ER_PARSE_ERROR更新與MySQL和nodejs查詢

Question

我已經看過類似的其他問題，但我似乎無法找到我的問題或解決它。請幫忙。

我在做什麼是將輸入數據從客戶端傳遞到服務器，以便它可以更新ID匹配的某個或某些行。我嘗試了不同的方式來獲取傳遞給查詢的ID，但我仍然以ER_PARSE_ERROR結束。

路線

app.post('/configuration_materials/editsend/:id', isLoggedIn, materialpricingTable.UPDATEMaterial); 

客戶端/ jQuery和AJAX功能

$(function() { 



    $('body').on('click', '.SubmitEditMat', function() { 

     var materialIDedit     = this.id.split('-')[1]; 


     var clientMtrlApplication  = $('#clientMtrlApplication'); 
     var clientMtrlType    = $('#clientMtrlType'); 
     var clientMtrlSpec    = $('#clientMtrlSpec'); 
     var clientPricePerSheetORFt  = $('#clientPricePerSheetORFt'); 
     var clientSqFtofSheetORLen  = $('#clientSqFtofSheetORLen'); 
     var clientWtPerFt    = $('#clientWtPerFt'); 
     var clientWtPerItem    = $('#clientWtPerItem'); 
     var clientMtrlPricePerFt  = $('#clientMtrlPricePerFt'); 
     var clientMtrlPricePerLb  = $('#clientMtrlPricePerLb'); 
     var clientMtrlPricePerItem  = $('#clientMtrlPricePerItem '); 
     var clientLaborHrsPerFt   = $('#clientLaborHrsPerFt'); 
     var clientLaborHrsPerItem  = $('#clientLaborHrsPerItem'); 
     var clientNotes     = $('#clientNotes'); 

     var divAddMatSuccess   = $('#modifiedModalEditMat'); 


     $.ajax({ 
      url: '/configuration_materials/editsend/' + materialIDedit, 
      method: 'POST', 
      contentType: 'application/json', 
      data: JSON.stringify({ 

       serverMtrlApplication:  clientMtrlApplication.val(), 
       serverMtrlType:    clientMtrlType.val(), 
       serverMtrlSpec:    clientPricePerSheetORFt.val(), 
       serverPricePerSheetORFt: clientPricePerSheetORFt.val(), 
       serverSqFtofSheetORLen:  clientSqFtofSheetORLen.val(), 
       serverWtPerFt:    clientWtPerFt.val(), 
       serverWtPerItem:   clientWtPerItem.val(), 
       serverMtrlPricePerFt:  clientMtrlPricePerFt.val(), 
       serverMtrlPricePerLb:  clientMtrlPricePerLb.val(), 
       serverMtrlPricePerItem:  clientMtrlPricePerItem.val(), 
       serverLaborHrsPerFt:  clientLaborHrsPerFt.val(), 
       serverLaborHrsPerItem:  clientLaborHrsPerItem.val(), 
       serverNotes:    clientNotes.val() 
      }), 

      success: function(response) { 
       console.log(response); 


       divAddMatSuccess.html(''); 

       divAddMatSuccess.append('\ 
       <div class="alert alert-success">\ 
       <strong>Success! Updated: </strong> ' + clientMtrlApplication.val() + clientMtrlType.val() + clientMtrlSpec.val() +'\ 
       </div>\ 
       '); 


      } 


     }); 



    }); 
}); 

服務器端，materialpricingTable.js與UPDATEMaterial和MySQL查詢

//查詢

exports.sqlEditMaterial = "UPDATE generictablenamepleaseignore SET ? where ID = ?;"; 

// UPDATEMaterial功能

exports.UPDATEMaterial = function (req, res) { 
    var weErrored = false; 

    var idOfMaterial = req.params.id; 


    var post = { 

     // NAMEINDATABASE: NAMEONFORM 
     Application: req.body.serverMtrlApplication, 
     MaterialType: req.body.serverMtrlType, 
     MtrlSpecs: req.body.serverMtrlSpec, 
     PricePerSheetORFt: req.body.serverPricePerSheetORFt, 
     SqFtofSheetORLength: req.body.serverSqFtofSheetORLen, 
     WtPerFt: req.body.serverWtPerFt, 
     WtPerItem: req.body.serverWtPerItem, 
     MtrlPricePerFt: req.body.serverMtrlPricePerFt, 
     MtrlPricePerLb: req.body.serverMtrlPricePerLb, 
     MtrlPricePerItem: req.body.serverMtrlPricePerItem, 
     LaborHrsPerFt: req.body.serverLaborHrsPerFt, 
     LaborHrsPerItem: req.body.serverLaborHrsPerItem, 
     Notes: req.body.serverNotes 
    }; 

    var sendData = post + idOfMaterial; 

    mySqlController.connection.query(exports.sqlEditMaterial, sendData , 
     function (err) { 
      if (err) { 
       console.log(err.code); 
       weErrored = true; // setting the error to true, this is used to display a message on the front end 

      } 

      res.send('Success!'); 


     }); 
}

您不能使用+運營商與對象（例如post）。在這個特定的情況下，需要傳遞的陣列與所述兩個值來代替：

var sendData = [post, idOfMaterial]; 

此外，在SQL查詢的最後的分號是不必要的，並使用命令行MySQL客戶端（當只需要或者當在單個查詢中執行多個語句時）。
