推荐答案

下面是将图像插入表中的代码。

创建一个表来存储blob 。

Below is the code to insert an image into the table.
Create a table to store the blob.
CREATE TABLE tabblobs
( 	id varchar2(255),
	blob_col blob
);



在数据库中创建逻辑目录。


Create a logical directory in the database.

CREATE OR REPLACE directory MY_FILES AS 'd:\images';



使用逻辑

目录创建一个从物理磁盘加载blob的过程.gif ORATEST.gif必须存在于d:\ images.


Create a procedure to load the blob from the physical disk using the logical
directory. The gif "ORATEST.gif" must exist in d:\images.

CREATE OR REPLACE procedure insert_img AS
flob bfile;
blob blob;
BEGIN
	INSERT INTO tabblobs VALUES ( 'MyGif', empty_blob() )
	RETURN blob_col INTO blob;

	flob := bfilename( 'MY_FILES', 'ORATEST.gif' );
	dbms_lob.fileopen(flob, dbms_lob.file_readonly);
	dbms_lob.loadfromfile( blob, flob, dbms_lob.getlength(flob) );
	dbms_lob.fileclose(flob);
	COMMIT;
END;
