How to validate Date

Hi,
We have a date field in the form. I am validating date format as YYYY-MM-DD, validation works fine. But If user enters invalid date, how to validate date? For examples:
2006-02-31 It is an invalid date. How can i validate it.
If anybody have sample code, it will help me a lot.
thanks
Neopal.

Hi Neopal,
You can use something like the following to test the date is valid, use the validation event on the <Field> which you want to validate to call a Rule something like this (not complete)..
<Rule name='isDateValid'>
 <RuleArgument name='date'/>
 <block>
 <script>
 var dateToTest = env.get('date');
 var formatter = new java.text.SimpleDateFormat('YYYY-MM-DD');
 Date validDate = formatter.parse(dateToTest);

HELP! How to validate DATE?

Hello...
how to validate a DATE variable?
I have used SimpleDateFormat (dd/MM/yyyy).
For some input it worked fine, but for:
12/67/200394 (OK!) <- this is false, right? but not trapped!
1234546 (TRAPPED!)
12/324/1234 (OK!) <- this is false, right? but not trapped!
I need to have a 100% working Date validator.
Plz Help.
Thank you.

Hey -
I used to following code on your dates to get the results you were looking for...
import java.text.SimpleDateFormat;
import java.text.ParsePosition;
import java.util.Date;
public class DateFormatTest {
 public static void main(String[] args) {
 SimpleDateFormat df = new SimpleDateFormat("dd/MM/yyyy");
 df.setLenient(false);
 ParsePosition pos = new ParsePosition(0);
 String strDate = " 12/67/200394";
 Date date = df.parse(strDate, pos);
 // Check all possible things that signal a parsing error
 if ((date == null) || (pos.getErrorIndex() != -1)) {
 System.out.println("Error: " + pos.getIndex());
 if (date == null) {
 System.out.println("Date is null");
 if (pos.getErrorIndex() != -1) {
 System.out.println("Error index: " + pos.getErrorIndex());
}I hope there's something helpful in there

How to validate date picker value

Hi,
When a date is entered manually in the date picker .ie 01/03/08 the year 08 is saved as 0008 in the database rather than 2008. How to validate the value in date picker to save the year as 2008 instead of 0008.
Ven

The date picker does not always "store" the value for you - you create it with a particular format such as DD-MON-YY and then like any character to date field you need to be careful to use a format mask and to_date. Alternatively, change the format to DD-MON-YYYY.
Are you using this in a query or defined as a page item? Do you have the app on the APEX site?

How to validate date and timestamp format? Please help!

Hi experts,
   I have a input field "receipt_date" with is of char20 type. It contains date and timestamp value like 20090429T054509.000Z
   In my ABAP code I want to validate if "receipt_date" value is in the format YYYYMMDDTHHMMSS.MMMZ. If not then display error message. How can do this validation? Is there any existing function module that does this kind of validation? Please help!
Thanks & Regards
Gopal

Hi Gopal,
Can you check whether the FM CACS_TIMESTAMP_GET_DATE is available in XApps? If yes, use this to identify a valid timestamp.
Sample code:
    CALL FUNCTION 'CACS_TIMESTAMP_GET_DATE'
      EXPORTING
        i_timestamp = lv_stamp
      IMPORTING
        e_date      = lv_datum
        e_time      = lv_time.
Hope this helps! Do let me know if you need anything else!!
Cheers,
Shailesh.

How to validate data is in specific list while loading from SQL*Loader

I have a sample data file like below

I would like to validate 4Th column to be a valid color (ie) All color should be in a specific list, if it is not in the lis then the record should do to bad/discard file

How can do that while loading Data From SQL*Loader?Probably a lot easier with an EXTERNAL TABLE (they're much more flexible).
Is SQL Loader a mandatory requirement for some reason?

How to validate Date value in Text Column

Hi All,
I have entered DATE value in text item field(Char Data Type), Now how can i validate, the entered date is valid or not.
Thanks in advance.

Well, the easiest way would be to make the item of datatype DATE.
Another possibility is to try to convert the given value to a date in the WHEN-VALIDATE-ITEM-trigger, like
DECLARE
dt DATE;
BEGIN
dt:=TO_DATE(:BLOCK.ITEM);
-- if code comes here, the date is valid
EXCEPTION
WHEN OTHERS THEN
    -- seems to be no valid date
    MESSAGE('Error');
    RAISE FORM_TRIGGER_FAILURE;
END;Edited by: Andreas Weiden on 19.12.2010 12:23

How to validate data in editable ALV report after making changes

Hi Folks,
My requirement is to display data in ALV format with quantity field is editable. Once we get the data in display mode only quantity field is enabled right.

