Hi i am highly newbie about grafana,
My question about variables. Does Grafana support drilldown variables? I mean when i choose or select option/field on one variable. And other variable can change automatically/properly depend of data of course. Like a master detail relationship. e.g continent, country
And another question is the correct way to usage of variable like hard coded where clause for MS Sql server ?
How do you deal with the all value of option in the variable. lets assume we have a variable and it has distinct values and all option. like continents in the world. But my query stuck when i choose the all option.
My query hard coded query looks like
where column1 IN (@variable1)
when i select the all option my query looks like
where column1 IN (’’)
what is the correct solution of this problem.
