Even worse, if there is no active transaction, the error will silently be dropped on the floor. Can an umlaut be written as line (when writing by hand)?

If there were two error messages originally, both are reraised which makes it even better. You can use ROLLBACK TRANSACTION to erase all data modifications made from the start of the transaction or to a savepoint.
This first article is short; Parts Two and Three are considerably longer. Recall that RAISERROR never aborts execution, so execution will continue with the next statement. For example, the following script shows a stored procedure that contains error-handling functions.
GO COMMIT TRANSACTION GO Even though the script results in an error, it never aborts to rollback. If we were to execute the SELECT statement again (the one in Listing 4), our results would look similar to those shown in Listing 7. In the second case, the procedure name is incorrect as well.

When a batch finishes, the Database Engine rolls back any active uncommittable transactions.

When is it okay to exceed the absolute maximum rating on a part? Rollback Transaction On Error In Informatica What you return does not really matter, as long as it's a non-zero value. (Zero is usually understood as success.) The last statement in the procedure is END CATCH. The default semantics are botched enough that you have to duplicate all this stuff. For the example, I will use this simple table.
This serves two purposes: 1) We can directly see that this is a message reraised from a CATCH handler. 2) This makes it possible for error_handler_sp to filter out errors it http://dba.stackexchange.com/questions/119517/forcing-ms-sql-server-to-rollback-on-error If an error occurs that has severity of 20 or higher and the database connection is not disrupted, TRY…CATCH will handle the error.Attentions, such as client-interrupt requests or broken client connections.When Set Xact_abort I guess that makes sense.

Yes, that is a situation that occurs occasionally, although you would typically do that in an inner CATCH block which is part of a loop.

In actually, I need only to roll back the transaction and specify the THROW statement, without any parameters.
Maybe you or someone else adds an explicit transaction to the procedure two years from now. This is great work. This asymmetry between COMMIT and ROLLBACK is the key to handling errors in nested transactions. In the first case, only the line number is wrong.
You may argue that the line IF @@trancount > 0 ROLLBACK TRANSACTION is not needed if there no explicit transaction in the procedure, but nothing could be more wrong. This is rather large change to the behavior of the call which has some serious implications to how exit handlers operate. And learn all those environments.
