Execute query not give result

Question

Hi master
Sir lets suppose I have emp form and I put under blow code in when button press event
When_Button_press
go_block('emp');
enter_query;
:emp.deptno := 10;
execute_query;
but
when I press button then no result no data in any field and curser present in first column or form.

:emp.deptno := 10;
execute_query;
system not replace data and no run execute_query
please give me idea

Hi master
Sir when I use this code with numeric data work fine
DECLARE
     DD VARCHAR2(15);
BEGIN
     DD:=10;
set_block_property('emp', default_where, 'where
DEPTNO='||DD);
go_block('emp');
execute_query;
set_block_property('emp', default_where, '');
END;
But When use with string data then not give result I
press f8 and show all record
With character not give any result
DECLARE
     DD VARCHAR2(15);
BEGIN
     DD:='SALESMAN';
set_block_property('emp', default_where, 'where
RTRIM(EMPNO)='||DD);
go_block('emp');
execute_query;
set_block_property('emp', default_where, '');
END;
Please give me any ideaYour problem is in your where clause you do not put the word where in the where clause as it is assumed
I usually declare a variable v_where VARCHAR2(200);
and then assign it my new where clause
v_where := ' RTRIM(EMPNO)='||DD;
GO_BLOCK ('emp');
SET_BLOCK_PROPERTY('emp',default_where, v_where);
EXECUTE_QUERY;
v_where := null; ---clean up
This allows you to easily put your where clause into a message
message(v_where);
so you can see what is really being queried. This is very useful when you are using multiple values to make sure you have all the apostrophes that you need
eg: v_where := v_where := 'item_type <> ''CAT'''||' and user_id = '''||:login.user_id||'''';
