A developer wants to create a new Explore based on the order_items view. The developer creates an Explore in the ecommerce model file with the following definition:
explore: order_items {}
After saving and validations, the developer receives this LookML validator error:
Inaccessible view “inventory_items”, “inventory_items” is not accessible in explore” “order_items”. Check for typos and missing joins in explore “order_items”.
What caused this error to appear?
A developer is defining the users table within a view file in Looker. The users table will be available as an individual Explore and it will also be joined into other Explores, such as the products Explore. The developer needs to limit the fields visible in the products Explore without affecting the visibility of the fields in the users Explore.
How should the developer meet this requirement?
Users must be able to click on the Country field in their Explore and be redirected to another Explore that shows all countries compared.
Which parameter should be added to the country dimension to create a connection to this other associated Explore?
A user reports an error message on an Explore: “Non-unique value/primary key (or sql_distinct_key), value overflow or collision when computing sum”.
What should the LookML developer check for in the joined views of the Explore?
