如果已知部门可以写静态sql：

declarecv_sql varchar2(5000):=' ';cn_number number;cn_i number :=0;sql_query varchar2(5000);begin for v_cur in (select distinct name into cn_number from department)loopcv_sql:= cv_sql||',sum(decode(name,'''|| v_cur.name ||''',quantity,0)) '|| v_cur.name;end loop;sql_query:='create or replace view query_zjx_v as select quarter'||cv_sql||' from department group by quarter';dbms_output.put_line(sql_query);execute immediate sql_query;end;
