How to query data divided into tables by time

Every month data a table,How do I query statistics within a year, It takes 12 tables,The tables that need to be queried change over time.Can the table to be queried be automatically matched according to the time,Or can add custom datasets through interfaces.

Hi @qishao, build a model in Metabase (you need to update the model every time a new table gets added), and then build questions based on that model
