Javascript 如何在ORDER BY和limit后动态添加查询参数

我正在做一个项目，需要动态地向查询添加参数。我的问题是：

 let query2 = "SELECT al.*,CONVERT_TZ(al.date_created,'+00:00',?) as date_created, user.first_name as agent_name  FROM `account_log` as `al`  inner join  `user` on user.id = al.user_id  WHERE `al`.`account_id` =  ?  ORDER BY `al`.`id` DESC  limit ?,?";
 let params2 = [tz_offset,account_id, offset, limit];

我想做以下几点：

query2 += " AND `event_type` = ? ";
params2.push(filter.event_type);

如何实现这一点？

查询参数必须在ORDER BY和LIMIT之前

首先添加动态参数，然后添加排序和限制

let query2 = "SELECT al.*,CONVERT_TZ(al.date_created,'+00:00',?) as date_created, user.first_name as agent_name  FROM `account_log` as `al`  inner join  `user` on user.id = al.user_id  WHERE `al`.`account_id` =  ?  ";
let orderAndLimit = "ORDER BY `al`.`id` DESC  limit ?,?";
let params2 = [tz_offset,account_id];
let orderAndLimitParams = [offset, limit]

query2 += " AND `event_type` = ? ";
params2.push(filter.event_type);

query2 += orderAndLimit;
params2.push(orderAndLimitParams);

我知道，但怎么知道？我在注释中的代码格式有问题，所以改变了我原来的回答实际上，你应该把它放在@atokle的答案中。如果我没弄错的话，除了“``”、粗体和斜体之外，注释中没有其他格式
