在node.js中獲取存儲過程的結果

Question

我可以在mysql的一個存儲過程中從不同的表（多行）中選擇多個select並在nodejs中檢索這些結果嗎？

就像在與SQL Server，我們可以使用使用「sqlnextresult」 .NET

IMAGE FROM STORE PROCEDURE

在這裏，你可以選擇使用mssql節點封裝的例子，你可以找到here這個包的文檔。

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); 
    });
