WHERE your_column REGEXP '^(0[1-9]|1[0-2])/(0[1-9]|[12][0-9]|3[01])/\\d{4}$';How This Works
Validate US-style date strings in a MySQL column before type casting or migration. 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 validation — it avoids loading data into application memory just to filter it with a regex.
