How to use last_query built in?

Question

Hi People
I would like to use last_query in order to obtain a query which is last executed.I used the following code to obtain the result.but i couldnt get it.i wrote this code in when-button-pressed trigger.
i.e,
declare
     lst_q varchar(2000);
     t varchar(2000);
begin
     lst_q:=get_block_property('block3',last_query);
     message(lst_q);
     end;
Is this a right way to use the last_query variable?.pls suggest me.thanku

Hai,
In the GET_BLOCK_PROPERTY, you can use LAST_QUERY as second parameter.
The GET_BLOCK_PROPERTY('<block_name>', LAST_QUERY) will return NULL if there is no query is executed before.
You can use like this.
DECLARE
     lst_q VARCHAR2(2000);
     t VARCHAR2(2000);
BEGIN
     lst_q := GET_BLOCK_PROPERTY('block3', LAST_QUERY);
     :block3.text_item7 := lst_q;
END;Regards,
Manu.
