How This Works

Audit a links or resources table in MySQL to identify records with invalid or malformed URL format using REGEXP. 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 validation — it avoids loading data into application memory just to filter it with a regex.
