使用准备好的语句迭代 sql resultSet 时出现 ArrayIndexOutOfBoundsException

Question

我在获取结果集时遇到以下错误。我正在使用 jdbc 瘦驱动程序 (ojdbc6)。有趣的是，它在处理 10 行 后给出了错误。我查看了一些论坛，发现 jdbc 驱动程序存在一些问题。我想知道我是否可以用这个驱动程序 (ojdbc6) 本身做点什么！！

在此方面提供任何帮助，我们将不胜感激。

这是 table 结构：

   );

Table 大约有 200 行，所有列的值最多为 4000 个字符。

查询格式：

select "COL1","COL2","COL3" ......."COL120" from SRC."TEST_SO_MANY_COLUMNS"

代码片段：

 Statement sel_stmt = connection.createStatement();
 ResultSet res = sel_stmt.executeQuery(query);
 res.setFetchSize(10000);
 ResultSetMetaData resultSetMetaData = resultSet.getMetaData();

获取结果集时未收到任何错误。迭代结果集时出现问题：

int count = 0;
if (resultSet.next()) {
    count++ ;
    //Do Something i.e. resultSet.getObject() .. and so on.. 
}
// Do something

上面的迭代对前 10 行工作正常，但之后出现以下异常。错误的堆栈跟踪：

java.lang.ArrayIndexOutOfBoundsException

Answer 1

这是一个很老的错误 (4751145)。它在 2005 年的 10.2 驱动程序中被报道。 10.2.0.3 驱动程序已修复。我的猜测是您运行要么是 10.2.0.1 要么是 10.2.0.2。

Oracle 下载页面在这里： http://www.oracle.com/technetwork/database/features/jdbc/index-091264.html

如果你想坚持使用 10.2 代码线，那么你应该移动到最新的补丁集 10.2.0.5。请注意，该驱动程序是向后兼容的，因此您还可以使用 11.2 甚至 12.1 驱动程序连接到 10g 数据库。
