How to Get System Date in SQL Server Management Studio: An Overview

The following are different methods to obtain the system date in SQL Server Management Studio:

• GETDATE() function: Returns the current date and time based on the computer’s system date and time.
• CURRENT_TIMESTAMP function: Returns the current date and time of the server.
• SYSDATETIME() function: Returns the date and time of the server in the format YYYY-MM-DD HH:MI:SS.nnnnnnn.

Each of these methods has its own advantages and disadvantages. Depending on the requirements of your application, you can choose the method that works best for you.

Let’s take a closer look at each of these methods:

Using GETDATE() Function

GETDATE() is a built-in SQL Server function that returns the current system date and time. This function is commonly used to get the current date and time for various purposes.

To use the GETDATE() function, simply type it in your SQL query followed by parentheses, like this: SELECT GETDATE(). This will return the current date and time in the default format.

You can also format the date and time returned by the GETDATE() function using the CONVERT() function. This allows you to customize the date and time format to meet your specific requirements.

One important thing to note is that the date and time returned by the GETDATE() function is based on the system date and time of the computer running SQL Server. Therefore, if the system date and time are incorrect, the date and time returned by the function will also be incorrect.

How to Use GETDATE() Function to Get System Date?

To retrieve the system date in SQL Server Management Studio, you can use the built-in GETDATE() function. This function returns the current system date and time as a datetime value.

To use the GETDATE() function, simply call it in a SELECT statement:

• SELECT GETDATE();

Executing this statement will return the current system date and time in the format of datetime data type.

Using CURRENT_TIMESTAMP Function

If you want to get the current system date and time in SQL Server, you can use the CURRENT_TIMESTAMP function. This function returns the current date and time in the default format. It is similar to the GETDATE() function, but with more precision.

The CURRENT_TIMESTAMP function is a built-in function in SQL Server, which means that it can be used without any additional setup or configuration. This function returns a datetime data type that includes both the date and time.

One advantage of using the CURRENT_TIMESTAMP function is that it returns the date and time in Coordinated Universal Time (UTC) format, which is the standard international time format.

To use the CURRENT_TIMESTAMP function, you simply need to call it in your SQL query. For example, if you want to retrieve the current system date and time, you can use the following query:

SELECT CURRENT_TIMESTAMP;

This will return the current system date and time in the default format. If you want to format the output differently, you can use the CONVERT function with the appropriate style code.

How to Use CURRENT_TIMESTAMP Function to Get System Date?

The CURRENT_TIMESTAMP function can be used to retrieve the current system date and time in SQL Server Management Studio. Here’s how:

Using SELECT Statement: To retrieve the current date and time using the CURRENT_TIMESTAMP function, execute the following SQL statement: SELECT CURRENT_TIMESTAMP;

Using INSERT Statement: You can also use the CURRENT_TIMESTAMP function to insert the current date and time into a table. Here’s an example: INSERT INTO my_table (my_date) VALUES (CURRENT_TIMESTAMP);

Using UPDATE Statement: If you want to update a table with the current date and time, you can use the CURRENT_TIMESTAMP function with an UPDATE statement. Here’s an example: UPDATE my_table SET my_date = CURRENT_TIMESTAMP WHERE id = 1;

By using the CURRENT_TIMESTAMP function, you can ensure that your database always has the accurate system date and time. This can be useful for tracking events or for ensuring that time-sensitive data is properly recorded. In the next section, we will discuss another way to get system date in SQL Server Management Studio.

Using SYSDATETIME() Function

The SYSDATETIME() function is used to return the system date and time in SQL Server Management Studio.

Unlike other date and time functions, SYSDATETIME() returns a datetime2 value that includes fractional seconds with a precision of 100 nanoseconds.

When a user executes the SYSDATETIME() function, it returns the current system date and time in UTC (Coordinated Universal Time).

Since SYSDATETIME() returns a datetime2 value, it can be used to perform various mathematical operations with date and time values.

When you want to use the system date and time in a SQL query, SYSDATETIME() is a very useful function to have in your toolkit.

How to Use SYSDATETIME() Function to Get System Date and Time?

The SYSDATETIME() function is used to get the system date and time in SQL Server Management Studio. It returns a datetime2 data type value that represents the current date and time of the system on which the SQL Server instance is running.

The following is the syntax to use the SYSDATETIME() function:

Syntax	Description
SYSDATETIME()	Returns the current date and time of the system on which the SQL Server instance is running in the datetime2 data type.

The returned datetime2 value is in the format of ‘YYYY-MM-DD HH:MI:SS.nnnnnnn’, where ‘nnnnnnnn’ represents the fractional seconds up to seven decimal places.

The SYSDATETIME() function is useful in scenarios where high-precision date and time values are required, such as in financial applications or in scientific research. It is also useful for auditing and tracking changes to data, as it provides a precise timestamp of when the change occurred.

Difference Between SYSDATETIME() and GETDATE() Functions

SYSDATETIME() and GETDATE() are both functions used to get system date and time in SQL Server Management Studio. However, there are some differences between these two functions.

