dataframe.to_SQLを使用してSQL Server
DBにCAPE
のパンダを挿入しようとしています。私は行を挿入するために次の解決策を参照しました。 PyOdbc fails to connect to a sql server instanceデータベースエンジンがto_sql関数を使用して挿入しようとしているときにSQL Serverインスタンスに接続できません
ただし、次のようなエラーが表示されます。
ソースコード:
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')
これは私が取得していますエラーです:

。 SQL Serverにデータフレームを挿入するための良い方法はありますか? –
私のコードを次のように変更しました params = urllib.parse.quote_plus( "DRIVER = {SQL Server}; SERVER = GIRSQL.GIRCAPITAL.com; DATABASE = (%= "%s"%params) engine.connect() df.to_sql(name = 'Tablet; UID = SQL_User; PWD = Greentableau! [Tableau]。[dbo]。[テストテーブル] '、con = engine、index = False、if_exists =' append ')' –
