How to batch update data in Oracle using MyBatis?

To perform batch data updates in MyBatis using Oracle, you can follow these steps:

1. Create a Mapper interface with a method defined to update data in bulk:

public interface UserMapper {

    void batchUpdate(List<User> userList);
}

1. Write SQL statements in the corresponding Mapper XML file to achieve bulk updating operations.

<update id="batchUpdate" parameterType="java.util.List">
    <foreach collection="list" item="item" index="index" separator=";">
        UPDATE user SET name = #{item.name}, age = #{item.age} WHERE id = #{item.id}
    </foreach>
</update>

1. Call the methods from the Mapper interface in the code and pass in the list of data that needs to be updated.

List<User> userList = new ArrayList<>();
// 添加需要更新的数据到userList中

UserMapper userMapper = sqlSession.getMapper(UserMapper.class);
userMapper.batchUpdate(userList);
sqlSession.commit();

By following the above steps, you can achieve the operation of performing batch updates on data in Oracle using MyBatis.
