Execute raw query on MySQL

How is it possible to execute raw query and expose results through REST API with strongloop?

I've read something about using hooks and dataSource.connector.query() but I cannot find any working examples.

Here is a basic example. If you have a Product model (/common/models/product.json), extend the model by adding a /common/models/product.js file:

module.exports = function(Product) {

    Product.byCategory = function (category, cb) {

        var ds = Product.dataSource;
        var sql = "SELECT * FROM products WHERE category=?";

        ds.connector.query(sql, category, function (err, products) {

            if (err) console.error(err);

            cb(err, products);

        });

    };

    Product.remoteMethod(
        'byCategory',
        {
            http: { verb: 'get' },
            description: 'Get list of products by category',
            accepts: { arg: 'category', type: 'string' },
            returns: { arg: 'data', type: ['Product'], root: true }
        }
    );

};

This will create the following endpoint example: GET /Products/byCategory?group=computers

  1. expose a remote method in your /common/models/model.js
  2. execute the sql query in the remote method (via dataSource.connector.query(sql, cb);
