You can make a (eventualy stored function) :
function IS_NUMBER (test_string IN VARCHAR2)
RETURN BOOLEAN
IS
test_value NUMBER;
BEGIN
test_value := TO_NUMBER (NVL(test_string,'0')); RETURN TRUE;
EXCEPTION
WHEN OTHERS
THEN
RETURN FALSE;
END IS_NUMBER; afterwards you can test it with IF IS_NUMBER(:block.textitem) THEN ....;
