The question is related to metabase I'm creating a new sql question I add a filter to it enter image description here
SELECT *
FROM testtable (nolock)
[[WHERE category = {{category}}]]
Next, I add this request to the dashboard and want to apply a multiple choice filter to it enter image description here
But I get the following error: "This field only accepts a single value because it's used in a SQL query." enter image description here
I tried changing the filter type for the request, but it didn't work
I need a multiple filter per request
