  5. If calls stored procedures or invokes triggers, any error that occurs in these will also transfer execution to the CATCH block.
  6. Always rolling back the transaction in the CATCH handler is a categorical imperative that knows of no exceptions.
  7. These functions make it possible to create a friendly error and raise that (using raiserror) so that the client application doesn't get the default SQL error messages.
  8. As you see the TRY block is entered, but when the error occurs, execution is not transferred to the CATCH block as expected.
  9. So, there is no generic way to write isAssignable as try a=b; return true; catch return false; end; Posted by David Walker on 20 May 2011 sam.mesh: There's not a generic
