Assign dashboard query result to variable


In Dashboard settings>Variables>Edit i can create a variable referencing a dashboard i already have.

what is the syntax of querying the dashboard?

ive read this (awaited to find syntax there)


and all other places in documentation about dashboards as data sources and queries.

thanks in advance

so… my admin updated grafana to latest 8.*
and the dashboard word from that dropdown list for variables completely disappeared.

still i can query grafana as datasource - question is how?
