当我从未关闭任何内容时，为什么会收到 ResultSet is closed 错误

Why am I getting ResultSet is closed error when I never closed any(当我从未关闭任何内容时，为什么会收到 ResultSet is closed 错误)

问题描述

我的代码中有这个错误，并且已经彻底检查和编辑它，但我仍然遇到同样的问题.我还使用了多个 resultSet 和 Statements 但发生了同样的错误.以下是我得到的错误:

I have this error in my code and have checked and edited it thoroughly, yet I still get same issue. I also use multiple resultSet and Statements yet same error occurs. Below is the error I get:

    "Database Connected with Current Date 20130221
    java.sql.SQLException: ResultSet is closed
    at sun.jdbc.odbc.JdbcOdbcResultSet.checkOpen(Unknown Source)
    at sun.jdbc.odbc.JdbcOdbcResultSet.next(Unknown Source)
    at UNSUB.main(UNSUB.java:78)"
Press any key to continue . . .

请问可能是什么原因?我现在不知道有什么解决办法.

Please What could be the reason? I have no idea on any solution now.

推荐答案

异常，java.sql.SQLException: ResultSet is closed表示你的代码要么已经关闭了结果集对象您正在使用，或者更有可能，您的代码已经重新执行或关闭了以下语句产生了结果集.根据 JDBC 规范，这些操作中的任何一个都将关闭任何语句的结果集.

The exception, java.sql.SQLException: ResultSet is closed means that your code has either already closed the result set object you're using, or more likely, that your code has either re-executed or closed the statement that produced the result set. By JDBC specs, either of those actions will close any result set from the statement.
