The Regex Pattern

Regex pattern

https?://[^\s<>]+

Use this pattern with PostgreSQL's ~ operator.

PostgreSQL SQL Example

-- Extract all HTTP/HTTPS URLs embedded in a text or description column using PostgreSQL regexp_matches function
SELECT *
FROM your_table
WHERE your_column ~ 'https?://[^\\s<>]+';

How This Works

Extract all HTTP/HTTPS URLs embedded in a text or description column using PostgreSQL regexp_matches function. The regex pattern is used with PostgreSQL's ~ 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.
