Unable to print array in node.js

Here is my code in routes

router.get('/chkjson', function(req, res, next) {
    req.getConnection(function(err,connection){
        var ItemArray = [];
        var myset = [];

        var query = connection.query('SELECT `db_name` FROM `database`',function(err,rows)
        {
            ItemArray.push({
                allDb : []
            });
            var k=0;
            for (var i in rows) {
                    retset = JSON.stringify(rows[i]);
                    var jsonset =  JSON.parse(retset);
                    console.log(ItemArray);
                    console.log("========");
                    myset.push(ItemArray);
                    ItemArray[0].allDb.push(jsonset.db_name);
            }
        });
        console.log(myset);   //blank array
        console.log("-----");
        console.log(ItemArray);   //blank array
        console.log("-----");
            res.render( 'new/post-select-table', 
                { 
                    title: 'Select Database',
                    session_store:req.session,
                });
        });
});

I'm getting blank array when I'm trying to print array outside for loop. Can anyone help me where im going wrong.
