Consider a scenario wherein you are doing some operation which is generatingError Severity 16 State 1
an error with Level\Severity 16 and is causing the entire transaction to error 3041 severity 16 fail with the following message: Msg 3998, Level 16, State 1, Line 1 Uncommittable transaction is detected at
Error 55555 Severity 16
the end of the batch. The transaction is rolled back. Alternatively, you may see errors like the following which will rollback entire transaction: Msg 8169, Level 16, State 2, Line error 18210 severity 16 5 Conversion failed when converting from a character string to uniqueidentifier. Note: There are several more errors that could fail with Level\Severity 16. You may want to argue as to why the Severity 16 error message terminates the entire transaction and not continue with the batch. And I would say it depends! Typically, the function which decides whether the transaction would error 18210 severity 16 state 1 operating system error 995 get into doomed state or not is called as XACT_STATE(). This function is a scalar function that reports the user transaction state of a current running request. XACT_STATE indicates whether the request has an active user transaction, and whether the transaction is capable of being committed. As per Books Online, this functions returns following three values: 1, 0 or -1. XACT_STATE() = -1 means that the current request has an active user transaction, but an error has occurred that has caused the transaction to be classified as an uncommittable transaction. When a batch finishes running, the Database Engine will automatically roll back any active uncommittable transactions. The request cannot perform any write operations until it rolls back the transaction. The request can only perform read operations until it rolls back the transaction. As per our intensive research we asserted that XACT_STATE changes is not governed by a single rule and depends on the transaction state (user or system initiated and if an active transaction or not) and the type of error being raised. For example, transactions having CONVERT\CAST errors and DDL

of Errors and severity level in SQL Server with catalog view sysmessages Few days back I have written “Error handling with “THROW” command in SQL Server 2012”. After reading this article, one of the regular http://blog.extreme-advice.com/2013/01/29/list-of-errors-and-severity-level-in-sql-server-with-catalog-view-sysmessages/ blog readers has asked me question why I have used 16 severities for the error? This is really interesting question so I thought to answer him in the form of this blog post so that everyone who is unaware with error messages in SQL Server can be benefited. 16 is a default severity level and used for most user exception and that was the reason I have used it. severity 16 You can get a list of error messages along with its severity level and error number from following catalog view. SELECT * FROM master.dbo.sysmessages WHERE error=8134 -- error message number I got in previous article AND msglangid = 1033; --language selection, 1033 represents US english There are total number of 10542 error message comes by default for language id 1033 (US English). Error messages given in total severity 16 state 22 language so 10542 error * repeated 22 times = 231924 rows in sysmessages. Generally we have sixteen different severity level in SQL Server 2012 and each severity represents criticalness of an error. You can get a list of severity from the following TSQL. SELECT DISTINCT severity FROM master.dbo.sysmessages; Here is the brief description of different severity. Severity level 0-10: These are just information message not actual error. Severity level 11 to 16: These are errors caused due to user mistakes. We have tried to divide value by 0 in previous article and hence we got severity error 16. Severity Level 17: This severity indicates that an operation making SQL Server out of resources or exceeding defined limit. That may be disk space or lock limit. Severity Level 18: This error represents nonfatal internal software error. Severity Level 19: This error represents some non-configurable internal limit has been exceeded and the current batch process is terminated. To be very frank, I have not seen this severity practically in my life. Severity Level 20: This severity indicates current statement has encountered a problem and because of this severity level client connection with SQL Server will be disconnected. Severity Level 21: This severity indicates that
