Я скачал простую систему инвентаризации python. В ней было 3 столбца: название продукта, количество продукта и цена продукта, которые я просмотрел, и добавил местоположение продукта везде, где в программе присутствовали другие 3 продукта, количество продукта и цена продукта. Теперь, когда он запускается, я получаю эту ошибку: sqlite3.OperationalError: у таблицы product нет столбца с именем product_location
Кто-то предложил удалить IF NOT EXISTS, FROM (CREATE TABLE IF NOT EXISTS), но это не сработало.
PASSWORD = StringVar()
PRODUCT_NAME = StringVar()
PRODUCT_PRICE = IntVar()
PRODUCT_QTY = IntVar()
PRODUCT_LOCATION = IntVar()
SEARCH = StringVar()```
I downloaded python simple inventory system from ```https://www.sourcecodester.com/tutorials/python/11417/python-simple-inventory-system.html.```
It had 3 columns: product name, product quantity and product price.
I want to use at work but I need product location as well. I went through and added product location everywhere the other 3 were in the program. There were some other things I changed but don’t recall all of them.
Now when it runs I get this error:
```sqlite3.OperationalError: table product has no column named product_location.```
I have looked at this page ``https://stackoverflow.com/questions/21881992/when-is-sqliteopenhelper-oncreate-onupgrade-run`` which has a lot about this problem but it is over my head. I don’t usually work with code nearly this big. Wondering if someone could give me an idea what to try that I may understand.
Someone suggested remove if not exist from create table but that did not work