How to validate date using case statement.

I have date like 022212. I split month,date,year using STUFF Function. Now, i have to validate month in range 01-12 and date in range 01-31. Can some one help me with the query.
Thanks, Shyam Reddy.

That is not date; it is apparently a string (we have no DDL because you are so rude). Any competent SQL programmer will use DATE. You want help with a query, but there is no query.
CAST ('20' + SUBSTRING (crap_string_date, 5,2)+'-' + SUBSTRING (crap_string_date, 1,2) + '-' + SUBSTRING (crap_string_date, 3,2) AS DATE) AS redddy_screwed_up_date

How to validate date fields in the flash form

i want to validate the date fields to make sure the values
are not greater than today's date and from-date is less than or
equal to to-date in the flash form. Does the actionscript have a CF
DateDiff function for the validatation?
Thanks

I finally (after much reading up on actionscript) figured out
my problem with date validation...which was similar to yours...
I posted the solution I found for my AS date validation issue

How to validate data in SM30

Hi All,
I have one ztable with 2 fields. One for company code and other for G/L acc. I want to validate the G/L acc corresponding comp code. If G/L not maintain for corresponding comp code sys should give error in sm30.
How I can achive this.
Thanks,
Paras

Hi
Go to SE54 - Give the table name - Environments - Events
Using the code 05 enter a routine name (it can any name say "ZROUTINE" double click on that.. It will get you to a include with FORM... ENDFORM..
You have to write code inside this FORM ... ENDFORM
This code will be executed all the time before you create a entry.. Meaning as soon you enter details for a new entry.. this event will get triggered..
Generally any custom additional codes like validation, athourity-check, or some functionality to be built... evrything will be achieved only via EVENTS..
Let me know if you have questions
Thanks

How to Validate Date on Submit with Condition?

I want to validate the date field only when user enter a
data, otherwise it will pass as no vlaue when user click on submit.
var theDate2 = new
Spry.Widget.ValidationTextField("theDate2", "date",
{useCharacterMasking:true, format:"mm/dd/yyyy", hint:"mm/dd/yyyy",
validateOn:["submit"]});
Thanks

Hi helloha33,
You're probably going to have to do something like what
Dragos mentions in this posting:
http://www.adobe.com/cfusion/webforums/forum/messageview.cfm?forumid=72&catid=602&threadid =1221205&highlight_key=y&keyword1=conditional
Specifically, you'll add an onchange handler on your
<input> textfield which calls some function that will execute
the constructor call you mention above.

How to Validate Data from a JSP form

[newbie]
From a netui:anchor, I call a data entry form (dataEntry.jsp). It contains 5 textboxes created using netui:form and netui:textbox.
The user enters the new account info and clicks the submit button, a form bean is populated and passed back to the controller which calls a method to update the database. This all works well. At least it did, until I found that I could enter control characters into the form... So, this brought up the issue of data validation.
I would imagine there is a standard way to validate form data. (like checking a value is numeric or alpha, has a specific length or to apply a regex or edit mask prior to insertion into a database...)
Is it generally done within the jsp?, the form bean? or in the controller? The latter 2 would be java, I suppose. If it's in the jsp, are there jsp tag libraries for that?
Any direction would be most appreciated.
Mark
If I should be on another forum/newgroups (perhaps one for amateurs, please let me know... :>)

I believe I found the answers to my questions in some Beehive docs. I'll follow up if I have others... Mark

How to validate date columns in tabular forms?

Hi,
I have two date columns in a tabular form
1.Start_date 2.End_date so here i need to validate the end_date as should not be lesser value than start_date column
so any solution for this?

Hi,
use a validation of type "Function returning boolean" and the following code:
IF to_date(:YOUR_END_DATE,'YYYY-MM-DD') < to_date(:YOUR_START_DATE,'YYYY-MM-DD') THEN RETURN FALSE;
ELSE RETURN TRUE;
END IF;The date format is of course in your choice.
Hope this helps...
