Variable formatted as regex & MySQL double-escaping of backslashes

[mattabrams]

Hi @carlosabalde

Not sure but maybe this solution will be of some use?

Template variable with single quote(') being represented as double quote ('') in qurey section

What do the settings look like for the $country_name variable? Is it a MySQL query or a “custom” variable? Multi or single value? You could try ${country_name:raw} so that Grafana does not try to do any interpolation or escaping.
