问题 I just wanted to know how I can store a picture in oracle data base ; 回答1: Well, as with anything in oracle, there are a handful of ways to store a photo. You can store it as a BLOB and should be pretty easy to implement loading photos into that type of field. A blob (in 10g) can store up to 8 terabytes in size. You could also use the READ_IMAGE_FILE and WRITE_IMAGE_FILE functions built into oracle forms and use a RAW datatype as opposed to a BLOB datatype. References: Asktom on READ_IMAGE
