SET    @CodeFrom = 500 
SET    @CodeTo= 503

UPDATE tHREmployee
SET    DepartmentID = (
                          SELECT DepartmentID 
                          FROM   tHRDepartment

那这个呢：

 Declare @NewDepID int
 Select   @NewDepID = DepartmentID from Departments Where DepartmentCode = 503

 update tHREmployee 
 Set DepartmentID = @NewDepID
 Where DepartmentID in (Select DepartmentID from Departments Where DepartmentCode = 500)
