将 Cordova 混合应用连接到 Azure SQL 数据库

Question

我正在使用 Visual Studio 2015 中的 Apache Cordova 和 Ionic Framework 创建混合应用程序。

我想将我的应用程序连接到云 SQL 数据库，例如 Azure SQL 或 Google Cloud SQL。

我需要能够执行插入、更新和选择操作。

根据我的研究，我了解到可能需要使用 PHP，但我没有找到任何好的示例可供参考。非常感谢您的帮助。

步骤1：连接 使用新的Connection函数连接到SQL数据库。 JavaScript

var Connection = require('tedious').Connection;  
var config = {  
    userName: 'yourusername',  
    password: 'yourpassword',  
    server: 'yourserver.database.windows.net',  
    // If you are on Microsoft Azure, you need this:  
    options: {encrypt: true, database: 'AdventureWorks'}  
};  
var connection = new Connection(config);  
connection.on('connect', function(err) {  
// If no error, then good to proceed.  
    console.log("Connected");  
});  

步骤2：执行查询 所有的SQL语句都是使用新的Request()函数执行的。如果语句返回行，比如select语句，您可以使用request.on()函数检索它们。如果没有行，request.on()函数返回空列表。 JavaScript

var Connection = require('tedious').Connection;  
var config = {  
    userName: 'yourusername',  
    password: 'yourpassword',  
    server: 'yourserver.database.windows.net',  
    // When you connect to Azure SQL Database, you need these next options.  
    options: {encrypt: true, database: 'AdventureWorks'}  
};  
var connection = new Connection(config);  
connection.on('connect', function(err) {  
    // If no error, then good to proceed.  
    console.log("Connected");  
    executeStatement();  
});  

var Request = require('tedious').Request;  
var TYPES = require('tedious').TYPES;  

function executeStatement() {  
    request = new Request("SELECT c.CustomerID, c.CompanyName,COUNT(soh.SalesOrderID) AS OrderCount FROM SalesLT.Customer AS c LEFT OUTER JOIN SalesLT.SalesOrderHeader AS soh ON c.CustomerID = soh.CustomerID GROUP BY c.CustomerID, c.CompanyName ORDER BY OrderCount DESC;", function(err) {  
    if (err) {  
        console.log(err);}  
    });  
    var result = "";  
    request.on('row', function(columns) {  
        columns.forEach(function(column) {  
          if (column.value === null) {  
            console.log('NULL');  
          } else {  
            result+= column.value + " ";  
          }  
        });  
        console.log(result);  
        result ="";  
    });  

    request.on('done', function(rowCount, more) {  
    console.log(rowCount + ' rows returned');  
    });  
    connection.execSql(request);  
}  

步骤三：插入行 在这个例子中，您将看到如何安全地执行INSERT语句，传递参数以保护您的应用程序免受SQL注入漏洞，并检索自动生成的主键值。 JavaScript

var Connection = require('tedious').Connection;  
var config = {  
    userName: 'yourusername',  
    password: 'yourpassword',  
    server: 'yourserver.database.windows.net',  
    // If you are on Azure SQL Database, you need these next options.  
    options: {encrypt: true, database: 'AdventureWorks'}  
};  
var connection = new Connection(config);  
connection.on('connect', function(err) {  
    // If no error, then good to proceed.  
    console.log("Connected");  
    executeStatement1();  
});  

var Request = require('tedious').Request  
var TYPES = require('tedious').TYPES;  

function executeStatement1() {  
    request = new Request("INSERT SalesLT.Product (Name, ProductNumber, StandardCost, ListPrice, SellStartDate) OUTPUT INSERTED.ProductID VALUES (@Name, @Number, @Cost, @Price, CURRENT_TIMESTAMP);", function(err) {  
     if (err) {  
        console.log(err);}  
    });  
    request.addParameter('Name', TYPES.NVarChar,'SQL Server Express 2014');  
    request.addParameter('Number', TYPES.NVarChar , 'SQLEXPRESS2014');  
    request.addParameter('Cost', TYPES.Int, 11);  
    request.addParameter('Price', TYPES.Int,11);  
    request.on('row', function(columns) {  
        columns.forEach(function(column) {  
          if (column.value === null) {  
            console.log('NULL');  
          } else {  
            console.log("Product id of inserted item is " + column.value);  
          }  
        });  
    });       
    connection.execSql(request);  
}

您好，Cordova是一个基于Node.js的框架。您可以使用Azure SQL数据库与Node.js进行开发。以下是一些优秀的驱动程序选项，可帮助您在所选平台上快速入门：
- node-mssql
- tedious

这里有一个快速的代码示例：

var Connection = require('tedious').Connection;  
var config = {  
    userName: 'yourusername',  
    password: 'yourpassword',  
    server: 'yourserver.database.windows.net',  
    // When you connect to Azure SQL Database, you need these next options.  
    options: {encrypt: true, database: 'AdventureWorks'}  
};  
var connection = new Connection(config);  
connection.on('connect', function(err) {  
    // If no error, then good to proceed.  
    console.log("Connected");  
    executeStatement();  
});  

var Request = require('tedious').Request;  
var TYPES = require('tedious').TYPES;  

function executeStatement() {  
    request = new Request("SELECT c.CustomerID, c.CompanyName,COUNT(soh.SalesOrderID) AS OrderCount FROM SalesLT.Customer AS c LEFT OUTER JOIN SalesLT.SalesOrderHeader AS soh ON c.CustomerID = soh.CustomerID GROUP BY c.CustomerID, c.CompanyName ORDER BY OrderCount DESC;", function(err) {  
    if (err) {  
        console.log(err);}  
    });  
    var result = "";  
    request.on('row', function(columns) {  
        columns.forEach(function(column) {  
          if (column.value === null) {  
            console.log('NULL');  
          } else {  
            result+= column.value + " ";  
          }  
        });  
        console.log(result);  
        result ="";  
    });  

    request.on('done', function(rowCount, more) {  
    console.log(rowCount + ' rows returned');  
    });  
    connection.execSql(request);  
}
