应用程序执行错误。
Return codes and SQLSTATE messages aid in diagnosing error conditions during the execution of an ODBC application.
返回代码和SQLSTATE消息可以帮助诊断odbc应用程序执行期间出现的错误状况。
For example, with the code that has been completed so far, if you enter a value of 0 in the first JSP page during execution, an error message will be generated on the application server console.
例如，使用前面已经完成的代码，如果您执行时在第一个jsp页面中输入值0，则将在应用程序服务器控制台上产生一个错误。
