The conversion of a datetime2 data type to a datetime data type resulted in an out-of-range value
🚀 Solving the "Conversion of datetime2 data type to datetime data type resulted in an out-of-range value" Error
Are you getting a headache trying to figure out why you're seeing the dreaded "Conversion of datetime2 data type to datetime data type resulted in an out-of-range value" error? Don't worry, I've got your back! In this blog post, I'll explain what causes this error and provide you with easy solutions to fix it. Stick around till the end for a special surprise 😉.
Understanding the Problem
When you encounter this error, it means that you are trying to convert a value of the datetime2 data type to the datetime data type, but the value is out of range. In your case, it appears to be related to the Edit method in your HomeController.
Exploring the Code
Let's dive into your code to understand where the issue might be coming from. In your HomeController, we can see two overloaded Edit methods. The first one retrieves an article to edit using LINQ, while the second one handles the HTTP POST request.
In the first method, you fetch the
ArticleToEditusing LINQ and pass it to theView.In the second method, you receive an
Articleobject as a parameter. You then fetch the original article from the database and perform some validation before saving the changes.
Identifying the Root Cause
Based on the error message and your code, the most likely cause of the issue is related to the Article object's properties, specifically one that holds a datetime value. It seems you are updating the ArticleToEdit object's properties when saving changes to the database.
Solving the Problem
There are a few things you can do to fix this error:
1. Check the DateTime Properties
Inspect your Article model and make sure that all properties with datetime values are valid and within the range accepted by the datetime data type. Look out for any properties that might have incorrect or out-of-range values. Double-check how you are setting these properties in your view.
2. Validate the ModelState
In your second Edit method, you have a validation check using ModelState.IsValid to ensure the data is valid before saving. This is great! However, it's worth re-evaluating your validation logic to ensure it covers all necessary validations, including datetime properties.
3. Examine the View
Take a close look at the view associated with the Edit method. The error message you received doesn't mention anything about dates, but it's possible that a date-related issue is occurring behind the scenes. Check all date-related inputs (TextBox, TextArea, etc.) and make sure their values are correctly mapped to the Article model properties.
4. Double-Check Database Structure
In some cases, this error can stem from differences between the database schema and the model. Verify that the data type for date-related fields in your database matches the data type (datetime2 or datetime) expected by your model.
5. Upgrade Database Providers
If you're using Entity Framework with a database provider, check for any available updates for both Entity Framework and the database provider. Sometimes, these updates include bug fixes related to data type conversions.
Time to Take Action!
Now that you have a clearer picture of what might be causing the error and potential solutions, it's time to put your troubleshooting skills to the test. Try the suggested solutions one by one, and hopefully, you'll soon bid farewell to the annoying "Conversion of datetime2 data type to datetime data type resulted in an out-of-range value" error!
