package com.test4;


import java.sql.*;

public static void main(String[] args) {

ps = ct.prepareStatement("select * from SC1");
rs = ps.executeQuery();
while(rs.next()){
System.out.println("测试");
}
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}finally{
try {
if(rs != null){

} catch (SQLException e) {

}

源代码出现下面的异常

其中数据库stucoursedase"如下：

经过测试：

    出现错误的可能原因：只能使用默认数据库master进行查询

需要解决的问题是：

  如何才能访问自己指定的数据库？？
