You can do this with



def execute_comparison(db_api, sql):
    if db_api.sql_dialect.sql_dialect_str == "duckdb":
        con = db_api._con
        sql = f"COPY ({sql}) TO '/dev/null';"
        con.execute(sql)
    else:
        spark = db_api.spark
        df = spark.sql(sql)
        df.write.format("noop").mode("overwrite").save()

but i've tried it and in practice it doesn't make a difference to the results
