oracle中，拼接的字符串给游标赋值

直接open cur from sql;即可。

例子：

create or replace procedure test(tableName varchar2) is
 TYPE cur_type IS REF CURSOR;
 cur cur_type;
ajob varchar2(255 char);
curSql varchar2(255 char);
begin
  cursql :='select job from '||tableName;
  dbms_output.put_line('cursql'||cursql);
  open cur for cursql;
   loop
      fetch cur into ajob;
        exit when cur%notfound;
        update emp set job=job||'' where job=ajob;
     dbms_output.put_line('ajob'||ajob);

  end loop;
  close cur;

end;
