Nodejs使用tedious驱动模块连接SqlServer

app.js代码如下:

var Connection = require('tedious').Connection;
var mongoose = require('mongoose');
var rows = [];

//用户名，密码和数据库服务器,数据库
var config = {
userName: 'sa',
password: '123456',
server: '127.0.0.1',
options : {
database  : 'BigDataTest'
}
};

var connection = new Connection(config);
var Request = require('tedious').Request;

connection.on('connect', function(err) {
//错误处理
if(err)
{
console.log("连接出错!");
}
else {
{
console.log("连接成功!");
};
}
getSqlData();
});

function getSqlData()
{
console.log('从SQL获取数据');
request = new Request("SELECT * FROM Citys", function(err, rowCount)
{
if (err)
{
console.log(err);
}
else
{
console.log("行数: " + rowCount);
//遍历对象数组，查出数据
// rows.forEach(function(r){
// console.log(r["name"]+"---"+r["code"]);
// })
}
});

request.on('row', function(columns)
{
var row = {};
columns.forEach(function(column)
{
row[column.metadata.colName] = column.value;
});
rows.push(row);

});

connection.execSql(request);

}

sqlserver  建表脚本:

CREATE TABLE [dbo].[Citys](
[id] [int] IDENTITY(1,1) NOT NULL,
[name] [nvarchar](100) NULL,
[code] [varchar](300) NULL,
CONSTRAINT [PK_Citys] PRIMARY KEY CLUSTERED
(
[id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

GO

SET ANSI_PADDING OFF
GO

结果如图:
