Using TRY…CATCHThe following example shows a SELECT statement that will generate a divide-by-zero error. Client Code Yes, you should have error handling in client code that accesses the database. Here is how a CATCH handler should look like when you use error_handler_sp: BEGIN CATCH IF @@trancount > 0 ROLLBACK TRANSACTION EXEC error_handler_sp RETURN 55555 END CATCH Let's try some test Join them; it only takes a minute: Sign up Here's how it works: Anybody can ask a question Anybody can answer The best answers are voted up and rise to the navigate here
Not sure if this would help your retry logic, but to capture either info or errors for logging, I came up with something like this... Alternatively, the stored procedures or triggers can contain their own TRY…CATCH constructs to handle errors generated by their code. I highly recommend to you Mr. If your intention is to read it all, you should continue with Part Two which is where your journey into the confusing jungle of error and transaction handling in SQL Server https://msdn.microsoft.com/en-us/library/ms190358.aspx
You can find more information at http://www.rhsheldon.com. Typically, your CATCH rolls back any open transaction and reraises the error, so that the calling client program understand that something went wrong.

If your procedure does not perform any updates or only has a single INSERT/UPDATE/DELETE/MERGE statement, you typically don't have an explicit transaction at all. https://technet.microsoft.com/en-us/library/ms179495(v=sql.105).aspx Better than starting a separate process.

If two topological spaces have the same topological properties, are they homeomorphic? But as I mentioned earlier, the rules that govern RAISERROR are a bit quirky. Now few words about Shailendra Chauhan, he is very experienced and technically strong, he is providing the best project based training after discussing the concepts and real word examples after that
Until then, stick to error_handler_sp.
