1.连接sql2005的实例

方法1:往数据库中插入数据,创建一个java项目.创建一个class.

建立一个数据库test,创建表名为UserInfo(UserID,password)

使用PrepareStatment

package com.v512.example;

import java.sql.*;
import java.lang.*;

public class JDBCExample {

	public static void main(String[] args) {

				String sql = "insert into UserInfo(UserID,password) values(?,?)";
		try {
			Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
			Connection con = DriverManager.getConnection(
					"jdbc:sqlserver://localhost:1433;DatabaseName=test", "sa",
					"123");
			PreparedStatement pStatement = con.prepareStatement(sql);
			pStatement.setString(1, "XXXXX");
			pStatement.setString(2, "101010");
			pStatement.executeUpdate();
			pStatement.close();
			con.close();

		} catch (Exception e) {
			// TODO: handle exception
		}
	}

}

??2.使用statement插入数据

package com.v512.example;

import java.sql.*;
import java.lang.*;

public class JDBCExample {

	public static void main(String[] args) {

		ResultSet rs = null;
		String sql = "insert into UserInfo(UserID,password) values('XXXXXXX','1010010101010')";
		try {
			Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
			Connection con = DriverManager.getConnection(
					"jdbc:sqlserver://localhost:1433;DatabaseName=test", "sa",
					"123");
									Statement statement=con.createStatement();
		    rs=statement.executeQuery(sql);
		    statement.close();
		    rs.close();

		} catch (Exception e) {
			// TODO: handle exception
		}
	}

}

3.查询数据库的结果!

package com.v512.example;

import java.sql.*;
import java.lang.*;

public class JDBCExample {

	public static void main(String[] args) {

		ResultSet rs = null;
				String sql="select * from UserInfo";
		try {
			Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
			Connection con = DriverManager.getConnection(
					"jdbc:sqlserver://localhost:1433;DatabaseName=test", "sa",
					"123");
						
			PreparedStatement statement=con.prepareStatement(sql);
			rs=statement.executeQuery();
			while (rs.next()) {
			System.out.println("name:"+rs.getString("UserID")+"\tpassword:"+rs.getString("password"));
			}
          statement.close();
          con.close();
		} catch (Exception e) {
					}
	}

}
