Check if block is emty

Question

Hello.
Is there a (short or simple) way to check, if the user has entered data into any item in a block, which is in enter-query mode?
Problem.
When the user executes query, i have to check, if he entered data in enter-query mode. If he entered search criteria, then the form executes query one way. When no data is entered, form executes query another way.
How do i check, if there is search criteria in any item in a block (and not using: if item1 is null and item2 is null and ...)?
Thanks.

could be use following, but i don't know if it go well for you:
Obtaining Query Count Without EXECUTE-ing a Query
FUNCTION query_count (p_block_name VARCHAR2) RETURN NUMBER
IS
cnt NUMBER;
BEGIN
GO_BLOCK(p_block_name);
COUNT_QUERY;
cnt := GET_BLOCK_PROPERTY(p_block_name, QUERY_HITS);
IF FORM_SUCCESS THEN
RETURN (cnt);
ELSE
MESSAGE('Error in getting Query Hits for block '||:SYSTEM.CURRENT_BLOCK);
RAISE FORM_TRIGGER_FAILURE;
END IF;
END;
WHEN-BUTTON-PRESSED trigger
DECLARE
v_cnt NUMBER;
BEGIN
v_cnt := query_count(<detail block name>);
IF (v_cnt = 0) THEN
p_show_alert('No Details exist.');
ELSE
GO_BLOCK(<detail block name>);
EXECUTE_QUERY;
END IF;
END;
