    Over the past few weeks, some readers have reported problems with sql error handling. The form of an error during program execution is often called an exception, and the mechanism for resolving such an exception is called exception handling. This article will show you how to enable them to implement exception handling in SQL Server. SQL Server provides TRY and CATCH objects for exception handling.

    How do you handle errors in PL SQL?

    Runtime errors arise from design errors, coding errors, large bugs, and many other sources. While you can’t anticipate every possible error, you can certainly plan to handle certain types of errors that are relevant to our PL/SQL program.

    How do you handle errors in SQL?

    Errors when using SQL Server eliminate Transact-SQL code. For example, if something goes wrong, people have the opportunity to do something about it and maybe put the house in order. Troubleshooting SQL Server errors can be as simple as logging that something has happened or that the software is trying to fix a bug. In fact, the error can be translated into SQL terminology, because we all know how meaningless and difficult to understand error messages from a SQL Server program can be. Fortunately, we have a real chance to translate these messages into a more meaningful message for users, developers, etc.

    Creating Custom Error Messages In SQL

    Sometimes we need to make sure you create custom error messages. They are usually intended for scenarios in which most of us, who knows, might have a problem. We can create our own messages that something went wrong without showing any technical details. For this, we use some keyword THROW.

    Why Should We Handle Errors?

    Why should we have error handling in our code? There are several reasons. In the developed application, we check the knowledge of users and notify users of individual errors. These user errors are assumed to be error-free. But we also need a way to handle unexpected errors. That is, errors that occur due to the fact that we missed one of them when writing the code. A simple strategy is to stop using it, or at least return to the point where my wife and I are in complete control. It cannot be overstated that ignoring an uncontrolled error is absolutely unacceptable. This is a sin that will certainly have serious consequences: it can cause the application to provide incorrect related information to the user, or even leave serious errors in the database. It’s also important to say that an error occurred so that the user doesn’t have to think where the operation went wrong, when in fact your code didn’t execute anything.So that it can be found.

    Rollback A Transaction In Case Of An Error/exception:

    Now look at how you can afford to rollback a transaction if an error or exception occurs. I am using the AdventureWorks database to test the following demo. I’m trying to delete data in a transaction that can no longer be deleted due to a reference constraint conflict, which is causing an exclusive error.

    What Exception Does SQL Server Handle?

    Some of the errors are currently generated by the application at runtime. These errors can be easily generated due to various applications and the application is unable to handle these errors causing the entire program to crash and a large exception being thrown.
