Oracle SQL : FROM keyword not found where expected

my query as follows.

WITH CTE AS
(
 SELECT EmpID, EmpName, EmpSalary,
 RN = ROW_NUMBER() OVER (ORDER BY EmpSalary DESC)
 FROM dbo.Salary
)
SELECT EmpID, EmpName, EmpSalary
FROM CTE
WHERE RN = @8thRow

I am getting error as

Error report -
SQL Error: ORA-00923: FROM keyword not found where expected
00923. 00000 - "FROM keyword not found where expected".

Can someone explain what is wrong with the code?

I think you are missing some of the code would you please include the initial part of the code as it is difficult to get as to what your query is

You can't assign a variable RN = ... like that in Oracle

Wrong syntax; an example based on Scott's schema:

SQL> select ename, sal from emp order by sal;

ENAME SAL
---------- ----------
SMITH 920
JAMES 950
ADAMS 1100
WARD 1250
MARTIN 1250
MILLER 1300
TURNER 1500 -- 8th --> you need this one
ALLEN 1600
CLARK 2450
BLAKE 2850
JONES 2975 -- ...
SCOTT 3000 -- 3rd
FORD 3000 -- 2nd
KING 10000 -- 1st, when sort is DESCending

14 rows selected.

SQL> with cte as
 2 (select empno, ename, sal,
 3 row_number() over (order by sal desc) rn
 4 from emp
 5 )
 6 select empno, ename, sal
 7 from cte
 8 where rn = 8;

 EMPNO ENAME SAL

Exactly you cant set Rn= you need to replace like the above because = in sql means to check for a condition not to assign a value there is := operator for assigning values to variable can try if it works.
