I tried to materialize some fields for a Flex table and got the following:
testdb=> select materialize_flextable_columns('stagging_2015_03_04',3);
ERROR 6035: Table "public.stagging_2015_03_04_keys" has no non-null records under the column key_name
HINT: Please ensure Table "public.stagging_2015_03_04" contains data and run compute_flextable_keys()
Basically, I just manually added some fields (key_name, frequency, data_type_guess)'s needed to be materialized into the table public.stagging_2015_03_04_keys, instead of populating the table with the Vertica
function compute_flextable_keys and got the above error. Is there any people knows how to fix this?
