Erhalten Sie das Ergebnis der gespeicherten Prozedur in node.js

Question

Kann ich mehrere aus verschiedenen Tabellen (viele Zeilen) in nur einer Speicherprozedur in mysql auswählen und diese Ergebnisse in Nodejs abrufen?

Wie in .NET mit SQL Server können wir nutzen "sqlnextresult"

IMAGE FROM STORE PROCEDURE

Hier haben Sie ein Beispiel mit mssql Knoten Paket verwenden, können Sie here in der Dokumentation zu diesem Paket finden.

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); 
    });
