1、创建表，注意：插入图片的列要定义成BLOB类型
create table image_lob(t_id varchar2(5) not null,t_image blob not null);
2、创建图片目录，images为目录名
create or replace directory "images" as 'f:\pic\';
3、创建存储过程，filename为图片的名字，如‘cat.jpg’
create or replace procedure img_insert(tid varchar2,filename varchar2)as
f_lob bfile;
b_lob blob;
begin
insert into image_lob(t_id,t_image)
values(tid,empty_blob())return t_image into b_lob;
f_lob:=bfilename('images',filename);
dbms_lob.fileopen(f_lob,dbms_lob.file_readonly);
dbms_lob.loadfromfile(b_lob,f_lob,
dbms_lob.getlength(f_lob));
dbms_lob.fileclose(f_lob);
commit;
end;
/
4、执行上面的存储过程，实现图片的插入
exec img_insert('1','cat.jpg');
5、查看表
select * from image_lob;
