Doing setBytes() but when extracting data get BLOB error?

Question

I am inserting a video into an oracle 10g db, and I insert it using the setBytes method but when trying to pull that video from the db, it gives me this error
SQL Exception in getting video ORA-00932: inconsistent datatypes: expected - got BLOB
The field value is a blob type, but don't have any issues when doing this with a jpg vs a wmv file. here is my code for insertion and extraction of the data.
                        String query=("INSERT INTO VIDEO (P_ID, P_VIDEONAME, P_VIDEO) Values (?,?,?)");
                        prepStmt = connection.prepareStatement(query);
                        prepStmt.setInt(1,patient.getP_ID());
                        prepStmt.setString(2,patient.getVideoName());
                        prepStmt.setBytes(3,patient.getVideo());
                        prepStmt.executeUpdate();
rs = stmnt.executeQuery("SELECT P_VIDEONAME, P_VIDEO FROM VIDEO WHERE P_VIDEO = " + patient.getVideoName() + " and P_ID = " + patient.getP_ID());
                        ResultSetMetaData metaData = rs.getMetaData();
                        int columns=metaData.getColumnCount();
                        while(rs.next()){
                            for(int i=1;i<=columns;++i) {
                                patient.setAction("getVideo");
                                patient.setVideoName(rs.getString(i));
                                patient.setVideo(rs.getBytes(++i));
                                sendPatient();
                    }catch(SQLException e) {
                        //this is similar to the definition i gave you above.
                        System.out.println("SQL Exception in getting video " + e.getMessage());

Answer 1

That inner for loop makes no sense. You don't need to iterate through the columns; you already know what's supposed to be in each one. Get rid of the loop and just refer to them by their absolute indices, like you did when you inserted the record.
Also, I would advise always using the postfix operators i++ and i-- instead of the prefix forms, ++1 and --i.  It's just too easy to lose track of what's going on when you mix the the two styles, and postfix operators are much more commonly used.
I don't know if any of this will solve your problem, but it should at least make the probelm easier to see.
