-## Parse URLs
-
-One approach is to do regexes, something like:
-
-    SELECT substring(column_name FROM '[^/]+://([^/]+)/') AS domain_name FROM table_name;
-
-Eg:
-
-    SELECT DISTINCT(domain), COUNT(domain)
-        FROM (select substring(base_url FROM '[^/]+://([^/]*)') as domain FROM ingest_file_result) t1
-        WHERE t1.domain != ''
-        GROUP BY domain
-        ORDER BY COUNT DESC 
-        LIMIT 10;
-
-Or:
-
-    SELECT domain, status, COUNT((domain, status))
-        FROM (SELECT status, substring(terminal_url FROM '[^/]+://([^/]*)') AS domain FROM ingest_file_result) t1
-        WHERE t1.domain != ''
-            AND t1.status != 'success'
-        GROUP BY domain, status
-        ORDER BY COUNT DESC
-        LIMIT 10;
-
-Can also do some quick lookups for a specific domain and protocol like:
-
-    SELECT *
-        FROM ingest_file_result
-        WHERE terminal_url LIKE 'https://insights.ovid.com/%'
-        LIMIT 10;
