Question

I have two tables set up. One for student information, one for student/class listing. I’m coding in PHP using the sqlsrv plugin for MSSQL 2008 R2.

Student ID
Class Code

Student ID
First Name
Last Name

I need to select all students from a class but order by last name.

SELECT student_id FROM table1 WHERE class_code LIKE '402843'
$students = SELECT last_name, first_name FROM table2 WHERE student_id LIKE 'all results of first query'

Right now I can select all the students and display all the information; however, I can not sort them by last name. I’m sure this is possible, but seeing that the first query will return an array, I need the second query to return an array as well.

Any help would be greatly appreciated.

Answer 1

Use IN subquery:

SELECT last_name, first_name FROM table2 WHERE student_id IN (SELECT student_id FROM table1 WHERE class_code='402843') ORDER BY last_name ASC
