Connecting to MS SQL Server with Windows Authentication using Python? -


how connect ms sql server using windows authentication, pyodbc library?

i can connect via ms access , sql server management studio, cannot working connection odbc string python.

here's i've tried (also without 'trusted_connection=yes'):

pyodbc.connect('trusted_connection=yes',                driver='{sql server}', server='[system_name]',                database='[databasename]')  pyodbc.connect('trusted_connection=yes', uid='me',                driver='{sql server}', server='localhost',                database='[databasename]')  pyodbc.connect('trusted_connection=yes',                driver='{sql server}', server='localhost',                uid='me', pwd='[windows_pass]', database='[database_name]')  pyodbc.connect('trusted_connection=yes',                driver='{sql server}', server='localhost',                database='[server_name]\\[database_name]')  pyodbc.connect('trusted_connection=yes',                driver='{sql server}', server='localhost',                database='[server_name]\[database_name]')  pyodbc.connect('trusted_connection=yes',                driver='{sql server}',                database='[server_name]\[database_name]')

you can specify connection string 1 long string uses semi-colons (;) argument separator.

working example:

import pyodbc cnxn = pyodbc.connect(r'driver={sql server};server=.\sqlexpress;database=mydb;trusted_connection=yes;') cursor = cnxn.cursor() cursor.execute("select lastname mycontacts") while 1:     row = cursor.fetchone()     if not row:         break     print(row.lastname) cnxn.close()

for connection strings lots of parameters, following accomplish same thing in more readable way:

conn_str = (     r'driver={sql server};'     r'server=.\sqlexpress;'     r'database=mydb;'     r'trusted_connection=yes;'     ) cnxn = pyodbc.connect(conn_str)

(note there no commas between individual string components.)
