MySQL JDBC 结果 尽管取得了更多成果,但下一个方法的回报却是无效的?
原标题:MySQL JDBC ResultSet next method returns null even though there are more results?

我有一份 Java申请,用一份声明来进行查询,以便归还大约100 000份记录。 我对ResultSet表示歉意,要求采用下一个方法检索每个记录。 我收到的记录数量各异。 没有任何例外,下一种方法根本无法恢复。

如何解释这种行为?

在黑暗中射出一枪:你是否一度从多个深层中 handling取/取用同一结果? 象同步问题一样,症状肯定会起作用。
