you can insert any kind of file to database by using following code
i hope this program will usefull for you
Example on storing images into BLOB data type.
- Managing SQL 92 data types (BLOB, CLOB and Ref)
BLOB (Binary Large OBject)
Used to store binary informations like images, audio files etc
-For each byte one byte of memory will be allocated
-Size can vary up to 4GB for each entry
CLOB (Character LOB)
-Used to store character information like plain, word documents
-For each character two bytes of memory is allocated
-Size up to 4GB
Ref (Reference):
-The column declared with this data type instead of storing a file into
DB contains
a pointer pointing to the file located in the hard disk
-Size up to 4GB

Hi there well i am having a problem in one of my current projects and
it is that
i have to insert an 4 dimention array into a database and the best
thing i was adviced until now is to use a BLOB, but BLOB is just an
interface in java.sql.* so how can i create an object of Blob and
again how i can insert my 4d array to it.
