Date Parameter in Derived Table used in more than one way

Looker Q&A Looker

Has anyone been able to efficiently parameterize a derived table with a date parameter such that the date is used in two different ways?

For example, given the SQL:

select
  sum(revenue)
from orders
left outer join invoices on orders.id = invoices.order_id
where
  order_date = '2023-01-01'
  and invoice_date >= '2023-01-01'

I know how to parameterize it with a templated filter

{% condition date_filter %} sales.order_date {% endcondition %}
and {% condition date_filter %} sales.invoice_date {% endcondition %}

so that both date criteria would equal the date passed in, but is there a way to get the SQL to use the date passed in for the >= clause on the other date field above?

I am able to do it by instead parameterizing a date_dim table, joining to that, and using the date returned in the two criteria, but then BigQuery isn’t able to take advantage of partitioning.

Any help would be appreciated!

Hi, If you can access into LookML.

Let try another way that you create a derived table in another view file.

Here is the document that you can refer

where
  order_date = {% date_start date_filter %}
  and invoice_date >= {% date_start date_filter %}

Didn’t know about date_start and date_end. Thank you!
