In this video I will show you how to write dynamic sql queries for Postgres data source in Grafana.

The sql queries for variables:

markers:
SELECT column_name as __text, ' and ' || column_name || '::numeric = 1' as __value FROM information_schema.columns WHERE table_schema = 'public' AND table_name = 'sample_table'
and column_name != 'summary'

query
select 'where ' || substring(replace( '${markers:raw}', ',', ''), 5)
