The Regex Pattern

Regex pattern

^[a-zA-Z0-9._%+\-]+@[a-zA-Z0-9.\-]+\.[a-zA-Z]{2,}$

Use this pattern with SQLite's REGEXP operator.

SQLite SQL Example

-- Enable SQLite user-defined REGEXP function and use it to validate email format in a contacts table column
SELECT *
FROM your_table
WHERE your_column REGEXP '^[a-zA-Z0-9._%+\\-]+@[a-zA-Z0-9.\\-]+\\.[a-zA-Z]{2,}$';

How This Works

Enable SQLite user-defined REGEXP function and use it to validate email format in a contacts table column. The regex pattern is used with SQLite'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.
