以获取正确的数据库路径

如何指定数据库文件是选择文件的示例 C：\work\mydatabase.db（在Windows中）

  Connection connection = DriverManager.getConnection（jdbc：sqlite：C：/work/mydatabase.db）; 
 

UNIX（Linux，Mac OS X等）file / home / leo / work /mydatabase.db

 连接connection = DriverManager.getConnection（jdbc：sqlite：/ home / leo / work /mydatabase.db）; 
 

如何使用内存数据库
SQLite支持内存数据库管理，它不创建任何数据库文件。要在Java代码中使用内存数据库，请按如下方式获取数据库连接：

 连接连接= DriverManager.getConnection（jdbc ：sqlite :: memory：）; 
 

这也可以帮助

  String path = this.getClass（）。getResource（apartments.db）。getPath（）; 
 connection = DriverManager.getConnection（jdbc：sqlite：+ path）; 
 

假设apartments.db放在项目根目录中

I am getting the following error:

java.sql.SQLException: [SQLITE_ERROR] SQL error or missing database (no such table: apartments)

In reality, the table does exist. The following is my code:

try {
    // load the sqlite-JDBC driver using the current class loader
    Class.forName("org.sqlite.JDBC");
    Connection connection = null;
    // create a database connection
    connection = DriverManager.getConnection("jdbc:sqlite:/Path/To/apartments.db");
    System.out.println(connection.getMetaData());
    Statement statement = connection.createStatement();
    statement.setQueryTimeout(30);

    ResultSet rs = statement.executeQuery("select * from apartments");
    while(rs.next()) {
        // read the result set
        System.out.println("TEXT = " + rs.getString("display_text"));
        System.out.println("X1 = " + rs.getInt("x1"));
    }
} catch (Exception ex) {
    Logger.getLogger(MouseEventDemo.class.getName()).log(Level.SEVERE, null, ex);
}

May be this can help you to get right path to you database

How to Specify Database Files

Here is an example to select a file C:\work\mydatabase.db (in Windows)

Connection connection = DriverManager.getConnection("jdbc:sqlite:C:/work/mydatabase.db");

A UNIX (Linux, Mac OS X, etc) file /home/leo/work/mydatabase.db

Connection connection = DriverManager.getConnection("jdbc:sqlite:/home/leo/work/mydatabase.db");

How to Use Memory Databases SQLite supports on-memory database management, which does not create any database files. To use a memory database in your Java code, get the database connection as follows:

Connection connection = DriverManager.getConnection("jdbc:sqlite::memory:");

This also can help

String path=this.getClass().getResource("apartments.db").getPath();
            connection = DriverManager.getConnection("jdbc:sqlite:"+path);

assumes that apartments.db is put in project root directory
