Hi @varnika
I don't know what you mean with "custom query". Metabase supports creating Native query in Mongo.
It sounds like you will need to make such query in Native instead of using the GUI.
Sorry, I meant "custom column" not "custom query".
Actually my goal t create a chart in which i can show "cumulative sum of (average of (total score))" but I have only "total score" column in my database. For postgres i can create another column easily but how can i do that in mongo? That's what i want to know.
i have created this question so that i can create cumulative sum of average of total score by using ask question "Ask question" tab again but i can't find this question in the saved question box.
May i know why, In postgres we can create a question from previous question, but here it is not possible.
