Field level validation

I was looking at the Add/Modify Customer page – page 7 in the Sample Application which can be loaded into Oracle XE and was surprised to discover that there doesn’t seem to be any field validation. For example customer first name is set to varchar2(20) at database level yet more than 20 characters can be entered into the application field and there is no error message when moving cursor focus to another field. Credit Limit field is numeric only but alpha characters can be entered and again, there is no error message when moving cursor focus to another field. Error messages are only displayed on hitting the Create button and even then they are standard ORA-99999 type messages – not very friendly to your average end-user I would suggest! I would be amazed if field-level validation (javascript maybe?) can’t be included in XE applications – assuming it can be, can anyone tell me how it works, even point me towards a working example – if I’m really lucky(!) Phil

As part of the page editor, looks in the center for validations. Right there you can enable all kinds of validations required for the objects in your page.
If you require you can use JavaScript to activate those validations also. Check the
Page Definition = Validation
You can use Item Validation or Page Validation.
A look to the APEX user manual will help with more examples on this.

Field level Validation in SAP PI

Hi All,
I am integrating with a 3rd Party system (File to Proxy scenario). Source file contains around 30 fields. I was asked to do field level validations for each of this field in PI. Is this a good practice. Do we do field validation in PI Integration development? I think PI should contain more of integration logic than field level validations. Please suggest.
Also out of all the 30 fields few are numeric, some are text and some are dates. While creating data types do I need to created all as string or based on their nature I need to use integer,date etc? Please suggest which is the best practice.
Thanks.

I agree with Rahul.
Yes we can perform validation in PI (most of the cases we do by request of the Business team).
But always have a thumb rule for your self.
1. Check first weather the source system is capable of doing the validation at its end.
2. If YES make sure the source system does the validations required. (I am sure most of the app would be able to the validation).
3.If NO then accept the validation process to be done in PI end.
One Important thing:
What kind of validation are you taking about? i assume this is field level validation rite?
and this is a Proxy to file scenario rite.
I will strongly suggest you to do following things at source and receiver Business systems.
1.gather a meeting the with the end business teams (source and receiver).
2.Force them to create data type at their end (sorce and target)with same data type structure- with same field length even.
ie, if source first field is integer with maxlen25 corresponding reciver field is also integer with maxlen25, if source has char field then in reciver also its char.
If you make both the source and reciever business to have same data type at there end, NO VALIDATION would be required to be done in PI
also in this case you can declare all the data type as STRING in PI and pass the data to receiver system. (which has the same data type as sender).

Field level validations for an Infotype

Hi,
Can anybody tell me if field level validations can be done for each and every field in a HR infotype?
Thank you.

You can do most of the validations using the Infotype User exit ZXPADU02 or the AFTER_INPUT mrthod in the BAdI HRPAD00INFTY.
But each & every field -- NO

Field level Validation in ADF

Hi,
We have some forms and we want to implement validation on field level. Means, as soon as i enter a value and move to next field, if the value entered is not as per desired regular expression than it should show the error. What i am trying is applying validator attribute on inputText and setting auto submit to true. It is working but some times page suddenly refresh itself and then the validation don't work.
Also one validation is to match the passwords (new password and confirm password). If i am using above method i am also not able to get the correct value of new password to match eith confirm password.
Can someone please suggest whats the right way to implement this functionality in ADF.
I am using jDev 11.1.1.4 and using Placeholder data control.
Please suggest
Thanks

If <af:validateRegExp> meets your requirements then sure, use it. The neat thing about the default validators will do both client side and server side validation. As such bypassing the JavaScript validators by sending raw HTTP requests to your server will still result in the required validation being applied via the server side.
For cross field validation, that's most easily done at the JSF bean level. It will require a round trip to the server to perform the validation though (rather than just validated at the client level). Is that an issue? There's an alternative solution but if you're not worried about round trips, go with the simple solution.

