将熊猫数据框加载到SQL Server 2012

Question

我尝试将pandas数据框加载到SQL Server。数据框包含以下列：

• userId-int
• saleId-int
• regTime-int
• countryId-int

cnxn = pyodbc.connect('DRIVER={ODBC Driver 17 for SQL Server};SERVER='+server+';DATABASE='+database+';UID='+username+';PWD='+ password)
cursor = cnxn.cursor()
for index, row in users.iterrows():
     cursor.execute('INSERT INTO [dbo].[users]([userId],[saleId],[regTime],[countryId]) values (?,?,?,?)', 
                     row['userId'], 
                     row['saleId'], 
                     row['regTime'],
                     row['countryId'])
     cnxn.commit()
cursor.close()
cnxn.close()

但是我有以下错误：

---------------------------------------------------------------------------
ProgrammingError                          Traceback (most recent call last)
<ipython-input-103-383c1873cad8> in <module>
      4                     row['saleId'],
      5                     row['regTime'],
----> 6                     row['countryId'])
      7     cnxn.commit()
      8 cursor.close()

ProgrammingError: ('Invalid parameter type.  param-index=0 param-type=numpy.int64', 'HY105')

countryId列的值从0到9（代码）

我该如何纠正？
