連線資料庫實現查詢員工資訊

按步驟操作實現查詢

package com.zheng.z;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

public class JDBC2 {

	private Connection conn = null;
	private Statement stmt = null;
	private ResultSet result = null;

	public void queryEMP() {
		try {
			// 1、載入驅動
			Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");

			// 2、建立連線
			String url = "jdbc:sqlserver://localhost:1433;databaseName=test";
			String username = "zheng";
			String pwd = "123";
			conn = DriverManager.getConnection(url, username, pwd);

			// 3、建立sql語句
			stmt = conn.createStatement();
			String selectstr = "select * from info";
			result = stmt.executeQuery(selectstr);
			// 4、處理結果集
			System.out.println("員工編號：\t員工姓名：\t工作：");
			while (result.next()) {
				System.out.println(result.getString("id") + "\t" + result.getString("name") + "\t" + "\t"
						+ result.getString("job"));
			}
		} catch (Exception e) {
			e.getStackTrace();
		} finally {
			// 5、關閉資源
			try {
				if (result != null) {
					result.close();
					result = null;
				}
				if (stmt != null) {
					stmt.close();
					stmt = null;
				}
				if (conn != null) {
					conn.close();
					conn = null;
				}
			} catch (Exception e) {
				e.getStackTrace();
			}

		}

	}

	public static void main(String[] args) throws SQLException {
		// TODO 自動生成的方法存根
		JDBC2 c = new JDBC2();
		c.queryEMP();

	}
