在我的公司中,我们有一个MongoDB集合,其中包含有关电源的一些信息。我正在尝试使用python scritp来获取该信息并将其放入MySQL DB。
问题是在将数据加载到MySQL时出现错误。这是错误:
回溯(最近通话最近):文件 “ C:\ Users \ ngabioud \ AppData \ Local \ Programs \ Python \ Python37 \ lib \ site-packag es \ mysql \ connector \ conversion.py“,行179,在to_mysql中 返回getattr(self,“ _ {0} _to_mysql” .format(type_name))(value)AttributeError:'MySQLConverter'对象没有属性 '_int64_to_mysql'
在处理上述异常期间,发生了另一个异常:
回溯(最近通话最近):文件 “ C:\ Users \ ngabioud \ AppData \ Local \ Programs \ Python \ Python37 \ lib \ site-packag es \ mysql \ connector \ cursor.py“,第417行,在_process_params中 res = [to i的to_mysql(i)in res]文件“ C:\ Users \ ngabioud \ AppData \ Local \ Programs \ Python \ Python37 \ lib \ site-packag es \ mysql \ connector \ cursor.py“,第417行,在 res = [to i的to_mysql(i)in res]文件“ C:\ Users \ ngabioud \ AppData \ Local \ Programs \ Python \ Python37 \ lib \ site-packag es \ mysql \ connector \ conversion.py“,第182行,在to_mysql中 “ MySQL type” .format(type_name))TypeError:无法将Python'int64'转换为MySQL类型
在处理上述异常期间,发生了另一个异常:
回溯(最近通话最近):文件“ Fuentes y tickets ME.py”, 第114行,在 mycursor.execute(querysql,queryval)文件“ C:\ Users \ ngabioud \ AppData \ Local \ Programs \ Python \ Python37 \ lib \ site-packag es \ mysql \ connector \ cursor.py“,第539行,在执行中 psub = _ParamSubstitutor(self._process_params(params))文件“ C:\ Users \ ngabioud \ AppData \ Local \ Programs \ Python \ Python37 \ lib \ site-packag es \ mysql \ connector \ cursor.py“,第422行,在_process_params中 “失败的处理格式参数;%s”%err)mysql.connector.errors.ProgrammingError:处理失败 格式参数Py thon'int64'无法转换为MySQL类型
然后,这是python代码:
idFuente = x['idFuente'] #Tried np.int64(x['idFuente']) but still not working
direccion = x['direccion']['calle'] + " " + str(x['direccion']['nro'])
nodoUbicacion = x['direccion']['nodoUbic']
nodoAlimenta = x['nodoAlimenta']
tieneTransponder = x['tieneTransponder']
tuvoTransponder = x['tuvoTransponder']
macTp = x['macTp']
tieneBaterias = x['tieneBaterias']
tuvoBaterias = x['tuvoBaterias']
try:
tp_psBatteriesPerString = x['info_poleo']['tp_psBatteriesPerString']
tp_psBatteryVoltage_String_1_Battery_1 = x['info_poleo']['tp_psBatteryVoltage_String_1_Battery_1']
tp_psBatteryVoltage_String_1_Battery_2 = x['info_poleo']['tp_psBatteryVoltage_String_1_Battery_2']
tp_psBatteryVoltage_String_1_Battery_3 = x['info_poleo']['tp_psBatteryVoltage_String_1_Battery_3']
tp_psBatteryVoltage_String_2_Battery_1 = x['info_poleo']['tp_psBatteryVoltage_String_2_Battery_1']
tp_psBatteryVoltage_String_2_Battery_2 = x['info_poleo']['tp_psBatteryVoltage_String_2_Battery_2']
tp_psBatteryVoltage_String_2_Battery_3 = x['info_poleo']['tp_psBatteryVoltage_String_2_Battery_3']
tp_psTotalStringVoltage = ['info_poleo']['tp_psBatteryVoltage_String_2_Battery_3']
except:
tp_psBatteriesPerString = None
tp_psBatteryVoltage_String_1_Battery_1 = None
tp_psBatteryVoltage_String_1_Battery_2 = None
tp_psBatteryVoltage_String_1_Battery_3 = None
tp_psBatteryVoltage_String_2_Battery_1 = None
tp_psBatteryVoltage_String_2_Battery_2 = None
tp_psBatteryVoltage_String_2_Battery_3 = None
tp_psTotalStringVoltage = None
querysql = "INSERT INTO fuentes (`idFuente`, `direccion`, `nodoUbicacion`, `nodoAlimenta`, `tieneTransponder`, `tuvoTransponder`, `macTp`, `tieneBaterias`, `tuvoBaterias`, `tp_psBatteriesPerString`, `tp_psBatteryVoltage_String_1_Battery_1`, `tp_psBatteryVoltage_String_1_Battery_2`, `tp_psBatteryVoltage_String_1_Battery_3`, `tp_psBatteryVoltage_String_2_Battery_1`, `tp_psBatteryVoltage_String_2_Battery_2`, `tp_psBatteryVoltage_String_2_Battery_3`, `tp_psTotalStringVoltage`, `fechaCarga`) VALUES(%s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s)"
queryval= (idFuente, direccion,nodoUbicacion,nodoAlimenta,tieneTransponder,tuvoTransponder, macTp, tieneBaterias, tuvoBaterias, tp_psBatteriesPerString, tp_psBatteryVoltage_String_1_Battery_1,tp_psBatteryVoltage_String_1_Battery_2,tp_psBatteryVoltage_String_1_Battery_3,tp_psBatteryVoltage_String_2_Battery_1,tp_psBatteryVoltage_String_2_Battery_2,tp_psBatteryVoltage_String_2_Battery_3,tp_psTotalStringVoltage,fechaCarga)
mycursor.execute(querysql, queryval)
这是MySQL表结构:
这是来自MongoDB结果的示例:
我在哪里失败?我是否需要转换数据类型?我该怎么做?我正在使用pymongo和mysql.connector
谢谢!
答案 0 :(得分:0)
我按照@DDhaliwal的建议进行了工作,并且奏效了。
idFuente = int(x['idFuente'])
谢谢!
