Why am I getting ResultSet is closed error when I never closed any

问题

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 . . .

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

回答1:

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.

Have you called the method next() on the ResultSet?? If you haven't that might be the reason for you to get that error.
