Hi team,
I tried to use lookup join a fact table with a dimension table, but I got
empty result for a Multi-valued column from the dimension table, is it a bug?
any workaround?
e.g.
SELECT
fact_id,
fact_col1,
LOOKUP('dimensiont_table', 'mutli_valued_column', 'fact_id', fact_id) AS
col2, -- nothing returned
LOOKUP('dimensiont_table', 'single_value_column', 'fact_id', fact_id) AS
col3 -- do have the value returned
FROM fact_table
thanks