The first difference is the level of precision. SYSDATETIME() provides more precise results, up to nanoseconds, while GETDATE() provides results up to one-third of a second.

The second difference is that SYSDATETIME() returns a datetime2 data type, which requires more storage space compared to the datetime data type returned by GETDATE().

Finally, SYSDATETIME() is a nondeterministic function, meaning that each time it is executed, it may return a slightly different value. GETDATE(), on the other hand, is a deterministic function, meaning that it always returns the same value when executed multiple times within the same statement.

Using GETUTCDATE() Function

Overview: The GETUTCDATE() function is used to get the current UTC date and time in SQL Server Management Studio. UTC stands for Coordinated Universal Time, which is a standardized time system used across the world.

Usage: The GETUTCDATE() function is used similarly to other date and time functions in SQL Server Management Studio. It does not take any parameters and simply returns the current UTC date and time.

Benefits: One of the main benefits of using GETUTCDATE() function is that it provides a standardized time system that is not affected by time zone changes or Daylight Saving Time adjustments. This makes it useful in situations where accuracy and consistency are critical, such as in financial transactions or in distributed systems that operate across different time zones.

Limitations: One limitation of using GETUTCDATE() function is that it returns the current UTC date and time, which may not be the same as the local date and time of the user or system. This means that additional calculations may be required to convert the UTC time to the local time if needed.

Example: The following example demonstrates how to use the GETUTCDATE() function to get the current UTC date and time:

SELECT GETUTCDATE() AS 'Current UTC Date and Time' 

This query will return a result similar to the following:

Current UTC Date and Time -------------------------- 2023-03-30 07:45:32.953 

How to Use GETUTCDATE() Function to Get System Date and Time in UTC?

The GETUTCDATE() function in SQL Server is used to return the current system date and time in UTC time zone. It is similar to the SYSDATETIME() function, but the difference is that it returns the date and time in UTC time zone.

To use the GETUTCDATE() function, simply call the function without any parameters:

SELECT GETUTCDATE();

This will return the current system date and time in UTC time zone.

It’s important to note that the GETUTCDATE() function is not affected by the time zone setting of the server. It always returns the system date and time in UTC time zone, regardless of where the server is located.

Advantages of Using GETUTCDATE() Function Over Other Date Functions

Accuracy: The GETUTCDATE() function returns the current UTC date and time accurately, which is essential in applications that need precise time measurements, such as financial transactions and stock trading.

Consistency: Since UTC is a universal time standard, using GETUTCDATE() ensures consistency in date and time calculations across different time zones, servers, and databases. This consistency eliminates confusion and avoids errors that may result from using local date and time functions.

Flexibility: GETUTCDATE() can be easily converted to any time zone using the built-in functions. For instance, CONVERT() function can be used to convert UTC to a specific time zone. This flexibility ensures that applications can cater to users in different regions without any issues.

Conclusion

SQL date functions are essential for developers to manipulate dates and times in SQL queries.

GETDATE(), CURRENT_TIMESTAMP, SYSDATETIME(), and GETUTCDATE() are some of the most commonly used date functions in SQL.

Each function has its unique features, and the developer should use the appropriate function based on the requirement.

By using these functions, developers can efficiently perform various date and time operations, including date manipulation, date formatting, and time zone conversions.

Summary of Different Ways to Get System Date in SQL Server Management Studio

SQL Server Management Studio provides several ways to get the system date and time. The most commonly used functions are GETDATE(), CURRENT_TIMESTAMP, SYSDATETIME(), and GETUTCDATE().

GETDATE() function returns the current local system date and time. CURRENT_TIMESTAMP function is equivalent to GETDATE() function and returns the current date and time of the local system.

SYSDATETIME() function returns the current system date and time with high precision. GETUTCDATE() function returns the current UTC system date and time.

Choosing the right function depends on the precision and time zone required for the application. Use GETDATE() or CURRENT_TIMESTAMP functions for simple date and time operations. Use SYSDATETIME() function for high precision and GETUTCDATE() function for UTC time zone operations.

Which Function to Choose for Getting System Date and Time?

If you’re working on a software project that requires accurate date and time information, you may be wondering which function to use for getting the system date and time. The two most commonly used functions for this purpose are Date() and Time().

The Date() function is used to retrieve the current date, including the year, month, and day. It is often used in conjunction with other date-related functions, such as getFullYear(), getMonth(), and getDate(), to extract specific date components. On the other hand, the Time() function is used to retrieve the current time, including the hours, minutes, seconds, and milliseconds. It can also be used with other time-related functions, such as getHours(), getMinutes(), and getSeconds(), to extract specific time components.

Choosing the right function for your needs depends on the specific requirements of your project. If you need to work with both date and time information, you can use the Date() and Time() functions together. Alternatively, if you only need to work with one or the other, you can use the appropriate function to avoid unnecessary code bloat.

It’s also worth noting that different programming languages and frameworks may have their own built-in functions for retrieving date and time information. For example, the Python programming language has a built-in datetime module that provides a variety of functions for working with dates and times. Similarly, the popular JavaScript library Moment.js provides a comprehensive set of date and time manipulation functions.
