Otherwise, a trap occurs for find, and the exception handler emits the standard file not found error.

Note that if no error handler is attached, the default implementation throws a SAXParseException on any validation error.
注意，如果没有指定错误处理程序，则默认的实现对任何验证错误都抛出SAXParseException异常。
The error handler, if one is provided, is the index on the stack of the Lua code to handle any errors that occur.

This is required if an unexpected error occurs and there is no fault handler specifically modeled to handle it.
如果发生意外错误，并且没有专门建模错误处理程序来处理该错误，则需要该操作。
Among other things, it defines a global error handler, and it is where you would place any platform-specific code to run before executing main application logic.
除了其他事情外，它定义一个全局错误处理程序，在此将放置在执行主应用程序逻辑之前要运行的特定于平台的代码。
Listing 13 demonstrates how a specific error can transfer control to the exit handler where a user-defined error message is returned depending on the value of the SQLCODE.
清单13展示了一个特定的错误如何将控制转移给退出处理程序，其中根据SQLCODE的值返回用户定义的错误消息。
When the INSERT statement fails with the error code specified in the DECLARE exit handler statement, control passes to the handler, and the procedure is exited.
