BFILE的用法
(1)、create or replace directory
BFILE_TEST
as
'/oracle/oradata/bfiles';
(2)、grant read on directory BFILE_TEST to SCOTT;
(3)、host ls -l /oracle/oradata/bfiles/1.TXT
(4)、connect SCOTT/TIGER
create table BFILES (ID number, TEXT bfile );
(5)、insert into BFILES values ( 1,
bfilename ( 'BFILE_TEST', '1.TXT' ) );
create directory ww as 'd:\ww' --- 建立对应ORACLE文件夹
create table filelist(id varchar2(2), bf bfile,bb blob);---建表
insert into filelist values ('1',bfilename('ww','ss.txt'),'')---存入文件指针
问一下,这里的文件名需要带后缀名吗?(SS OR SS.TXT)
declare
b blob;
fb bfile:=bfilename('ww','ss.txt');
begin
select bb into b from sy where id='1' for update;
if(dbms_lob.fileexists(fb)!=0)
then
dbms_lob.open(b,dbms_lob.lob_readwrite);
dbms_lob.open(fb,dbms_lob.lob_readonly);
dbms_lob.loadfromfile(b,fb,dbms_lob.getlength(fb));
dbms_lob.close(fb);
dbms_lob.close(b);
commit;
end if;
EXCEPTION
when others then
dbms_output.put_line('falid');
end;
