How to "Enhance" Oracle ?
Hi,
I am a beginner user of Oracle 7.3 for Windows NT. I want to "enhance"
Oracle Server...
One of my tables contains a LONG RAW field to hold JPEG images. The
client end can submit a query with a image. The server end gets the input
image, compares it with the images in the table, and returns the result set
with a criterion of the similarity of the images (such as >=90%).
Obviously, the comparison cannot be implemented in SQL or PL/SQL. In fact,
it is written in C/C++. To reduce network traffic, I cannot do the
comparison at the client end, of course. So I MUST do the comparison at the
server end.
I won't modify the Client/Server architecture of Oracle DBMS. So, how can
I insert my C/C++ codes in to Oracle DBMS Server to do that? In fact, the
problem is, how can I write a function in C/C++, then I can use it like
other functions either stock in SQL or custom written in PL/SQL.
Thanks in advance.
