逻辑删除、物理删除

删除：逻辑删除、物理删除、批量删除。

一、逻辑删除

 public boolean delete(long id ){
    boolean isUpdate=buyer_receive_address.dao.update("update buyer_receive_address set deleted_at =? 
    where id = ?",new Date(),id);
    return isUpdate;
}

二、物理删除

物理删除可以直接使用sql语句的delete语句就解决了。

三、批量删除

批量删除同样类比物理删除，使用update语句。例如：

//ids id拼接的字符串

public boolean delete(String ids) {
boolean flag = update("UPDATE producer SET deleted_at = ? WHERE id IN (" + ids + ")", new Date());
return flag;
}

四、综合使用

public boolean deleteSalesman(String salesman_id_list) {
boolean flag = user_info.dao.update("UPDATE user_info SET deleted_at = ? WHERE id IN (" + salesman_id_list + ")", new Date());
if (flag) {
sec_user_permission.dao.deleteBy("user_id IN (" + salesman_id_list + ")");
}
return flag;
}
