What Data Type Is Getdate () SQL?

The Getdate() function is a built-in date function in SQL that returns the current date and time of the system where the SQL Server is running. When using this function, it’s important to understand the data type that it returns.

Data Type

The Getdate() function in SQL Server returns a value of data type Datetime. This data type represents a date and time value from January 1, 1753, through December 31, 9999, with an accuracy of three-hundredths of a second.

The Datetime data type is made up of two parts: the date part and the time part. The date part represents the calendar date in year-month-day format, while the time part represents the time of day as hours:minutes:seconds with fractions of a second.

Usage Example

To better understand how to use the Getdate() function and its data type, consider the following example:

DECLARE @currentDateAndTime AS Datetime
SET @currentDateAndTime = Getdate()

SELECT 'The current date and time is: ' + CONVERT(VARCHAR(25), @currentDateAndTime)

In this example, we declare a variable called @currentDateAndTime with a data type of Datetime. We then use the Getdate() function to assign the current system date and time to this variable.

We can then use this variable in our SELECT statement to display a message along with the current date and time. The CONVERT() function is used to convert the Datetime value to a VARCHAR data type for concatenation with the message string.

Conclusion

In summary, the Getdate() function in SQL Server returns a value of data type Datetime, representing the current system date and time. Understanding the data type is essential when working with this function to ensure proper handling and manipulation of date and time values in SQL queries.
