SQL Server: How do get only Date from Datetime?

Hi,
In real time business applications, we'll meet some scenarios like this. From our UI we'll send the Date time to the SQL Server to calculate the exact number of days different between today and the date passing by us.
Actually the GETDATE() function of SQL Server gives the Server's Date time in this format: 2011-01-26 11:43:13.397
The Date time sending from client UI will be like this: 2011-01-02 12:00:00.000

When we try to calculate the exact number of days different between these it'll take time too. This may be give wrong answer. In this situation we can ommit the time part of the both dates.
Here I wrote one SQL Server User Defined Function to achieve this.
CREATE FUNCTION [dbo].[UFN_GetExactDate] (@InputDate DATETIME)
RETURNS DATETIME

BEGIN
DECLARE @OutputDate DATETIME
SELECT @OutputDate= CAST(CONVERT(VARCHAR(25),@InputDate,101) AS DATETIME)
RETURN @OutputDate
END
We can use this UDF in our Stored procedures like this: SELECT [dbo].[UFN_GetExactDate](GETDATE())
This will give result like this: 2011-01-26 00:00:00.000

Hope this helps!

Javascript - Unanswered questions - Part 1

What is Event delegation? Event delegation is Javascript as it relates to the DOM. It basically means that if you attach an event listener to a DOM element that listener is not only firing on that DOM element. It's actually firing on every children in that. So, for instance if you have a navigation and so you've got an unordered list you've got list items and then you've got anchor tags inside that navigation what you have. If you add an event listener to the ul element in essence you're actually adding event listener to all of the children as well. In short, JS event listeners fir not only on a single DOM element but on all its descendants. What is Event Bubbling? It's actually inverse of Event delegation. Also known as propagation, events on an DOM element will bubble up and also fire on all parents. What's the difference between "target" and "currentTarget"? target is the actual element that triggered the event for example clicked, wh

Microservices vs. APIs

It still surprises me just how many times I come across misconceptions around Micro Services and APIs. Often hearing phrases like micro services are fine grained web services or API is themselves are equivalent to micro services. These all sort of show fundamental misconceptions under the covers. So, I've written this just to really break that out and explain about what the key differences are in those two concepts. What is an API? An API, fundamentally Application Programming Interface, that is an interface. It's a way of making requests into a component. So it's the route that you go in to make those requests. In modern use that typically means a REST API, that's a call made using HTTP protocol using JSON data as the payload. What are Micro Services? So let's ensure we also have a clear crisp definition on what a micro service architecture really is. Micro-Services architecture is about breaking down large silo applications into smaller components. That are more m
