【问题描述】：

在我的数据库 created_date 数据类型列是 DATE 并且我想使用 ORACLE 数据库在 jdbc 中按 DATE 类型进行选择，但是当我运行此方法时像这样

Info infos = ExcellWriteToDatabase.readFromDataBase("2021-10-14 09:36:58");

，我收到此错误。如何解决这个问题呢？我尝试了很多东西，但都没有解决。

【解决方案1】：

这里的主要问题是您将 Java String 绑定到 Oracle 查询，而您应该绑定 JDBC 驱动程序可以在查询中转换为正确类型的日期/时间类型。考虑这个版本：

public static Info readFromDataBase(String createdDate) throws SQLException {
    // ...

    DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
    LocalDateTime dateTime = LocalDateTime.parse(createdDate, formatter);
    String sql = "SELECT PHONE_NUMBER, TEXT_MESSAGE FROM TEST WHERE CREATED_DATE = ?";
    PreparedStatement ps = connect.prepareStatement(sql);
    ps.setObject(1, dateTime);
    ResultSet resultSet = ps.executeQuery();
    if (resultSet.next()) {
        // process result set
    }

    // ...
}
