Does SWIRL have a version that runs on Windows? I always encounter errors when running it on Windows.

Hi Wolfboyccc,

what exactly is the issue you are facing?

[Wolfboyccc]

I want to know if my modifications regarding make_command and the cmd part are correct, as it seems like the operation of creating tables didn't execute, and I'm getting an error about an empty table.

[Wolfboyccc]

Through my debugging, I found that the value of self.columns becomes empty after running a filtering operation at line 25 of a schema.py. This is causing the issue of getting empty rows.
for filter_name in filters.keys():
filter_class = getattr(importlib.import_module("swirl.schema"), filter_name)
filter_instance = filter_class(filters[filter_name], self.database_name)
self.columns = filter_instance.apply_filter(self.columns)

Does is run without those modifications? I doubt I will abe able to debug your code from screenshots.

The issue regarding 'make_command' and 'cmd' has been resolved. It may have been due to the absence of the 'make' command in Windows. I downloaded Mingw64 and changed the command to 'make'. The current problem is that 'Self.columns' gets filtered out as empty when running the following filter code at line 25 of a schema.py, ultimately leading to issues

Can you please check if there is data loaded in Postgres? The query should return something.

I have checked the Postgres database and, after the creation operation, generated a database called indexselection_tpch___10. There are eight tables in this database, but each table has very few columns, so they should all have been filtered out. I would like to inquire about which part of the table creation process went wrong.

Do the tables have any rows?
