SELECT *
FROM your_table
WHERE your_column REGEXP '^https?://([^/]+)';

How This Works

Extract the base domain from full URLs stored in a MySQL table using REGEXP_SUBSTR for domain-level analytics. The regex pattern is used with MySQL's REGEXP operator to filter rows at the database level.

Using regex directly in SQL is efficient for use cases like data extraction — it avoids loading data into application memory just to filter it with a regex.
