A developer is defining the users table within a view file in Looker. Theusers 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?
A developer wants tocreate a measure that shows the item count broken out by category. When a second, more granular dimension is added to the same query, the count broken out by category should still represent the original aggregation and be duplicated on each line. The business wants this “count” in “category” available in the Explore section without any additional work done by the end user. For example:
The Count column represents the count for each combination of Category and Item.
The Count in Category column represents the count for each Category only.
How can the developer address this need with a LookML object?
A LookML developer finishes some LookML work and commits changes in their personal development branch. The developer is asked to Pull and Merge Other Changes.
What does this indicate?
A developer has the dimensions enrollment_month and graduation_month already defined in the view. Both were created as part of dimension_groups of type: time. The developer need touse these two dimensions in the sql_start and sql_end parameters of a dimension group of type: duration.

A)
B)
C)

A user reports the following SQL error when selecting the discounted sale price field:
ERROR: column “order_items.sale_price”; must appear in the GROUP BY clause or be used in an aggregate function.
The developer checks the field definition and finds it to be:
measure: discounted_sale_price {
type: number
sql: ${sale_price} * 0.8 ;;
}
The developer also finds the LookML definition of the sale_price field to be:
dimension: sale_price {
type: number
sql: ${TABLE}.sale_price ;;
}
What isthe likely cause of the SQL error?
