Question

There are three ways to remove the time part of a datetime in SQL Server:

Use the DATE data type

The DATE data type only stores the date part of a datetime value. To use the DATE data type, you need to cast the datetime value to DATE. For example, the following code will remove the time part of the datetime value 2023-07-12 08:00:25:

SQL

SELECT CAST('2023-07-12 08:00:25' AS DATE);

Use the CONVERT function

The CONVERT function can be used to convert a datetime value to a different data type. To remove the time part of a datetime value, you can use the CONVERT function to convert the datetime value to the DATE data type. For example, the following code will remove the time part of the datetime value 2023-07-12 08:00:25:

SQL

SELECT CONVERT(DATE, '2023-07-12 08:00:25');

Use the SUBSTRING function

The SUBSTRING function can be used to extract a substring from a string. To remove the time part of a datetime value, you can use the SUBSTRING function to extract the first 10 characters from the datetime value. The first 10 characters of a datetime value represent the date part of the datetime value. For example, the following code will remove the time part of the datetime value 2023-07-12 08:00:25:

SQL

SELECT SUBSTRING('2023-07-12 08:00:25', 1, 10);

The best way to remove the time part of a datetime in SQL Server depends on your specific needs. If you need to store the date part of the datetime value in a separate column, you can use the DATE data type. If you need to store the date part of the datetime value in the same column, you can use the CONVERT function or the SUBSTRING function.
