If you're creating a dynamic filtered measure like in this article, "if a user does not select a value in the filter-only field, the SQL will default to 1=1 (having no filtering effect on the measures)."
If you want to be able to have a default value for when a user doesn't select a value on the filter, we can use something like this:
filter: status_filter {
type: string
suggest_dimension: status
}
dimension: status_satisfies_filter {
type: yesno
hidden: yes
sql: {% if status_filter._is_filtered %}
{% condition status_filter %} ${status} {% endcondition %}
{% else %}
${status} = "cancelled"
{% endif %};;
}
measure: count_dynamic_status {
type: count
filters: [status_satisfies_filter: "yes"]
}
What you put after the {% else %} will be the default value applied to the filtered measure.
