一：步驟##
1.sql server建立數據庫和相關表
2.建立數據源
(1).打開控制面板找到管理，打開ODBC選項或直接搜索數據源
(2).打開數據源配置后點擊添加，選擇sql server點擊完成
(3).給數據源命名，服務器選擇本機電腦sql server 服務器名下一步
后面全部點下一步或確定就可以了。
3.代碼設計
1.加載數據庫驅動
2.與數據源建立連接
3.與數據庫建立會話
4.操作數據庫
經常使用的一些JDBC URL###
JDBC-ODBC:jdbc:odbc:
####
Oracle:jdbc:oracle:thin:@
####
DB2:jdbc:db2:MyTest or jdbc.db2://localhost:6789/MyTest(需要用戶名和密碼)####
sql server數據庫連接###
package mybook;
import java.sql.*;
import javax.swing.JOptionPane;
public class bookdb {
String drivername="sun.jdbc.odbc.JdbcOdbcDriver";//驅動名
Connection conn;
Statement stmt;
ResultSet rs;
bookdb(){
try {
Class.forName(drivername);
conn=DriverManager.getConnection("jdbc:odbc:bookdb","sa","zhangyabiao");//與數據源bookdb建立連接
stmt=conn.createStatement();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public ResultSet find(String sql){//對數據庫進行數據查詢
try {
rs=stmt.executeQuery(sql);
return rs;
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return null;
}
}
public boolean update(String sql){//對增刪改
try {
stmt.executeUpdate(sql);
//JOptionPane.showInternalMessageDialog(null, "執行成功");
return true;
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
//JOptionPane.showInternalMessageDialog(null, "執行失敗");
return false;
}
}
}
