T-SQL (SS2K8) :: Select Query To Pull Required Data From 3 Tables

I have three tables EmpIDs,EmpRoles and LatestRoles. I need to write a select Query to get roles of all employees present in EmpIDs table by referring EmpRoles and LatestRoles.

Where I stuck : The condition is first look into table EmpRoles and if it has more than one entry for a particular Employee ID than only need to get the Role from LatestRoles other wise consider the role from EmpRoles .

Example:

Create Table #EmpIDs (
EmplID int
)
Create Table #EmpRoles (
EMPID int,

[Code] ....

Employee ID 2 is having two roles defined in EmpRoles so for EmpID 2 need to fetch Role from LatestRoles table and for remaining ID's need to fetch from EmpRoles .

My Final Output of select query should be like below.

EmpID Role
1 Role1
2 Role2
3 Role1
