JDBC를 사용하여 데이터베이스에 이미지를 삽입하는 방법은 무엇입니까?

CREATE TABLE Tutorial(Name VARCHAR(255), Type INT NOT NULL, Logo BLOB);

String query = "INSERT INTO Tutorial(Name, Type, Logo) VALUES (?, ?, ?)";
PreparedStatement pstmt = con.prepareStatement(query);

FileInputStream fin = new FileInputStream("javafx_logo.jpg");
pstmt.setBinaryStream(3, fin);
