Include or exclude filter condition
When working with query filters, you can switch to finer-grained or coarser-grained representation of your data. With query_filters(){filter_condition}` or `+query_filters()-{filter_condition}, you can aggregate the results when including or excluding a filter condition.
Example
Filter condition: Ship Mode='car'
When you search on category Customer ID sales by customer id and category Ship Mode='car’, you can add a formula that calculate sales by category for each customer:
sales by Customer ID and Category = group_aggregate (
sum(Sales),
{Category, Customer ID },
query_filters()+{Ship Mode='air'}
)Alchemer Dashboard aggregates the results in the following manner:
Dimensions: ‘Category’ and ‘Customer ID’
Filters: ‘air’ and ‘car’.
Add a column to query filter
Add a query_filters()-{column} clause to an expression to aggregate the results while removing the expression related to the column.
Example
Filter condition: Ship Mode='car'
When you search on category Customer ID sales by customer id and category Ship Mode='car', you can add a formula that calculate sales for each customer, while ignoring the filter on the column:
sales by Customer ID and Category = group_aggregate (
sum(Sales),
{Customer ID, Category},
query_filters()-{Ship Mode}
)In this case, Alchemer Dashboard aggregates the results in the following manner:
- Dimensions: Customer ID
- Filters: none, because ignored
