一.查找
public class class1 {
public static void main(String[] args) {
// TODO Auto-generated method stub
try {
//1.找到数据库，并且链接上
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
Connection conn = DriverManager.getConnection("jdbc:sqlserver://192.168.8.60;DataBaseName=School","sa","123456");
//3.创建数据库输出方式SQL语句
String sql= "select [sid],[stuName],[sex],[age] from [Student]";
//2.取出数据库中的数据以SQL的方式
Statement stmt= conn.createStatement();
//4.取出所有的数据库的数据
ResultSet rst = stmt.executeQuery(sql);
//5.将数据库中的数据一个个取出来
while(rst.next()){
int one=rst.getInt("sid");
String two= rst.getString(2);
String three = rst.getString(3);
int fore = rst.getInt(4);
System.out.println("学号为："+one+"，的名字是"+two+",性别是"+three+",年龄是："+fore);
}
//6.关闭数据
if(!rst.isClosed()){
rst.close();
} if(!stmt.isClosed()){
stmt.close(); }
if(!conn.isClosed()){
conn.close(); }
} catch (ClassNotFoundException e1) {
// TODO Auto-generated catch block e1.printStackTrace();
}catch (SQLException e) {
// TODO Auto-generated catch block e.printStackTrace(); }
}
