I want to join four tables, I wrote in many possible ways but I get an error of unknown column and I don't get what's wrong.

This is what I write:

I'm making Car parking system, and I have some difficulities with SQL database. I'm selecting data from SQL database, but I need to get the time correctly that I could use it for further calculations. So for example I need to get the time that was inserted to database as VARCHAR, maybe the bad thing is that I needed to use other method as TIME, but that's not the case. The thing I need is to use this line Started_Parking = row [3]. This should get the time from database and after that, I should be able to see the time difference from the start when car was registered and current time. By doing that I should be able to calculate the sum which the "User" should pay for parking. So by short I just need to somehow get the time from database and use it for calculations. Here's my code, I also get errors when compiling :

Error while fetching data from PostgreSQL unsupported operand type(s) for -: 'datetime.datetime' and 'str'

I'm learning python and I've come across this problem that seems very simple, but I can't find a way

I have two lists:

I receive a Person object from an API that has a list of another object as one of it's attributes. I receive the following error in the logs: "Expexted BEGIN_ARRAY but was BEGIN_OBJECT at path $". So the JSON is not parsing the list correctly. I use Moshi for JsonParsing.

The Person JSON object: (In the real project there are multiple persons)

The task I'm trying to implement is finding Collatz sequence for numbers in a set interval using several threads and seeing how much improvement is gained compared to one thread.

However one thread is always faster no matter if it I choose 2 threads(edit. 2 threads are faster, but not by much while 4 threads is slower than 1 thread and I have no idea why.(I could even say that the more threads the slower it gets). I hope someone can explain. Maybe I'm doing something wrong.

Below is my code that I wrote so far. I'm using ThreadPoolExecutor for executing the tasks(one task = one Collatz sequence for one number in the interval).

The Collatz class:

With function laisviLaikai() I'm trying to disable check input when I choose a date, and it works fine, but when I change date these inputs are still disabled.

So I write a code to handle that. When function is called the code have to enable all check inputs, but it not working.

This is Html my code:

I am new to Google script and I want to create a script that bring the image name from spreadsheet and insert that image in google docs. My problem is the names of images. In spreadsheet they are stored with the same text in the start 'testui/'. I need to delete it from beginning. Tried used replaceText('testui/', ''), but got message - TypeError: Cannot find function replaceText in object testui/01-03-2019 11-02-14.Signature.054223.png

I cannot find solution to highlight matches in PHP with ignoring UTF8 symbols.

Code example:
