SQLite错误，找不到我的语法错误。代码1

Question

我想添加一个新的项目到我的数据库，我收到此错误消息。我试过了我能想到的一切。有什么我搞砸了吗？

这是实际提交数据并从editTexts和东西中抓取它们的onClick方法。

public void onSubmitClick(View view){ 

    productName = (EditText)findViewById(R.string.AddNew_editTextNameName); 
    productPalletName = (EditText)findViewById(R.string.AddNew_editTextPalletName); 
    productBrandName = (EditText)findViewById(R.string.AddNew_editTextBrandName); 
    productDatePurchased = (EditText)findViewById(R.string.AddNew_editViewDatePurchasedName); 
    productMisc = (EditText)findViewById(R.string.AddNew_editViewOtherName); 

    productType = (Spinner)findViewById(R.string.AddNew_spinnerTypeName); 
    productColor = (Spinner)findViewById(R.string.AddNew_spinnerColorCatName); 


    ProductsDataSource datasource = new ProductsDataSource(this); 
    datasource.open(); 

    if(isPallet){ 
     datasource.createProduct(productName.getText().toString(), productType.getId(), productColor.getId(), 
       productBrandName.getText().toString(), productPalletName.getText().toString(), prodPath, swatchPath, 
       productDatePurchased.getText().toString(), productMisc.getText().toString()); 
     datasource.close(); 
     Toast.makeText(this, "Creating New Product In Database", Toast.LENGTH_SHORT).show(); 
    } else{ 

     datasource.createProduct(productName.getText().toString(), productType.getSelectedItemPosition(), productColor.getSelectedItemPosition(), 
       productBrandName.getText().toString(), null, prodPath, swatchPath, 
       productDatePurchased.getText().toString(), productMisc.getText().toString()); 
     datasource.close(); 
     Toast.makeText(this, "Creating New Product In Database", Toast.LENGTH_SHORT).show(); 

    } 

    productListActivity(); 
    finish(); 
} 

这是实际创建项目的方法。我使用database.insert，我创建了SQL插入，试图解决我的问题。

public void createProduct(String productName, int productType, int productColor, String productBrand, 
      String productPalletName, String productProdPic, String productSwatchPic, String productDateOpened, String productMisc){ 

    ContentValues productValues = new ContentValues(); 
     //productValues.putNull(SQLiteHelper.colID);; //0 - written for order ease 
     productValues.put(SQLiteHelper.colName, productName); //1 
     productValues.put(SQLiteHelper.colType, productType);//2 
     productValues.put(SQLiteHelper.colPalletName, productPalletName); //3 
     productValues.put(SQLiteHelper.colBrand, productBrand); //4 
     productValues.put(SQLiteHelper.colColor,productColor);//5 
     productValues.put(SQLiteHelper.colProdPic, productProdPic);//6 
     productValues.put(SQLiteHelper.colSwatchPic, productSwatchPic); //7 
     productValues.put(SQLiteHelper.colDate, productDateOpened); //8 
     productValues.put(SQLiteHelper.colMisc, productMisc); //9 

      // Inserting Row 

      database.insert(productTable, null, productValues); 
      database.close(); // Closing database connection 

    /* database.execSQL("INSERT INTO "+ productTable + " (" + SQLiteHelper.colName + "," 
     + SQLiteHelper.colType + "," + SQLiteHelper.colColor + "," + SQLiteHelper.colBrand + 
     "," + SQLiteHelper.colPalletName + "," + SQLiteHelper.colProdPic + "," + SQLiteHelper.colSwatchPic 
     + "," + SQLiteHelper.colDate + "," + SQLiteHelper.colMisc + ") VALUES ('" + productName + "' , " + productType 
     + " , " + productColor + " ,'" + productBrand + "' , '" + productPalletName + "' , '" + productProdPic + "','" + 
     productSwatchPic + "'," + productDateOpened + ",'" + productMisc + "');"); 
     database.close(); */ 
    } 

这里是另一种方法，它是referencing-它与项目

public Cursor getAllProduct() { 
     List<Product> productsList = new ArrayList<Product>(); 

     Cursor cursor = database.query(SQLiteHelper.productTable, 
       allColumns, null, null, null, null, null); 

     cursor.moveToFirst(); 
     while (!cursor.isAfterLast()) { 
      Product product = cursorToProduct(cursor); 
      productsList.add(product); 
      cursor.moveToNext();   
      cursor.close(); 
     } 
     return cursor; 
    } 

的列表，如果你想它提供的列表视图，这里是表的创建

编辑：我不能回答我的问题再几个小时，所以我只是把这个位置的情况下，任何人有类似的问题：

如果你的数据库表现奇怪，而你在模拟器上，清理工作区并重新启动模拟器是不够的。删除完整的东西，并从SCRATCH开始（如果你已经附加了一个SD卡图像到模拟器，你可以保留它，只需从配置菜单中删除模拟器，并创建一个新的）模拟器

日志说这一切：没有列名为Product_Name。这应该告诉你：

• 检查它是否真的存在。如果您正在使用sqlite在仿真器或根源设备上进行测试，请尝试在外壳上运行.schema Products

• 确保您每次运行应用程序时都更新数据库版本，如果直接从eclipse安装。除非应用程序检测到数据库版本已升级，否则表格定义将不会反映出来。
