如何对节点orm find中的项进行排序

Question

我想在node orm中使用find方法获取已排序的项目。我知道有和＆＃39;命令＆＃39;在find（）中的参数，它会给我排序的项目来自＆＃39; a-z＆＃39;。如果我想从＆＃39; z-a＆＃39;中获取商品，我该怎么办？这意味着＆＃39; GROUP BY DESC＆＃39;可以在node-orm中使用吗？

Answer 1

There is a method for group by

UserModel.find({id: id_value}).groupBy({column1, column2}).order('-name').

In the ORM library you can find the below function which will guide you more.

export interface SelectQuery {
select(fields: string): SelectQuery;
calculateFoundRows: SelectQuery;
as(alias: string): SelectQuery;
fun(fun: string, column: string, alias: string): SelectQuery;
from(table: string, from_id: string, to_id: string): SelectQuery;
from(table: string, from_id: string, to_table: string, to_id: string): SelectQuery;
where(...args: any[]): SelectQuery;
whereExists(table: string, table_link: string, link: string, conditions: { [column: string]: any }): SelectQuery;
groupBy(...columns: string[]): SelectQuery;
offset(offset: number): SelectQuery;
limit(limit: number): SelectQuery;
order(column: string, direction: string): SelectQuery;
build(): string;
}
