The Regex Pattern

Regex pattern

Use this pattern with MySQL's REGEXP operator.

MySQL SQL Example

-- Extract the 4-digit year from date strings in various formats stored in a MySQL transactions or events table
SELECT *
FROM your_table
WHERE your_column REGEXP '\\b(19|20)\\d{2}\\b';

How This Works

Extract the 4-digit year from date strings in various formats stored in a MySQL transactions or events table. 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 data extraction — it avoids loading data into application memory just to filter it with a regex.
