Error Handling In Sql Server 2012

VALUES (myValues ...); INSERT INTO myTable (myColumns ...) VALUES (myValues ...); COMMIT TRAN; It is sent by one long string command. If one of the inserts fail, or any part of the command fails, does SQL Server roll back the transaction? If it does not sql server try catch transaction rollback, do I have to send a second command to roll it back? I can give specifics about the api and language I'm using, but I would think SQL Server should respond the same for any language. sql sql-server sql-server-2005 transactions share|improve this question edited Nov 17 '09 at 16:10 marc_s 454k938711033 asked Nov 17 '09 at 15:38 jonathanpeppers 14.9k1473157 stackoverflow.com/questions/1150032/… –zloctb Jul 7 '15 at 16:55 add a comment| 4 Answers 4 active oldest votes up vote 119 down vote accepted You can put set xact_abort on before your transaction to make sure sql rolls back automatically in case of error. share|improve this answer edited Mar 28 '12 at 21:37 Greg B 8,4491356106 answered Nov 17 '09 at 15:47 DyingCactus 23.8k24138 1 Will this work on MS SQL 2K and higher?

Implementing Error Handling with Stored Procedures in SQL2000. Why Error Handling? Why do we have error handling in our code? There are many reasons. In a forms application we validate the user input and inform the users of their mistakes. These user mistakes are anticipated errors. But we also need to handle unanticipated errors. That is, errors that occur because we overlooked something when we wrote our code. A simple strategy is to abort execution or at least revert to a point where we know that we have full control. It cannot be enough stressed that it is entirely impermissible to ignore an unanticipated error. This is a sin that can have grave consequences: i
