SUMMARY
WAITFOR ERROREXIT is designed to wake up when a process is abnormally terminated. This does not include &quot;not found&quot; errors, syntax errors, RAISERROR, ARITHABORT, or even the killing of a process. An attempt to read a corrupted table will cause WAITFOR ERROREXIT to wake up. Basically, any error severe enough to cause a stack trace dump on the SQL Server will wake up WAITFOR ERROREXIT.

A process using WAITFOR ERROREXIT could be used to notify system administration personnel that an abnormal termination has taken place or perhaps perform some other action.

WAITFOR PROCESSEXIT wakes up whenever a client disconnects from the SQL Server. If the absence of a particular process signals some event, WAITFOR PROCESSEXIT could be used to wake up every time a process terminates, select SYSPROCESSES for a specific application name, and perform some action if it is not found. Another possibility is to check whether or not all users have logged off, and perform some action if they have.
