一、创建SQL Server数据库
建库：test
建表：
/*
Navicat MySQL Data Transfer Source Server : localhost
Source Server Version : 50520
Source Host : localhost:3306
Source Database : mo
Target Server Type : MYSQL
Target Server Version : 50520
File Encoding : 65001
Date: 2013-10-17 12:00:56
*/
-- ----------------------------
-- Table structure for [user]
-- ----------------------------
USE test
GO
DROP TABLE [user];
CREATE TABLE [user] (
id bigint NOT NULL PRIMARY KEY IDENTITY(1000, 1),
create_date datetime DEFAULT NULL,
edit_date datetime DEFAULT NULL,
is_delete int DEFAULT NULL,
[name] varchar(255) DEFAULT NULL,
sex varchar(255) DEFAULT NULL,
age int DEFAULT NULL
);
-- ----------------------------
-- Records of user
-- ----------------------------
INSERT INTO [user] VALUES ('2013-04-02 16:01:00', '2013-04-02 16:01:17', '0', 'Oppo', '男', '20');
INSERT INTO [user] VALUES ('2013-04-02 16:01:02', '2013-04-02 16:01:17', '0', 'Mini', '女', '18');
INSERT INTO [user] VALUES ('2013-04-02 16:01:04', '2013-04-02 16:01:17', '0', 'Kina', '女', '18');
INSERT INTO [user] VALUES ('2013-04-02 16:01:06', '2013-04-02 16:01:17', '0', 'Lora', '男', '19');
INSERT INTO [user] VALUES ('2013-04-02 16:01:08', '2013-04-02 16:01:17', '0', '榕Sir', '女', '18');
INSERT INTO [user] VALUES ('2013-04-02 16:01:10', '2013-04-02 16:01:17', '0', '兼容', '女', '19');
INSERT INTO [user] VALUES ('2013-04-02 16:01:13', '2013-04-02 16:01:17', '0', 'Sir云', '男', '18');
INSERT INTO [user] VALUES ('2013-04-02 16:01:17', '2013-04-02 16:01:17', '0', '明白了', '男', '18');
INSERT INTO [user] VALUES ('2013-04-02 16:37:00', '2013-04-02 16:37:00', '0', 'Guro Go Sir', '女', '19');
二、在页面JS代码操作数据库
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>JS操作数据库</title>
<script language="javascript" type="text/javascript">
var conn, rs; /*获取数据库连接*/
function getConnection() {
conn = new ActiveXObject("ADODB.Connection");
// 1.JavaScript操作数据库JS操作Access数据库
// 在F盘有文件abc.mdf，表名为user，一共2个字段，id数字类型主键，name文本类型
// conn.Open("DBQ=f://abc.mdb;DRIVER={Microsoft Access Driver (*.mdb)};");
// 2.JavaScript操作数据库JS操作SQL Server数据库
// 数据库名为：test，表名为user，id为int类型，自增列，name为用户名，为varchar类型；数据库用户名为sa，密码是sasa。
conn.Open("Driver={SQL Server};Server=.;DataBase=test;UID=sa;Password=sasa"); //打开数据库
return conn;
}
/*执行增删改的方法*/
function executeUpdate(sql) {
getConnection();
try {
conn.execute(sql);
return true;
} catch (e) {
document.write(e.description);
} finally {
closeAll();
}
return false;
}
/*执行查询的方法*/
function executeQuery(sql) {
getConnection();
try {
rs = new ActiveXObject("ADODB.Recordset");
rs.open(sql, conn);
var html = "";
while(!rs.EOF) {
html = html + rs.Fields("id") + " " + rs.Fields("name")+"<br/>";
rs.moveNext();
}
document.write(html);
} catch (e) {
document.write(e.description);
} finally {
closeAll();
}
}
/*关闭所有资源*/
function closeAll() {
if(rs != null) {
rs.close();
rs = null;
}
if(conn != null) {
conn.close();
conn = null;
}
}
// 增
// executeUpdate("INSERT INTO [user](create_date, edit_date, is_delete, [name], sex, age) VALUES ('2013-10-17 12:00:00', '2013-10-17 12:00:00', 0, '空', '男', 20)");
// 删
// executeUpdate("DELETE FROM [user] WHERE id = 1009");
// 改
// executeUpdate("UPDATE [user] SET sex = '女', age = 18 WHERE id = 1009");
// 查
executeQuery("select * from [user]");
