invoice_date - database item
My master and details relation is invoice_no and invoice_date
when button pressed trigger in search button is
declare
v_where_1 varchar2(10);
v_where_2 varchar2(10);
begin
v_Where_1 := ' invoice = '||:block_a.invoive_no;
v_where_2 := ' invoice_date = ' ||:block_a.invoive_date;
set_block_property('block_b', default_where, v_where_1|| 'and' || v_where_2);
go_block('block_b');----detailed block
execute_query;
end;
after pressing search button it clear invoice_date from master block

rdk,
try this
declare
v_where_1 varchar2(200);
v_where_2 varchar2(200);
QT VARCHAR2(10) :='''';
begin
v_Where_1 := ' invoice = '||QT||:block_a.invoive_no||QT; --- IF INVOICE_NO DATA TYPE IS CHAR/VARCHAR2
v_where_2 := ' invoice_date = ' ||QT||:block_a.invoive_date||QT;-- IF INVOICE_DATE DATA TYPE IS DATE
go_block('block_b');----detailed block
set_block_property('block_b', default_where, v_where_1|| ' and ' || v_where_2);
execute_query;
end;Hope this works....
