Inserting Clob with NamedParameterJdbcTemplate

Question

I usually use the lobHandler + JdbcTemplate + PreparedStatementSetter triplet to insert my Clob into the database, as I saw on http://www.java2s.com/Code/Java/Spring/InsertC

Answer 1

I'm using Spring 2.5.6 + Oracle and for me it worked straight away.

// Inserts file into DB and returns the key for the new row
public Number insert(String filename, byte[] data) {
    MapSqlParameterSource params = new MapSqlParameterSource();
    params.addValue("filename", filename);
    params.addValue("data", data);

    // Returns the autogenerated ID
    KeyHolder keyHolder = new GeneratedKeyHolder();
    String[] columnNames = {"ID"};

    // This is a NamedParameterJdbcTemplate
    jdbcTemplate.update(INSERT_SQL, params, keyHolder, columnNames);

    return keyHolder.getKey();
}
