Adding item level validation to a field

Hi All,
I am new to Oracle APEX.
I have a field named semester_code in my page and I want end user to enter only alphanumeric values. I want to create item level validation using regular expressions, but I don't know what expression to write for this purpose.
Any help will be highly appreciated.
Thanks
Bilal

Hi,
Go to the validations section of the application builder (for the application you are working on)
-> add item level validation
-> select the field that you are trying to validate
->item string comparison
-> select 'Item specified is alphanumeric' from list

Item Level Validations on Submit

Hello guys,
I would like to use Item level Validations but I have a problem. When I submit the page from a button the Item Level Validations automatically fire, can I not run the item validaitons when a specific button is pressed and not 'on submit'? If so how...
Thanks in advance

Hi "user502286",
in APEX 4.0 you have more control if validations (also the built-in one for required) should automatically fire during submit or not than in previous APEX versions. It's all about the two new settings
-) "Execute Validations" which is available in the "Action When Button Clicked" section of a button and
-) "Always Execute" for validations
Please consult the field level help for this attribute to find out how they should be set.
Hope that helps

Adding item level field to field catalog for a PPF for Outbound Delivery

Hi,
We wish to send a method call to an external system at the time of PGI of the Outbound Delivery Order for the combination of Product/Ship To combination.
Since Product is at item level and not in the standard field catalog, I added it to the field catalog in config, defined a new condition table, access sequence, condition type and maintained it in the right Procedure/Maintenance Group (Outbound Delivery).
Then I defined a new Action Definition, with a new method to send the details to the external system, but am confused on what Schedule Condition I should assign to this Action Definition. If I use standard Outbound Delivery Printing Schedule Condition /SCWM/FDO_PRINT, the PPF only triggers when I use the standard condition type 0DDN with the standard Access Sequence (no Product available). However if I use the new condition type (with product) with the same Schedule condition: /SCWM/FDO_PRINT, the PPF does not get triggered. The log in SLG1 simply says Condition is not fulfilled.
Can you please suggest
Do I need to work with my developer on building a new schedule condition which would look at the new condition technique I have condition records for? Or is there a non ABAP way of making this work?
Lastly, if my ODO has 5 items with only 2 products which have condition record, I want the PPF to be triggered 2 times for that Outbound Delivery.

Hi Experts,
Any update on the above request?

PO item level validation if create with ref to contract

Hi
Pl help me to fulfill the following client requirement:
When user create the PO with ref to contract , system fetch the all data from the contract to PO at line item level, but in the PO, user is able to change the contract line item rate.
Now contract line item rate is already fixed with vendor & PO creator should not allowed change this rate.
Could you provide the any standard configuaration or development to restric the user to chage the PO line item rate if created with ref to contract
Pl give me replay as soon as possible as it is very urgent
Rgds
Nishit

Hi,
First you have to create a separate document type which is to be used for creation of PO referring a contract . Than define functional authorisation to buyers going by the menupath -Materials management > Purchasing > Authorisation management > Define function authorisations for buyers-Function Authorizations: Purchase Order. Here enter the field selection key of the new PO document type you created . Than check the box "Display Prices" . Uncheck all other boxes .You can check reference to Contract against possible reference Objects. Than save . Than in the User id enter the User parameter EFB and allocate the aparameter to the user . Also remove other document types of POs except the newly created document type in user authorisations. This will prevent change of price field in the specific document type.

Item Level Validation Not Working As Supposed To...

Hi All,
I have an item validation type: SQL(Not Exist) that checks whether the value in the id number field exists in the database when Create button is clicked. If the id number exists in the database then an error message is displayed in line with the field & the transaction doesn't go through; however, when this happens Apply Changes & Delete button appear & Create button dissapear. It's as if the record has already been inserted. I would like this validation to work like the Not Null validations.
I repeated this process several times without success & now I can't even create a new user or update & delete existing ones - I get the error:
ORA-06550: line 1, column 7: PLS-00428: an INTO clause is expected in this SELECT statement
ORA-2015: User ID number already exists in the database.NB:The second message is the one I use whenever there's duplicates so, it's oracle reserved message. Any help is highly appreciated.
Regards
Kamo

The buttons probably have conditions to appear if a certain item is not null. You can set this item to null as part of the validation, e.g.,
:P1_X := null;
...but to do that you'd need to change the validation type to PL/SQL Function Returning Boolean and code the "not exists" logic into the PL/SQL block.

Why item level validation can only execute function but not procedure?

Dear all,
When execute my form, some parameter values will be passed to the text items.
Those values are the procedure name or function name for that particular item which are already defined in a package and those items are non-database items.
Suppose a particular item can be validated by a procedure or function. It depends on what value is passed into the program.
If the item when-item-validation is triggered, that corresponding procedure or function will be executed by calling the following codes A) or B):
A) EXECUTE IMMEDIATE 'BEGIN' || procedure || '(:1);END;' USING v_value;
OR B) DBMS_SQL.EXECUTE(...)
Basically, the form is working fine except 2 blocks which can only accept Function, i.e. only fired the function but cannot fire the procedure. Actually these 2 blocks are similar to the others blocks and they are also non-database blocks.
I am using Form10g.
Anyone have idea for that? Thanks for advance.
Regards.

