Hi All,
I am Akbar,
using the same script in my application
it is working fine in all cases.
orderby is not working
i am using following sample code

Untitled Document

function getSampleData()
{
var data = K.create.database({fieldName: ['id', 'name', 'age'],autoIncrement: ['id', {start: 1, step: 1}]});

data.Insert(['ghik', 46]);
data.Insert(['abcd', 15]);
data.Insert(['bced', 28]);
data.Insert(['cdef', 12]);
data.Insert(['defg', 9]);
data.Insert(['efgh', 38]);
data.Insert(['fghi', 35]);
data.Insert({name: ‘hikl’, age: 19});
data.Insert({name: ‘iklm’, age: 32});
data.Insert({name: ‘klmn’, age: 27});
data.Insert({name: ‘lmno’, age: 22});

var result = data.Select({id:”id”,name:”name”,orderby:”name”,limit:[0,11]});

var resultData = new TAFFY(result);

var tabbody = document.createElement(“tbody”);

resultData.forEach(function(data){

//alert(data.name);

var tabrow = document.createElement(“tr”);

var tabcell1 = document.createElement(“td”);
var tabcell2 = document.createElement(“td”);
var tabcell3 = document.createElement(“td”);

tabcell1.appendChild(document.createTextNode(data.id));
tabcell2.appendChild(document.createTextNode(data.name));
tabcell2.appendChild(document.createTextNode(data.age));

tabrow.appendChild(tabcell1);
tabrow.appendChild(tabcell2);
tabrow.appendChild(tabcell3);

tabbody.appendChild(tabrow);

});

var tab = document.createElement(“table”);

tab.appendChild(tabbody);
document.getElementById(‘showTable’).appendChild(tab);
}

I have a similar solution for this issue. My library is called Kombai. It allows you to select, insert, update, delete, order a client collection of data( syntax look like MySQL ):
//create a new database
var mydata = K.create.database({
fieldName: ["name", "phone"],
primaryKey: “phone”
});
// insert in to database
mydata.Insert(["ohay", "0987654321"]);
mydata.Insert(["oh", "0987654322"]);
mydata.Insert(["ha", "0987654323"]);
mydata.Insert(["hy", "0987654324"]);

mydata.Insert({”phone” : “0987654324?, “name” : “hy”});
mydata.Insert({”phone” : “0987654325?, “name” : “yo”});

//update
mydata.Update({”phone” : “232093430?, where: “name like ‘o%’”});
mydata.Update({”name”: “none”, where: “phone ==’0987654325?”});

//select
mydata.Select({fieldName: “phone”, where: “name like ‘%o%’”, orderBy: “phone”, Limit: 3});

//delete
mydata.Delete({Where: “name == ‘ohay’”});

//drop database:
mydata.drop();

other you can use select in DOM :

//getElementsByClassName
var list = K.select({from: document, where: “className == ‘toolbox’”});
var list2 = K.selcet({from: K(’id’), where: “nodeName == ‘SPAN’”});

hÄ±m i traying thatâ€™d be pretty sweet, particularly for browsers that donâ€™t yet have sqlite built in.

@porf & musicfreak.

You both missed the point. This isn’t a library that allows you to write Javascript to connect to your server side database.

This is a database written in Javascript that runs in the browser. It’s a bit like cookies with an SQLeque interface.

Will it work on IE7?
infact I would like to ask that can any library like Dojo can cater a buggy IE7/8 ‘s Cookie bug issue and store things normally?

would be fun to get this into a dojo.data store. You could even persist w/ dojox.storage…that’d be pretty sweet, particularly for browsers that don’t yet have sqlite built in.

poft: Not if you implement some sort of security mechanism. I mean, if you just allow any SQL query to be run on your server at any time, then yes, it’s unsafe. But you have to implement some sort of authorization system just like you would in a normal application.

I wrote a similar library for JavaScript that follows the ActiveRecord pattern but never released it publicly because there isn’t a ton of use for a client-side database other than long life single page apps. I really like the interface that Ian put on this DB though, it fits in better with the normal JavaScript programming style than ActiveRecord does. Suggestion: Make your documentation page wider than 400px because you’re wasting my screen space ;-).

Hmm, once i worked on something like this, but i stoped because its not safe

Anyone can go to firebug and execute some js that delete all your database etc

Maybe i am wrong but i don’t think so

I’ve seen a ton of these kind of systems, but I’ve never seen one on the client-side. To be honest, I’ve never even thought of the idea. This is great stuff. It’s probably not the first time such a simple idea has been implemented in JavaScript, but it’s the first time I’ve seen it, so to me it’s entirely new and amazing. I might actually use this in my web application (whenever that gets done).
