Execute immediate v_SQL;
where v_FY0 is NUMBER(10);v_SQL NVarchar2(4000),v_InsertType VARCHAR2(4000); and v_OffSet Number(10); v_tblInsertType VARCHAR2(4000);
Upon executing, I get: v_FY0 =2018 and v_OffSet = 0;
Upon executing ,i am getting the error - ORA-00923: FROM Keyword not found where expected.
How to resolve this issue and how to get this working.

You can't use as in the from clause.
This query:
select * from (select dummy from dual) as tab
produces error ORA-00933. So simply remove as:
select * from (select dummy from dual) tab
