## Which issue does this PR close? - Closes #15386 . ## Rationale for this change for sql ``` with test AS (SELECT i as needle FROM generate_series(1, 10) t(i)) select count(*) from test WHERE 1 = 1; ``` The root cause is that after `optimize_projections`. columns are dropped from logical plan, but in physical plan, there is still a value column. ## What changes are included in this PR? I think current `optimize_projections` is correct. it's a corner case, just need to bypass the check schema when physical_schema.fields.len() == 1 && logical_schema.fields.len() == 0. ## Are these changes tested? UT ## Are there any user-facing changes? No -- This is an automated message from the Apache Git Service.
