Answer 1

You have two handlers for the path /RestaurantDesc/ - only one should be kept.

In your query, the syntax is wrong.

Assuming you have a table that looks like this (change these names to match your schema):

Table Name: Restaurant
    column:       name

And you are using node-mysql, Change your query to something like this:

connection.query('SELECT * FROM Restaurant where name = ?', [keyName], function (err, rows, fields) {
    console.log('Connection result error ' + err);
    name_of_restaurants = rows;
    callback();
});

The ? is a place holder for values passed in the array of values passed in the second parameter to query.

See: Escaping query values for more information on how this works. Short answer though is that the values will be escaped properly using this approach.
