plsql操作文件

--1.以dba登陆
conn / as sysdba;
--2.创建directory并分配权限
create or replace directory D_OUTPUT as 'G:/test'; 
grant read,write on directory D_OUTPUT to scott; 
grant execute on utl_file to scott;

--以scott用户连接数据库
conn scott/tiger;

declare
  v_file_handle utl_file.file_type;
  v_text varchar2(100):='Hello World!';    --存放文本
  v_filename varchar2(30) := 'log_'||to_char(sysdate,'yyyymmdd')||'.log'; 
begin
  v_file_handle:=utl_file.fopen('D_OUTPUT',v_filename,'a'); 
  utl_file.put_line(v_file_handle,v_text);
  utl_file.fflush(v_file_handle);
  utl_file.fclose(v_file_handle);
end;
