获取node.js中存储过程的结果

Question

Can I get multiple select from distinct tables (many rows) in just one store procedure in mysql and retrieve those result in nodejs?

Like in .NET with SQL Server we can use use "sqlnextresult"

IMAGE FROM STORE PROCEDURE

Here you have an example using mssql node package, you can find here the documentation about this package.

var sql = require('mssql'),
    connectionObj = {
        user: 'myUser',
        password: 'myPassword',
        server: 'http://mysqlserver.whatever'
        options: {
            database: 'myDB'
        }
    };

/**
 * Opens connection to sql server.
 *
 * @return {Object} Connection object.
 */
function openConnection() {
    var connection = new sql.Connection(connectionObj);
    return connection;
};

/**
 * Closes connection.
 *
 * @param {Object} connection - Connection Object.
 * @return {Promise} Promise.
 */
function closeConnection(connection) {
    return connection.close();
};

/**
 * Does a request to sql server.
 *
 * @param {Object} connection - Connection object.
 * @param {string} query - Query string to compute.
 * @return {Promise} Promise.
 */
function doRequest(connection, query) {
    return connection.request().query(query);
};

/**
 * Gets Request.
 *
 * @param {Object} connection - Connection object.
 */
function getRequest(connection) {
    return new sql.Request(connection);
};

var request, conn = openConnection();

// First open the connection with DB (method uses the object created at the begining.
conn.connect()
    .then(function() {
        // Now creates a Request.
        request = getRequest(conn);
        // Executes your stored procedure.
        return request.execute('usp_get_Masters');
    })
    .then(function(result) {
        console.log(result); // Here in result you have the result of the stored procedure execution.
    })
    .catch(function(error) {
        console.log(error);
    });
