到底如何使用 python 将字符串变量传递到 GQL？我可以在 SQL 中很好地完成它，但它就是不工作。这是我所拥有的:
personalposts = db.GqlQuery("select * from PersonalPost where user_id = %s order by created desc limit 30" % user_id)
这让我很难受，但我觉得应该很简单。
谢谢!
最佳答案
这应该有效:
personalposts = db.GqlQuery("select * from PersonalPost where user_id =:1 order by created desc limit 30",user_id)
GqlQuery 语法示例:
q = GqlQuery("SELECT * FROM Song WHERE composer = 'Lennon, John'")
q = GqlQuery("SELECT __key__ FROM Song WHERE composer = :1", "Lennon, John")
q = GqlQuery("SELECT * FROM Song WHERE composer = :composer", composer="Lennon, John")
