shrinksqlite3.js

var sqlite3=require('sqlite3');
var pgu={
    db: {},
    res: {},
    all: function (topic,bind=[]){
		this.db.all(topic, bind, function(err, row) {
			if (err) { console.log(err,msg); return null;}
			else {
				this.res=row;
				console.log(JSON.stringify(this.res));
				this.factorize(topic,bind);
			}
		}.bind(this));
	},
	factorize: function (topic,bind=[]){
		var rows= this.res;
		console.log(JSON.stringify(this.res));
		if(rows!==undefined && rows!==null && rows.length>0){
			var colnames = Object.keys(rows[0]);
			var arows = [];
			for(var i=0; i<rows.length; i++){
				var trow=[];
				for(var j=0; j<colnames.length;j++){
					trow.push(rows[i][colnames[j]]);
				}
				arows.push(trow);
			}
			this.res = {"columns":colnames,"values":arows};
		}
	}
};

pgu.db = new sqlite3.Database('Northwind.sqlite');
pgu.all("select * from customer");
if(pgu.res!==null){
	console.log(JSON.stringify(pgu.res));
}
