+Table: Users
+
++----------------+---------+
+| Column Name    | Type    |
++----------------+---------+
+| user_id        | int     |
+| name           | varchar |
++----------------+---------+
+user_id is the primary key (column with unique values) for this table.
+This table contains the ID and the name of the user. The name consists of only lowercase and uppercase characters.
+
+
+Write a solution to fix the names so that only the first character is uppercase and the rest are lowercase.
+
+Return the result table ordered by user_id.
+
+The result format is in the following example.
+
+
+
+Example 1:
+
+Input: 
+Users table:
++---------+-------+
+| user_id | name  |
++---------+-------+
+| 1       | aLice |
+| 2       | bOB   |
++---------+-------+
+Output: 
++---------+-------+
+| user_id | name  |
++---------+-------+
+| 1       | Alice |
+| 2       | Bob   |
++---------+-------+
+
+
+
+
+# Write your MySQL query statement below
+SELECT user_id, 
+       CONCAT(UPPER(LEFT(name, 1)), LOWER(SUBSTRING(name, 2))) AS name 
+FROM Users 
+ORDER BY user_id;
