Hi
The datablock have their own insert and query using thru commit_form.

The same, can delete using thru commit_form without explicitly using delete statement. But I fix the record which want to delete.

This is how I would do that:
- enter query mode
- select "statecode" from list of values
- execute query
- delete a record which is displayed as a result of query operation
- commit

Hi Littlefoot,
As you said i feel i done. check Weather it is correct or not
to achieve my work.

On Delete Button(when_button_pressed)

:Global.Mode := 'DELETE';
go_item('Statecode');

On Statemaster Block(when_new_block_instance)

If :Global.Mode = 'QUERY' Then
	  Execute_query;
End If;

If :Global.Delete = 'DELETE' Then
	  Enter_Query;	  
End If;

On Statecode Item (Key_next_item)

If :Global.Mode = 'DELETE' Then
	 Set_block_property('statemaster', default_where, 'statecode = ' || :Statecode);
	 Execute_Query;
End If;

It fetches all the records from the table instead of selected one.

I'd rather say "all records from a table whose STATECODE column equals :STATECODE form item's value".

If there are too many records and you need only one of them, you'll have to further restrict fetched data set by including additional condition into the DEFAULT_WHERE clause.

If that's mapped to "delete record", yes.

Yes, in order to save the changes.
