used for custom data types. You are free to use any negative SUB_TYPE
(like SUB_TYPE -1) to indicate that that particular BLOB contains
JPEG data. Having subtypes for JPEG and for BMP one can create blob
filters to automatically perform translation between these types.
However, if you do not plan to use blob filters and do not need to
identify type of binary data by blob subtype (usually you know what
kind of content is stored in your column), you can use SUB_TYPE 0
(default one) to store generic binary data. Your table definition
will look like this:
CREATE TABLE PICTURES(
ID_PHOTO IDPHOTO,
NAME_PHOTO NAMEPHOTO,
FOTO BLOB SEGMENT SIZE 80)
I assume that you missed NAMEPHOTO domain in your previous post.
Hope this helps.
