| I have two tables. One called "Prof" and one called "Dept"The Prof table has the columns "pname" (Professor Name) and "dname" (Department Name)The Dept table has the columns "dname" (Department Name) and "numphds" (Number of PhD's)Of course this causes me Ambiguous column name 'dname'. which I understand because it shares the same named column "dname"How do I properly write the select statement to find names of professors who work in departments that have fewer than 50 PhD students.I know it is something to do with assignments, but I am confused. Thanks. |
