Write a query to retrieve the first four characters of the name
Description: Show the first four letters of every student name.
Tables: the exercises use the students (id, name, city, marks, course_id) and courses (id, course_name) tables, with the data from our MySQL INSERT chapter. The students are: Robin (Delhi, 85), Maria (Mumbai, 92), John (Pune, 78), Asha (Jaipur, 88), Vikram (Delhi, 65), Neha (Mumbai, 45).
Hint:
- Use
LEFT(name, 4)orSUBSTRING(name, 1, 4).
MySQL query for the first four characters
SELECT name, LEFT(name, 4) AS first_four
FROM students;
Output:
