PostgreSQL SQL Example
-- Use regexp_matches in PostgreSQL to extract phone numbers embedded in free-text columns like notes or addresses
SELECT *
FROM your_table
WHERE your_column ~ '\\+?[1-9]\\d{1,14}';How This Works
Use regexp_matches in PostgreSQL to extract phone numbers embedded in free-text columns like notes or addresses. 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.
