您可以使用以下java代码来获取新的插入id。

ps = con.prepareStatement(query, Statement.RETURN_GENERATED_KEYS);
ps.setInt(1, quizid);
ps.setInt(2, userid);
ps.executeUpdate();

ResultSet rs = ps.getGeneratedKeys();
if (rs.next()) {
    lastInsertId = rs.getInt(1);
}

我正在从一个基于jdbc的单线程应用程序中访问Microsoft SQL Server 2008 R2，并在不使用RETURN_GENERATED_KEYS属性或任何PreparedStatement的情况下拉回最后一个ID。看起来是这样的:

private int insertQueryReturnInt(String SQLQy) {
    ResultSet generatedKeys = null;
    int generatedKey = -1;

    try {
        Statement statement = conn.createStatement();
        statement.execute(SQLQy);
    } catch (Exception e) {
        errorDescription = "Failed to insert SQL query: " + SQLQy + "( " + e.toString() + ")";
        return -1;
    }

    try {
        generatedKey = Integer.parseInt(readOneValue("SELECT @@IDENTITY"));
    } catch (Exception e) {
        errorDescription = "Failed to get ID of just-inserted SQL query: " + SQLQy + "( " + e.toString() + ")";
        return -1;
    }

    return generatedKey;
} 

这篇博文很好地分离了三个主要的SQL Server“最后ID”选项: http://msjawahar.wordpress.com/2008/01/25/how-to-find-the-last-identity-value-inserted-in-the-sql-server/ -还不需要其他两个。

如果您正在使用Spring JDBC，您可以使用Spring的GeneratedKeyHolder类来获取插入的ID。

看看这个答案…… 如何使用Spring Jdbctemplate获取插入id。update(String sql, obj…args)

它也可以用于普通的语句(不仅仅是PreparedStatement)

Statement statement = conn.createStatement();
int updateCount = statement.executeUpdate("insert into x...)", Statement.RETURN_GENERATED_KEYS);
try (ResultSet generatedKeys = statement.getGeneratedKeys()) {
  if (generatedKeys.next()) {
    return generatedKeys.getLong(1);
  }
  else {
    throw new SQLException("Creating failed, no ID obtained.");
  }
}

当使用Statement时遇到“不支持的功能”错误。RETURN_GENERATED_KEYS，试试这个:

String[] returnId = { "BATCHID" };
String sql = "INSERT INTO BATCH (BATCHNAME) VALUES ('aaaaaaa')";
PreparedStatement statement = connection.prepareStatement(sql, returnId);
int affectedRows = statement.executeUpdate();

if (affectedRows == 0) {
    throw new SQLException("Creating user failed, no rows affected.");
}

try (ResultSet rs = statement.getGeneratedKeys()) {
    if (rs.next()) {
        System.out.println(rs.getInt(1));
    }
    rs.close();
}

其中BATCHID是自动生成的id。

Connection cn = DriverManager.getConnection("Host","user","pass");
Statement st = cn.createStatement("Ur Requet Sql");
int ret  = st.execute();
