I'm trying to output a query where if any of the following columns contains NULL value (or for current sheet does not contain an empty string), then output the results, but it is still outputting results with null values. What am I doing incorrectly?
WHERE ((_http_requests.currentsheet IS NOT NULL OR _http_requests.currentsheet != '')
OR _http_requests.session_id IS NOT NULL
OR _http_requests.http_referer IS NOT NULL)
AND to make sure all columns in
where clause does not have any
SELECT * FROM PUBLIC._http_requests WHERE (_http_requests.currentsheet IS NOT NULL OR _http_requests.currentsheet != '') AND _http_requests.session_id IS NOT NULL AND _http_requests.http_referer IS NOT NULL
