3 Effective Methods to Print Error Messages in SQL Server

If you’re involved in software development, understanding how to display error messages in SQL Server can be crucial. Fortunately, it’s quite straightforward. This article will guide you through several effective methods.

How to Display an Error Message in SQL?

1. Utilizing RAISERROR

1. First, access your configuration settings.
2. Insert the following command: RAISERROR('This is an alert message', 16, 1);
3. Ensure all changes are saved.

Now, let’s clarify the parameters involved. The message you provide is accompanied by the severity level, which is represented by the number 16. This level signifies a common user error. The final parameter, 1, points to a specific segment of the code or state.

This approach is quite simple and has proven effective, even in earlier versions of SQL Server prior to 2012.

2. Implementing THROW

1. Access your configuration settings.
2. Include this line of code: THROW 50000, 'This is an alert message', 1;
3. Don’t forget to save your changes.

This instruction applies to SQL Server 2012 and later. Now, let’s examine the parameters in detail.

The number 50000 serves as your error number, indicating that user-defined errors must be set to 50000 or greater. The last number, 1, signifies the state, similar to how it works with RAISERROR.

3. Using TRY CATCH

1. Open your code structure.
2. Next, insert the following code: BEGIN TRY -- Code that may result in an error SELECT 1 / 0; -- Example to trigger a division by zero errorEND TRYBEGIN CATCH PRINT 'Error Message: ' + ERROR_MESSAGE();END CATCH
3. Save the modifications.

This illustrates how to output error messages within the CATCH block of SQL Server, making it an excellent choice for debugging purposes. With this setup, anytime an error occurs, the function ERROR_MESSAGE() retrieves the corresponding error details.

As you can see, the process of displaying an error message in SQL Server is quite easy when you follow these guidelines.

Now that you are equipped with the knowledge of error handling, you can effectively address common issues, such as the 0x80040e14 SQL Server error and SQL Server error 18456.
