SQLiteException：在UPDATE语句

无法识别的记号这是我的更新查询，SQLiteException：在UPDATE语句

ContentValues value = new ContentValues(); 
      value.put(DBhelper.Amount, txtBudget.getText().toString()); 



      db = helper.getWritableDatabase(); 

      db.update(DBhelper.TABLE1, value," "+DBhelper.Description+"='"+value_in_tv,null); 
      db.close(); 

      fetchData2(); 
      Toast.makeText(this, "Update Successfully", Toast.LENGTH_LONG).show(); 
      clearfield();

当单击该按钮来更新，它给致命异常错误。

value_in_tv这是我从另一个类得到了价值

Bundle data_from_list= getIntent().getExtras(); 
     value_in_tv= data_from_list.getString("passed data key"); 
     txr.setText(value_in_tv);

错误：

您在where子句中忘记关闭'：

db.update(DBhelper.TABLE1, value," "+DBhelper.Description+"='"+value_in_tv + "'",null)
