Question

I am a student this is my LAST homework assignment : )

/*
**(4.9) Calculate the minimum salary for exempt employees
**and the maximum salary for non-exempt employees.
*/

I can only use one select statement… or without running two separate queries

I have 2 tables…
Job_title

(Job_title varchar (50) PRIMARY KEY,
EEO_1_Classification varchar(200),
Job_description varchar(250),
Exempt_Non_Exempt_Status bit );

and

Employee

(Emp_id int NOT NULL IDENTITY(1,1)PRIMARY KEY, 
Last_name varchar(25), 
First_name varchar(25),
Address varchar(40),    
City varchar (15),
State char(2),
Telephone_area_code varchar(3), 
Telephone_number varchar(8),    
Job_title varchar(50) foreign key references job_title(job_title),  
Hire_date smalldatetime,    
Wage money,
Gender char(1),
Race varchar(25),
Age int );

They are linked by the job_title primary key/foreign key.

Any advice???

Answer 1

Calculate the minimum salary for exempt employees and the maximum salary for non-exempt employees:

select  min(case when j.Exempt_Non_Exempt_Status = 1 then e.Wage end)
,       max(case when j.Exempt_Non_Exempt_Status = 0 then e.Wage end)
from    Employee e
join    Job_title j
on      j.Job_title = e.Job_title
