Adding additional contraints on a query.

Question

I have a normal datablock containing a 'description' field. I'd like to run a query on the same block but using an 'in description' parameter. Is it possible to change the default query for the block to something else containing this extra parameter?

It sure is possible to set any kind of where clause.
On a when-button-pressed trigger you may have somthing like this:
declare
strwhere varchar2(1000);
begin
str_where:='descriptor like '| |''''| |
:filter_block.descr_cond| |'%'| |'''';
-- eventually you may add whatever conditions you need
str_where:=str_where| |' and ...'
set_block_property('your_block', default_where, str_where);
go_block('your_block');
execute_query;
end;
