在将Pandas Dataframe插入python的Sql-server DB中时需要帮助 [英] Need help in inserting Pandas Dataframe into Sql-server DB in python
问题描述
我正在尝试使用dataframe.to_SQL将熊猫数据框CAPE
插入到SQL Server
DB中.我已经提到了以下解决方案来插入行.
PyOdbc无法连接到sql服务器实例.但是我在urllib.parse.quote_plus
行中遇到了错误.
I am trying to insert pandas dataframe CAPE
into SQL Server
DB using dataframe.to_SQL. I have referred the following solution to insert rows.
PyOdbc fails to connect to a sql server instance .But i am getting error in urllib.parse.quote_plus
line.
任何人都可以帮助提供一种在Sql-server DB中插入数据框的解决方案.
Can anyone help provide a solution to insert dataframe in Sql-server DB.
源代码:
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')
这是我得到的错误:

File "<input>", line 1, in <module>

我正在使用SQL Server 13.0.4版
I am using SQL server version 13.0.4
版本2:
我已经更新了我的代码.现在给出sqlalchemy.exc.DBAPIError:
I have updated my code. Now its giving sqlalchemy.exc.DBAPIError:
代码:
import pyodbc
import sqlalchemy
CAFE # sample dataframe
engine = sqlalchemy.create_engine("mssql+pyodbc://SQL_User:Greentableau!@GIRSQL.GIRCAPITAL.com/Tableau?driver=SQL+Server+Native+Client+11.0")
engine.connect()
CAPE.to_sql(name='[Tableau].[dbo].[Test_table]',con=engine, if_exists='replace')
错误:
sqlalchemy.exc.DBAPIError: (pyodbc.Error) ('IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) (SQLDriverConnect)')
推荐答案
AFAIK不需要引用连接字符串.
AFAIK there is no need to quote a connection string.
以下是 SQL Alchemy在线文档:
engine = create_engine("mssql+pyodbc://scott:tiger@myhost:port/databasename?driver=SQL+Server+Native+Client+10.0")
即我们不必直接调用/使用PyODBC-SQL Alchemy将为我们做到这一点...
I.e. we don't have to call/use PyODBC directly - SQL Alchemy will do it for us...
PS 驱动程序名称将取决于您的SQL Server版本...
