【问题描述】：

对于我最近的工作，我使用的是 Microsoft Access 2007 数据库。在一个表中有两个字段文本和日期/时间。当我通过外部 java 代码访问表时，我在执行时收到错误消息。 特别是在与 Date Between 相关的 Execute Query 上。

以下是我的代码：-

                           System.out.println("Test Error "+e.getMessage());
                           e.printStackTrace();
                           


                             finally
                                     try

                                     catch (SQLException se) 
                                            se.printStackTrace();

    catch(Exception ex)
                            

  
   

结果和执行时的错误消息：-

请帮我在日期范围内生成报告。

【参考方案1】：

日期/时间值在 SQL 语句中使用 # 分隔符而不是 '。
