SQL Server Get Date: A Comprehensive Guide for Dev

Welcome, Dev, to our comprehensive guide on SQL Server Get Date. In this article, we will discuss everything you need to know about getting the system date and time in SQL Server. We will cover the basic syntax, different ways to retrieve the date and time, frequently asked questions, and much more.

Understanding SQL Server Get Date

SQL Server Get Date is a built-in function in Microsoft SQL Server that returns the current system date and time. It can be used to retrieve the current date and time for various purposes, such as auditing, logging, record keeping, and more. The Get Date function does not require any arguments or parameters and can be used in any query or stored procedure.

The basic syntax of SQL Server Get Date is as follows:

Function Name	Syntax	Description
Get Date	SELECT GETDATE()	Returns the current system date and time in the default format

Retrieving the Current Date and Time

To retrieve the current system date and time using SQL Server Get Date, you can simply use the SELECT statement followed by the function name as shown below:

SELECT GETDATE();

This will return the current system date and time in the default format of ‘YYYY-MM-DD HH:MI:SS’ (year-month-day hours:minutes:seconds). You can also use other date and time formats to display the result in different formats.

Retrieving the Current Date

If you only need to retrieve the current system date without the time, you can use the CAST or CONVERT function to cast the Get Date result to a date datatype as shown below:

SELECT CAST(GETDATE() AS DATE);

This will return the current system date in the format of ‘YYYY-MM-DD’ (year-month-day). You can also use the CONVERT function with a specific style parameter to display the result in different formats.

Retrieving the Current Time

If you only need to retrieve the current system time without the date, you can use the CAST or CONVERT function to cast the Get Date result to a time datatype as shown below:

SELECT CAST(GETDATE() AS TIME);

This will return the current system time in the format of ‘HH:MI:SS’ (hours:minutes:seconds). You can also use the CONVERT function with a specific style parameter to display the result in different formats.

Retrieving the Current Year

If you only need to retrieve the current year from the system date and time, you can use the YEAR function as shown below:

SELECT YEAR(GETDATE());

This will return the current year as a four-digit integer (e.g., 2022).

Different Ways to Retrieve the Date and Time

SQL Server provides various ways to retrieve the date and time based on your requirements. Here are some of the commonly used methods:

System Date and Time

The simplest and most straightforward way to retrieve the system date and time is by using the SQL Server Get Date function as shown earlier.

UTC Date and Time

If you need to retrieve the Coordinated Universal Time (UTC) date and time instead of the local date and time, you can use the UTC Get Date function as shown below:

SELECT GETUTCDATE();

This will return the current UTC date and time in the default format of ‘YYYY-MM-DD HH:MI:SS’ (year-month-day hours:minutes:seconds).

Date and Time from Different Time Zones

If you need to retrieve the date and time from a specific time zone other than the local time zone, you can use the SWITCHOFFSET function as shown below:

SELECT SWITCHOFFSET(GETDATE(), '-10:00');

This will return the current system date and time adjusted to 10 hours behind Coordinated Universal Time (UTC-10:00). You can replace the ‘-10:00’ with any valid time zone offset to retrieve the date and time from that time zone.
