为什么我得到ResultSet是闭合的错误，当我从来没有关闭任何 [英] Why am I getting ResultSet is closed error when I never closed any

问题描述

我在我的代码中有这个错误，并检查和编辑它彻底，但我仍然得到同样的问题。我也使用多个resultSet和语句，但同样的错误发生。下面是我得到的错误：

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？我现在不知道任何解决方案。

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

推荐答案

异常 java.sql.SQLException：ResultSet已关闭表示您的代码已关闭您正在使用的结果集对象
，或更可能的是您的代码已重新执行或关闭语句
产生结果集。根据JDBC规范，这些操作将从语句中关闭任何
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.
