HSQLDB连接错误

Question

我创建了一个连接HSQLDB的java程序，第一个程序运行良好，

public final static String DRIVER = "org.hsqldb.jdbcDriver";
public final static String URL = "jdbc:hsqldb:file:F:/hsqlTest/data/db";
public final static String DBNAME = "SA";

但这些不是

public final static String DRIVER = "org.hsqldb.jdbcDriver";
public final static String URL = "jdbc:hsqldb:file:C:/Program Files/tich Tools/mos tech/app/data/db/t1/t2/01/db";
public final static String DBNAME = "SA";

错误显示如下：

我在googled上搜索了这个连接问题，但大多数问题都没有多大帮助，有人说这可能是HSQLDB版本的问题。dbase在“关闭压缩”模式下关闭。有人给我建议吗？

Answer 1

因为在第二个URL中在Relative Path.之间有空格

C:/Program Files/tich Tools/mos tech/app/data/db/t1/t2/01/db
          ^          ^         ^

使用单引号''。

相对数据库文件路径可以在 独立于平台的方式如：'dir1/dir2/.../dirn/file-name-prefix'.
