Google apps script 使用Google Apps脚本如何仅从ScriptDb检索具有属性/密钥的对象

是否可以查询ScriptDb以仅返回那些拥有特定属性/键的对象

results = db.query({key: db.not(null)}); // always triggers error "We're sorry, a server error occurred. Please wait a bit and try again."
results = db.query({key: db.not(undefined)}); // returns all objects in the database

反之亦然：

results = db.query({key: undefined}); 
results = db.query({key: null});         // both these cause an error on any of the ScriptDbResult methods "Your query object contains an invalid component."

有什么想法吗？

results=db.query{key:db.anyValue}；当然-错过了！ScriptDB已被弃用。相关的
