嘗試使用to_sql函數插入時，數據庫引擎無法連接到sql-server實例

我試圖使用dataframe.to_SQL將pandas數據框CAPE插入到SQL Server數據庫中。我已經提到以下解決方案來插入行。 PyOdbc fails to connect to a sql server instance 嘗試使用to_sql函數插入時，數據庫引擎無法連接到sql-server實例

但是我收到如下所示的錯誤。

的源代碼：

CAPE # Input dataframe 
    connection = pdc.connect('Driver={SQL Server};''Server=GIRSQL.GIRCAPITAL.com;''Database=Tableau;''uid=SQL_User;pwd=Greentableau!') 
    connection_string = urllib.parse.quote_plus(connection) 
    connection_string = "mssql+pyodbc:///?odbc_connect=%s" % connection_string 
    engine = sq.create_engine(connection_string) 
    CAPE.to_sql(engine, name='[Tableau].[dbo].[Company_Table]',if_exists='replace')

這是我收到的錯誤：

的DataFrame.to_sql()第一個位置參數是一個表名，你通過了engine（SQLAlchemy對象）作爲第一個參數。

那麼試試這個來代替：

CAPE.to_sql('[Tableau].[dbo].[Company_Table]',con=engine, if_exists='replace')

我在 'urllib.parse.quote_plus（）' 行收到錯誤，呼籲to_sql之前。有沒有更好的方法來將數據幀插入Sql-server Db –

我已將我的代碼更改爲以下 'params = urllib.parse.quote_plus（「DRIVER = {SQL Server}; SERVER = GIRSQL.GIRCAPITAL.com; DATABASE = Tableau; UID = SQL_User; PWD = Greentableau！「） engine = sqlalchemy.create_engine（」mssql + pyodbc：///？odbc_connect =％s「％params） engine.connect（） df.to_sql（name =' [Tableau]。[dbo]。[Test table]'，con = engine，index = False，if_exists ='append'）' 現在工作正常 –
