Aloha,



I am trying to create a PL/SQL procedure to recognize non-supported
filetypes that is stored as a BLOB in my database; more accurately it
is a ORDSys.ORDImage.



I want to do this by reading the first 1000 bytes of the file and then
do an INSTR after the occurence of a pattern, such as 'JFIF' or in my
case 'DICM' and 'MATRIX7'.



Does anyone have a best-practice for this kind of operation?



Kindly,


Erik Bengtsson
