Question

Suppose I have two tables tblEmployee and tblEmpSalary. I need to write a SQL statement to get a list of all employees, their name and salary, who receive the highest salary in each department.

Sample table data is here:

Answer 1

SELECT e.strEmpName, s.monSalary
FROM tblEmployee e
JOIN tblEmpSalary s ON e.intEmployeeID = s.intEmployeeID
WHERE e.strDepartment + '-' + CAST(s.monSalary AS varchar(20)) IN (
     SELECT e2.strDepartment + '-' + CAST(MAX(s2.monSalary) AS varchar(20))
     FROM tblEmployee e2
     JOIN tblEmpSalary s2 ON e2.intEmployeeID = s2.intEmployeeID
     GROUP BY e2.strDepartment)

Disclaimer: I can’t test this query right now, so it could have some small detail wrong.