You cannot use Execute Immediate in Forms. You have to do that on the server in a stored procedure.
You should not use DBMS_SQL either. In Forms, you use EXEC_SQL, which is almost the same, except for the error handling. And it is VERY slow, since you make a number of calls to it, plus one for each variable passed.
Now... if you call a function, it must return a value. If you write code to dynamically call a function, this process must be complex enough to handle the returned value. The same occurs if your procedure that you call has any parameters. If there are no parameters, then it would be simpler.
If you want dynamic function or procedure processing, then I would suggest you just pass the value being validated plus the table.column name to a server-side stored procedure or package, and do all the processing on the server.
Good luck... it won't be easy.

Item Level Validation in Detail Block

Hi Experts,
I have to Block Master and Transaction Block, When I am trying to enter the same item code in my Detail block it is accepting, but want to valid one one record will be there in my Details Block, please help me and send me some usefull code to solve this problem.
S P Mishra

The easy bit would be just a validation displaying the error message in the notification area. For this, one would just loop over the rows in the report for that column, checking each. If an error was found then return false. For displaying the error message under the actual row with the problem, one would have to do this manually. You could possibly do this using a div which has a class containing "display:none" and then manually set the style of the error'ed row in your validation routine. Would be messy but I'd imagine you could get it working.

Item Level Validation - on a page

I have condition where I have 2 item on a page. One is a check box and another Items is for entering the Number . I have to have a condition where When the Check box item is checked alone the next ITEM should run ITEM not NULL condition. If the Check box is left unchecked its ok for the ITEM to be NULL.

I have to check the condition for the "other ITEM" not to be NULL when "Check box ITEM" is Checked.
ITEM 1 - CHECK box
ITEM 2 - NUMBER
When ITEM 1 CHECK is CHECKEd
ITEM 2 should not be null.

Item Level & Page Level Validation..

Hi ,
What is the difference between Item Level validation & Page Level validation..
in which sceneario it will be useful.
Anoo..
Edited by: Anoo on Dec 16, 2008 5:04 AM

Hi,
From the APEX help:
* Item level validations are specific to a single item.
* Page level validations do not apply to any single item, but apply to an entire page.

Page level validation to prevent duplicate data entry into the database

Hello,
Can anyone please help me out with this issue.
I have a form with two items based on a table. I already have an item level validation to check for null. Now I would like to create a page level validation to check that duplicate data are not entered into the database. I would like to check the database when the user clicks on ‘Create’ button to ensure they are not inserting duplicate record. If data already exist, then show the error message and redirect them to another page. I am using apex 3.2
Thanks

Hi,
Have you tried writing a PLSQL function to check this?
I haven't tested this specifically, but something like this should work:
1) Create a Page Level Validation
2) Choose PLSQL for the method
3) Choose Function Returning Boolean for the Type
For the validation code, you could do something like this:
DECLARE
    v_cnt number;
BEGIN
    select count(*)
    into v_cnt
    from
    your_table
    where
    col1 = :P1_field1 AND
    col2 = :P2_field2;
    if v_cnt > 0 then return false;
    else return true;
    end if;
END;If the query returns false, then your error message will be displayed.
Not sure how you would go about redirecting after this page though. Maybe just allow the user to try again with another value (in case they made a mistake) or just press a 'cancel' button to finish trying to create a new record.

ToyStore Unexpected exception / Entity Level validation check question.

Hi,
JDev 10..1.2
I'm using the ToyStore Exception/Error handler.
I added an Entity level validation test by adding following test in the validateEntity method of my entity:
protected void validateEntity()
super.validateEntity();
if (this.getAccountStatus() != null && this.getAccountStatus().compareTo(Constants.NUMBER_20) < 0)
throw new JboException(ErrorMessages.class,"14000",null);
In the ErrorMessages class I added following line to the message array:
{ "14000", "Entity validation ERROR" }
I would have expected to see this error in the "global error section" but the exception was handled as a "unexpected exception" and was shown in the stack trace but not in the generated page.
Could you please tell me how to write an entity level validation error in the validateEntity method so that it gets displayed in the global error section?
I succesfully added attribute level validation and it gets displayed at the attribute level.
Here's the stack trace, notice that the message is retrieved from my ErrorMessages.class:

More info:
If I write:
<html-el:errors/>
I get all the errors displayed.
My purpose is to display the attribute level errors next is to each attribute and the Entity level errors at the top.
So at the top I wrote:
<html:errors property="<%= ActionErrors.GLOBAL_ERROR %>"/>
I added following trace:
At the beginning of the processException method:
System.out.println(getClass().getName()+".processException, ex: "+ex.toString()+", ex.getClass().getName(): "+ex.getClass().getName());
In the if block:
if (attrName == null) {
String errorCode = jboex.getErrorCode();
globalErrs.add(jboex.getLocalizedMessage(locale));
System.out.println("attrName == null, errorCode: "+errorCode+", jboex.getLocalizedMessage(locale): "+jboex.getLocalizedMessage(locale));
My trace:
05/08/10 12:19:44 com.photoswing.webview.actions.AccountCreateAction.processException, ex: oracle.jbo.RowValException: Failed to validate a row with key null of type WebAccountAM.AccountTestView1, ex.getClass().getName(): oracle.jbo.RowValException

05/08/10 12:19:44 attrName == null, errorCode: 14000, jboex.getLocalizedMessage(locale): Entity validation ERROR
Remark:
AccountId => pk, not mandatory,refresh after insert => sequence fetched in pre-insert trigger
