Hi, The SQL solution for [1517. Find Users With Valid E-Mails](https://github.com/doocs/leetcode/blob/main/solution/1500-1599/1517.Find%20Users%20With%20Valid%20E-Mails/README_EN.md) is incorrect. **Problem**: The current query does not enforce case sensitivity for the domain `"leetcode.com"`. **Correct SQL**: ```sql SELECT * FROM Users WHERE mail REGEXP '^[a-zA-Z][a-zA-Z0-9_.-]*@leetcode\\.com$' AND BINARY mail LIKE '%@leetcode.com';
