cookie-parser у тебя импортируется но не используется.

const cookies = require('cookie-parser');
app.use(cookies())

У вас запрос чутка неправильный собирается, примерно такой:

select * from table where 1 and where 2 and where 3

ps.

if(req.cookies.vprodaj=='checked'){
    otherwhere=otherwhere+' AND WHERE count>0 ';
}
if(req.cookies.soskidkoi=='checked'){
    otherwhere=otherwhere+' AND WHERE (`price` -`price` / 100 * `sale`) >0 ';
}

var firsrtString = 'hello';
var secondString = 'hello';

firsrtString = firsrtString + ' world';
secondString += ' world';

alert(firsrtString === secondString);
