"unsupported collating sort order" 从 Java 更新 Access 数据库时出错

Question

我想通过 NetBeans 使用 UCanAccess 对 Access table 做一个小改动，但我在第

行遇到了问题

pst.executeUpdate();

数据库详细信息：

database name : duruBistro.accdb
table name : person
field names: tc_no    (text)
             name     (text)
             surname  (text)
             salary   (number)

代码：

Connection conn = DriverManager.getConnection("jdbc:ucanaccess://C:\Users\ysnndr    \Documents\accessDB\duruBistro.accdb");
String query = "UPDATE PERSON SET SALARY = ? WHERE TC_NO = '189'";
PreparedStatement pst = conn.prepareStatement(query);
pst.setInt(1, 2500);         
pst.executeUpdate();

异常：

Answer 1

解释错误信息：

java.lang.IllegalArgumentException: Given index ... (PERSON) PrimaryKey ... is not usable for indexed lookups due to unsupported collating sort order

这是 Jackcess 的一个已知限制，Jackcess 是 UCanAccess 用来读写 Access 数据库文件的记录管理器。为了对主键类型为 Text 的表执行更新，Jackcess 要求 Access 数据库使用 "General" 或 "General - Legacy" 排序顺序。

更改相关 Access 数据库文件的排序顺序：

在 Access 中打开数据库。在 File > Options 下将 "New database sort order" 更改为 "General"（或 "General - Legacy"）。

对数据库执行"Compact and Repair Database"。（在 Access 2010+ 中，它位于功能区栏的 "Database Tools" 选项卡上。）
退出访问。

您的 Java 应用程序不应再抛出异常。但是，如果问题仍然存在，那么您的 Windows 语言环境也可能存在问题。请参阅了解另一种可能的解决方案。

Answer 2

3 分钟前我找到了解决方案，您必须更改主键类型（例如从 String 到 Integer），仅此而已。
