SQLAlchemy IN 子句 [英] SQLAlchemy IN clause

问题描述

我正在尝试在 sqlalchemy 中执行此查询

I'm trying to do this query in sqlalchemy

SELECT id, name FROM user WHERE id IN (123, 456)

我想在执行时绑定列表[123, 456].

I would like to bind the list [123, 456] at execution time.

推荐答案

怎么样

session.query(MyUserClass).filter(MyUserClass.id.in_((123,456))).all()

编辑:如果没有 ORM，它将是

edit: Without the ORM, it would be

session.execute(
    select(
        [MyUserTable.c.id, MyUserTable.c.name], 
        MyUserTable.c.id.in_((123, 456))
    )
).fetchall()

select() 有两个参数，第一个是要检索的字段列表，第二个是 where 条件.您可以通过 c(或 columns)属性访问表对象上的所有字段.

select() takes two parameters, the first one is a list of fields to retrieve, the second one is the where condition. You can access all fields on a table object via the c (or columns) property.