Field Level Validation - Date Mask

Hi all
I need some Java Script to validate a date mask in a field. Format must be:
dd-mm-ccyy.
Can anyone help me?
Thanks

Here is a copy of the script I set up to do validation.
I not only wanted it to check for a valid date,
but I wanted to store leading zeros, but not make the user type them in.
One of the things you have to do is to set the format mask for the date to MM-DD-YYYY for each date field in your form.
Here it is:
var DayArray =new Array(31,28,31,30,31,30,31,31,30,31,30,31);
var MonthArray =new Array("01","02","03","04","05","06","07","08","09","10","11","12");
var firstDash = null;
var lastDash = null;
var inYear = null;
var inMon = null;
var inDay = null;
var today = new Date();
var curFullYear = today.getFullYear();
var strYear = String(curFullYear);
var thisCentury = strYear.slice(0,2);
var thisYear = strYear.slice(2);
var numThisYear = Number(thisYear);
inDate = theElement.value;
if (inDate.length == 0) return true;
/* Check for a valid format. */
var filter=/^[0-9]{1,2}-[0-9]{1,2}-[0-9]{2,4}$/;
if (! filter.test(inDate))
{ alert("Please enter date in MM-DD-YY or MM-DD-YYYY format.");
theElement.focus();
theElement.select();
return false;
/* Pick off the indices (zero-based) of the two dashes. */
firstDash = inDate.indexOf("-");
lastDash = inDate.lastIndexOf("-");
if ((firstDash == lastDash) | | (firstDash == -1) | | (lastDash == -1))
alert("Please enter date using dashes (-), e.g. MM-DD-YY or MM-DD-YYYY.");
theElement.focus();
theElement.select();
return false;
/* Pick off the month and day (pad with leading zero, if necessary). */
inMonth = inDate.slice(0,firstDash);
if (inMonth.length == 1) inMonth = "0" + inMonth;
inDay = inDate.slice(firstDash+1,lastDash);
if (inDay.length == 1) inDay = "0" + inDay;
/* Pick off the year. Filter ensures 2, 3, or 4 digit year. 4 is what we */
/* want, so we only have to deal with 2 or 3 digit years. */
inYear = inDate.slice(lastDash+1);
/* If the user entered a two digit year, figure out which century to pad. */
if (inYear.length == 2)
/* Adding 5 years is still within the current century... */
if ((numThisYear + 5) < 100)
/* 00 to (current year + 5 years) should use the current */
/* century; otherwise, use the previous century. */
if (inYear > (numThisYear + 5))
inYear = (thisCentury - 1) + inYear;
else
inYear = thisCentury + inYear;
else
/* Adding 5 years would rollover the century, use the current century */
inYear = thisCentury + inYear;
/* A 3 digit year is an error. */
if (inYear.length == 3)
alert("Please enter date with either a 2 digit or 4 digit year.");
theElement.focus();
theElement.select();
return false;
/* Check for a valid month. */
var filter=/01|02|03|04|05|06|07|08|09|10|11|12/;
if (! filter.test(inMonth))
alert("Please enter a valid month.");
theElement.focus();
theElement.select();
return false;
/* Check for leap year. */
N=Number(inYear);
if ( ( N%4==0 && N%100 !=0 ) | | ( N%400==0 ) )
DayArray[1]=29;
/* Check for valid days for the month. */
for(var ctr=0; ctr<=11; ctr++)
if (MonthArray[ctr]==inMonth)
if (inDay > DayArray[ctr] | | inDay <= 0)
alert("Please enter a valid day.");
theElement.focus();
theElement.select();
return false;
/* Output the fixed up date. */
theElement.value = inMonth + "-" + inDay + "-" + inYear;
return true;

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

How to fix the field level Error(Invalid Date)

Hi All,
Error: 1 (Field level error)
  SegmentID: ACK
  Position in TS: 5
  Data Element ID: ACK05
  Position in Segment: 5
  Data Value: 162014
  8: Invalid Date
can anyone help me out, How to fix above error? i searched about this but only information about the error is given and no where it is mentioned how to fix it and how is it generated please help me out.
Thanks,
Nitish

Are you sending or receiving the EDI?
Either way, "162014" is simply not a valid EDI data format. Dates in x12 are expressed as CCYYMMDD so December 30, 2013 would appear as 20131230.
If you are receiving, you need to contact the sender and have them correct the output.
If you are sending, you need to property format that date value. For example:
myDateVar.ToString("yyyyMMdd");

