Is it possible to add a package.json file for us who are sticking with NPM?

Hello!
how can i call 'not equal' != or 'Different' <> operators with angular-websql ?
i want to put a dynamic parameter into my query condition like that:

db.del("Table", {"id_element":{'value':id ,'union':'AND'},'id_person' !=   id_parameter })

it's possible to do something like that using angular-websql?
thank's

I would like to add a feature, and i'm interested in your opinion:

create table with reference to an other table
an orm mapping like

has many

createTable('article', {
   /* ...  */
  "comments" : {
     "type" : "HAS_MANY",
     "table": "comment"
      "field" : "ID_ARTICLE"
   }
});

then you could optionally load comments objects as an array in the user object

$scope.db.select("article", {"id" : 5}, {"comments" : true}).then(function(){
     console.log(results.rows.item(0).comments[0].name)
})

belong to

createTable('comment', {
   /* ...  */
  "article" : {
     "type" : "BELONG_TO",
     "table": "article"
      "field" : "ID_ARTICLE"
   }
});

$scope.db.select("comment", {"id" : 9}, {"article" : true})

I have to change all the funcions in my programs or simply to change the select function in angular-websql to check for null values in the select function to return selectAll instead.

Hi.

Here's my suggestion to implement order by.

I've made a simple and fast implementation, didn't send pull request cause I'm no sure if it's well formatted, or if it's better just implement another param in select, anyway, just keep the suggestion

selectOrder: function (b, c, o, od) {
                            if(!od)
                                od = "ASC";
                            var d = "SELECT * FROM `{tableName}` WHERE {where} ORDER BY {order} {direction};";
                            var a = this.whereClause(c);
                            return this.executeQuery(this.replace(d, {
                                "{tableName}": b,
                                "{where}": a.w,
                                "{order}": o,
                                "{direction}": od
                            }), a.p);
                        },             

Usage:

selectOrder(string tableName, object where, string field, string direction)

$scope.db.selectOrder("user", {
            "condition": 1
        }, "id",
        "ASC")
        .then(function (results) { 
                  for (i = 0; i < results.rows.length; i++) { 
                            console.log(results.rows.item(i));
                  }
        });

Hey man, first i want congratz you for share this!

I wanna ask if you could add Insert or replace in the source?

insertOrReplace: function(c, e) {
var f = "INSERT OR REPLACE INTO {tableName} ({fields}) VALUES({values});";
var a = "",
b = "",
v = [];
for (var d in e) {
a += (Object.keys(e)[Object.keys(e).length - 1] == d) ? "" + d + "" : "" + d + ", ";
b += (Object.keys(e)[Object.keys(e).length - 1] == d) ? "?" : "?, ";
v.push(e[d]);
}
return this.executeQuery(this.replace(f, {
"{tableName}": c,
"{fields}": a,
"{values}": b
}), v);
}

Hello,

I just discovered your api, and it looks great !

I was just wondering if it could be possible for you to add a method "createOrUpdateTable", which will create a table, if the table does not exist or if the fields are similar, but in case some fields are added, just dingo instead an 'ALTER TABLE ADD COLUMN'.

Do you think it could be possible to have something like this ?

Thanks a lot.
Cheers.

I came across this small issue today, when I tried to create a table containing columns without specifying the "null" property. Leaving out this property made the whole query fail silently.

e.g. for me this does not work at all:

$rootScope.db.createTable('events', {
    "uid": {
        "type": "INTEGER",
        "null": "NOT NULL",
        "primary": true
    },
    "title": {
        "type": "TEXT",
        "null": "NOT NULL"
    },
    // …
    "website": {
        "type": "TEXT"
    }
});

If I add "null": "NULL" to the website column definition, it works.

This behaviour is unexpected as allowing NULL should be the default (if not specified) besides it is not documented.

Anyway thanks for this useful module!

Hi

Thanks for the great library.

I needed to know if a table pre-exist in the database, couldn't see how to do it using your library so I added it in before createTable function:

tableExist: function(query){
var deferred = $q.defer();
db.transaction(function(tx) {
tx.executeSql("SELECT count(*) AS textist FROM sqlite_master WHERE type='table' AND name='"+query+"'", [], function(tx, results) {
var ex = results.rows.item(0).textist;
deferred.resolve(ex);
}, function(tx, e){
console.log("There has been an error: " + e.message);
deferred.reject();
});
});
return deferred.promise;
}

Use in code.

$scope.db.tableExist("tablename").then(function(result) {
if(result == 0){
console.log('No table found');
} else {
console.log('Table found');
}
});

Hope this helps someone :)

Could you provide an example of different types of oporators?

I've tried
db.select('categories', { "supcat_id": { "value": '<5' } }).then(function(results) { console.log(results.rows); })
but the query is always SELECT * FROM categories WHERE supcat_id = ?; with no results.

Hi,

i would like to know if i can do complex select? like:
select name, sum(orders) from orders group by name;

thank for your help

I'm using angular 1.4.8 and using select all rising infinite loop digest on angular ng-repeat
$scope.loadData = function () { $scope.db.selectAll("model").then(function (results) { $scope.data = results.rows; }); };

Hello,
I have problem when i try to update field with more dynamic parameter as condition

db.update("Table", {"notok": '1'}, {"id_person": {'value':id_person_dynamic_parameter  ,'union':'AND'},'id_element': id_second_dynamic_parameter});

i get this error

UPDATE `Table` SET `notok`= ? WHERE `id_person` undefined ? AND `id_element`=?;  ["1", "4377C91AF07E430E949C6E277B072787", 1] angular-websql.min.js:6

There has been an error: could not prepare statement (1 near "undefined": syntax error) 

Each field works when i update just one condition .

it's a bug or just it's impossible to update like that ?

Hello,

i have problem when i want update more fields.

            },
            {

            }
        ).then(function(){

        })

i have this error :

2014-07-31 11:43:48.293 23rc[49886:60b] UPDATE 'contacts' SET 'firstName'= ?'lastName'= ? WHERE 'id'=?; johne,doe,1

it's a bug or just it's impossible to update more fields ?

Hi

I wanted to try out the angular-websql but got an error with bower install:

ECONFLICT Unable to find suitable version for angular

I use Angular 1.3.13. Seems that the angular-websql runs only with Angular 1.2.x.
Is there an update planned to support newer versions of angular?

Thanks

Hello,
I actually use angular-websql perfectly with Goole Chrome browser.But that's not working with firefox.

var db;
db = $webSql.openDatabase('_db', '1.0', 'mydb DB', 2 * 1024 * 1024);
db.dropTable('_Table');
...

i have TypeError: db is undefined error when i call db's functions.
So do you have any idea about this case?
Thank's

Values coming from variables should be passed as parameters to overcome escaping problems.

e.g. instead of using

db.execute('INSERT INTO `{tableName}` ({fields}) VALUES({values})');

the values for each field should be represented with a '?' character and passed as a parameter to the execute()-function (dummy code ahead):

db.execute('INSERT INTO `{tableName}` ({fields}) VALUES(?, ?)', {values}[0], {values}[1]);

See this question on Stack Overflow for more information.
