    Subquery within another subquery is called Nested Subquery. If the output of a subquery depends on column values of the parent query table then the query is called Correlated Subquery.

    SELECT adminid(SELEC Firstname+' '+Lastname  FROM Employee WHERE
     empid=emp. adminid)AS EmpAdminId FROM Employee;
    
    

    The result of the query is the details of an employee from the Employee table.
