427:single-row subquery returns more than one row
UPDATE MEMBER M SET M.CORPIDENTIFIER=
(SELECT A.IDENTIFIER FROM CORPORATION A,CORPORATEPROFILE B
WHERE B.CORPORATIONID=A.ID AND B.MEMBERID=M.ID AND (A.IDENTIFIER LIKE 'ABC' OR A.IDENTIFIER LIKE 'DEF'))
Sub query in the above query returns multiple rows and hence it is throwing the error.More than one members are associated with Corporations ABC and DEF. Is there any way possible to update all the rows in single query with out iterating the result set of sub query.

I have a large table and want to calculate just a few values. Therefore, I don't want to create a new table, I want to update the table. Here an example:
I want to calculate the VALUE_LAG with ID = 4 only (-> two values).
create table zTEST
( PRODUCT number,
ID number,
VALUE number,
VALUE_L1 number );
[Code]..
I tried this, but obviously, windows functions are not allowed in the update statement.
update zTEST
set VALUE_L1 = lag(VALUE) over (partition by PRODUCT, order by ID)
where ID = 4
How can I do this?

I have a query like this -
SELECT
FIELD_A,
FN_FUNCTION(CARVE_ID, 1) FIELD_B,
FN_FUNCTION(CARVE_ID, 2) FIELD_C,
FN_FUNCTION(CARVE_ID, 3) FIELD_D,
FN_FUNCTION(CARVE_ID, 4) FIELD_E,
FN_FUNCTION(CARVE_ID, 5) FIELD_F,
FN_FUNCTION(CARVE_ID, 6) FIELD_G
FROM TB_CARVE;
When I execute the query, it returns the data (approx - 40,000 rows) in 1 min.But when I try to insert this data into another table (or create a table of this data) it takes me about 2 hours.
Tried using Materialized view, its again the same the refresh takes 2 hours.Basically here, what I am trying to do is the data from the above query is used to update the values in another table.What ever the procedure I am trying it takes 2 hours.

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?

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]....

Application Express ver. 4.1
I have created a form. Some of the elements are hidden such as updated_by and update_date. I have provided the default values for these attributes as pl/sql expression in the "default section" (Application->page->edit page item). I am using the Process Row process that is automatically created when a form is created.
The problem is when I click the update button, the updated_by and update_date is passed as null values which throws an error from the database.

I'm trying to update a number field on an apex page by summing up the values of multiple page items. I've tried to follow this tutorial
[URL]........
especially the "Create a Set Value Dynamic Action Using PL/SQL" part.
In the tutorial example they return an page item value P3_SAL multiplied by a multiplier they've determined by another page item's case. What I want to do is much simpler in that I just want to add up multiple page item values and then display them in a number field at the bottom of the page.
so the code I tried to use based on the tutorial is in the tab: Home >Application Builder>Application 103>Page 3>Edit Dynamic Action>Create / Edit Action
Set Type: PL/SQL Function Body
PL/SQL Function Body:
BEGIN
return :P3_ITEM1+P3_ITEM2+P3_ITEM3;
END;
Page Items to Submit: P3_ITEM1,P3_ITEM2,P3_ITEM3
But it gives me an error that I need to declare the identifiers, yet it works if I only use one item and I can perform any arithmetic.
i.e.
BEGIN
return :P3_ITEM1+1000;
END;

I am working on a simple form which will get the user to fetch required columns of employee master.
For that i have created a form which will display the column names and select option. When user clicks on query, the form will display the selected columns in a block. After going thru if required the user can download it to excel.
As of now I do not have filtering option. For this I thought of creating view based on the selection and then fetch records from the view and display it in form.
To achieve this I would like to know How I create or replace a view dynamically based on values selected. I remember doing this sort of thing long back, but could not recollect it.

I've tried to Update table with values from another table, but I couldn't.Is there a single way to do that with just one query?Below goes an example:
CREATE TABLE TEST1 (

COD NUMBER,
DCR VARCHAR2(10),
DCR2 VARCHAR2(10) );
[code]....
I want to UPDATE the field DCR of the table TEST1 with the VALUE of the field DCR2 of the table TEST2.At the end, after the update, the table TEST1 would be like that:
SELECT * FROM TEST1
COD --- DCR

check my query and correct it basically I want to insert/update data from one user to other therefore I write this coding at my form button, when user press button first time its insert data successfully but if user press button again then it should update because data have been inserted in first step.
Actually it is detail table so it can have more then one record against any master. My query fails in updation, it inserts a new record instead of update.
find the attached file for checking QUERY.
