Having Troubles with UnixODBC, FreeTDS, and PyODBC
I connect to various databases via PHP using UnixODBC, here is my configuration for a Microsoft SQL Server:
/etc/odbc.ini
# Define a connection to a Microsoft SQL server
# The Description can be whatever we want it to be.
# The Driver value must match what we have defined in /etc/odbcinst.ini
# The Database name must be the name of the database this connection will connect to.
# The ServerName is the name we defined in /etc/freetds/freetds.conf
# The TDS_Version should match what we defined in /etc/freetds/freetds.conf
[mssql]
Description = MSSQL Server
Driver = freetds
Database = XXXXXX
ServerName = MSSQL
TDS_Version = 8.0
/etc/odbcinst.ini
# Define where to find the driver for the Free TDS connections.
[freetds]
Description = MS SQL database access with Free TDS
Driver = /usr/lib/i386-linux-gnu/odbc/libtdsodbc.so
Setup = /usr/lib/i386-linux-gnu/odbc/libtdsS.so
UsageCount = 1
/etc/freetds/freetds.conf
# The basics for defining a DSN (Data Source Name)
# [data_source_name]
# host = <hostname or IP address>
# port = <port number to connect to - probably 1433>
# tds version = <TDS version to use - probably 8.0>
# Define a connection to the Microsoft SQL Server
[mssql]
host = XXXXXX
port = 1433
tds version = 8.0
Then test your connection:
isql mssql username password
Depending on your environment your username
might have to be in the format: domain\username
After issuing the command you should see something like:
+---------------------------------------+
| Connected! |
| |
| sql-statement |
| help [tablename] |
| quit |
| |
+---------------------------------------+

I am having great difficulty getting all three of these to work together in harmony. I guess I'll list all the various configurations, along with the test code to see if a pair of fresh eyes can realize my stupidity.
I'm running 12.04 Ubuntu Server and I'm trying to connect to a MSSQL Server 2008 and end up using it with PyODBC.
However, when just putting in
tsql -S T2 -U Foo -P Bar
I get the
1> 2> 3> 4> 5> 6> 7> 8> 9> 10> 11>
and etc.
Anyway, if anyone would be able to help (and I would be eternally grateful if you can clear me of this haze), here are my current configurations.
This is my /etc/odbc.ini
[ODBC Data Sources] odbcname = MySQL T2 = MSSQL [odbcname] Driver = /usr/lib/odbc/libmyodbc.so Description = MyODBC 3.51 Driver DSN SERVER = Foobar PORT = 3306 USER = Foo Password = Bar Database = Foobar OPTION = 3 SOCKET = [T2] Driver = FreeTDS Description = ODBC connection via FreeTDS SERVER = FOOBAR PORT = 1433 USER = Foo Password = Bar Database = Foobar OPTION = 3 SOCKET = [Default] Driver = /usr/local/lib/libmyodbc3.so Description = MyODBC 3.51 Driver DSN SERVER = FOOBAR PORT = 3306 USER = foo Password = bar Database = FOOBAR OPTION = 3 SOCKET =
The following is my /etc/odbcinst.ini
[FreeTDS] Description=FreeTDS Driver Driver=/usr/lib/odbc/libtdsodbc.so Setup=/usr/lib/odbc/libtdsS.so CPTimeout= CPReuse= FileUsage=1
The following is my freetds.conf
# This file is installed by FreeTDS if no file by the same # name is found in the installation directory. # # For information about the layout of this file and its settings, # see the freetds.conf manpage "man freetds.conf". # Global settings are overridden by those in a database # server specific section [global] # TDS protocol version ; tds version = 4.2 # Whether to write a TDSDUMP file for diagnostic purposes # (setting this to /tmp is insecure on a multi-user system) ; dump file = /tmp/freetds.log ; debug flags = 0xffff # Command and connection timeouts ; timeout = 10 ; connect timeout = 10 # If you get out-of-memory errors, it may mean that your client # is trying to allocate a huge buffer for a TEXT field. # Try setting 'text size' to a more reasonable limit #text size = 64512 [T2] host = FOOBAR port = 1433 tds version = 7.0 client charset = UTF-8 text size = 20971520 [global] # TDS protocol version tds version = 7.0
And my Python test file just for good measure
import pyodbc import sys try: #tempsystrends = pyodbc.connect('DRIVER=FreeTDS;SERVER=FOOBAR;PORT=1433;DATABASE=T2;UID=FOO;PWD=bar;TDS_Version=7.0;') cursor = tempsystrends.cursor() except pyodbc.Error as e: print "Error: %s" % (e.args[1]) sys.exit(1)

philshem over 10 yearsWOW. This is perhaps the most complete answer I've ever read on Stack Overflow. Only change for me was to change the location for 64bit in /etc/odbcinst.ini: /usr/lib/x86_64-linux-gnu/odbc/libtdsodbc.so
