【问题描述】*：

create table "task"(
    id int auto_increment primary key,
    name varchar(30) not null default '',
    success_num int not null  default 0,
    fail_num int not null  default 0
);

insert into task(name,success_num, fail_num)
values ('任务1', 2, 1), ('任务2', 4, 3);

在mysql中，批量操作，可以用如下语句

INSERT INTO task (id, name, success_num, fail_num)
VALUES (1, '任务1', 20, 10),
       (3, '任务3', 5, 4)
ON DUPLICATE KEY
UPDATE success_num =
VALUES (success_num), fail_num =
VALUES (fail_num);

达梦中，只能用MERGE INTO单条操作吗？

MERGE INTO task USING dual ON (id = 1)
    WHEN MATCHED THEN update set success_num = 20, fail_num = 10
    WHEN NOT MATCHED THEN insert (id, name, success_num, fail_num) values (1, '任务11', 20, 10);

MERGE INTO task USING dual ON (id = 3)
    WHEN MATCHED THEN update set success_num = 5, fail_num = 4
    WHEN NOT MATCHED THEN insert (id, name, success_num, fail_num) values (3, '任务3', 5, 4);
