文档解释

ORA-30569: data type of given column is not supported in a log group

Cause: An attempt was made to include a column with one of these unsupported data types: LONG, VARRAY, nested table, object, LOB, FILE, or REF in a log group.

Action: Change the column data type or remove the log group. Then retry the operation.

ORA-30569: data type of given column is not supported in a log group 的官方解释是：

ORA-30569: 日志组中不支持给定列的数据类型。

一般处理方法及步骤

1.使用DESCRIBE命令检查指定列的数据类型：

DESCRIBE [table] [column];

2.如果指定的列的数据类型无效，请将其转换为有效类型：

ALTER TABLE [table] MODIFY [column] [new_data_type];

3.最后，如果更改了表中某列的数据类型，请确保在将其添加到LogGroup之前重新编译表：

ALTER TABLE [table] COMPILE;
