All columns are selected by default?

When I print out the raw sql command, I found that all columns are selected. Does it make sense?

I think only those specified from the frontend should be included. The following command is how I get the raw sql.

`print(query.statement.compile(compile_kwargs={"literal_binds": True}))`

Thanks.

Start with the GraphQL-to-SQLAlchemy query construction that produces the statement shown by query.statement.compile(compile_kwargs={"literal_binds": True}). Trace how frontend-selected fields are represented and determine whether unrequested columns can be excluded. Done means the generated SQL selects only requested fields, with a regression test covering that behavior.
