mybatis 批量复制同表数据并做修改字段，后插入。

一、复制同表数据，不做修改

INSERT INTO 表名 （字段）SELECT 字段 FROM 表名 WHERE 条件；

二、复制同表数据同时作出修改

<insert id="initializationTaskRules" parameterType="LgsOperationTaskRules">
        INSERT INTO lgs_operation_task_rules ( is_initialization, task_name, task_rules, date_interval, reminder_date, executive_role, task_describe, subtask, site_id ) SELECT
                                                                                                                                                                             is_initialization,
                                                                                                                                                                             task_name,
                                                                                                                                                                             task_rules,
