Date format error while accessing date from SQLSERVER

Question

Hi all, in me webdynpro application I have taken Date type for the Input Field.
At date select it is displaying in the format
  *2/14/2009 i.e. mm/dd/yyyy*
And when I am saving date in the sql database then the date format changes to..
2009-02-14 i.e..yyyy/mm/dd.
But using the Date format method I have changed the format as per the need to push date in the SQL database table...
In the table SQL the date attribute is in form i.e.    02/14/2009 as like from the date select from the date Input Fieldu2026But the problem is that database is not being able to display in that Input field again.
I have use the coding both at Insertion and selection of the database i.e..
Date Sdate, Edate;
Sdate     =   Date.valueOf (rs.getString ("Sdate"));
Edate     =   Date.valueOf (rs.getString ("Edate"));
SimpleDateFormat date Formatter = new SimpleDateFormat ("MM/dd/yyyy");
Sdate = wdContext.currentProjectElement ().getEdate ();
Edate = wdContext.currentProjectElement ().getEdate ();
  String Sd = dateFormatter.format (Sdate);
  String Ed = dateFormatter.format (Edate);
  Date Sdd =Date.valueOf (Sd);
  Date Edd =Date.valueOf (Ed);
But at selection of the database the error for the date format isu2026.
java.lang.IllegalArgumentException
If somebody knows how to resolve this ,plz let me know

Answer 1

for displaying the value only, I think, you are converting to string.
sol1:
1. Create a simple type in dictionary: under Dictionary -> Local Dictionary -> Simple Types
2. go to Definition tab: Change Built-in Type as Date
3. go to Representation tab: specify format e.g.: MM/dd/yyyy
4. go to Context and change the date context attribute to the created type.
sol2:
please try to minimize the casting between Date and String.
I believe in database date is stored as Date type itself. My suggestion will be for displaying keep a separate attribute and set it on each db call.
below code is converting from Date to String.
Date Sdate, Edate;
Sdate = rs.getDate ("Sdate");
Edate = rs.getDate ("Edate");
SimpleDateFormat date Formatter = new SimpleDateFormat ("MM/dd/yyyy");
String Sd = dateFormatter.format (Sdate);
String Ed = dateFormatter.format (Edate);
