ORA-00600: 内部错误代码

错误实例：

生产环境，JAVA程序某功能报错：

ORA-00600: 内部错误代码, 参数: [qctcte1], [0], [], [], [], [], [], []

问题排查：

 org.hibernate.exception.GenericJDBCException: ORA-00600: 内部错误代码, 参数: [qctcte1], [0], [], [], [], [], [], [], [], [], [], []

问题SQL语句：

select count(*)
from (select a.ID_ as id, a.SOCIAL_ORGANIZATION_NAME as name, '社会组织' as type, a.CREATE_TIME, a.X as x, a.Y as y
      from SOCIAL_ORGANIZATION a
      where a.DEL_FLAG = 0
      union all
      select a.ID_ as id, a.LEGAL_REPRESENTATIVE_NAME as name, '非公有制经济组织' as type, a.CREATE_TIME, a.X as x, a.Y as y
      from NPSOE_ORGANIZATION a
      where a.DEL_FLAG = 0
      ORDER BY CREATE_TIME DESC) G

执行结果：

分析SQL，查找报错原因：

根据官方对于ORA-00600 [qctcte1]的解释，出错原因有可能是ORDER BY 语句，

修改ORDER BY 中的排序列，将排序列放在最后一个字段，执行通过。

修改后SQL语句：

select count(*)
from (select a.ID_ as id, a.SOCIAL_ORGANIZATION_NAME as name, '社会组织' as type, a.X as x, a.Y as y, a.CREATE_TIME
      from SOCIAL_ORGANIZATION a
      where a.DEL_FLAG = 0
      union all
      select a.ID_ as id, a.LEGAL_REPRESENTATIVE_NAME as name, '非公有制经济组织' as type, a.X as x, a.Y as y, a.CREATE_TIME
      from NPSOE_ORGANIZATION a
      where a.DEL_FLAG = 0
      ORDER BY CREATE_TIME DESC) G

执行结果：
