java.sql.SQLException

Question

I am getting the following error:

java.sql.SQLException: Exhausted Resultset
    at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:134)
    at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:179)

    at website.web.InboxReader.accessGmail(InboxReader.java:122)
    at website.web.InboxReader.main(InboxReader.java:51)

after these lines:

    ResultSet parentMessage = parentstmt.executeQuery("SELECT SUM(IMPORTANCE) AS IMPAVG FROM MAIL");
    avgsum = parentMessage.getFloat("IMPAVG");

Am I not doing the above correctly?

Thanks!

try calling

parentMessage.next();
