Validating Email Addresses and Phone Numbers Using REGEXP in MySQL

MySQL's REGEXP operator allows pattern-based validation of inputs such as email addresses and phone numbers.

Email Validation: Use REGEXP to check basic structure like username, @ symbol, domain, and TLD.

Phone Number Validation: REGEXP can validate digit counts, optional country codes, separators, and formats.
3
Flexibility: REGEXP enables enforcing input patterns without requiring external validation logic.
