Question

我有两个相同列的表。我正在尝试删除table2'600_LONDON_NUMBER'中的行，这些行位于table2'600_LONDON_NUMBER1'中。下面是我的查询，但当我运行它时，MS Access说“无法从指定的表中删除”。请帮忙

15 <nil>

P.S。当我为同一个查询运行DELETE [600_LONDON_NUMBER].* FROM 600_LONDON_NUMBER INNER JOIN 600_LONDON_NUMBER1 ON ([600_LONDON_NUMBER].GFCID = [600_LONDON_NUMBER1].GFCID) AND ([600_LONDON_NUMBER].CUSTBaseNO = [600_LONDON_NUMBER1].[CUST Base NO]);语句时，它会在没有任何问题的情况下重新检索数据。我还检查了数据不是SELECT我可以使用简单的readonly查询删除。

您可以使用DELETE 600_LONDON_NUMBER.* FROM 600_LONDON_NUMBER WHERE EXISTS ( SELECT 1 FROM 600_LONDON_NUMBER1 WHERE [600_LONDON_NUMBER].GFCID = [600_LONDON_NUMBER1].GFCID) AND [600_LONDON_NUMBER].CUSTBaseNO = [600_LONDON_NUMBER1].[CUSTBaseNO] )来解决它

from cherrypy.lib import auth_digest

USERS = {'jon': 'secret'}

conf = {
   '/protected/area': {
        'tools.auth_digest.on': True,
        'tools.auth_digest.realm': 'localhost',
        'tools.auth_digest.get_ha1': auth_digest.get_ha1_dict_plain(USERS),
        'tools.auth_digest.key': 'a565c27146791cfb'
   }
}

cherrypy.quickstart(myapp, '/', conf)

我的DELETE查询有什么问题
