Question

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


        

Answer 1

if any one are trying to access the database which is hosted in azure then try to give the driver as ODBC Driver 17 for SQL Server

Answer 2

for error : pyodbc.InterfaceError: ('IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) (SQLDriverConnect)')

No space between the driver and event

connection = Driver={SQL Server Native Client 11.0}; "Server=servername;" "Database=dbname;" "Trusted_Connection=yes;"

Answer 3

You could try:

import pyodbc
# Using a DSN
cnxn = pyodbc.connect('DSN=odbc_datasource_name;UID=db_user_id;PWD=db_password')

Note: You will need to know the "odbc_datasource_name". In Windows you can search for ODBC Data Sources. The name will look something like this:

Answer 4

I am also getting same error. Finally i have found the solution.

We can search odbc in our local program and check for version of odbc. In my case i have version 17 and 11 so. i have used 17 in connection string

'DRIVER={ODBC Driver 17 for SQL Server}'

Answer 5

I have had the same error on python3 and this help me:

conn = pyodbc.connect('DRIVER={ODBC Driver 17 for SQL Server};'
                      'SERVER=YourServerName;'
                      'DATABASE=YourDatabaseName;UID=USER_NAME;PWD=PASS_WORD;')

remember python is case-sensitive so you have to mention DRIVER,SERVER,... in upper case. and you can visit this link for more information:

Answer 6

Create a DSN something like this (ASEDEV) for your connection and try to use DSN instead of DRIVER like below:

enter code here
import pyodbc
cnxn = pyodbc.connect('DSN=ASEDEV;User ID=sa;Password=sybase123')
mycur = cnxn.cursor()
mycur.execute("select * from master..sysdatabases")
row = mycur.fetchone()
while row:
    print(row)
    row = mycur.fetchone()`
