Hi DW. I'm a bit confused and lost on how this App is working called Ha Tunnel Plus (You can check it on Playstore, and have a look on YouTube for the configuration file).

## Introduction ## When localizing your application, `ResourceBundle` can be a great way to load Strings from different locales. The only concrete implementation of ResourceBundle is `PropertyResourceBundle`, which allows us to load static Strings from a text file. Because `.properties` is a common file extension used for ResourceBundles, creating ResourceBundle objects using this file format would be the focus of this tutorial. Property files are commonly used to load application properties for Spring Boot projects, so if you have been working with Spring Boot, then this file format should be familiar to you; the only difference to what we create …

Hello. I am trying to check if a table definition (the default value on a constraint) is equal to UTC Time by using the following query: IF NOT EXISTS((SELECT object_definition(default_object_id) AS definition FROM sys.columns WHERE name = 'ModifiedDate' AND object_id = object_id('dbo.WorkflowAudit')) == GETUTCDATE()) However, you can not compare a function (`GETUTCDATE()`) to this Select Statement. I need to do it this way because I am building an update script and it can only update the table IF the table definition is NOT equal to UTC TIME Any ideas? Thank you
