Is there a way around this, like is there a quick function I can add that forces import range to update? I have already tried to add a wait

问题 I've written a script that utilizes Google's timed triggers. However, I'm having problems getting the script to fire at the correct time. I reside in Sydney (GMT +10) and need the script to fire at noon each day. I've gone in and set the timezone in the Spreadsheets settings, the Project Properties as well as the global settings for Google Drive but despite all this the script doesn't fire at the right time.

问题 How can I determine if something has changed in UPDATE trigger? For example I have table named person with only one column NAME which contains value 'Mike'. If I run UPDATE person SET NAME = 'Mike' how can I determine in the update trigger that nothing has changed? I know about UPDATE(col) statement, but I don't want to iterate over columns.

问题 I am trying to use PostgreSQL triggers in my rails app. So I tried using this migration where execution of triggers is supposedly easy: -- class AddTriggersToProducts < ActiveRecord::Migration def self.up table :products execute %q{ create trigger trig1 before insert on products for each row begin price = price + 5 end; } end def self.down execute 'DROP TRIGGER trig1' end end But this didn't change anything.

Similarly, you cannot declare triggers for an attached database (to do it the other way) unless you declare them
