Maybe this? https://pgloader.readthedocs.io/en/latest/ref/sqlite.html

Also what have you tried, and how did it fail?

I have tried it. Getting this error: The value NIL is not of type STRING when binding STRING

You need to provide a password in the connection string. https://pgloader.readthedocs.io/en/latest/pgloader.html?highlight=password#connection-string

Thanks man. It worked

You might need to handle NULL values by explicit type casting

I exported the file in db drowser for sqlite into an sql file. When I tried importing in mysql workbench, i am getting this error: Error executing SQL script. '>' not supported between instances of 'NoneType' and 'int'.

Great webdev question /s

[–] [email protected] 3 points 1 year ago (1 children)

Yeah I know. I didn't find better suitable community on lemmy. It's the closest one I got. Also searching for communities is little harder on lemmy.

Makes sense. I still haven't really figured out how searching works either.

Actually, yes it's a fitting question unless you define webdev as just creating websites that might query an api via js.

The services that provide this apis are just as much part of our domain and basic knowledge about the other end of a communication channel benefits everyone.
