QUESTION
Today has been quite challenging so I can't think of any new ideas anymore so the solution to this question may be quite obvious to you. I have a very simple data frame like bellow:

QUESTION
I am having a hard time understanding why the Oracle CBO is behaving the way it does when a bind variable is part of a OR condition.
My environment
Oracle 12.2 over Red Hat Linux 7
HINT. I am just providing a simplification of the query where the problem is located
...ANSWER
Answered 2021-Jun-10 at 17:36From the execution plan the optimiser is, for some reason, re-evaluating the hierarchical query for every row in your table, and then using exists()
to see if that row's ID is in the result. It isn't clear why the or
is causing that. It might be something to raise with Oracle.
From experimenting I can see three ways to at least partially work around the problem - though I'm sure there are others. The first is to move the CSV expansion to a CTE and then force that to materialize with a hint:
QUESTION
Whenever I fetch data from any server to display it in ag-grid, ag-grid does not maintain the column order for the column that uses valueGetter to choose the value and puts that column automatically at the end.
The problem is replicated in the following code sandbox link: https://codesandbox.io/s/ag-grid-column-ordering-bug-bz055 as a minimum reproducible example
The data received from the server is in the following format
...ANSWER
Answered 2021-Jun-11 at 14:48Since the column does not have a field
supplied, I'd recommend either supplying a field
or colID
to the column. This would be the simplest approach without having to use any API calls to move the column:
QUESTION
I've had a lot of issues with this application because I am simply not good enough yet, but I am almost done with it and just want to finish it so I can move on to some slightly lower level projects.
It is a tkinter to-do application.
You can add a Task to a listbox
For every Task
, there are some associated attributes, among others: ````self.value = vand
self.connectivity = c. The hierarchy of the tasks displayed in the listbox is determined by the value of
val_var``` (e.g. the higher the value the higher on the list it will be displayed).
The Task and the associated attributes are determined by the user's input when one creates another task.
The Task
is appended to a list task_list
and after the user has added more than 1 task to the list, the next time one adds a task one will have the option to check existing tasks that it is connected with somehow.
The list is sorted so the task with the highest value (val_var
) is displayed at the top of the Listbox and the task with the lowest value is displayed at the bottom of the Listbox.
You can "Save tasks" and then launch the application at a later time where you can then "Load tasks".
Issue 1:
After loading tasks from a saved .dat file, it displays in the Listbox in the order it was saved in. However, if you now want to add another task at least two undesirable things happen:
- The tasks now loaded into the Listbox are now not displayed as checkbuttons upon adding a new task.
- When you add another task (again this is after loading the .dat file) the Listbox will delete what was just loaded and the Listbox will only display the newly added task.
I am somehow interested in being able to load the Tasks
instances from the .dat file and then append them to the task_list so they are a part of the current session/instance of the application, but I don't know how one might do that.
Issue 2:
On a given session where tasks have been added to the Listbox, they can be deleted from the listbox using the "Delete task" button. The selected task in the Listbox is deleted, but it is not the same task that is deleted from the task_list
.
To test what I mean by this one can add a couple of tasks to the Listbox and then delete one after doing so. Notice upon trying to create yet another new task that the one just deleted from the Listbox will still be shown as a checkbutton - however, another task that wasn't just deleted has now vanished as a checkbutton.
Any help with these issues will be sincerely appreciated.
Here's the code:
...ANSWER
Answered 2021-Jun-11 at 04:24Your problem is fairly simple. You need to save the objects of the Task
class instead of saving the strings present inside the Listbox.
That said you should never give bare except clause like the one you did, always specify the exception you want to catch. You will find it hard to find the exact problem if you don't.

To begin this topic off I've created a stock market environment that a function can return its observation through this function.

I want to be able to take data that's in the same format but from different sources and concatenate the rows, but to keep track of the source of the data I'd like to also introduce a source column.

QUESTION
I am using BeautifulSoup to extract information from [http://financials.morningstar.com/company-profile/c.action?t=AAPL][1]
Especially, the 'CIK' field from the 'Operation Details' section as shown in the [image][1]
This is the code I have used:
```page = requests.get('http://financials.morningstar.com/company-profile/c.action?t=AAPL')```
```soup = BeautifulSoup(page.content, 'html5lib')```
```div = soup.find(name='div',attrs={'id':'OperationDetails'}) ```
Upon ```print(div)``` I get an empty tag output.
However, upon inspecting the page the 'div' tag with **id='OperationDetails'** does have child tags under it. Am I missing something here?
I am a beginner in using BeautifulSoup and I was practicing on this website. What is wrong and how do I now get the 'table' element that has the information (CIK) I am looking for?
Sincere thanks.
