## Which issue does this PR close? COPY TO does not produce a single output file for a zero rows query - Closes #18073 ## Rationale for this change Executing following sql does not effectively create a single output file on disk : COPY (SELECT 1 AS id WHERE FALSE) TO 'table_no_rows.parquet'; I would expect it creates a parquet file containing 0 rows including the schema metadata. The fact you can still query the schema of such a table is still valuable information. ## What changes are included in this PR? ## Are these changes tested? Additional COPY TO test added in the copy.slt sqllogictests ## Are there any user-facing changes? A zero rows file will be created now -- This is an automated message from the Apache Git Service.
