Missing table alias for derived table.

select min(grade) 
from 
(select grade from l_grade g 
join l_DesignationMaster d on g.DesignationId=d.DesignationId
join l_departmentmaster m on m.DepartmentId =d.DepartmentId
where d.departmentid=1 and g.grade not in (30)) t

or

select min(grade) as grade from l_grade g
join l_DesignationMaster d on g.DesignationId=d.DesignationId
join l_departmentmaster m on m.DepartmentId =d.DepartmentId
where d.departmentid=1 and g.grade not in (30)
