The Regex Pattern
Regex pattern
^https?://(www\.)?[-a-zA-Z0-9@:%._+~#=]{1,256}\.[a-zA-Z0-9()]{1,6}([-a-zA-Z0-9()@:%_+.~#?&/=]*)$Use this pattern with MySQL's REGEXP operator.
MySQL SQL Example
-- Filter a links or products table in MySQL to find rows where url column contains valid HTTP or HTTPS URLs
SELECT *
FROM your_table
WHERE your_column REGEXP '^https?://(www\\.)?[-a-zA-Z0-9@:%._+~#=]{1,256}\\.[a-zA-Z0-9()]{1,6}([-a-zA-Z0-9()@:%_+.~#?&/=]*)$';How This Works
Filter a links or products table in MySQL to find rows where url column contains valid HTTP or HTTPS URLs. 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.
