WHERE your_column REGEXP '^[0-9]+$';

How This Works

Find rows in a MySQL table where a column that should contain mixed content has only numeric characters. 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 string matching — it avoids loading data into application memory just to filter it with a regex.
