nodejs連線sqlserver遇到的問題

首先，我用了mssqlheper模組，但是死活連不上資料庫，於是放棄，選擇了mssql模組。

**如下：

var mssql = require('mssql');  

var db = {};  
var config = ;server=#\\sql;database=#;uid=#;pwd=#;",  
/*    options: ,*/  
pool:   
}; db.sql = function (sql, callback)   
var ps = new mssql.preparedstatement(connection);  
ps.prepare(sql, function (err)   
ps.execute('', function (err, result)   
ps.unprepare(function (err)   
callback(err, result);  
});  
});  
});  
});  
};  
module.exports = db;

var express = require('express');  

var db = require('./db');  
const request = require('request-json');
var client = request.createclient('');
var lastid = 0;
var timebw = 1 * 1000;
class postdata 
else 
// 當讀取到最後一條且大於50條時，lastid減50。
if (lastid = lastid && lastid > 50) });
}_postdate(item, fc) ;
postdata['creator_id'] = item['\u5e8f\u53f7'];
postdata['weight_id'] = 'code002';
postdata['weight_code'] = 'code002';
postdata['weight_rfid'] = '0';
postdata['veh_id'] = item['\u6d41\u6c34\u53f7'];
postdata['car_no'] = item['\u8f66\u53f7'];
postdata['weight_gross'] = item['\u6bdb\u91cd'];
postdata['weight_veh'] = item['\u76ae\u91cd'];
postdata['weight_net'] = item['\u51c0\u91cd'];
postdata['garbage_type'] = item['\u8d27\u540d'];
postdata['weight_date'] = item['\u76ae\u91cd\u65f6\u95f4'];
postdata['delivery_unit'] = item['\u53d1\u8d27\u5355\u4f4d'];
postdata['prj_id'] = 2;
postdata['tcar_company_id'] = 0;
postdata['creator_id'] = item['\u5e8f\u53f7'];
console.log('post data', postdata);
client.post('/jsonapi/cancu_weight/add.json',
postdata, function (err, res, body) 
else );
}});
}_time(fc) );
return;
}_self._postdate(d[0], fc);})}
run(fc) , timebw);
}, timebw)
}}var t = new postdata();
t.run();

無力解決，只好在網上查詢其他的方法，終於又找到了tedious模組，**如下：

const connection = require('tedious').connection;    

const request = require('tedious').request;    
exports.mssql = function(config);    
connection.on('connect', function(err));    
}else;    
callback(err,rows);    
//  connection.close();    
});    
var n=0;                        
request.on('row', function(columns) ;    
columns.foreach(function(column) );    
n++;    
});    
connection.execsql(request);                                 //執行sql語句    
}    
});    
}    
}

const request = require('request-json');

var client = request.createclient('');
var mssql = require('./tedious.js');
var conn = new mssql.mssql( });
var lastid = 0;
var timebw = 1 * 1000;
class postdata 
else });
}_postdate(item, fc) ;
postdata['creator_id'] = item['\u5e8f\u53f7'];
postdata['weight_id'] = 'code002';
postdata['weight_code'] = 'code002';
postdata['weight_rfid'] = '0';
postdata['veh_id'] = item['\u6d41\u6c34\u53f7'];
postdata['car_no'] = item['\u8f66\u53f7'];
postdata['weight_gross'] = item['\u6bdb\u91cd'];
postdata['weight_veh'] = item['\u76ae\u91cd'];
postdata['weight_net'] = item['\u51c0\u91cd'];
postdata['garbage_type'] = item['\u8d27\u540d'];
postdata['weight_date'] = item['\u76ae\u91cd\u65f6\u95f4'];
postdata['delivery_unit'] = item['\u53d1\u8d27\u5355\u4f4d'];
postdata['prj_id'] = 2;
postdata['tcar_company_id'] = 0;
postdata['creator_id'] = item['\u5e8f\u53f7'];
console.log('post data', postdata);
client.post('/jsonapi/cancu_weight/add.json',
postdata, function (err, res, body) 
else );
}});
}_time(fc) );
return;
}_self._postdate(d[0], fc);})}
run(fc) , timebw);
}, timebw)
}}var t = new postdata();
t.run();

找不到什麼原因，接下來會繼續找原因
