Hi, I’m getting an error when using lookup on a local cluster, does anyone know how to solve it?

whats the query

select who, lookup(‘mango_company’, ‘name’, ‘company_id’, company_id) from fetrace_biz limit 10

whats the name of the table that contains the company_id column

Lookup

function work with dimTable. But we found table could not be created successful with

isDimTable

= true.

@balci can you help here 🙂

got it, the DimTable need to have a primary key as @Lvszn Peng said, thanks everyone