Entity level validation

I have a requirement where there are two entities in a master detail relationship (A and B respectively linked through entity association)
EO A has a field called TotalQuantity (master)
EO B has a field called Split Quantity (detail)
The total quantity in the EO A to be split in the EO B, whereas the totals of the splits should equal the Total quantity of the EO A.
Can anyone suggest how to achieve this consistency by using an entity level validation.?
Please note that the EO A will be created and committed first, then only the child records are created(EO B). Both are not created and committed together.

for the sales Quantity you can have a validation on 'SalesQuantity' as 'Compare Validation' against the ViewAccessors attribute in the EO. operator as less than or equal to
for Entity you can have a 'Collection Validation' with the operaiton as 'Sum' with 'Equals' operator against the ViewAccessors attribute in the EO

Screen level validation on xk01 with holding tax screen .

Hi,
Can someone suggest a suitable way by which I can do screen level validation on xk01 screen 610,so that in case of
user not giving proper inputas the concerned field is open for user input .
Right now I am using an exit but it is triggered afete all data is collected form all sceens thus the error
appears on the last screen of the chaion and does not give the usr the option to correct the error.
He has to start all over again.

Attribute level validation

Hi ,
I have to perform attribute level validation between these two number type fields, when user tab out either from both fields if From size is greater then To size it fires and shows a message on From Size field, kindly tell me how to do that?
Jdeveloper 11.1.1.6.0
Regards,
Parvez

What you need, is a entity-level validator:
7.2.1.2 Entity-Level Validation Rules
All other kinds of validation rules are entity-level validation rules. These are rules whose implementation requires considering two or more entity attributes, or possibly composed children entity rows, in order to determine the success or failure of the rule.
The following examples are entity-level validations:
The value of the OrderShippedDate should be a date that comes after the OrderDate.
The ProductId attribute of an order should represent an existing product.

Recommended practice for handling page level validation?

I'm wondering what the recommended practice is for handling what I would call "page level validation?"
For example, I have two text boxes. Either one text box or the other must have a non-null value. If they are both null, I want the page validation to fail and redisplay the page the same way it would if validation for a particular field failed. However, I don't want the message that is posted to be associated with either of the two text boxes. I want it to use some other unique ID because I want to display the error text at a location that is different than for either of the text box error messages.

The reason I don't want to use a custom converter is because I'm using a custom tag/renderer which aggregates several HTML input components and has complex conversion logic. Maybe I could chain things together, but, a converter should be used for conversion not validation. Secondly, I don't understand why validation occurs after conversion. This seems backward to me.
One hack that I tried which almost worked was to create a custom tag/rendererer that was an input component, but, had no visible UI. I made that component always have a value which caused the validator to always be called. I made it so that it accepted a method binding as an input so that you could specify which validation method was called. I checked the component values for the components of interest using UIInput.getValue(). However, I ran into what might be a bug. Everything worked fine as long as the value changed to a non-null value. When the value was set to null, UIInput.getValue() was returning the old value instead of null. The strange thing is that the bean property that the component was bound to, ultimately was changed to null as I would have expected to. The problem was that UIInput.getValue() was returning the old value instead of null.
My current solution which isn't ideal is by using code similar to the following in my action method that my form submit button calls.
if(value1 == null && value2 == null) {
String message = "Validation Error: Value is required.";
FacesContext context = FacesContext.getCurrentInstance();
context.addMessage("id1", new FacesMessage(message, message));
return "validationError";
Note, I had to create my own custom tag/renderer equivalent of h:message because I couldn't get h:message to work. h:message couldn't find the message that I posted.
The down side to doing it this way is that the validation is occurring after the validation phase. Hence, the error message isn't displayed at the same time as other error messages. Furthermore, if you have more than one button on the form, you'd have to do the check for each action method.
This is really stupid. I can't believe something that should be so simple is so difficult in JSF. I'm planning on taking a closer look at ASP.NET. I'm pretty sure all you have to do in ASP.NET is override a method to do this and you have access to all the form controls as variables within the Page object. i.e. no having to lookup the controls using a method and a client ID.

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
Spam

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

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.
Amanda.

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.
