これら 3 つすべてを調和させて動作させるのは非常に困難です。さまざまな構成をすべてリストし、テスト コードを添えて、新鮮な目で私の愚かさに気付くことができるかどうかを確認します。

12.04 Ubuntu Server を実行していますが、MSSQL Server 2008 に接続しようとしていて、PyODBC で使用することになります。

ただ、入れるだけの時は

tsql -S T2 -U Foo -P Bar

や。。など。

とにかく、誰かが助けてくれるなら (そして、このもやを晴らすことができれば、私は永遠に感謝します)、これが私の現在の設定です。

これは私の /etc/odbc.ini です

[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       =

以下は私の /etc/odbcinst.ini です

[FreeTDS]
Description=FreeTDS Driver
Driver=/usr/lib/odbc/libtdsodbc.so
Setup=/usr/lib/odbc/libtdsS.so
CPTimeout=
CPReuse=
FileUsage=1

以下は私のfreetds.confです

# 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

そして、私のPythonテストファイルは、適切な測定のために

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)

UnixODBC を使用して PHP 経由でさまざまなデータベースに接続しています。Microsoft SQL Server の構成は次のとおりです。

/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

次に、接続をテストします。

isql mssql username password

環境によっては、usernameドメイン\ユーザー名の形式にする必要がある場合があります。

コマンドを発行すると、次のように表示されます。
