How This Works

Clean up a name or description column in MySQL by removing extra whitespace using REGEXP_REPLACE. 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.
