关于java数据库Access
我在java在连接数据库2010,代码如下:
package stock;
import java.sql.*;
public class ConnectAccess {
public static void mbshow(ResultSet r)
{
try{
r.last();
System.out.println("数据库表共有"+r.getRow()+"条记录");
r.beforeFirst();
while(r.next())
{
System.out.println("第"+r.getRow()+"行记录");
System.out.println("\t股票代码:"+r.getString("股票代码"));
System.out.println("\t股票名称:"+r.getString("股票名称"));
System.out.println("\t股票价格:"+r.getString("股票价格"));
System.out.println("\t股票价格上限:"+r.getString("股票价格上限"));
System.out.println("\t股票价格下限:"+r.getString("股票价格下限"));
}
}catch(Exception e)
{
System.err.println("异常2:"+e.getMessage());
}
}
public static void main(String[]args)
{
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection c = DriverManager.getConnection("jdbc:odbc:Database","","");
Statement s = c.createStatement();
ResultSet r=s.executeQuery("select * from Stock");
mbshow(r);
}catch(Exception e)
{
e.printStackTrace();
}
}
}
结果出现错误,如下:
java.sql.SQLException: General error
