data source' for pyodbc? up vote 14 down vote favorite 5 I'm trying to connect to an MSSQL database from python on Linux (SLES). I have installed pyodbc and Free TDS. From the command line: tsql -H server -p 1433 -U username -P password Connects to the server without a problem, however, from Python: import pyodbc pyodbc.connect(driver='{FreeTDS}', server='server', database='database', uid='username', pwd='password') Yields an error: pyodbc.Error: ('08001', '[08001] unable to connect to data source report builder [unixODBC][FreeTDS][SQL Server]Unable to connect to data source (0) (SQLDriverConnect)') I'm finding this error unhelpfully vague. Even a suggestion to narrow down the issue would be helpful right now. Edit: Looking at the TDS log dump it looks like this is where the whole thing falls apart: token.c:328:tds_process_login_tokens() util.c:331:tdserror(0x87bbeb8, 0x8861820, 20017, 115) odbc.c:2270:msgno 20017 20003 util.c:361:tdserror: client library returned TDS_INT_CANCEL(2) util.c:384:tdserror: returning TDS_INT_CANCEL(2) util.c:156:Changed query state from IDLE to DEAD token.c:337:looking for login token, got 0() token.c:122:tds_process_default_tokens() marker is 0() token.c:125:leaving tds_process_default_tokens() connection dead login.c:466:login packet accepted util.c:331:tdserror(0x87bbeb8, 0x8861820, 20002, 0) odbc.c:2270:msgno 20002 20003 util.c:361:tdserror: client library returned TDS_INT_CANCEL(2) util.c:384:tdserror: returning TDS_INT_CANCEL(2) mem.c:615:tds_free_all_results() error.c:412:odbc_errs_add: "Unable to connect to data source" python database tsql database-connection pyodbc share|improve this question edited Mar 18 '12 at 0:07 asked Mar 15 '12 at 16:09 pbaehr 3661210 add a comment| 7 Answers 7 active oldest votes up vote 13 down vote I try with: MS SQL 2008 Datacenter Ubuntu 12.04 TLS (amd64) Python 2.7 And this works for me: Test connection: tsql -H 10.19.4.42 -p 1433 -U DAVIDG -P 123456 on /etc/odbcinst.ini add: [ODBC] Trace = Yes TraceFile = /tmp/odbc.log [FreeTDS] Description = TDS driver (Sybase/MS SQL) Driver = /usr/lib/x86_64-linux-gnu/odbc/libtdsodbc.so Setup = /usr/lib/x86_64-linux-gnu

FreeTDS has its configuration (freetds.conf). ODBC configuration could be either DSN based or connection https://bytes.com/topic/sql-server/answers/144188-odbc-connection-sql-server-failing string based (this is true even for Windows) and you can also have a connection string based that points to your DSN. Adding FreeTDS to odbc make things unable to more complicated as your DSN or your connection string can point to FreeTDS configuration. Now your files seem to indicate that your DSN (odbc.ini) points to FreeTDS (Servername attribute in either connection string or as DSN entries) however you are using a full connection string in your Perl program. So, if your connection line is unable to connect $dsn = "dbi:ODBC:DRIVER={FreeTDS};Server=$server;database=$database;"; $server should be a real server (even ip address). If you want to use your "SERVER" in odbc.ini you have to specify something like $dsn = "dbi:ODBC:DSN=SERVER;"; or just $dsn = "dbi:ODBC:SERVER"; You could even specify a full connection string but probably you want something like $dsn = "dbi:ODBC:DRIVER={FreeTDS};Server=$server;Port=1433;TDS_Version=7.2;database=$database;"; where $server is an dns hostname or an ip. Note that in this case odbc.ini and freetds.conf are not used (here odbcinst.ini is used to find the odbc driver given the name). Frediano 2012/12/14 Sankar G

ODBC connection to SQL server failing P: n/a Dan Hi, I have an access 2003 database which connect to sql server via a DSN that goes through a VPN. The database works fine and everyone can coonect from their normal computers but for anyone working on their Laptops (IBM Think Pad T42's) they cannnot connect to the datasource. The DSN fails upon connection attempt with : Connection Failed: SQLState: '01000' SQL Server Error: 1326 [Microsoft][ODBC SQL Server Driver][DBNETLIB]ConnectionOpen (Connect()). Connection Failed: SQLState: '08001' SQL Server Error: 17 [Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access is denied. This has been driving me insane as i cannot understand why it works for our desktop computers and not for our laptops. The version of MDAC is the same on a computer that connects as it is on a laptop that doesn't. TCP/IP is enabled on the server and is using the default 1433 port. severs, desktops and laptops all patches and up to date with the latest SP's. DSN has been dropped and re-created. Domain user has been put in localAdmin group for laptop. I hope i'm mising something really obvious....can someone please please put me out of my misery and tell me they have come accross this before and have a solution. Ive tried everything i can think of.
