Java HSQLDB-完整性约束冲突：唯一约束或索引冲突；块\u PK表：块

我是HSQLDB的新手，刚遇到这个错误，我在互联网上找不到任何解决方案，好像我遗漏了什么^^

我的应用程序目前除了创建两个表（如果它们还不存在的话）之外没有做任何其他事情

这是我处理HSQLDB的代码：

try {
    Class.forName("org.hsqldb.jdbc.JDBCDriver" );
} catch (Exception e) {
    System.err.println("ERROR: failed to load HSQLDB JDBC driver.");
    e.printStackTrace();
    return;
}

try {
    connection = DriverManager.getConnection("jdbc:hsqldb:file:"+mi.getDataFolder().getPath()+"\\data\\storage;hsqldb.lock_file=false", "SA", "");
    connection.prepareStatement(
            "CREATE TABLE IF NOT EXISTS Punishments (" +
            "id INTEGER IDENTITY PRIMARY KEY," +
            "name VARCHAR(16)," +
            "uuid VARCHAR(35)," +
            "reason VARCHAR(100)," +
            "operator VARCHAR(16)," +
            "punishmentType VARCHAR(16)," +
            "start BIGINT," +
            "end BIGINT," +
            "calculation VARCHAR(50))"
    ).execute();
    connection.prepareStatement(
            "CREATE TABLE IF NOT EXISTS PunishmentHistory (" +
            "id INTEGER IDENTITY PRIMARY KEY," +
            "name VARCHAR(16)," +
            "uuid VARCHAR(35)," +
            "reason VARCHAR(100)," +
            "operator VARCHAR(16)," +
            "punishmentType VARCHAR(16)," +
            "start BIGINT," +
            "end BIGINT," +
            "calculation VARCHAR(50))"
    ).execute();
} catch (SQLException e) {
    e.printStackTrace();
}

在我运行代码的前两次左右，它运行得很好，但在某些时候，我不断遇到以下错误：

我使用的是HSQLDB的2.4.0版，但也尝试了一些旧版本

<dependency>
    <groupId>org.hsqldb</groupId>
    <artifactId>hsqldb</artifactId>
    <version>2.4.0</version>
    <scope>compile</scope>
</dependency>

org.hsqldb
hsqldb
2.4.0
编译

感谢您提前提供的任何建议。

我最后不得不在关闭应用程序时调用“SHUTDOWN”SQL命令，并不时调用“CHECKPOINT”SQL命令

感谢您帮助我解决这个问题。

您可能正在使用旧版本的HSQLDB。试试最新版本。@fredt我使用的是HSQLDB的2.4.0，它应该是最新版本，还编辑了我的问题。无论如何，感谢您的帮助：）在其他语句之后添加connection.prepareStatement（“CHECKPOINT”）.execute（），它应该可以解决这个问题@fredt谢谢，这解决了我的一部分问题，但随后出现了一个稍微不同的异常。我对“CHECKPOINT”查询做了更多的研究，因为我从来没有听说过它，并且发现我应该在关闭应用程序时调用“SHUTDOWN”查询。这样就解决了所有的例外。非常感谢你的邀请help@Leoko嗨，我正在做JUnit测试，得到了相同的唯一性错误。能不能请你帮我查一下密码？以及需要粘贴代码的位置。
