java.sql.SQLException : ORA-01403: no data found at struct. getDescriptor().getMetaData() 异常

Question

我使用 oracle.sql.STRUCT 类。通过以下代码:

ResultSetMetaData metaData = struct.getDescriptor().getMetaData();

我得到这个异常:

为什么会出现上述异常？什么是解决方案？

Answer 1

我找到了解决方案。问题是我的应用程序连接到数据库的用户没有授予目标类型。我向用户添加了授权，应用程序运行良好。
