我在Visual Studio 2015中使用apache cordova和离子框架来创建混合应用程序.
我想将我的应用程序连接到云sql数据库,如azure sql或google cloud sql.
我需要能够进行插入,更新和选择.
根据我的研究,我明白我可能不得不使用PHP,但我没有找到任何好的例子.任何帮助深表感谢.

第1步:连接
新的Connection函数用于连接SQL数据库.
JavaScript的
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");
});
第2步:执行查询
所有SQL语句都使用新的Request()函数执行.如果语句返回行,例如select语句,则可以使用request.on()函数检索它们.如果没有行,request.on()函数返回空列表.
JavaScript的
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);
}
第3步:插入一行
在此示例中,您将了解如何安全地执行INSERT语句,传递保护应用程序免受SQL注入漏洞影响的参数,以及检索自动生成的主键值.
JavaScript的
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);
}
