Question

我无法使用带弹簧框架的JdbcTemplate获取最后一个插入ID，在使用last_insert_id（）函数之前，我已经搜索了很多其他方法，但是没有使用它。顺便说一下，我的桌子有

private static final String insertResponse =
        "INSERT INTO response (" +
        " idReceiver) " +
        "VALUES (?)";

public static void saveResponse(Response response, User user) {
    dataSource = getDataSource();



    JdbcTemplate template = new JdbcTemplate(dataSource);

     //"select id from users where username ='"+ user.getUsername +"'";
    // define query arguments
    Object[] params = new Object[] { 1 };
    int[] responseTypes = new int[] { Types.INTEGER };
    int row = template.update(insertResponse, params, responseTypes);
    if (row >0){
    SqlRowSet rowSet = template.queryForRowSet("SELECT LAST_INSERT_ID() AS id");
    int lastInsertedID=0;
    if (rowSet.next())
        lastInsertedID = rowSet.findColumn("id");
    System.out.println("last insert row is : "+lastInsertedID);
}

我的响应表是由此命令创建的：

CREATE TABLE RESPONSE (
   ID INT NOT NULL PRIMARY KEY GENERATED ALWAYS AS IDENTITY 
   (START WITH 1, INCREMENT BY 1),
   idReceiver INT NOT NULL
 );

当我运行此代码时，我的JVM说＆＃34;嘿，你有这个例外： org.springframework.jdbc.BadSqlGrammarException：StatementCallback;错误的SQL语法[SELECT LAST_INSERT_ID（）AS id];嵌套异常是java.sql.SQLSyntaxErrorException：语法错误：遇到＆＃34;＆＃34;在第1行，第29栏。＆＃34;

如果有人遇到同样的问题，我已按照answer ..

解决了问题

    KeyHolder keyHolder = new GeneratedKeyHolder();
    template.update(
    new PreparedStatementCreator() {
        @Override
        public PreparedStatement createPreparedStatement(java.sql.Connection connection) throws SQLException {
             PreparedStatement ps =
            connection.prepareStatement(insertResponse, new String[] {"id"});
            ps.setInt(1, 1);
            return ps;
          }
        },
        keyHolder);

    System.out.println("last inserted id is "+keyHolder.getKey());

Derby - LAST_INSERT_ID（）不适用于JDBC
