[英]Connecting from Python to SQL Server
I'd like to connect from IPython notebook to a SQL-Server database via integrated security. 我想通过集成的安全性从IPython Notebook连接到SQL-Server数据库。
Is this possible? 这可能吗? I'm guessing yes it is.
我猜是的。
How do I format the connection string in the following? 如何在下面格式化连接字符串?
import pandas as pd
import pandas.io.sql as psql
sql = "SELECT * FROM WHdb.dbo.vw_smallTable"
cnx = "Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=True;Initial Catalog=WHdb;Data Source=OurServerName"
data = psql.read_sql(sql, cnx)
This just gives an error. 这只是一个错误。 Am I going about the
cnx
incorrectly? 我会错误地处理
cnx
吗?
You need to install the package, pypyodbc 您需要安装软件包pypyodbc
!pip install pypyodbc
Then, you can import it as follows: 然后,您可以按以下方式导入它:
import pypyodbc as podbc
You can now create the connection: 您现在可以创建连接:
conn = podbc.connect("Driver={SQL Server};Server=<YourServer>;Database=<YourDatabase>;uid=<YourUserName>;pwd=<YourPassword>"
Finally, you fetch your data as follows: 最后,您按以下方式获取数据:
cursor = conn.cursor()
sql = "SELECT * FROM WHdb.dbo.vw_smallTable"
cursor.execute(sql)
data = cursor.fetchone()
while data:
print(str(data[0]) + ", " + ... + ", " + str(data[n-1]))
data = cursor.fetchone()
conn.close()
Note that n = number of columns in your table. 请注意,n =表中的列数。
This is what worked for me well... 这对我很有效...
import pyodbc
server = 'myserver'
database = 'mydb'
username = 'myusername'
password = 'mypassword'
#Connection String
connection = pyodbc.connect('DRIVER={SQL Server Native Client 11.0};SERVER='+server+';DATABASE='+database+';UID='+username+';PWD='+ password)
cursor = connection.cursor()
#Sample select query
cursor.execute("SELECT @@version;")
row = cursor.fetchone()
while row:
print row[0]
row = cursor.fetchone()
