**我使用此表将图像存储在sql数据库中：该表存储有关图像的ID，类别和描述。并且存储图像位置。我已经检索了类别和说明列...但我不知道如何从列图像中检索jpg图像**

        Index_img table

            Create Table index_img 
            ( 
               id int primary key,
               category  varchar(100) ,
               description  varchar(500) ,``
               image  blob
            ) ;

我想从我的表（index_img）中检索图像到我的jsp页面
