1. 复制一条记录写入源数据表

示例：
insert into tasks select * from tasks where task_id='f5ef77262f1c467ea9483e29a529bf58';

2. 复制一条记录,然后修改字段值后写入源数据表

2.1 将field1 字段修改为 xiaoming

insert into table_name select 'xiaoming',field2,field3... from A where xx=xx;

示例：
insert into tasks select '123456',job_id,job_type,status from tasks where task_id='f5ef77262f1c467ea9483e29a529bf58';

2.2 将field1 字段修添加后缀

insert into table_name select concat(field1,'-suffix'),field2,field3... from A where xx=xx;

示例：
insert into tasks select concat(task_id,'-preffix'),job_id,job_type,status from tasks where task_id='f5ef77262f1c467ea9483e29a529bf58';
