@Jackie-Jiang extracting a field is definitely a good approach for some use cases. Perhaps JSON is a bit of a red herring; what I really would like to see supported is columns allowing repeated records that have a fixed schema. Effectively, a column which itself is a table, or sometimes referred to as nested data types. One issue with the idea of extracting values to other columns is that context is lost. If I want to perform conjunctions on records where multiple fields within a single record must match query predicates (which JSON_MATCH supports), that can’t be done by extracting data from a single field to another column.
