How to get the current date and time in SQL Server?

In SQL Server, you can use the built-in `GETDATE()` function to retrieve the current date and time. Here is an example:

SELECT GETDATE() AS CurrentDateTime;

The above query will return a result set containing the current date and time, with ‘CurrentDateTime’ as the alias for the column. You can customize the column name or further manipulate this result as needed.

Additionally, there are other functions related to dates and times that can be used to retrieve specific date or time information, such as `CURRENT_TIMESTAMP`, `SYSDATETIME()`, `SYSDATETIMEOFFSET()`, etc. The choice of which function to use depends on the precision and format of the information you want to retrieve.
