I am using Forms 6i and developed a Master Detail Oracle Form for Oracle EBS 11i application.
I was asked to write a pl/sql program so that.. When a user updating an existing record at the same time another user query the same record and try to update the same time, the record should be locked and a message should popup saying the record is being updated by another user.
when I updated a record in my form check my screenshot: and clicked save button the result was:
as you can see in the message at the bottom, it has 18 records. And since my original data(subjects) are just 9. And also the grades that I input didn't display all.
This is my code in when-new-block-instance trigger:
DECLARE
CURSOR studgrade_cur IS
SELECT e.student_id, s.subject_code --, g.grade
[code]...
SELECT COUNT(*)
INTO v_ctr
FROM leave_type_govt_service
WHERE (
:block_name.min BETWEEN minimum AND maximum
[code]......
This code in my forms really works for inserting a new record. But if I will update the record itself for example, in the table 'Type 1'
Minimum Maximum
1 5
6 10
11 15
and I will update the 6 - 10 to e.g. 7, It must update but my query includes 6 - 10 data so it raise the trigger failure.
Note: The AND condition in the last part is for unique types. Because even if e.g. 'Type 2' has a Min and Max data same as the 'Type 1' the trigger will not prompt.
I have a question. If we have two scott sessions. I am updating a table EMP in session
1. It means it is exclusively locked.It cannot be used by session 2. Then can we use select command on table EMP in session
2.? This command should not work according to me. But it is working.
My user tablespace has been full and just I create new tablespace like User_Tablespaces.
I want to Alter Default Tablespace and Quota define of all existing user on User_Tablespaces.
How we do in a SQL Query or PL/SQL query that can all existing users has been alter at a time in a single query.
i've created a schema, which contains 30 tables. the tables are accessed & updated through a web based application. i've made public synonym for all tables for some reasons. how can prevent any one other than application users from updating the tables from Sqlplus.

whether i create first a lov and record group at design time or not? if i create a lov and have the recordgroup column then what is the benefit of dynamically lov.?
we can easily find out the locks which are currently active session.
Is any other way to find out locks on particular date and time using data dictionary?
For example, we have to find whether TT_objects occured the lock or not on ON yesterday.
Using 11gR2, windows 7 client machine. I need to update the table missing_volume (below), where I need to calculate the estimated_missing column. The calculation of estimated_missing column for current month needs previous month numbers (as commented inside the code below). I want the output like the first table. Notice the records start from January, hence estimated_missing for January can't be calculated, but for the the rest of the months it can be done by simply changing 'yr' and 'mnth' (commented inside the code towards the end).
yr mnth location volume actual_missing expected_missing estimated_missing

[Code]....
The code does calculate correct number for 'estimated_missing' as I run the code for each month, but the problem is while updating the current month it also erases the record for previous month. E.g. as can be seen below, after I updated April the column only has the record for April, previous month record is gone, similarly updating March removed February, etc. I can't understand why it's happening!! Here is the output I get:
yr mnth location volume actual_missing expected_missing estimated_missing

why it's happening (I mean where is the flaw in the code) and how to get the desired output (first table).
I have multirecord block and I want to disable Inserting/Updating/Deleting more then one record at a time.

is there any possibility or hint to avoid updating record if columns do not change? For example, I have UPDATE:
UPDATE MY_TABLE SET COLUMN_A = 'ABC' WHERE COLUMN_B = 12
if the value in COLUMN_A is 'ABC' I do not want to do this update. Of course I can add in WHERE 'AND COLUMN_A<>'ABC' but when I am updating a lot of columns it will be annoying

I have a page which downloads statspack reports from different servers and stores them in APEX. As well as this it also display a summary of data (top 5 wait events & load profile info) when hovering an icon: [URL]... The chart will refresh itself and display the data based on the value of P10_SNAPVAL (storing the PK value). The report does not do as I expect it to do (it isn't refreshing the table).

I am trying to create and update query to use as a trigger for updating information in a database which is dependent upon time.
I have a severity level which needs to be decreased in value after a set amount of time. the time of the action is recorded automatically on the creation of the the record. after an hour anything at severity level 2 needs to go up to 1, after 2 hours level 3 goes up to 2 and 3 hours level 4 goes up to 3
so far this is what I have
UPDATE calllog
SET timedate = current_timestamp, severityid = severityid - 1
WHERE ((severityid = 2 and timedate >= current_timestamp + (1/24)) or
(severityid = 3 and timedate >= current_timestamp + (2/24)) or
(severityid = 4 and timedate >= current_timestamp + (3/24)))
I am not getting any errors back from this sql but it is not updating the relevent information. I am using one cell for time and date in format = DD-MON-YYYY HH24:MM:SS.
we know we can see lock mode held in session can be analysed using LM column in v$lock.But i confused in seeing LM column it all shows in numbers from 0 to 6.

3,'Row Exclu(3)',
4,'Share(4)',

View 27 Replies View RelatedI have a fairly standard Purchase Order form which contains pre-loaded data (been uploaded from an XML file).When the Purchase Order is processed, the form updates a Price History table only if the Price on the PO_Details changes.The code for updating the price history table is contained in a PRE_UPDATE trigger on the PO_Details Data Block.
No other data changes on the PO_Details table.I now want to change this so that the Price History table is updated even if the price does not change i.e I want to create a history record for each record on the PO_Details irrespective of whether it was updated or not.
Is there an alternative trigger that I can move my code to (ie move it from PRE_UPDATE) to some other trigger that is fired for each PO_Details record even if there is no change.
I create a data block on a table when I am inserting new record only one record have been saved. Last record no longer exist.
View 4 Replies View RelatedWe are in the need of calling Mapping Software from with in Forms, most likely Google Maps, and keep the form locked until selections are made. The attempt was to call the URL from a Modal Window that would in turn lock the form until return.
The attempts were using WEB.SHOW_DOCUMENT, this process releases the form as soon as the call occurs. Then the desire to use UTL_HTTP, but with this process it would cause the DBA to setup a Wallet_Path for Certification of the call. This one has not been explored as yet.
