mybatis 批量复制同表数据并做修改字段，后插入。

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, date_interval, reminder_date, executive_role, task_describe, subtask, #{siteId} AS site_id FROM lgs_operation_task_rules r WHERE r.is_initialization = 1 AND r.site_id IS NULL </insert>
