[Database](https://www.mindstick.com/articles/12226/use-of-database-in-sencha-extjs-and-insert-record-from-user-form-using-ajax) related exceptions can be handled in [Entity](https://www.mindstick.com/forum/160562/database-connectivity-using-entity-framework-database-first-approach) [Framework](https://www.mindstick.com/forum/34615/software-framework-vs-library) Core by using try-catch blocks. In the following code, the DbUpdateException is caught and the message is printed to the console:

C#

```plaintext
try {
  context.SaveChanges();
} catch (DbUpdateException ex) {
  Console.WriteLine(ex.Message);
}
```

The message property of the DbUpdateException object contains a more detailed description of the error.

Here are some other common database related exceptions in Entity Framework Core:

- DbEntityValidationException: This exception is thrown when an entity fails validation.
- DbConnectionException: This exception is thrown when there is a problem with the database connection.
- DbCommandException: This exception is thrown when there is a problem with a database command.
- DbTransactionException: This exception is thrown when there is a problem with a database transaction.

To [handle](https://www.mindstick.com/articles/311004/suede-skillet-handle-cover) these exceptions, you can use the same try-catch blocks as for the DbUpdateException.

In addition to catching exceptions, you can also take steps to prevent them from happening in the first place. For example, you can validate your entities before saving them to the database. You can also use transactions to ensure that all of the changes to the database are committed or rolled back together.

By handling and preventing database related exceptions, you can ensure that your application is robust and reliable.

Here are some additional tips for handling database related exceptions:

- Log the exception message to a file or database. This will help you to track down the cause of the error.
- Retry the operation if the exception is transient. For example, if the database is unavailable, you can retry the operation a few seconds later.
- Display a friendly error message to the user. This will help the user to understand why the operation failed.

By following these tips, you can ensure that your application can handle database related exceptions gracefully.
