I have been trying to figure out how to get SQLite working on eclipse juno. I have been following the instructions on this site http://wiki.eclipse.org/Connecting_to_SQLite. The problem is not every step is exactly as explained so I am guessing on weather I got it right or not. I feel that I have probably gotten it all correct until step 13, there is no SQL Model-JDBC Connection entry. So I have tried step 13-16 with a generic JDBC and with one that says SQLite. The SQLite one does not have a driver which is no surprise due to step 5. Any way that I have tried so far ends up failing ping with details listed below. Someone must have a better way through this process.
我一直试图弄清楚如何让SQLite在eclipse juno上工作。我一直按照本网站上的说明http://wiki.eclipse.org/Connecting_to_SQLite。问题不在于每个步骤都与解释完全一致，因此我猜测天气是否正确。我觉得我可能已经完全正确，直到第13步，没有SQL Model-JDBC Connection条目。所以我尝试使用通用JDBC和使用SQLite的步骤13-16。 SQLite没有一个驱动程序，由于步骤5没有任何意外。我迄今为止尝试过的任何方式都会导致ping失败，下面列出了详细信息。有人必须有更好的方法来完成这个过程。

Make sure you get the driver from https://bitbucket.org/xerial/sqlite-jdbc/downloads, then import the driver into your project.
确保从https://bitbucket.org/xerial/sqlite-jdbc/downloads获取驱动程序，然后将驱动程序导入到项目中。
Now you can test the configuration by creating a java class Sample.java
现在，您可以通过创建java类Sample.java来测试配置
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
public class Sample
{
public static void main(String[] args) throws ClassNotFoundException
{
// load the sqlite-JDBC driver using the current class loader
Class.forName("org.sqlite.JDBC");
Connection connection = null;
try
{
// create a database connection
connection = DriverManager.getConnection("jdbc:sqlite:sample.db");
Statement statement = connection.createStatement();
statement.setQueryTimeout(30); // set timeout to 30 sec.
statement.executeUpdate("DROP TABLE IF EXISTS person");
statement.executeUpdate("CREATE TABLE person (id INTEGER, name STRING)");
int ids [] = {1,2,3,4,5};
String names [] = {"Peter","Pallar","William","Paul","James Bond"};
for(int i=0;i<ids.length;i++){
statement.executeUpdate("INSERT INTO person values(' "+ids[i]+"', '"+names[i]+"')");
}
//statement.executeUpdate("UPDATE person SET name='Peter' WHERE id='1'");
//statement.executeUpdate("DELETE FROM person WHERE id='1'");
ResultSet resultSet = statement.executeQuery("SELECT * from person");
while(resultSet.next())
{
// iterate & read the result set
System.out.println("name = " + resultSet.getString("name"));
System.out.println("id = " + resultSet.getInt("id"));
}
}
catch(SQLException e){ System.err.println(e.getMessage()); }
finally {
try {
if(connection != null)
connection.close();
}
catch(SQLException e) { // Use SQLException class instead.
System.err.println(e);
}
}
}
}
The code will create a database named sample.db, inserting data into, and then prints the rows.
代码将创建一个名为sample.db的数据库，将数据插入，然后打印行。
