Det er meget nemmere:
PreparedStatement pstmt =
conn.prepareStatement("update blob_table set blob = ? where id = ?");
File blob = new File("/path/to/picture.png");
FileInputStream in = new FileInputStream(blob);
// the cast to int is necessary because with JDBC 4 there is
// also a version of this method with a (int, long)
// but that is not implemented by Oracle
pstmt.setBinaryStream(1, in, (int)blob.length());
pstmt.setInt(2, 42); // set the PK value
pstmt.executeUpdate();
conn.commit();
pstmt.close();
Det fungerer på samme måde, når du bruger en INSERT-sætning. Intet behov for empty_blob()
og en anden opdateringserklæring.
