PYODBC--Data source name not found and no default driver specified

Question

import pyodbc
connection = pyodbc.connect(\'Driver = {SQL Server};Server=SIWSQL43A\\SIMSSPROD43A;\'
                            \'Database=CSM_reporting;Trusted_Conn         


        

Answer 1

Do not put a space after the Driver keyword in the connection string.

This fails on Windows ...

conn_str = (
    r'DRIVER = {SQL Server};'
    r'SERVER=(local)\SQLEXPRESS;'
    r'DATABASE=myDb;'
    r'Trusted_Connection=yes;'
)
cnxn = pyodbc.connect(conn_str)

... but this works:

conn_str = (
    r'DRIVER={SQL Server};'
    r'SERVER=(local)\SQLEXPRESS;'
    r'DATABASE=myDb;'
    r'Trusted_Connection=yes;'
)
cnxn = pyodbc.connect(conn_str)
