今天重新导库查询业务单据发现查询不到任何数据，查看日志发现是数据库报错了，数据库版本为Oracle11.2.0.1.0，报错为: 内部错误代码, 参数: [19004], [], [], [], [], [], [], [], [], [], [], []，网上查了一下是Oracle的BUG，解决方案如下

ORA-00600: 内部错误代码, 参数: [19004], [], [], [], [], [], [], [], [], [], [], []_数据库

连接数据库服务器，使用DBA用户登录，执行execute dbms_stats.delete_schema_stats('数据库用户名');

$ sqlplus / as sysdba
