Error while inserting into blob column through PL/SQL

Question

Hi All,
I am trying to insert into column having blob as datatype.
INSERT INTO imagedb(image_name, content,description) VALUES ('logo.png',
?{file 'c:\logo.png'}, 'logo');
it gives me error Unknown JDBC escape sequence:
Is there anything wrong in above insert syntax for inserting into BLOB data type.
Can any body please help me.

It is not valid SQL as far as Oracle SQL is concerned. I assume that the file construct is suppose to replace that with the contents of the file?
What happens when the file size exceeds the max length of the SQL command?
And do you have any idea what will happen to the SQL Shared Pool on Oracle that needs to store the entire SQL command for every single SQL command passed to it? The whole purpose of the Shared Pool is for storing shared SQL. Not non-sharable SQL containing hardcoded values.
Bind variable are to be used.. if you expect Oracle to perform like only Oracle can.
And my bet is that you have not even bothered to read [url http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14249/toc.htm]Oracle® Database Application Developer's Guide - Large Objects guide....
