How do you use {m,n} quantifiers in MySQL REGEXP to match a specific number of occurrences?

Q: How do you use {m,n} quantifiers in MySQL REGEXP to match a specific number of occurrences?

In MySQL regular expressions, the `{m,n}` quantifier allows you to match the **preceding element** a specific number of times: at least `m` times and at most `n` times. **Minimum and Maximum Occurrences:** `{m,n}` matches the preceding character or group at least `m` times and at most `n` times. **Exact Occurrences:** `{n}` matches exactly `n` occurrences; `{n,}` matches `n` or more occurrences. **Flexible Pattern Matching:** Can be combined with character classes, e.g., `[0-9]{2,4}` matches 2 to 4 digits. **Use with Groups:** You can apply `{m,n}` to grouped patterns, e.g., `(ab){2,3}` matches 'abab' or 'ababab'. This quantifier is useful when you need precise control over the number of repetitions of a character or sub-pattern in a string. SELECT code FROM products WHERE code REGEXP '^[0-9]{2,4}$'; -- Matches '12', '123', '1234' SELECT word FROM dictionary WHERE word REGEXP '^(ab){2,3}$'; -- Matches 'abab' or 'ababab' SELECT name FROM employees WHERE name REGEXP '^[A-Za-z]{3,}$'; -- Matches names with 3 or more letters
