Forms :: How To Create MASTER_DETAIL Form Manually
Oct 25, 2013
I know how to design master_detail form using wizard but i want to create it without using wizard.I have created two blocks emp and dept without using wizard ,and connected them to emp and dept table by changing their properties.Now i want to create relationship between these two blocks, My requirement is when i press execute_query button if deptno is 10 in dept block then emp block should show data for deptno 10 only.
I know it can be done using add relationhip option in dept block (which is master block)but how to do that.
I have install Oracle 10g Database software in Red Hat 5.9 64bit. When I want to create a database manually (not using DBCA) I am getting errors like follow:
[oracle@t24app2 ~]$ export ORACLE_SID=dbend08 [oracle@t24app2 ~]$ sqlplus / as sysdba

Grid Version:11.2.0.3OS : RHEL 5.8 I have succesfully installed cluster (GI) and installed RDBMS software on my 2-Node RAC . But, I don't want to use dbca to create the database due to some custom requirements. Instead , I want to run CREATE DATABASE command manually to create the RAC DB. Once the DB is created in one node, what are the steps I need to do to make this DB a RAC DB?
i create a form for ordering>>>that the person can enter his/her information and isbn book to make the order,but the order id i make it sequentially! well first of all i create a data-block and i insert only the oid in trigger when-new-item-instance..i had create the sequence:
declare create sequence seq1 start with 90 increment by 10; end;
and i make a view form such of fields that user can enter a details o what he/she want to order!!
1- is that enough?
2- it seems there is an error in creating the sequence?? wrong way to create the sequence!!
I have made few forms , but i want only those users to access these forms who have valid login and password to access these forms.
For example i have created one form employee details (shows the details of emp table in tabular form) which is based on emp table. The users are scott having password tiger ,and User Test having password Test. i want to make a login form to give access to only these users to access employee tables. if someone else tries to access it then it should show Unauthorized login error.
My requirement is i want to create a basic login form which includes
what should be the queries behind these items. and how to connect this form to database. I am attaching file , just add working codes in that or you can write codes here also .
I know how to create sequence in the database.But I want to create this sequence from the form by giving the name of the sequence from a filed in the form.
I just need to create a login form ..its like user will login using his given id and password will be encryted when entering and i just need to simple validation that if he has entered corrected password it will display message ok or else wrong password.
I have a form with a datablock displaying 3 text item fields.But the actual oracle table have 8 columns.When ever I insert new data and save it, only the three records are being stored in backend whereas remaining column stores with null value.That is the basic function of the form.
I placed an another list item field in a control block which is non-database item.Now I want to store the list item value into a column along with the 3 columns.In a simple way, how to insert record manually along with the other records?
//when-validate-item declare i number; begin if :a.b is null then i:=show_alert('null'); else if :a.b between 1900 and 2013 then message('date valid'); else i:=show_alert('date_invalid'); :a.b:=null; raise form_trigger_failure; end if; end if; exception when others then i:=show_alert('exception'); end;
the problem for example when I entered a value "3000" I received two messages (the first on the alert "date_invalid" and the 2nd on the exception message) but normally I must received one message, the relative "date_invalid"
I cann't commit form when new instance form with form status is "NEW".
And then i call: Text_Item := WebUtil_File.File_Selection_Dialog('', '', 'Excel 2003|*.xls|Excel 2010|*.xlsx|All File|*.*', 'Select a file to Import', Open_File, True); Form status change to "QUERY"
And then i click button "Import Data" from excel file to Data Block. Now form status change to "CHANGED". But i cannot call "Commit_Form" built-in to insert data to database oracle 10g.
I want to call a Web form which should upload the image from my local machine.For that I have created a form which will take necessary data about employee now I want to Insert Image for that employee into table as I am new I struct on the Image uploading form. Latter I have seen the Enter & Maintain form which have Picture button.Pressing this button we get one new web form open & we can upload our image from there.
I have FORM_A calling FORM_B: Call_form('FORM_B',...). On form_B I am updating a Record and when I close Form_B and the focus goes back to Form_A, I need to Automatically Reload Form_A to reflect the changes that were made on Form_B.
How can I reload the Calling Form (FORM_A) when I closed the called form (FORM_B)?
I want to convert my forms6i application into forms9i therefore I initially converted my login and explorer form.
In my login form, I am using NEW_FORM to close my login form and wants to activate my explorer form but every time a pop-up raised and asked "DO YOU WANT TO CALL THE NEW FORM?", if I pressed YES then pointer moved to explorer form.
This form is working perfectly in 6i and didn't asked anything and moved to successfully to explorer form.
I have developed report in reports9i and executing this report at application server but the parameter form is not displaying as its displayed in report builder.
parameter form isn't in descriptive format like you can check the department field. how to create parameter form in descriptive format or I am doing any mistake?
using apex 4.1, created tabular form for inserting values from customer with a simple query
table name : customer select USER_ID , USERNAME, PASSWORD, STATUS, PRODUCT_ID from CUSTOMER
I WANT TO FETCH THE NAME OF PRODUCT FROM ANOTHER TABLE NAME PRODUCT_NAME, I WANT THAT WITH TABULAR FORM COULMN OF PRODUCT NAME IS ALSO DISPLAYED, HOW I DID THAT ? JUST WANT TO ADD COLUMN FROM ANOTHER TABLE IN TABULAR FORM.
WHEN I ADD TABLE NAME IN FIRST QUERY IT IS NOT WORKING GIVING ERROR ABOUT NOT JOINING THE TABLE
Is it possible to create a validation for tabular form which will be fired only for created?
There is a possibility in APEX 4.1 to choose two types of "*Execution scope*" first is "*For created and Modified Rows*" and second is "*All Submitted Rows*".
I understand everything -- <gripe> need better Automated Row Fetch (ARF) documentation </gripe>, but I now have CREATE, QUERY, and DELETE working and I can choose to clear the form (or NOT). And I don't claim this is the best or simplest or most-efficient or most straight-forward approach. It's one virtue is that it does seem to work.
I need to be careful state that this involves both Automated Row Processing (ARP) -- which enables INSERT, UPDATE and DELETE. And Automated Row Fetch (ARF) -- which enables SELECT. ARF is found under Page Rendering and ARP is found under page processing. As we have seen, the two are -- or can be -- interdependent. For example, I believe the error I talk about next is caused by ARF trying to fetch the record just deleted by ARP.
Starting from the situation of
1) having the values retained on the screen when CREATE is clicked and the record is added and 2) getting a database error after a DELETE of a row, A solution is the "reset" processes. Under Page Rendering add a "reset page" process to: "Clear Cache for all Items on Pages (PageID,PageID,PageID)" and indicate the page with the database operations and under Conditions: When Button Pressed: choose CANCEL, CREATE, DELETE, QUERY or SAVE. I made two of these - one for CREATE and one for DELETE. To cover both buttons, you need two processes as you can only indicate one button per process.
Now the form (screen) is cleared after the CREATE (by process 1). And since it's also cleared after the DELETE (by process 2), there is no Database error on DELETE.
(The source of that error was ARF trying to retrieve the deleted record because the PK field had the "just deleted" key value. This nulls it and I have ARF set not to attempt a fetch when the key field is null.
So, how about that? Burleson has an example here which adds more detail than I recall seeing before.URL>....
I think the DML Fetch Mode settings he shows are new to the ARP screen in 4.2. I don't see them in 4.1.
