为什么MSSQL不将数据返回给CherryPy？

Question

这是我的代码：

...

CDN_XL = Database('mssql', CDN_XL_HOST, CDN_XL_PORT, CDN_XL_NAME, CDN_XL_USER, CDN_XL_PASS)

...

def GET(self):
    user = USER
    if user is None:
        raise cherrypy.HTTPError(401, "NOT_AUTHORIZED")
    with CDN_XL:
        CDN_XL.execute("""Select TrN_DokumentObcy, TrN_NettoR, ToPay, trn_data, trp_termin, data_roz, b_1, b_3, b_4, b_7, b_8, b_9 from(Select DISTINCT TrN_DokumentObcy, TrN_NettoR, SUM(TrP_Pozostaje) as ToPay, DATEADD(day, TrN_Data2, CONVERT(date, '1800-12-28', 120)) as trn_data, DATEADD(day, TrP_Termin, CONVERT(date, '1800-12-28', 120)) trp_termin, DATEADD(day, TrN_DataRoz, CONVERT(date, '1800-12-28', 120)) as data_roz, DATEADD(day, 1, DATEADD(day, TrP_Termin, CONVERT(date, '1800-12-28', 120))) as b_1, DATEADD(day, 3, DATEADD(day, TrP_Termin, CONVERT(date, '1800-12-28', 120))) as b_3, DATEADD(day, 4, DATEADD(day, TrP_Termin, CONVERT(date, '1800-12-28', 120))) as b_4, DATEADD(day, 7, DATEADD(day, TrP_Termin, CONVERT(date, '1800-12-28', 120))) as b_7, DATEADD(day, 8, DATEADD(day, TrP_Termin, CONVERT(date, '1800-12-28', 120))) as b_8, DATEADD(day, 9, DATEADD(day, TrP_Termin, CONVERT(date, '1800-12-28', 120))) as b_9, DATEADD(day, 10, DATEADD(day, TrP_Termin, CONVERT(date, '1800-12-28', 120))) as b_10, DATEADD(day, 14, DATEADD(day, TrP_Termin, CONVERT(date, '1800-12-28', 120))) as b_14, DATEADD(day, 15, DATEADD(day, TrP_Termin, CONVERT(date, '1800-12-28', 120))) as b_15, DATEADD(day, 22, DATEADD(day, TrP_Termin, CONVERT(date, '1800-12-28', 120))) as b_22, DATEADD(day, 23, DATEADD(day, TrP_Termin, CONVERT(date, '1800-12-28', 120))) as b_23, DATEADD(day, 40, DATEADD(day, TrP_Termin, CONVERT(date, '1800-12-28', 120))) as b_40, DATEADD(day, 41, DATEADD(day, TrP_Termin, CONVERT(date, '1800-12-28', 120))) as b_41, DATEADD(day, 70, DATEADD(day, TrP_Termin, CONVERT(date, '1800-12-28', 120))) as b_70 FROM CDN.TraNag, CDN.TraPlat where (TrN_DokumentObcy LIKE 'FS-%' OR TrN_DokumentObcy LIKE 'FSK-%') AND TrN_DokumentObcy NOT LIKE '%/R/%' AND TrN_DokumentObcy NOT LIKE '%/ORG/%' AND TrN_DokumentObcy NOT LIKE '%/CPW/%' AND TrN_DokumentObcy NOT LIKE '%/MC/%' AND TrN_DokumentObcy NOT LIKE '%/INST/%' AND TrN_DokumentObcy <> '' AND TrN_GIDTyp = TrP_GIDTyp and TrN_GIDNumer=trp_gidnumer GROUP BY TrN_DokumentObcy, TrN_Data2, TrN_NettoR, TrN_DataRoz, TrP_Termin) as x Where trn_data >= DATEADD(mm,DATEDIFF(mm,0,GETDATE())-2,0) AND trn_data < DATEADD(mm,DATEDIFF(mm,0,GETDATE())-1,0);""")
        CDN_XL.conn.commit()
        logging.debug(CDN_XL.cur.rowcount)
        types = CDN_XL.cur.fetchall()
        information_json = []
    if types is not None and len(types) > 0:

        for typ in types:
            information_json.append({"numberFactures": str(typ["FactureNumbers"]), "sum": str(typ["SumNetto"])})

        output_json = {"payment_list":information_json}
        return json.dumps(output_json, ensure_ascii=False)
    else:
        raise cherrypy.HTTPError(404, "NOT FOUND")

这部分

logging.debug(CDN_XL.cur.rowcount)

返回-1

POSTMAN返回此：

{"payment_list": [{"sum": "None", "numberFactures": "0"}]}

DBeaver返回以下内容：

如果我使用其他查询exp。 “ SELECT A，B FROM X”有效，所以为什么在Dbeavear中此查询有效，但是当我想传递给CherryPy并使用POSTMAN时却没有。我真的不明白
