Global SQL Error Logging

Hi,

I am working on an app that uses SQLite db using Titanium Appcelerator Alloy framework.

Here's one of my models: customer_order_queue.js

exports.definition = {
    config: {
        "columns": {
            "QueueId":"INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL UNIQUE",
            "CustomerId":"INTEGER",
            "BasketData":"TEXT", // JSON Encoded Sku, Name, Qty, Price Array
            "OrderCurrency":"TEXT",
            "PaymentMethod":"TEXT",
            "ShippingMethod":"TEXT",
            "ShippingMethodTitle":"TEXT",
            "Subtotal":"REAL",
            "ShippingAmount":"REAL",
            "TaxAmount":"REAL",
            "CurrencyRate":"REAL",
            "TaxRate":"REAL",
            "GrandTotal":"REAL",
            "Status":"TEXT", // Pending OR Error OR Synced
            "LastError":"TEXT"
        },
        "adapter": {
            "type":"sql",
            "collection_name":"customer_order_queues",
            "db_name":"myApp",
            "idAttribute":"QueueId"
        }
    },
    extendModel : function(Model) {
        _.extend(Model.prototype, {
        });
        return Model;
    },
    extendCollection : function(Collection) {
        _.extend(Collection.prototype, {
            executeQuery : function(sqlStatement) {
                db = Ti.Database.open(this.config.adapter.db_name);
                db.execute(sqlStatement);
                db.close(); db = null;
                this.trigger('sync');
            },
            deleteAll : function() {
                db = Ti.Database.open(this.config.adapter.db_name);
                db.execute('DELETE FROM '+ this.config.adapter.collection_name);
                db.execute('DELETE FROM sqlite_sequence where name = \''+ this.config.adapter.collection_name +'\'');
                db.close(); db = null;
                this.trigger('sync');
            }
        });
        return Collection;
    }
};

> invalid SQL Statement at Customer_order_queue.js (line 1)

Can anyone see anything wrong with this model?

Anyway, my question was, is it possible to have some sort of global error logging for all SQL errors? So I can see when SQL errors occurred, the last statement and the error message?
