linkml-sqldb dump doesn't work when using --module argument

[turbomam]

I can't seem to get linkml-sqldb dump to work with the --module argument. It says

UnboundLocalError: local variable 'sv' referenced before assignment

It does work with the --schema argument

See the problematic_sqlite rule in https://github.com/turbomam/linkml-abuse/blob/main/Makefile

I think that's coming from linkml.utils.sqlutils.dump

We should definitely improve the reporting, but I think this works if you specify schema and module or module and target class

just specifying module alone gives insufficient information to know what the top level class to instantiate is

[turbomam]

Thanks. Under what circumstances would it be beneficial to specify the schema and the module (since you can do it with the schema alone)?

I'll try module and target class.

You may wish to avoid the compilation step, perhaps you have dataclasses or pydantic generated some other way. Rare though
