在mongo shell中找到mongoDB上2个文档之间的区别

P.S.您还可以像这样从shell加载一些第三方js库:load("D:\difference.js")希望获得帮助.I'm using mongodb 2.4.4 and I want to compare 2 documents, then print their differences only using the mongo shell. Is there a way to compare them? Something like:db.collection.compare({first_doc: objectID("blablalba"), sec_doc: objectID("blalba2")})and the output would be something like{diff1:{latitude:{first_doc:10.000, sec_doc:20.000}},diff2:{}}where latitude is the name of the field that had a difference.The output doesn't need to be exactly like that, but give the same functionality.Thanks 解决方案 Just declare native javascript function that can compare two objects in a way you need, then write a code like this:obj1 = db.test.findOne({"_id" : ObjectId("5176f80981f1e2878e840888")})obj2 = db.test.findOne({"_id" : ObjectId("5176f82081f1e2878e840889")})difference(obj1, obj2)Some native javascript difference functions can be found here or hereP.S. You can also load some third party js libs from shell like this:load("D:\difference.js")Hope this help. 这篇关于在mongo shell中找到mongoDB上2个文档之间的区别的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
