L013 seems to expect an alias for the `*` when subsequent columns are present

test.sql

select
    *,
    'string' as extra_column
from
    my_table

$ sqlfluff lint test.sql
== [test.sql] FAIL
L:   2 | P:   5 | L013 | Column expression without alias. Use explicit `AS`
                       | clause.

The linting passes if I don’t include extra_column in the select

This is definitely a bug, but I’m curious as to how it happens. I think it must be that there’s something fundamental about how the parse tree is structured in the two cases. This one needs more investigation.

Next step here is to run sqlfluff parse on each of the two queries and understand why select * from blah means that the * is not parsed as an expression, but select *, foo from blah means that * is parsed as an expression. 🤔

Y’all are too quick on the draw! Would love to contribute in a future issue, thanks for addressing this so quickly 🏋️‍♂️
