java.sql.SQLException: 结果集已耗尽
高朝明
2013年10月21日 星期一 21时43分23秒
说明： 继上次的java.sql.SQLException: ORA-01013: user requested cancel of current operation 错误。查了两天也没查出具体原因。后在同事的建议下，延长查询时间。因为生产库不能随意重启，
于是就写了个testQuery.jsp测试页面来测试生产环境中延长脚本查询时间是否可以完全生成文件并导出：

页面测试开始......
查询开始时间:2013-27-21 1124:27:05
查询结束时间:2013-27-21 1124:27:24
写完Excel时间:2013-27-21 1124:27:24
下载访问路径:http://localhost:7001/CTCB/web/CB/test.xls
测试结果发现：第二个查询结果最长也才用了20s而已。而我登陆生产环境（晚上）测试，完全没问题。问题应该是白天资源忙加上网络速度慢导致无法将生成的文件导出。

刚开始界面报如下错误：

上面是修改的代码，造成这个错误的原因是出现此错误 是因为，执行的数据库查询没有查询到任何结果，却调用了rs.next() 或者，游标到了查询出来的最后一条记录，又调用了rs.next()则，会找不到next条记录
ResultSet set1=statement.executeQuery(sql1);
ResultSet set2=statement.executeQuery(sql2);
