Question

我是HSQLDB的新手，刚收到此错误，我无法在互联网上找到任何解决方案，似乎我错过了一些东西^^

我的应用程序目前没有做任何事情，除非创建两个表已经存在。

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();
}

我运行代码的前两次左右，它运行正常，但在某些时候，我不断收到此错误：

这是我收到错误后.log文件的示例：

INSERT INTO BLOCKS VALUES(0,2147483647,0)

/*C2*/SET SCHEMA PUBLIC

我使用的是HSQLDB版本2.4.0，但也尝试使用旧版本

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

提前感谢您的任何建议。

Answer 1

当我的应用程序被关闭时，我不得不最后调用“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。

HSQLDB - 完整性约束违规：唯一约束或索引违规; BLOCKS_PK表：BLOCKS
