Cause: The statement is ambiguous because it specifies two
or more tables having the same column name. For example, the
following statement is ambiguous because deptno is a column
in both tables: SELECT deptno, loc INTO my_deptno, my_loc
FROM emp, dept;
Action: Precede the column name with the table name (as in
emp.deptno) so that the column reference is unambiguous.
