在 Java 中使用SimpleDateFormat将您的 String 解析为java.util.Date. 然后使用 aPreparedStatement并在其上设置日期。

编辑： 您可以使用PreparedStatementAleksander Blomskøld 已经建议的方法，并在Using Oracle to_date function for date string with milliseconds的帮助下：

final sql = "INSERT into IFT_VEHICLE_STATUS (LATITUDE, LONGITUDE, UPDATED_AT) " +
            "VALUES (?, ?, to_timestamp(?, 'DD.MM.YYYY HH24:MI:SS:SSFF3'))";
final PreparedStatement pstmt = con.prepareStatement(sql);
pstmt.setInt(1, 81000000);
pstmt.setInt(2, 162000000);
pstmt.setDate(3, oracleDate);

pstmt.execute();

老： 你想把 a 转换java.util.Date成 ajava.sql.Timestamp吗？你可以这样做：

try {
    final Date javaUtilDate = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").parse("2012-01-20 11:46:06");
    System.out.println("javaUtilDate = " + javaUtilDate);
    final Timestamp oracleDate = new Timestamp(javaUtilDate.getTime());
    System.out.println("oracleDate = " + oracleDate);
} catch (ParseException e) {
    e.printStackTrace();
}

这将给出以下输出：

javaUtilDate = Fri Jan 20 11:46:06 CET 2012
oracleDate = 2012-01-20 11:46:06.0
