Titanium数据库SQLite的使用

    

在Titanium的Database sqllit的使用如下：

// this sets the background color of the master UIView (when there are no windows/tab groups on it)
Titanium.UI.setBackgroundColor('#000');
//创建相关的数据库

//打开相关的数据库
var db = Titanium.Database.open('mydb');

// create tab group
var tabGroup = Titanium.UI.createTabGroup();
//删除表中的数据
//db.execute('DELETE FROM DATABASETEST');
//创建相关的表
db.execute('CREATE TABLE IF NOT EXISTS DATABASETEST (userName TEXT, passwd TEXT)');

//
// create controls tab and root window
//
var win2 = Titanium.UI.createWindow({  
    title:'添加人员',
    backgroundColor:'#fff'
});
var tab2 = Titanium.UI.createTab({  
    icon:'KS_nav_ui.png',
    title:'添加人员',
    window:win2
});


var lblName = Titanium.UI.createLabel({

    text:'用户名：  ',
    
    color:"#000000",

    top : Ti.Platform.displayCaps.platformHeight/2-200,

    left: 10,

    height:60,

    width:100,

    textAlign:'right'

});

var txtName = Ti.UI.createTextField({

    top:Ti.Platform.displayCaps.platformHeight/2-200,

    left: lblName.width,

    width:Ti.Platform.displayCaps.platformWidth-lblName.width-40,

    height:60

});



var lblPassword = Titanium.UI.createLabel({
    text:' 密码：  ',
    
    color:"#000000",
    
    top : Ti.Platform.displayCaps.platformHeight/2-110,

    left: 10,

    height:60,

    width:100,

    textAlign:'right'
});
var txtPassword = Ti.UI.createTextField({
	top : Ti.Platform.displayCaps.platformHeight/2-110,

    left : lblPassword.width,

    width : Ti.Platform.displayCaps.platformWidth-lblPassword.width-40,

    height : 60
});
var btnSubmit = Ti.UI.createButton({
	title : '添加',
	top: Ti.Platform.displayCaps.platformHeight/2-10,
	left:Ti.Platform.displayCaps.platformWidth/2-110,
	width : 100,
	height : 60
});




btnSubmit.addEventListener('click',function(e){
	var userName=txtName.value;
	var passwd=txtPassword.value;
	//入参的集合
	var personArray=[userName,passwd];
	//执行插入操作
    db.execute('INSERT INTO DATABASETEST (userName, passwd ) VALUES (?, ?)', personArray);
    //db.execute("COMMIT");
    //获取影响的行数
     Titanium.API.info('JUST INSERTED, rowsAffected = ' + db.rowsAffected);
     //获取影响行数的rowid
     Titanium.API.info('JUST INSERTED, lastInsertRowId = ' + db.lastInsertRowId);
     
    //创建一个提示框    
	var a = Titanium.UI.createAlertDialog({
		title:'添加人员信息',
		message:"人员添加成功",
		buttonNames: ['确定'],
	});
	a.show();
	
});



win2.add(lblName);
win2.add(txtName);



win2.add(lblPassword);
win2.add(txtPassword);

win2.add(btnSubmit);



//
