SyntaxError：missing）在javascript中的參數列表後

Question

這是錯誤，但我無法找到它。從phpMyAdmin的SQL控制檯運行時，運行查詢FINT

var query = connection.query('Select distinct a.*, IFNULL(b.scannerid,'Not Available') AS `scannerid`, IFNULL(date(b.datetime),'Not Available') as datetime, IFNULL(b.status,'Absent') AS `status` from studentdetails a LEFT OUTER JOIN discovereddevices b ON a.bluetoothid = b.blueid and date (b.datetime) = CURRENT_DATE',function(err,rows) 

錯誤：

SyntaxError: missing) after argument list 
     at createScript (vm.js:53:10) 
     at Object.runInThisContext (vm.js:95:10) 
     at Module._compile (module.js:543:28)

     at require (internal/module.js:20:19) 
     at Object.<anonymous> (/home/ubuntu/Attendance system/app.js:13:24) 

的JavaScript代碼：

exports.getattendance = function(req, res){ 

     req.getConnection(function(err,connection){ 
       var query = connection.query('Select distinct a.*, 
      IFNULL(b.scannerid,'Not Available') AS `scannerid`, 
      IFNULL(date(b.datetime),'Not Available') as datetime, 
      IFNULL(b.status,'Absent') AS `status` from studentdetails a LEFT OUTER 
      JOIN discovereddevices b ON a.bluetoothid = b.blueid and date (b.datetime) 
      = CURRENT_DATE',function(err,rows) 
       { 
        if(err) 
         console.log("Error Selecting : %s ",err); 
        res.render('showreport',{page_title:"Attendance Report Generated",data:rows}); 

       }); 

       //console.log(query.sql); 
      }); 

     }; 

Answer 1

行情使用反引號 嘗試錯誤使用（`）

例如：

exports.getattendance = function(req, res){ 

    req.getConnection(function(err,connection){ 
      var query = connection.query(`Select distinct a.*, IFNULL(b.scannerid,'Not Available') AS 'scannerid', IFNULL(date(b.datetime),'Not Available') as datetime, IFNULL(b.status,'Absent') AS 'status' from studentdetails a LEFT OUTER JOIN discovereddevices b ON a.bluetoothid = b.blueid and date (b.datetime) = CURRENT_DATE()`, 
      function(err,rows) 
       if(err) 
        console.log("Error Selecting : %s ",err); 
       res.render('showreport',{page_title:"Attendance Report Generated",data:rows}); 

      }); 

      //console.log(query.sql); 
     }); 

    }; 

編輯：

而且CURRENT_DATE（）應該是一個功能！
