sqlalchemy过滤多列 [英] sqlalchemy filter multiple columns

问题描述

如何合并两列并应用过滤器？例如，我要同时搜索名字和姓氏列。如果仅搜索一列，这就是我的操作方式：

How do I combine two columns and apply filter? For example, I want to search in both the "firstname" and "lastname" columns at the same time. Here is how I have been doing it if searching only one column:

query = meta.Session.query(User).filter(User.firstname.like(searchVar))

推荐答案

您可以简单地多次调用 filter ：

You can simply call filter multiple times:

query = meta.Session.query(User).filter(User.firstname.like(searchVar1)). \
                                 filter(User.lastname.like(searchVar2))
