Please forgive my inability to paste the actual code, but what he did was something Nope, (or ) is 's friend and always there as part of try/catch
However, it is perfectly valid to have them empty, like in your example In the comments in your example code (if func1 throws error, try func2), it would seem that what you really want to do is call the next function inside of the block of the previous. Finally and catch blocks are quite different Within the catch block you can respond to the thrown exception This block is executed only if there is an unhandled exception and the type matches the one or is subclass of the one specified in the catch block's parameter Finally will be always executed after try and catch blocks whether there is an exception raised or not.
Will return 1111 ever occur Set xact_abort on begin transaction begin. Catch will only run if an exception is thrown and the catch block can handle that type of exception The finally block is the one that will run when the try block is complete.
