Hello and welcome to this journal article on SQL Server Get Date Without Time. In this article, we will cover everything you need to know about getting the date without the time in SQL Server. We will explain what the date format is, and how to convert it to a datetime data type. We will also provide sample code and answer frequently asked questions (FAQs) about getting the date without time in SQL Server.
What is the Date Format in SQL Server?
The date format in SQL Server is YYYY-MM-DD. This means that the year comes first, followed by the month and then the day. For example, January 1st, 2022 would be represented as ‘2022-01-01’.
Converting Date to Datetime Data Type
To get the date without the time, we need to convert it to a datetime data type. The datetime data type in SQL Server includes both the date and the time. We can use the CONVERT function to convert the date to a datetime data type.
Here is an example code to convert the date to a datetime data type:
SELECT CONVERT(datetime, '2022-01-01')
This code will return ‘2022-01-01 00:00:00.000’, which includes the time as well. To get the date without the time, we need to use the CAST function.
Getting Date Without Time Using CAST Function
The CAST function is used to convert one data type to another in SQL Server. To get the date without the time, we can use the CAST function to convert the datetime data type to a date data type.
Here is an example code to get the date without the time using the CAST function:
SELECT CAST(GETDATE() as date)
This code will return the current date without the time.
Using a User-Defined Function to Get Date Without Time
We can also create a user-defined function to get the date without the time in SQL Server. Here is an example code to create a user-defined function:
CREATE FUNCTION GetDateWithoutTime (@date datetime)
RETURNS date
AS
BEGIN
RETURN CAST(@date as date)
END
This code will create a user-defined function called ‘GetDateWithoutTime’. We can call this function by passing a datetime value to it, and it will return the date without the time.

A: Yes, you can use the user-defined function to get the date without the time for multiple dates by passing a datetime value to it.
Conclusion
In conclusion, getting the date without the time in SQL Server is a simple process. We can use the CAST function, the CONVERT function, or create a user-defined function to get the date without the time.
