Flex tables and strange json parsing — Vertica Forum

Flex tables and strange json parsing

Hello!

 

I have the following column in a materialized view: 

 

 

public | flextable_view | my_column  | int   |    8 | (MapLookup(flextable.__raw__, 'field'))::int

 

But sometimes it is materialized as Null:

 

select (MapLookup(flextable_view.__raw__, 'field'))::!int, field from flextable_view where field is null;

MapLookup | field

Why is it happening?

 

Thank you,
