What is Date Formatting?
Before we dive into the different ways to format dates in SQL Server, let’s discuss what date formatting is. Date formatting is the process of converting a date into a specific format. This is usually done to make the date more readable or to match a specific format requirement. SQL Server has several built-in functions that can help you format dates. We will be discussing these functions in the following sections.
FAQs
| Question | Answer |
|---|---|
| What is the date format in SQL Server? | The date format in SQL Server is yyyy-mm-dd. |
| Can I change the date format in SQL Server? | Yes, you can change the date format in SQL Server using the CONVERT function. |
| What is the difference between the CONVERT and CAST functions? | The CONVERT function allows you to convert a data type to another data type with a specific format. The CAST function only allows you to convert a data type to another data type without any formatting. |
Basic Date Formatting
The most basic way to format a date in SQL Server is to use the CONVERT function. The CONVERT function allows you to convert a date into a specific format. Here is a basic example:
SELECT CONVERT(VARCHAR(10), GETDATE(), 101)
In this example, we are using the GETDATE function to get the current date and time. We are then using the CONVERT function to convert the date into a VARCHAR data type with the format mm/dd/yyyy. The result will be something like this:
| 02/20/2022 |
As you can see, the date is now in the format we specified.

Advanced Date Formatting
If you need to format a date in a more complex way, you can use the FORMAT function. The FORMAT function allows you to format a date using a custom format string. Here is an example:
SELECT FORMAT(GETDATE(), 'dddd, MMMM dd, yyyy')
In this example, we are using the GETDATE function to get the current date and time. We are then using the FORMAT function to format the date using a custom format string. The result will be something like this:
| Saturday, February 19, 2022 |
As you can see, the date is now in a custom format that we specified.
